Hi David/VTK'ers, 

Following on from my previous email i am now having diffcultly using a more complicated data structure in a derived class. In this case i am trying:

#include "vtkImageData.h"
#include <boost/python.hpp>

class VTK_EXPORT vtkImageDataDict: public vtkImageData
{
public:

  vtkTypeMacro(vtkImageDataDict, vtkImageData);

  // New method
  static vtkImageDataDict *New();

  // Python dictionary
  boost::python::dict m_dict;

  // test function to set the dictionary
  void test_set_dict();

  // prints the dictionary
  void printImageDict();

  // Dictionary getter
  boost::python::dict getDict(){return this->m_dict;}

  // Dictionary setter
  void setDict(boost::python::object dd);
};


When I wrap the above class the test_set_dict and printImageDict work fine but the wrapper seems to ignore getDict()
and setDict(). I assume this is because vtkWrapperPython does not know what to do with boost::python objects. Maybe I am going about this the wrong way? I did try doing the wrapping through boost python rather than VTK but found I ran into compilation issues. 

Any help would be very much appreciated. 

Kit

Hi list,

in my previous VTK code I was successfully using 
vtkImageActor::GetDisplayBounds() and vtkOutlineSource etc. to draw an 
outline around the currently shown 2D slice. After refactoring to 
vtkImageResliceMapper and vtkImageSlice, I have not found a matching 
function: vtkImageResliceMapper::GetBounds() contains a comment "Modify 
to give just the slice bounds" and indeed always returns the bounds of 
the 3D input image.

Any suggestions?

Thanks,

     Sophonet

Try declaring m_dict as a PyObject:

  PyObject *m_dict;
  PyObject *getDict();
  void setDict(PyObject *);

That works. Discovered I  can still use the boost:python for storage containers as long as the methods pass PyObject pointers.

class VTK_EXPORT vtkImageDataDict: public vtkImageData
{
public:

  vtkTypeMacro(vtkImageDataDict, vtkImageData);

  // New method
  static vtkImageDataDict *New();

  // Python dictionary
  boost::python::dict m_dict;

  // test function to set the dictionary
  void test_set_dict();

  // prints the dictionary
  void printImageDict();

  // Dictionary getter - returns Pyobject because of the VTK Parser
  PyObject* getDict(){return (PyObject*)this->m_dict.ptr();}

  // Dictionary setter
  void setDict(PyObject *dd);

};


Thanks 

Kit

Okay, I managed this myself by cutting the extracted outline of the 
input image with the viewing plane (using vtkCutter).

Thanks,

I saw Bryan Conrad provided us a practical example on VTK animation (https://itk.org/Wiki/VTK/Examples/Python/Animation?). Now, I'd like to refer this example to animate objects (e.g. sphere or cone) under VTK-Web framework (e.g. vtk_web_cone.py). As far as I know, "TimerEvent" is used as a timer to trigger an event repeatedly, and this timer is bound to renderWindowInteractor by AddObserver. However, in vtk_web_cone.py, it seems that web server is waiting after the renderWindow is set as an active object. How can I start the timer? How to integrate the example into vtk_web_cone.py? Any suggestions are welcomed. Thanks in advance?.



Regards,


Zhuangming Shen

Subject: [vtkusers] Map StructuredGrid CellData onto a vtkPlaneWidget
Message-ID: <CAFuWFr+1FEfnQ9ySJJ_DR3wG+zBZD6t6zggbOV7+XbRhGmM+Og@mail.gmail.com>

Hi everybody, maybe this is a trivial question, but I don't know how to
select a StructuredGrid's cell data (insead of its points dada) in order to
map these values  onto a vtkPlaneWidget. I have modified the
ProbingWithPlaneWidget.py script in order to  test this feature. I build a
StructuredGrid with 12 points and only two cells, then I set the CellData
(two values which are correctly rendered as two colors by  the
StructuredGrid's mapper). If I build point data for the 12 points the probe
works fine, but if I remove the pointdata code and try to use the celldata
one, the probe is shown as white, with no color associated to the cell data.
Thanks in advance for any help.

Subject: [vtkusers] vtkWindowToImageFilter on Mac OsX gives incorrect output.
Message-ID: <1470147874457-5739464.post@n5.nabble.com>

All--

I'm having trouble running this example [1] from the Wiki on Mac OsX.  If I
set the magnification to 1, I get the expected output, as shown in the
example.  However, if I leave the magnification at 3 (as in the example), I
get an odd tessellation of the expected output (attached).  Has anyone run
into this issue before?

1.  I'm using the c++ version from the Wiki, unmodified.
2.  My version of OsX is 10.11.4
3.  I'm using the (just updated) development branch of VTK.

The same code behaves as expected on Ubuntu 14.04.

Best, and thanks very much in advance,

--Davis

------------------------------

Important Dates:
February 16, 2016: *Submissions open*
August 15, 2016: *Submissions deadline*
September 1, 2016: *Notifications sent*
------------------------------

*A new format for 2016!*

SC16?s Visualization and Data Analytics Showcase Program provides a forum
for the year?s most instrumental movies in HPC. This year, there will be
both a live display throughout the conference so that attendees can
experience and enjoy the latest in science and engineering HPC results
expressed through state-of-the-art visualization technologies, and a
session at SC16 dedicated to the best of the submissions.

Selected entries will be displayed live in a museum/art gallery format and
six finalists will compete for the Best Visualization Award, with each
finalist presenting his or her movie in a 15-minute presentation.

Movies are judged based on how their movie illuminates science, by the
quality of the movie, and for innovations in the process used for creating
the movie.

The six finalist submissions will appear as short papers on the SC16
webpage and archive.

*Review and selection process:*

Submissions need to include a movie (up to 250MB in size) and a short paper
(up to 4 pages including references). The short paper should describe the
scientific story conveyed by the movie, how the visualization helps
scientific discovery, and the ?state-of-the-practice? information (
ieeevis.org)information behind making the movie.

Each submission will be peer reviewed by the Visualization and Data
Analytics Showcase Committee. Criteria for review include:

   - How effective is the visual communication of the data?
   - How relevant to the HPC community is the visualization?
   - What is the impact of the science story and how well is it told?
   - What visualization techniques were necessary to create the movie?

Finally, submissions should support SC16?s overall theme ?HPC matters.?

Call for Participation: ISAV 2016
=========================

ISAV2016: In Situ Infrastructures for Enabling Extreme-Scale Analysis
and Visualization

In cooperation with SIGHPC and held in conjunction with SC16: The
International Conference on High Performance Computing, Networking,
Storage and Analysis, Salt Lake City, Utah, U.S.A.

Full-day Sunday November 13th, 2016

ISAV 2016 Web Site: http://vis.lbl.gov/Events/ISAV-2016/

Workshop Theme
------------------------

The considerable interest in the HPC community regarding in situ
analysis and visualization is  due to several factors. First is an I/O
cost savings, where data is analyzed/visualized while  being
generated, without first storing to a file system. Second is the
potential for increased  accuracy, where fine temporal sampling of
transient analysis might expose some complex behavior missed in coarse
temporal sampling. Third is the ability to use all available
resources, CPU?s and accelerators, in the computation of analysis
products.

The workshop brings together researchers, developers and practitioners
from industry, academia, and government laboratories developing,
applying, and deploying in situ methods in extreme-scale, high
performance computing. The goal is to present research findings,
lessons learned, and insights related to developing and applying in
situ methods and infrastructure across a range of science and
engineering applications in HPC environments; to discuss topics like
opportunities presented by new architectures, existing infrastructure
needs, requirements, and gaps, and experiences to foster and enable in
situ analysis and visualization; to serve as a ?center of gravity? for
researchers, practitioners, and users/consumers of in situ methods and
infrastructure in the HPC space.

Participation/Call for Papers and Oral Presentations
---------------------------------------------------------------------

We invite two types of submissions to ISAV 2016: (1) short, 4-page
papers that present research results, that identify opportunities or
challenges, and that present case studies/best practices for in situ
methods/infrastructure in the areas of data management, analysis and
visualization; (2) lightning presentation submission, consisting of a
1- or 2-page submission, for a brief oral presentation at the
workshop. Short papers will appear in the workshop proceedings and
will be invited to give an oral presentation of 15 to 20 minutes;
lightning round submissions that are invited to present at the
workshop will have author names and titles included as part of the
proceedings. Submissions of both types are welcome that fall within
one or more areas of interest, as follows:

Areas of interest for ISAV, include, but are not limited to:

In situ infrastructures
        * Current Systems: production quality, research prototypes
        * Opportunities
        * Gaps

System resources, hardware, and emerging architectures
        * Enabling Hardware
        * Hardware and architectures that provide opportunities for In situ

        * Significantly reduce the data size
        * Flexibility for post-processing exploration

Review Process
----------------------

All submissions will undergo a peer-review process consisting of three
reviews by experts in the field, and evaluated according to relevance
to the workshop theme, technical soundness, creativity, originality,
and impactfulness of method/results. Lightning round submissions will
be evaluated primarily for relevance to the workshop.

Submission Process
----------------------------

Authors are invited to submit papers of at most 4 pages in PDF format,
excluding references, and lightning presentations of at most 2 pages
in PDF format, excluding references. Papers should be formatted in the
ACM Proceedings Style (templates available at
https://www.acm.org/publications/proceedings-template) and submitted
via EasyChair (https://easychair.org/conferences/?conf=isav2016). No
changes to the margins, spacing, or font sizes as specified by the
style file are allowed.

Papers must be self-contained and provide the technical substance
required for the program committee to evaluate their contributions.
Submitted papers must be original work that has not appeared in and is
not under consideration for another conference or a journal. See the
ACM Prior Publication Policy for more details. Papers can be submitted
at https://easychair.org/conferences/?conf=isav2016.

---------------------------------------------------------------------------

All paper submissions that receive favorable reviews will be included
as part of the workshop proceedings, which will be published through
SIGHPC along with other SC16 workshop proceedings in the ACM Digital
Library and IEEE Xplore. Lightning round submissions will not be
included as part of the proceedings.

Subject to the constraints of workshop length, some subset of the
accepted publications will be invited to give a brief oral
presentation at the workshop. The exact number of such presentations
and their length will be determined after the review process has been
completed.

You have several options, but the simple one is to add a new rpc method on
the server side that will move to the next "step", and then on the client
side you can call that method at a given interval and asking for a render
right after it.

## Server

    @exportRpc("next.step")
    def next(self):
       # Do your stuff for animation
       pass

## Client

setInterval( function() {
   connection.session.call('next.step')
       .then(function() {
           viewport.render()
       });
}, 1000)

Subject: [vtkusers] Map StructuredGrid CellData onto a vtkPlaneWidget
Message-ID: <CAFuWFrKhWy_rwr6N_DQ6mQyXOc6YmyjmbWmtjEBLTuwOKh2EfQ@mail.gmail.com>

Hi everybody, I  have found how  to enable the  visualization of CellData
attributes mapped from a StructuredGrid to a vtkPlaneWidget. When I use
CellData instead of PointData in the StructuredGrid, these are treated as
FieldData and no longer as PointData. In this case, it is necessary to add
the following lines:

contourMapper.SetScalarModeToUsePointFieldData()
contourMapper.SelectColorArray("CellData")

where contourMapper is the vtkPolyDataMapper used to represent the plane
used as a probe. The name "CellData" is the one I had specified for the
CellData before passing it to the StructuredGrids.

I hope this may help.

  Thank  you

Subject: [vtkusers] Activiz.Net System.AccessViolationException updating
	pipeline
Message-ID: <CAD2gs8J81nDsotZMjo+GbO6f6q4GfoYHN7tw164h8V4L3bqUuw@mail.gmail.com>

Hi,
I'm using Activiz.Net x64 5.8 from the nuget package.  We are looking to
replace WPF graphics with VTK.  What we are trying to do as a starting
point is convert some WPF MeshGeometry3D objects into vtkPolyData and
display them.  This is working fine and we could see and interact with the
models.

The only problem was that the models looked faceted (WPF calculated the
normals automatically and VTK did not).  We went back to add in the
vtkPolyDataNormals filter, but are consistently receiving
System.AccessVioloationExceptions when executing the pipeline.  I have put
together the following code snippet to demonstrate the problem.  If called
twice (with the same data), the second time results in the exception being
thrown on the normal.Update() call.

vtkPoints points = vtkPoints.New();
vtkCellArray polys = vtkCellArray.New();
... populate points and polys ...

vtkPolyData polyData = vtkPolyData.New();
polyData.SetPoints(points);
polyData.SetPolys(polys);
vtkPolyDataNormals normal = vtkPolyDataNormals.New();
normal.SetInput(polyData);
normal.Update();

Any ideas?

Could this behavior be from the way that we convert the MeshGeometry3D to
vtkPolyData?

                        MeshGeometry3D mesh = ...

                        vtkPoints points = vtkPoints.New();
                        points.SetNumberOfPoints(mesh.Positions.Count);
                        vtkCellArray polys = vtkCellArray.New();
                        polys.SetNumberOfCells(mesh.TriangleIndices.Count /
3);

                        for (int i = 0; i < mesh.Positions.Count; i++)
                        {
                            points.InsertPoint(i, mesh.Positions[i].X,
mesh.Positions[i].Y, mesh.Positions[i].Z);
                        }
                        for (int i = 0; i < mesh.TriangleIndices.Count; i++)
                        {
                            vtkIdList trianglePoints = vtkIdList.New();
                            trianglePoints.SetNumberOfIds(3);
                            trianglePoints.InsertId(0,
mesh.TriangleIndices[i++]);
                            trianglePoints.InsertId(1,
mesh.TriangleIndices[i++]);
                            trianglePoints.InsertId(2,

Things just fail to move, silently.

As far as I'm aware, the only reason that VTK hasn't yet switched to a 64-bit MTime everywhere is that there would be backwards compatibility problems (GetMTime is a virtual method that is overridden in many subclasses).

I found another post where someone had a slightly similar problem and said removing and re-adding actors fixed the problem, which we also seem to see.....

The VTK pipeline uses the difference between timestamps to as an indicator for when to undertake certain actions.? So it is likely that problems only arise when this "difference" between two crucial timestamps exceeds the 32-bit limit.? That's why re-adding actors might fix the problem.
?
Also, why the runtime hit on a 64 bit build?.

What are you referring to? (I rarely use Windows, and when I do, I use 32-bit builds).

And to add (so that others searching the list will find it) anyone doing interventional medical imaging with VTK on Windows would be best advised to move the time variable to 64 bits, or you will have animation/ rendering problems.

Thanks

Subject: [vtkusers] C++ 11 compiler issues with Makefile generate using cmake
Message-ID: <CAJk8dSBQH_m8M7hs0fOEJx7oyRSQhWrnj+VpJjP3iDH3WCaCMQ@mail.gmail.com>

Hi,
In my C++ code I am initialising my data members in the header file
(example below)

class foo{
public:
 int myInt =0;
....
}

When I create the Makefile using cmake, and try to compile the compiler
trows an error that

 error: ISO C++ forbids initialization of member ?myInt?

I am using the "-std=c++0x" flag in my CMakeLists.txt file.

This is a standard feature and I am puzzled why the compiler is complaining
with the CMake generate Makefile.

Any expert comments?

Thanks,
Chiranjib

Subject: [vtkusers] Performance issues with triangle strips
Message-ID: <56feac72-7557-d42c-664e-68a4d7d7dcce@gmail.com>

Hello,

I am testing efficiency of triangle strips in visualization of large 
digital elevation models. Initial tests show signifficant improvements 
in memory usage, but also some performance issues: it seems that for 
example the vtkContourFilter performs _much_ worse when using strips.

I am running VTK7 with OpenGL2 backend on Ubuntu. For an example model 
with 46e6 triangles, I tested two versions of the code (I use Java 
wrappings):

                 grid = vtkPolyData();
                 grid.SetPoints(nodes);
                 grid.SetPolys(elems);

or
         [...]
                 grid.SetStrips(elems);

In the first scenario computing the contours took 13s, in the second - 
182s. I also used vtkStripper to actually compute some longer strips. 
For 50e3 computed strips the contour filter took 34s to update. Much 
better, but still worse than when using individual triangles.

So my questions are
  - is there something I can do to improve the contouring speed? (is it 
parallelizable in current VTK version, for example?)
  - are there any other known performance issues when using triangle 
strips in filters?

Thanks a lot!

Hi everbody,

How can I cut an object *without* closing the cut surface?
Can I deactivate the fill area in the class vtkClipClosedSurface?

Hi Chiranjib,

It could be one of several things.  First I would run make VERBOSE=1 to see
if the -std=c++0x is getting into the compile command correctly.  If it is,
then I would check if your compiler supports that feature.  Especially when
using the older compiler versions (the ones that use c++0x rather than
c++11) some language features may not be supported.

HTH,
Shawn

Also, adding the C++11 flags directly in the CMakeLists is not really the
recommended way to tell CMake to use C++11.  See these links (help pages
for the CMake variables you probably want) for the recommended way to do it
[1][2].

What are you using it for? If you're compiling on your own anyways,
using master could work if the code using VTK is VTK 7-ready (though if
it requires VTK 5, I suspect that's a long shot).

Sorry, I mistyped something and the email has been sent.

I'm new to VTK and on the rush to develop mock-up rendering a z = f( x, y )
3D surface using the VTK in a Qt main-window.

The goal of the mock-up is to test the load for large data such as, for
example, 32000x32000 discretization of the x and y axes.

I made a QMainWidow using a QVTKWidget and displaying a sphere (taken from
the Examples section).

I understood the general pipeline layout (similar to ITK) but I don't know
which VTK classes I should use/derive to modelize my z = f( x, y ) function
and render it.

Should I :

   - derive from vtkPolyDataAlgorithm and implement a point generation
   algorithm ;
   - fill in some vtkImageData ;
   - implement some filter taking grid data ;
   - other?

Basically, the user input the size (e.g. 32000), the software generates and
render the data.

As an option, I would like to add some controls to dynamically
increase/decrease the size parameter.

In a second step, we would like to test some adaptative rendering
algorithms the fast render the large number of vertices. Does VTK provide
such algorithms? How could I implement and insert one into the VTK pipeline
?

Hi St?phane,

The class that generates a z=f(x,y) surface is the vtkWarpScalar class.
Basic usage is as follows:
1) create a 2D image where the pixel value is the elevation (i.e. the z
value)
2) turn this into a polydata with vtkImageDataGeometryFilter
3) use vtkWarpScalar to set the "z" value of each point to the pixel value

Subject: [vtkusers] Find subset of connectivity table: better solution than
 brute force?
Message-ID: <1470247127811-5739489.post@n5.nabble.com>

Dear all, 

I am trying to find a way to highlight the facets corresponding to a set of
selected vertices taken on a facet/vertex shape model. 
Those facets therefore form a subset of the full shape model.

To do so, I was thinking of creating a VtkPolyData representing the
connectivity of the selected facets, so as to get the subset of the full
shape model.

I have access to the full shape's connectivity table (vertices coordinates
and facets definition with the vertices ids) and to the ids of the selected
vertices.

An intuitive (also know as brute-force) way to reconstruct the subset of the
connectivity table could be to search the connectivity table of the full
shape model,
to see which facets are completely included by the selected vertices blob.  

"completely included" meaning that the three vertices of the said facet can
be found among the selected vertices' ids.

Before delving into this, I was wondering if any of you had heard of a more
elegant, built-in solution enabling one to reconstruct this connectivity
table.

Many thanks, 
Ben

Subject: [vtkusers] Qt-based VTK app shows black image content if VTK is
 linked statically
Message-ID: <7649f6f5be29b946b01894509edb2463@srv19.sysproserver.de>

Hi list,

recently, I have been working on a Qt application (using VTK 
functionality in the main .exe and a bunch of underlying DLLs).

If VTK is built dynamically, the application behaves as expected.

However, if VTK is built statically (and - obviously - the application 
and underlying DLLs are then built using the static libraries of VTK), 
some content (vtkImageSlice) is missing in the render window, i.e. does 
not appear at all. Other parts (e.g. vtkPolyData) are shown correctly.

Anyone knows how to fix this? If possible, I would like to do static 
linking of VTK.

Thanks,

     sophonet

I can confirm that some issues occur when using VTK static as well (VTK stable 7.0.0).
I could not look further into the issue, but my application crashed instead of just black window, and I just rolled back to dynamic build.

Appreciate any details on this.

Hello,

I am trying to install VTK, but when I configure VTK in CMake, I get the
following error:

FAT32G is the name of the disk I am trying to install VTK on, and ITKstuffs
is the name of the folder I put all my ITK- and VTK-related things in. I am
not sure what is wrong with the VTK code that is causing this error. Below
is the code in PoissonReconstruction.remote.cmake, vtkAddon.remote.cmake,
and vtkDICOM.remote.cmake:

Hi,


I'm trying to link VTK and for some reason vtk is not finding some of the libraries, and when I search for it in the lib folder I did not find these libraries.

I specified the vtk path in the makefile, I'm not sure what I'm missing.

These are the libraries


 cannot find -lvtkRenderingParallel-6.1

cannot find -lvtkzlib-6.1

cannot find -lvtkFiltersParallelStatistics-6.1

cannot find -lvtkWrappingTools-6.1


thanks.

Hi David,

thanks for your fast reply, but I would just like on the intersection
between Plane and Polydata no polygons.
With GenerateFacesOff() the output will have all without polys.

vtkClipClosedSurface clip = new vtkClipClosedSurface();
clip.SetClippingPlanes(planeCollection);
clip.GenerateOutlineOn();
clip.AddInputData(polydata);
// clip.GenerateFacesOff();

Other suggestion?

How about use vtkCutter with a vtkPlane as the cut function?

See
http://www.vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/VisualizationAlgorithms/Python/ClipCow.py
for an example of it in use.

Hello there, 

I ended up using vtkPolyData::GetPointCells (vtkIdType ptId, vtkIdList
*cellIds) to find which cells the vertex identified by ptId belongs to.

In the context of my code, this method returns cell IDs of all cells
containing at least one selected point, as opposed to my initial plan to get
cells containing exactly three selected points. This solution suits me fine
though.

Hello,

I have already fixed the error in configuring VTK. It seems that building
VTK on a separate disk is what caused the error for some reason. It worked
fine after I re-downloaded VTK and kept it on my desktop when I configured
it.

However, when I try to link ITK and VTK together, I get an error message
when I configure ITK with the box for "Module_ItkVtkGlue". The message
states:

I could not find any file named VTKTargets.cmake or vtkModuleAPI.cmake. Are
these files I have to add myself? Any help would be greatly appreciated.


Thanks in advance.

Thanks. I wonder if it could be a cmake option to allow for some backwards compatibility where needed.

I think this happened because I changed the CMakeCache.txt

I changed the following parameters

BUILD_SHARED_LIBS:BOOL=OFF

VTK_USE_SYSTEM_ZLIB:BOOL=ON


I tried changing that back to its original value but when I try to build it using make I get the following error


/usr/bin/ld: CMakeFiles/vtkRenderingOpenGL.dir/vtkXOpenGLRenderWindow.cxx.o(.text+0x6ef0): sibling call optimization to `std::basic_stringbuf<char, std::char_traits<char>, std::allocator<char> >::~basic_stringbuf()' does not allow automatic multiple TOCs; recompile with -mminimal-toc or -fno-optimize-sibling-calls, or make `std::basic_stringbuf<char, std::char_traits<char>, std::allocator<char> >::~basic_stringbuf()' extern

Hi,


I'm trying to link VTK and for some reason vtk is not finding some of the libraries, and when I search for it in the lib folder I did not find these libraries.

I specified the vtk path in the makefile, I'm not sure what I'm missing.

These are the libraries


 cannot find -lvtkRenderingParallel-6.1

cannot find -lvtkzlib-6.1

cannot find -lvtkFiltersParallelStatistics-6.1

cannot find -lvtkWrappingTools-6.1


thanks.

Hi,

Usually when you change something major in VTK's build (such as
BUILD_SHARED_LIBS), you need to delete the build tree completely to keep
the leftovers from the old build from polluting the new one.  That is
probably what happened the first time too.  I don't know if
VTK_USE_SYSTEM_zlib is big enough to cause this... And did you rerun CMake
after you edited the cache?

HTH,
Shawn

After I changed it back to the original values

I did
 cmake
make clean
make

but I'm still getting the same error:
/usr/bin/ld: CMakeFiles/vtkRenderingOpenGL.dir/vtkXOpenGLRenderWindow.cxx.o(.text+0x6ef0): sibling call optimization to `std::basic_stringbuf<char, std::char_traits<char>, std::allocator<char> >::~basic_stringbuf()' does not allow automatic multiple TOCs; recompile with -mminimal-toc or -fno-optimize-sibling-calls, or make `std::basic_stringbuf<char, std::char_traits<char>, std::allocator<char> >::~basic_stringbuf()' extern

make[2]: *** [lib/libvtkRenderingOpenGL-6.1.so.1] Error 1

I'm trying to understand what causing the error, but no luck. Any idea on what might be the problem?

Two points.

1) Since you reran CMake before running make clean, the Makefile was
rewritten to remove the output of the new build rather than the old build.
So things from the old build that would have been removed were still
present.
2) CMake doesn't fully support make clean.  It works sometimes, but don't
depend on it... depending on what you are changing it can fail with really
strange errors.  It is safest to delete the entire build directory and
re-create it.

HTH,
Shawn

Two points.

1) Since you reran CMake before running make clean, the Makefile was rewritten to remove the output of the new build rather than the old build.  So things from the old build that would have been removed were still present.
2) CMake doesn't fully support make clean.  It works sometimes, but don't depend on it... depending on what you are changing it can fail with really strange errors.  It is safest to delete the entire build directory and re-create it.

Hi,

Usually when you change something major in VTK's build (such as BUILD_SHARED_LIBS), you need to delete the build tree completely to keep the leftovers from the old build from polluting the new one.  That is probably what happened the first time too.  I don't know if VTK_USE_SYSTEM_zlib is big enough to cause this... And did you rerun CMake after you edited the cache?

HTH,
Shawn

Hi,


I'm trying to link VTK and for some reason vtk is not finding some of the libraries, and when I search for it in the lib folder I did not find these libraries.

I specified the vtk path in the makefile, I'm not sure what I'm missing.

These are the libraries


 cannot find -lvtkRenderingParallel-6.1

cannot find -lvtkzlib-6.1

cannot find -lvtkFiltersParallelStatistics-6.1

cannot find -lvtkWrappingTools-6.1


thanks.

I forgot to mention that I'm building VTK on an HPC system.
And I read somewhere that building VTK "properly" for an HPC system can be tricky because of the lack of OpenGL

any suggestions?

Subject: [vtkusers] Setting vtkCamera to custom modelview & volume rendering
Message-ID: <4fac07d9-8772-adab-79bf-027f0a9d2f00@gmail.com>

Hi,

I need to setup the camera to an arbitrary modelview matrix I have in 
memory.  I managed to get some code working such that 
GetModelViewTransformMatrix() returns the modelview I have/want. However 
the volume rendering is sometimes blank, and I don't understand why 
because the volume is in front of the camera.  I managed to boil down 
the problem to the following code below. camera1 and camera2 have the 
same modelview transform, however the rendering look very different 
(I've attached a screen shot) - though not blank it's a lot dimmer.

The code is loosely based on: 
http://www.vtk.org/Wiki/VTK/Examples/Cxx/VolumeRendering/SmartVolumeMapper

I'm using VTK 7.0

I was just doing a very similar thing and noticed that light positions are
only updated with the set origin, focal point and up. I ended up computing
those for my intended matrix and lighting then worked as expected.

Thanks,

The light positions were indeed different, but making them the same 
didn't fix it for me.  Perhaps my fix is wrong?

void assertArrayEquals(const double * a, const double * b, size_t elements)
{
     for (size_t i = 0; i < elements; ++i)
     {
         assert(a[i] - b[i] <= std::numeric_limits<double>::epsilon());
     }
}

     //previous int main() code ...

     //setting lights before first call to Render() crashes program, 
also describedh http://www.vtk.org/Wiki/VTK/Examples/Cxx/Lighting/Light

     renderWindow->Render();

     renderer2->RemoveAllLights();
     vtkSmartPointer<vtkLight> newLight = vtkSmartPointer<vtkLight>::New();
     newLight->SetPosition(0, 0, 1000);
     renderer2->AddLight(newLight);

     //assert lighting is the same
     vtkSmartPointer<vtkLightCollection> lightCollection1 = 
renderer1->GetLights();
     vtkSmartPointer<vtkLightCollection> lightCollection2 = 
renderer2->GetLights();
     assert(lightCollection1->GetNumberOfItems() == 
lightCollection2->GetNumberOfItems());
     lightCollection1->InitTraversal();
     lightCollection2->InitTraversal();
     vtkSmartPointer<vtkLight> light1 = lightCollection1->GetNextItem();
     vtkSmartPointer<vtkLight> light2 = lightCollection2->GetNextItem();
     assertArrayEquals(light1->GetPosition(), light2->GetPosition(), 3);
     assertArrayEquals(light1->GetTransformedPosition(), 
light2->GetTransformedPosition(), 3);
     assertArrayEquals(light1->GetFocalPoint(), light2->GetFocalPoint(), 3);
     assertArrayEquals(light1->GetTransformedFocalPoint(), 
light1->GetTransformedFocalPoint(), 3);
     assertArrayEquals(light1->GetAmbientColor(), 
light2->GetAmbientColor(), 3);
     assertArrayEquals(light1->GetSpecularColor(), 
light2->GetSpecularColor(), 3);
     assertArrayEquals(light1->GetDiffuseColor(), 
light2->GetDiffuseColor(), 3);

     renderWindow->Render();

     renderWindowInteractor->Start();

Hi Sophonet and Enzo,

is it possible you made other changes besides switching VTK from DLLs to
static libraries? Perhaps your application was using a different version of
VTK DLLs than you thought etc.

If that is not the case, can you point to an example which exhibits the
problem?

Regards,
D?enan

Hi,

great that this is beine picked up. No, absolutely no changes besides 
switching from dynamic to static. The revision was exactly the same, the 
CMake flags as well.

Again, some content (vtkPolyData) was shown, but other content (in my 
case results of vtkImageReslice) was not. If you guys have already a 
clue about what might be the cause, please go ahead, otherwise, I will 
try to set up a minimal example in the next days/weeks, and if I find 
something, I will file a merge request.

Cheers,

      Sophonet

Hello!

I don't now if this helps, but errors like '.AccessViolations' are mostly
(at least for activiz.net) the result of missing references to VTK-objects
(cause the .net garbage collector may clean up objects that are still used
by VTK).

Subject: [vtkusers] std::string from vtkStringArray seg faults
Message-ID: <CANFuGOpkgMY5MemXAm90iEaKgOniJFt3rnZXgcAbnvBHiYsxYQ@mail.gmail.com>

The following code causes a seg fault

string s = sourceArray->GetValue(0);
cout << s << endl;

this is also a seg fault

string * s = &sourceArray->GetValue(0);
cout << *s << endl;

but

vtkStdString * s = sourceArray->GetValue(0);
cout << *s << endl;

does not.

What am I miss understanding about getting strings out of a string array?

Subject: [vtkusers] Why the baggage in vtkInteractorStyle?
Message-ID: <CAE-7VJnwA8NkPaPq7y-SrdEb3qBk6zbWu11X+zGAn6Vgop+xRA@mail.gmail.com>

Hi all,

This is a bit of a general question about the interactor style system in
VTK.

Why does vtkInteractorStyle, which is described as the superclass of all
interactor styles, have things functions like Dolly, Pan, Zoom et.c.? And
why does it have keypress behaviors at all (e.g. 'j', 't', 'c', 'a', ...)?


If it's supposed to be a general base class for interactor styles, why
should it make assumptions like this about the camera movements the
subclasser want to provide, and assumptions about keybindings?

I'm looking for a base class to use, which is not making any such
assumptions, since I want to provide a completely custom behavior, without
having to guard myself against unwanted behavior coming from the base class.

I've looked at, and even used vtkInteractorStyleUser, for this purpose
(even if it's described as something mostly for the scripting languages),
but I'm just wondering about the VTK design, why it was made this way?

Thanks in advance,
Elvis

I think you need to subclass vtkoutputWindow and override whatever method
to make it do what you need.

I am trying to build a library project in Android Studio, or using Gradle command-line,
based on VTK 7.0.0 and OpenCV 3.1.0

I built the VTK libraries for Android arm64-v8a platform as static libraries (.a files)
and then included all of them in the build.gradle for my own library project.

For example, my build.gradle includes :

apply plugin: 'com.android.model.native'
def commonBase = "${projectDir}/../../../common"
model {
    repositories {
        libs(PrebuiltLibraries) {
// (more vtk libraries here)
            vtkCommonColor {
                headers.srcDir "${commonBase}/thirdparty/vtk-7.0/include"
                binaries.withType(StaticLibraryBinary) {
                    staticLibraryFile = file("${commonBase}/thirdparty/vtk-7.0/lib/arm64-v8a/libvtkCommonColor-7.0.a")
                }
            }
            vtkCommonCore {
                headers.srcDir "${commonBase}/thirdparty/vtk-7.0/include"
                binaries.withType(StaticLibraryBinary) {
                    staticLibraryFile = file("${commonBase}/thirdparty/vtk-7.0/lib/arm64-v8a/libvtkCommonCore-7.0.a")
                }
            }
// more vtk libraries here
}
}
...
    android {
        compileSdkVersion 21
        buildToolsVersion "23.0.2"

        defaultConfig {
            minSdkVersion.apiLevel 19
            targetSdkVersion.apiLevel 19
        }

        sources {
            main {
                jni {
                    dependencies {
// more vtk libraries here
                        library "vtkCommonColor" linkage "static"
                        library "vtkCommonCore" linkage "static"
// more vtk libraries here

...

But even with all of the VTK libraries included, I still get a lot of "undefined reference"
errors for VTK classes/methods which are included in the VTK libraries,
when building (linking) my project via

$ ./gradlew clean buil..

I saw there  were some old threads discussing similar Android issues,
but didn't see much recently as far as any solutions to using Gradle.
Since Google is recommending that Android developers move to
Android Studio and Gradle, and has been adding more NDK / native support,
this seems to be the preferred way of doing things, instead of using
.mk files or CMake

Any other sugestions ?

Also, one other question.

I am trying to modify VTK-7.0.0/Examples/Android/JavaVTK/jni/main.cxx

to make use of #include "vtkOBJReader.h"

but I am getting fatal error: vtkOBJReader.h: No such file or directory

even though the file is present in


IO/Geometry/vtkOBJReader.h


and


build/CMakeExternals/Install/vtk-android/include/vtk-7.0/vtkOBJReader.h


Is there an extra step that I need to do so that the build can find it ?


Thanks in advance for any tips.

Oh, actually I think I fixed the second issue by adding vtkIOGeometry
to VTK-7.0.0/Examples/Android/JavaVTK/CMakeLists.txt
in this section

find_package(VTK COMPONENTS
  vtkIOGeometry
  vtkInteractionStyle
  vtkRenderingOpenGL2
  vtkRenderingFreeType
)

Message-ID: <CAE-7VJmY17xqr4BQEYAV8jB4jCuHHjqGX48HN_j-2YBNLo3zDw@mail.gmail.com>

Hi all, (mostly David Gobbi :))

In a previous thread, you kindly outlined your way of handing interaction
in PyQt applications without making use of the VTK interactor/interactor
style system at all.

My question now is whether you do something similar when working from C++?
The reason I'm asking is that I'm in the process of porting an application
under development from PyQt to Qt/C++, and I'm weighing the pros and cons
of making use of VTK interactor/interactor styles vs making my own "tool
system" for interaction.

If you do use a similar system when working from C++, I'm wondering whether
you make use of QVTKWidget, or if you have your own such class? Because
looking at QVTKWidget (which I currently make use of), it seems to force a
VTK interactor to be set on its rendering window (if one is not provided,
it will create one).

Thanks a lot in advance for any advice.

Elvis

Hi All,
I use VtkpropPicker for pick data. I saw that  a lot of use memory while
using tetra cell data. 
I took out of memory. Data is very big. Vtkcellpicker did not take out of
memory but pick process is a little slow. Do you have any idea whan I can
do?

Example Code;

   vtk.vtkPropPicker propPick = new vtk.vtkPropPicker();
   ....
   propPick.AddPickList(vv.VtkProp);
   propPick.PickFromListOn();

   pResult = propPick.Pick((double)X, (double)Y, 0,
InViewport.CurrentVtkRenderer); //this method using very memory.

Subject: [vtkusers] How to know the type of a vtk file
Message-ID: <2016080916360372731011@gmail.com>

Hi all,
I'm a newer to VTK. I know that there are two VTK file formats to save objects, one is the legacy format, another is  XML-based file format. For the XML-based format, different data types have different file extensions. For example, .vti for vtkImageData, .vtp for vtkPolyData, .vts for vtkStructuredGrid. However, for the legacy format, there is only one file extension (.vtk). My question is there a quick function in VTK to know the exact data type of a .vtk file?

Thanks,

Maogui Hu

I realize now that the docs are a little out of date, and that some of the
keyboard shortcuts I mention are now handled by vtkInteractorStyleSwitch.

But I'm still wondering why vtkInteractorStyle makes so many assumptions
about how a subclasser wishes to implement his/her style. I would have
expected a more "bare bone" base class.

I think it's really just for convenience / laziness. It's nice to be
able to use all the familiar keyboard shortcuts in all your simple
little test/example VTK apps without having to customize the
interactor style at all.

It's been that way for a long long time now, and changing it would
probably be somewhat controversial among some of the long time VTK
developers.

As with most answers to questions like this, it's just a consequence
of the organic growth VTK has undergone over time. It probably wasn't
really **designed** that way intentionally, it probably just sort of
happened that way, and since it works and there is a way to do what
you want (override, and implement everything yourself...) then nobody
has bothered with trying to impose a more sensible design on it after
the fact.


HTH,
David C.

Alright, thanks for clarifying! And sorry for the sort-of pointless
question. I guess I'm so used to the way the top base classes are designed
in e.g. Qt, not imposing any particular behavior.

Yes, if you need other modules that is the place to add them. Some modules
may not compile under Android as we have only tested some of them but
hopefully the ones you need work.

Thanks

You can use vtkDataSetReader::ReadOutputType() [1] to tell what type
of data set is in a .vtk file. This member function will return one of
VTK_POLY_DATA, VTK_STRUCTURED_POINTS, VTK_STRUCTURED_GRID,
VTK_RECTILINEAR_GRID, or VTK_UNSTRUCTURED_GRID if the data set can be
read. -1 indicates an error with the output type.

Yes, I've been doing this in Qt/C++ for a while now, in fact I'm pretty
sure that what I described previously was Qt/C++, and not the older PyQt
interaction that I used a decade ago.

If you do use a similar system when working from C++, I'm wondering whether

No, I don't use QVTKWidget.  Tying Qt and VTK together is tricky, and I
felt that I needed total control over the QT<->VTK connection which meant
writing my own class.  I wanted something minimal so that I'd be able to
fix problems quickly.

Ah, I see.

Because looking at QVTKWidget (which I currently make use of), it seems to
force a VTK interactor to be set on its rendering window (if one is not
provided, it will create one).

Alright, that makes sense then. I'll see how I'll proceed. Thanks for
sharing.

Hi all,

regarding this topic: In the meantime, I have found out that indeed, 
when using static VTK libraries, the image-related components (e.g. 
vtkImageResliceMapper) always retrieve invalid bounds / whole data 
extent from the input image data (0,-1,0,-1,0,-1) - and the 
corresponding content is black. When using dynamic VTK libraries, the 
information is correct, and the resliced image is shown as expected.

The only function which (indirectly) sets invalid image dimensions is 
PrepareForNewData(), which is called from vtkImageResliceMapper's 
Update().

Ideally, I would like to continue debugging and find out why, in case of 
static VTK libraries, the information is not correctly overwritten later 
in my case, but would appreciate any help, since the processing / 
updating mechanism during a Render() call are not clear to me.

Any hints or ideas?

Thanks,

     sophonet

D?enan,

I?m pretty sure I was using the correct libraries (VTK 7.0 static with Qt 5.7).

My current test case is heavily based on this VTK example, so I believe it will reproduce this buggy behaviour:
http://www.vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/GUI/Qt/FourPaneViewer/QtVTKRenderWindows.cxx <http://www.vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/GUI/Qt/FourPaneViewer/QtVTKRenderWindows.cxx>

I?m sorry I can?t look deeper into this issue, but I?m up to testing new future fixes and also sending additional information if necessary.


Thanks!

Hi Enzo,

I have a statically built VTK (6.3.0 and a recent git version), and
compiling that example produces an executable
<https://dl.dropboxusercontent.com/u/48665006/QtVTKRenderWindows.exe> which
loads an image and reslice views are shown. The example does not work
totally correctly - 2D and 3D views are not synchronized, fiddling with
options on the right can make reslice views disappear or crash the program,
blue slice is not initialized in the correct position etc. Here is a
screenshot:

Subject: [vtkusers] Memory management issues: how to track memory usage?
Message-ID: <1470769689625-5739607.post@n5.nabble.com>

Dear all, 
I am developing an application where face/vertex shape models are displayed
and interacted with. Using a rectangular box selection, the user can
highlight the selected region, apply a geometric transform to the selected
vertices and thus modify the original shape.

If VTK seems to have all the features I need to fully implement my specs, I
am however dealing with memory management issues which I have not been able
to fix yet.

Typically, opening a shape model and just leaving it there requires about
300MB of memory. Selecting a region adds another 150MB to the memory
consumption. I was hoping to see the memory going back to 300MB once the
selection window is closed (and the corresponding actors/polydata cleared),
but I am left with 350MB of memory usage. So something did not get cleared
as expected.

I understand that this very high level description of those RAM issues can
only get a very general answer at best. However, I was wondering if you knew
a debbugging method allowing one to track the memory used by a pointed
variable (variable pointed at by a vtkSmartPointer)?

Thanks, 
Ben

Indeed, I can reproduce this problem with VTK 7.0.0 (statically linked).

Is there any plan going forward, e.g. D?enan, have you planned on 
discussing with colleagues how to tackle this problem, or would you like 
Enzo or myself to file some kind of bug report? (If so, where is the 
best place)?

Thanks,


      Sophonet

I believe there's a VTK_DEBUG_LEAKS CMake variable you can set when
building VTK, which enables some memory tracking facilities. I'm afraid I
don't know more than that, as I haven't used it myself, but would be
interested in your findings as I've been meaning to try it out.

Someone else can probably give more info about this option (I'm on the bus
atm).

Hello! I use vtkScalarBarActor and vtkTextActor, they are not bright and
clear. I think it is a problem with all vtkActor2D. Below is the code and
the picture demonstrate the problem. Please, tell me how to solve the
problem.

        Java and VTK 7.0.

        vtkRenderWindowPanel mRenderWindowPanel1 = new
vtkRenderWindowPanel();
        mRenderWindowPanel1.GetRenderer().SetBackground(1, 1, 1);//White
        mRenderWindowPanel1.GetRenderer().ResetCamera();
        mRenderWindowPanel1.GetRenderWindow().PointSmoothingOn();
        mRenderWindowPanel1.GetRenderWindow().LineSmoothingOn();
        mRenderWindowPanel1.GetRenderWindow().PolygonSmoothingOn();
        mRenderWindowPanel1.setSize(jPanel1.getSize());
        jPanel1.add(mRenderWindowPanel1);

        vtkTextActor mActorTitle = new vtkTextActor();
        mActorTitle.GetTextProperty().SetFontFamily(4); //4-????? ?? ?????
        mActorTitle.GetTextProperty().SetFontFile("font.ttf");
        mActorTitle.GetTextProperty().SetFontSize(SizeTitle);
        try {
            mActorTitle.SetInput(new String(title.getBytes("UTF-8")));
        } catch (UnsupportedEncodingException ex) {
            Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null,
ex);
        }
        mActorTitle.SetDisplayPosition(5,
jPanel1.getSize().height-SizeTitle-6);
        mActorTitle.GetTextProperty().SetColor(0.0, 0.0, 0.0);
        mRenderWindowPanel1.GetRenderer().AddActor(mActorTitle);

Subject: [vtkusers] Small question about the camera parallel scale
Message-ID: <CAE-7VJkN+mJYXKN6ORdQ-R50oJ9oD=6y8dxYS=oDkpY7FMrQog@mail.gmail.com>

The docs for Get/SetParallelScale says:

"Set/Get the scaling used for a parallel projection, i.e. the height of the
viewport in world-coordinate distances."

But it seems that the parallel scale is actually twice the height of the
viewport in world-coordinate distances. E.g. if I want 1000.0 units in
world-coordinates to be visible in the vertical direction in the viewport,
I should set the parallel scale of the camera to 500.0.

Am I missing something? Or is it just that I don't know the terminology,
what does "height of the viewport" actually mean?

Thanks in advance,
Elvis

Hi Elvis,

Could it be that the height and width are probably measured from the 
focal point to the border (thus 500 units would result in a border to 
border height of 1000 units) ?

Cheers,

Andrea

Ah yes, this is probably what is meant with "viewport height" in the
documentation. I just wasn't aware of the terminology. Thanks.

I am not 100% sure of that, but I think it is likely so.

Subject: [vtkusers] Plotting flat surface using vtkChartXYZ and
	vtkPlotSurface
Message-ID: <CAPf=F6iio6b7mEKN1teFAhFy+cghT09wO+hqAswkrfb5t77=kw@mail.gmail.com>

Hi all,

I'm having a really though time plotting a flat surface (as in every point
from that surface has the same *z value*). I'm using the QVTKWidget in my
Qt 5.7 application. My idea is to show one or multiple signals which
represent how near one or multiple (up to 10) fingers come to the surface
of a device. So initially the surface plot is flat (since no fingers are
touching it). Whenever a finger comes near the surface, the device emits
the position of that finger (*x,y values*) along with a signal strength at
that position (*z value*). I'm really new to the whole chart and surface
plotting in VTK (I have used it with PCL) so I have no idea where to look
at (it took me quite some time to even build and integrate the VTK and the
surface plot in my Qt application...). Basically if I set all my points to
have the same *z value* the surface plot simply doesn't show. I think this
has something to do with the scaling of the chart and the fact that it
expects a range of values. Even if it's binary (that is only two values are
possible for each *z value*) the min and max have to be different. Setting
the min and max to a very small values (min: 0, max: 0.00001) doesn't help
at all since the chart scales to these values and I get a very noisy
surface plot. Currently my plot is static (though I intend to bind it to
near real time values if it works out) and I'm setting up the data as
follows:

void Q3DTouchPadSignalsFingersPlot::setupPlot() {

    int numPoints = 100;

    double inc = 9.424778 / (numPoints - 1);


    for (int i = 0; i < (int)numPoints; ++i) {

        vtkNew<vtkFloatArray> arr;

        this->surfaceData->AddColumn(arr.GetPointer());

    }


    this->surfaceData->SetNumberOfRows(numPoints);


    for (int i = 0; i < (int)numPoints; ++i) {

        double x = i*inc;


        //        double x = i;

        for (int j = 0; j < (int)numPoints; ++j) {

            double y = j*inc;

            //            double y = j;

            this->surfaceData->SetValue(i, j,

                                        sin(sqrt(x*x + y*y))/sqrt(x*x + y*y));

                                        // sin(sqrt(x*x + y*y)) |
sin(sqrt(x*x + y*y))/sqrt(x*x + y*y)

        }

    }


    this->plot->SetXRange(0, 9.424778);

    this->plot->SetYRange(0, 9.424778);

    this->plot->SetInputData(this->surfaceData.GetPointer());

}


This produces a quater of the function sin(sqrt(x*x + y*y))/sqrt(x*x + y*y)):


[image: Inline images 2]


If I change the setting of the data at the given location in the
surface to this->surfaceData->SetValue(i, j, 1) (that is I use a
constant)

the plot disappears:


[image: Inline images 1]


Any ideas how to fix this?


Kind regards,

Aleksandar

Subject: [vtkusers] Forward declaration of Foo enough for vtkNew<Foo>
	declaration?
Message-ID: <CAE-7VJnvBuz4S=_nzho-bcQQOcswFx+zoFkk=FFAhGJh8kyKfQ@mail.gmail.com>

Hi,

The overview at

    https://blog.kitware.com/a-tour-of-vtk-pointer-classes/

seems to suggest that forward declaration of a class Foo should be enough
to be able to declare a vtkNew<Foo> (e.g. see how vtkTable is used in the
code example under "Use of Classes").

But when I try e.g:

class vtkCompositeTransferFunctionItem;
...
vtkNew<vtkCompositeTransferFunctionItem> m_functionsItem;

I get

    error: invalid use of incomplete type ?class
vtkCompositeTransferFunctionItem?

Do I really need to include vtkCompositeTransferFunctionItem.h to declare a
vtkNew<vtkCompositeTransferFunctionItem> ?

Thanks,
Elvis

To show more of the context where I'm trying this:

#pragma once

#include "VTKWidget.h"

#include <QObject>
#include <Qt>

#include <vtkNew.h>

#include <vtkChartXY.h>
#include <vtkContextView.h>
#include <vtkCompositeControlPointsItem.h>
#include <vtkCompositeTransferFunctionItem.h>

class QWidget;

class vtkColorTransferFunction;
// Apparently I can't just forward declare these.
//class vtkChartXY;
//class vtkCompositeTransferFunctionItem;
//class vtkCompositeControlPointsItem;
//class vtkContextView;
class vtkPiecewiseFunction;

class CompositeTransferFunctionEditor : public VTKWidget
{
    Q_OBJECT

public:
    enum Mode {
        EditColor,
        EditOpacity
    };
    Q_ENUM(Mode)

public:
    CompositeTransferFunctionEditor(vtkColorTransferFunction *colorFunction,
                                    vtkPiecewiseFunction *opacityFunction,
                                    Mode mode = EditColor,
                                    QWidget *parent = 0,
                                    Qt::WindowFlags flags =
Qt::WindowFlags());

    void setColorFunction(vtkColorTransferFunction *colorFunction);
    void setOpacityFunction(vtkPiecewiseFunction *opacityFunction);

signals:
    void functionsModified();

private:
    void editColorPoint();

private:
    vtkNew<vtkCompositeTransferFunctionItem> m_functionsItem;
    vtkNew<vtkCompositeControlPointsItem> m_pointsItem;
    vtkNew<vtkChartXY> m_chart;
    vtkNew<vtkContextView> m_contextView;
};

I had hoped I would only have to forward declare the types used in the
instantiations of vtkNew here, not include the full headers.

Subject: [vtkusers] Utilities/Maintenance/WhatModulesVTK.py will not report
	vtkRenderingContextOpenGL
Message-ID: <CAE-7VJ=B0230uH1kjgKYmUp2BYHM8F+KVJDfZAO+5NKXrdKDcw@mail.gmail.com>

I make use of the very convenient script in

    Utilities/Maintenance/WhatModulesVTK.py

to calculate precisely the VTK modules I make use of, and I can pretty much
copy-paste the result to the find_package and target_link_libraries in my
CMakeLists.txt. So far the only manual touch-up I've had to do is change

    vtkRenderingOpenGL
    vtkRenderingVolumeOpenGL

to

    vtkRenderingOpenGL2
    vtkRenderingVolumeOpenGL2

since it seems the script cannot know that I'm using a VTK compiled with
the OpenGL2 backend.

However, now I've ran into another minor snag: I've begun using a
vtkContextView, so the script would report

    vtkRenderingContext2D

But it seems it will not report

    vtkRenderingContextOpenGL2

which it seems I also need, or the factories won't work (I think related in
some way to
http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Factories_now_require_defines ,
or perhaps to the splitting of the OpenGL backends).

Anyone know why the script won't report vtkRenderingContextOpenGL2 (or at
least vtkRenderingContextOpenGL, I'm fine with having to add the "2"
manually) ? Will I always have to add it manually?

It's so convenient to be able to just copy-paste whatever the script
outputs.

Thanks in advance,
Elvis

This sounds like the operating system is caching some memory. When a
process releases memory, often times the OS will keep some of it
marked as in-use to speed up future allocations. There may be
OS-specific methods to disable this behavior or force cached memory to
be freed, though I'm not sure.

Several vtkObject subclasses have a GetActualMemorySize() method.
These may be useful here.

VTK_DEBUG_LEAKS keeps track of vtkObjects that have been allocated but
not freed. When enabled in CMake, it will print a list of all leaked
vtkObjects when the process exits. This can be handy for identifying
missing calls to vtkObject::Delete(). There's also a static method
vtkDebugLeaks::PrintCurrentLeaks() which will print a list of all
vtkObjects currently in memory, which may be helpful to compare
before/after the selection to determine if the problem is an actual
leak or a caching issue.

This is correct. The vtkNew template does not require its parameter's
header to be included and forward declaration is sufficient. Look
through the VTK code and you'll see this pattern used in a lot of
headers.

What is the full error (with file path, line number, etc)? I wonder if
the moc'd header that Qt generates is trying to do something funky
here. Which line is it complaining about?

Hi Elvis,

The problem is this:  Declaring vtkNew<Foo> should be fine when Foo is
forward declared.  But when the vtkNew<Foo> is deleted in your destructor,
the vtkNew<Foo>'s destructor needs to call Foo->Delete().  So at that point
it needs the full definition of Foo.  In your example, if you declare your
class's destructor and implement it as {} (use the default) in an
implementation file where Foo's header is included this should work.  One
of my projects uses vtkNew this way.

HTH,
Shawn

Subject: [vtkusers] Error linking QVTK
Message-ID: <CAAq9_B5X=cdgXq5p8HvhB6aVqAkPjK0q49CkAos=fyDCsXNidw@mail.gmail.com>

Hi all,

I am having some trouble when I try to build a project that requires QVTK:

$ make
Linking CXX executable TBI_APP
/usr/bin/ld: cannot find -lQVTK
collect2: error: ld returned 1 exit status
CMakeFiles/TBI_APP.dir/build.make:660: recipe for target 'TBI_APP' failed
make[2]: *** [TBI_APP] Error 1
CMakeFiles/Makefile2:60: recipe for target 'CMakeFiles/TBI_APP.dir/all' failed
make[1]: *** [CMakeFiles/TBI_APP.dir/all] Error 2
Makefile:75: recipe for target 'all' failed
make: *** [all] Error 2

I configure the project with ccmake but I get this linking error and I
am not sure why. Maybe I am not configuring VTK right or something
like that, but any help or hint will be really appreciated.

Thanks!

Nico.

Might be a silly question, but did you build VTK with Qt support, i.e.,
with the VTK_Group_Qt option set to on?

Sorry for the terse error message, I should have pasted more.

But it looks like Shawn has guessed what my problem was.

Thanks Shawn, that was indeed the problem. Adding empty destructors did the
trick.

Hey Cory, thanks for your reply.

Yes, that option is activated, and I have VTK installed.

Also, something weird happens, when configuring with cmake, if I try
to change the version of `qmake` (to 5.7), it changes:

This is by default:
QT_QMAKE_EXECUTABLE              /usr/bin/qmake-qt4

I change to:
QT_QMAKE_EXECUTABLE              /home/user/Qt/5.7/bin/qmake

and it goes back automatically:
QT_QMAKE_EXECUTABLE              /usr/bin/qmake-qt4

You need to change the Qt version you want to fix the Qt configuration
problem. Look for the VTK_QT_VERSION and set it to 5 if you want to use Qt
5.7.

QT_QMAKE_EXECUTABLE isn't actually needed when you want Qt 5. Instead, you
need to set Qt5_DIR to something like

/home/user/Qt/5.7/lib/cmake/Qt5

The rest of the Qt5 settings should be set next time you configure. Then
you can delete all the QT* settings brought in when Qt 4 was found.

There's the VTK_QT_VERSION flag which you need to set to "5" in order to
get Qt5. QT_QMAKE_EXECUTABLE is always a Qt4 variable.

The edit will need to happen on the client.

With jQuery you will need to unbind those events on the mouse listener
container like follow:

$('.mouse-listener').unbind("DOMMouseScroll mousewheel");

You can add that line within the <script> tag after the viewport has been
created and bind to a DOM element.

Cory,

Yes, I've been meaning to look at this for ages, but there are a number of issues, I'll start a new thread on vtk-dev...

Subject: [vtkusers] Gouraud shading of a vtkStructuredGrid's boundary
Message-ID: <CAFuWFrKpJ_a4DK4hp4azzTYNc+XgJx382C1G6p_zYVaCtC_+tg@mail.gmail.com>

Hi everybody,
Is there  any way to visualize a StructuredGrid's boundary with Gouraud
shading?
When I use a very simple pipeline vtkStructuredGrid -> vtkDataSetMapper  ->
vtkActor I am able to visualize the closed boundary of the grid. The
polygons used in the rendering are triangles with a flat shading look.
If I wish to apply  a Gouraud shading to this boundary, should I extract
this closed surface as a vtkPolyData and then use vtkPolyDataNormals on it?
If this is the case, How can I extract the boundary? Should I use
vtkStructuredGridGeometryFilter to obtain six separate polydata's defining
the boundary and then append them using vtkAppendPolyData?

Thank you very much for your help

Hi Cory and Ben,

this is how I've configured VTK so far:

 Qt5Core_DIR
/home/user/Qt/5.7/gcc_64/lib/cmake/Qt5Core
 Qt5Gui_DIR
/home/user/Qt/5.7/gcc_64/lib/cmake/Qt5Gui
 Qt5Sql_DIR
/home/user/Qt/5.7/gcc_64/lib/cmake/Qt5Sql
 Qt5UiPlugin_DIR
/home/user/Qt/5.7/gcc_64/lib/cmake/Qt5UiPlugin
 Qt5Widgets_DIR
/home/user/Qt/5.7/gcc_64/lib/cmake/Qt5Widgets
 Qt5X11Extras_DIR
/home/user/Qt/5.7/gcc_64/lib/cmake/Qt5X11Extras
 Qt5_DIR                          /home/user/Qt/5.7/gcc_64/lib/cmake/Qt5
...
VTK_Group_Qt                     ON
...
VTK_QT_VERSION                   5

I guess this configuration follows your suggestions. So the problem
might be another. Where should I find QVTK?

Thanks

Nico,

That looks good. Could you provide details on how you are setting up the
link libraries for your project? Posting your CMake code is helpful.

Thanks,

Luca,

You are on the right track. vtkStructuredGridGeometryFilter should extract
just one polydata defining all the boundaries of your structured grid. In
the end, your pipeline should look like

vtkStructuredGrid -> vtkStructuredGridGeometryFilter -> vtkPolyDataNormals
-> vtkDataSetMapper -> vtkActor

HTH,
Cory

Nico,

I don't believe you need to add QVTK to your list of target libraries.
Try removing it.

All the libraries in your chosen VTK build will be added when you
include ${VTK_LIBRARIES} in your target_link_libraries.

Thanks,
Cory

Cory,

Yes, I had removed that before and that built well. I thought that was
something I needed, but apparently it isn't.

Thanks for the help!
Nico.

Nico,

I think that may have been needed in earlier versions of VTK as it
looks familiar, but it is no longer needed.

Glad it's working.

Hi Cory, thank you for your reply.

You are absolutely right! I have followed  your adviced and removed the
SetExtent() call to vtkStructuredGridGeometryFIlter (I had previously used
six of them to get the all the boundaries and then merged them with
vtkAppendPolyData) and I have magically obtained the complete boundary as
output with a single filter.
It worked really fine.
Thank you for your kind help!

Best regards,

   Luca

Subject: [vtkusers] Gouraud shading of a vtkStructuredGrid's boundary

Sorry Cory, I was mistaken and way too quick in replying. When I wrote the
last mail I was still observing the output from the six combined
vtkStructuredGridGeometryFilter's. Now I have tried one single filter
without providing any SetExtent call and the result I have is the
visualization of the StructuredGrid's points. No Boundary. How can I
instruct the filter to generate the Boundaries?

Thank you

Two things to try: 1) set the extent to the whole extent of your grid,
or 2) try using vtkDataSetSurfaceFilter instead of
vtkStructuredGridGeometryFilter.

Hi Cory, thank you for the quick reply.
I have tried setting the whole extent of the grid in the
vtkStructuredGridGeometryFIlter and obtained only the grid's points as
before.
Then I used vtkDataSetGeometryFilter and it worked. It even copied nicely
the cell data I had in the original grid.
I think this solved the problem.

  Thank you once again,

          Luca

Subject: [vtkusers] RFC: removing Mac OS X 10.6 support in VTK
Message-ID: <20160810183407.812025755@mail.rogue-research.com>

Hi all,

Does anybody care about Mac OS X 10.6 support anymore?

There are no longer any dashboards testing it automatically, and there are some burdensome workarounds in the codebase to support it.

Anyone object to its removal?, as per this patch:
<https://gitlab.kitware.com/vtk/vtk/merge_requests/1798>

(Apple no longer even releases security updates for 10.6, so using it is a bad idea in general.)

Cheers,

Yeah, Apple dropped support for it about 5 years ago... we upgraded our
last 10.6 machine around a year ago, and have been using a deployment
target of 10.7 since then.

I mentioned it in the MR, but I'll mention it again here: a reason why
people might not want to upgrade a Mac past 10.6 is that PowerPC apps will
not run on later versions of OS X.  It was awesome to be able to run old
PowerPC apps on an Intel Mac, I had a nice little viewer that I had to
retire when I upgraded.

Hello All,

Currently I am working on this example
<https://github.com/Kitware/VTK/blob/master/Examples/Annotation/Python/labeledMesh.py>
that teaches how to use vtkSelectVisiblePoints. As you can see, selection
window is 2D recatngle (visPts.SetSelection(xmin, xmin + xLength, ymin,
ymin + yLength)) in this example, does anybody know a trick/function that
can select contents of 3D cube?

Sincerely,

thank you for your suggestions. I rebuilt VTK with the DVTK_DEBUG_LEAKS flag
on and I am now seeing multiple leaks report. Time to dig into the code now!

Subject: [vtkusers] vtkArcSource vs vtkEllipseArcSource
Message-ID: <CA+fAcvp9kH-ZYLm-P=OhWcvM1L26VK7LrmD_Li1=Nb5qgGEiiw@mail.gmail.com>

Hello vtkusers,

I have VTK 7.0 and I am drawing an Arc against a plane surface. This Arc is
a representation of a Geometry(e.g. Plane). I have an algorithm that by
user information of Azimuth/Strike and Plunge/Dip returns a set of
vtkPoints. With these points, I am building a line using vtkLineSource to
represent my Plane/Arc as well as expected (attached pictures PlaneArc1 and
PlaneArc2) and worked smoothly.

Snapshot Code:
vtkSmartPointer<vtkPoints> PointViewGC = MyFunction(235/*Azimuth*/,
225/*Plunge*/);
vtkSmartPointer<vtkLineSource> lineDataGCO =
vtkSmartPointer<vtkLineSource>::New();
lineDataGCO->SetPoints(PointViewGC);

However, I am trying do the same with vtk ArcSource using the same set of
Points, but the result is not the correct.(Attached picture ArcSource1)
Snapshot Code:
vtkSmartPointer<vtkArcSource> arcSource =
vtkSmartPointer<vtkArcSource>::New();
arcSource->SetAngle(225);
arcSource->SetResolution(40);
vtkIdType numPts = PointViewGC->GetNumberOfPoints()-1;
double point1[3]; PointViewGC->GetPoint(1,point1);
double point2[3]; PointViewGC->GetPoint(numPts, point2);
arcSource->SetPoint1(point1);
arcSource->SetPoint1(point2);
arcSource->NegativeOff();
arcSource->UseNormalAndAngleOn();

After some research I found out that VTK 7 doesn't released
vtkEllipseArcSource classes, then I decided download from (
https://github.com/Kitware/VTK). The point is there anybody knows what's
wrong in my code? If vtkArcSource could handle itself my goals to draw this
geometry? And/or if vtkEllipseArcSource could solve my problem to justify I
do again a compilation of VTK just to integrate this class?

Many thanks for any help.

Regards,

Luis.

Hum, I've noticed a first oddity illustrated by the two variables below (both
being instances of 
vtkSmartPointer<vtkPolyData>):


(...)

this -> selected_cells_polydata -> Delete();
this -> unselected_cells_polydata -> Delete();

std::cout << this -> selected_cells_polydata-> GetActualMemorySize() <<
std::endl;
std::cout << this -> unselected_cells_polydata -> GetActualMemorySize() <<
std::endl;

(...)

The two calls to GetActualMemorySize() return non-zero memory usage, after
Delete() has been called. What am I missing here?

Hello friends,

I am trying to use vtk as a requirement for one of my projects. I am having
trouble compiling it using VS2015 - Is there somewhere I could find
detailed instructions on doing this. Specifically I am trying to locate the
file vtkgl.h. I have tried configuring vtk through Cmake and building
through VS, but at no step through this process is vtkgl.h locatable in my
vtk folder.

Thank you!

Subject: [vtkusers] help with rendering CT series into 3D graphic
Message-ID: <1470904020996-5739661.post@n5.nabble.com>

Hi all,

Any help or advise will help me a huge amount. I have been trying to render
a series of CT slices into a 3-D graphic, the window opens and the script
runs with no errors, however the image does not appear in the window.



Please see code below:






import vtk 

 

filepath = r"/Users/hp/Desktop/CT_Slice/"
dcmrder = vtk.vtkDICOMImageReader()
dcmrder.SetDirectoryName(filepath)
dcmrder.Update()
 
  

renderer = vtk.vtkRenderer()
renderwindow = vtk.vtkRenderWindow()
renderwindow.AddRenderer(renderer)
rndrint = vtk.vtkRenderWindowInteractor()
rndrint.SetRenderWindow(renderwindow)
  

renderer.SetBackground(0,0,0)
renderwindow.SetSize(720,720)
 


mc = vtk.vtkMarchingCubes()
mc.SetInputConnection(dcmrder.GetOutputPort())
mc.Update()
 

mapper = vtk.vtkPolyDataMapper()
mapper.SetInputConnection(mc.GetOutputPort())


actor = vtk.vtkActor()
actor.SetMapper(mapper)
    
renderer.AddActor(actor)
rndrint.Initialize()
rndrint.Start()

Subject: [vtkusers] Volume rendering problem
Message-ID: <CAE-7VJmA17ds3Ly6b-P9DYcDp=n5n295JzpbGjoRTkWeOLDdxg@mail.gmail.com>

Hi all,

I'm wrestling with a volume rendering problem.

I've set up a very basic pipeline that just renders a volume.

As source it uses a custom reader I wrote that loads a volume from a HDF5
dataset (float).

It seemed to be working fine with the volume I had been testing with (see
attached works_fine.png), which was a 120x120x2000. In addition to the the
rendering itself, the screenshot shows a histogram plot I was using for
debugging, as well as some editor controls I use to modify the
color/opacity transfer function.

I then tested with another volume which is larger (300x300x5000), but apart
from that has pretty much the same characteristic for its scalar values as
the first one, and all of a sudden I don't see anything. See the attached
not_working.png, which shows the setup using the problematic volume.

As you can in the histogram, there's a lot of voxel values roughly around
1, much like in the first volume, so I would expect that with the same
transfer functions (black color, and an opacity ramp from 0.0,0.0 up to
5.0,1.0), I should see _something_.

I'm pretty sure I'm missing something basic here, but does anyone have an
idea why I get the expected rendering with my smaller volume, but not with
the bigger one?

Thanks a lot for any advice!

Elvis

PS. If you're confused by the range of the vtkAxisActor that you see in the
screenshots, when comparing to the the volume sizes I stated above, it's
because my custom render currently hardcodes the spacing to 0.2. DS.

I can give some snippets from my code which shows how I set up rendering
and how I show the histogram:

The pipeline is basically just:

        auto volumeMapper =
vtkSmartPointer<vtkGPUVolumeRayCastMapper>::New();
        volumeMapper->SetInputData(imageData);

        auto volumeProperty = vtkSmartPointer<vtkVolumeProperty>::New();
        volumeProperty->SetInterpolationTypeToLinear();
        volumeProperty->ShadeOff();

        auto opacity = vtkSmartPointer<vtkPiecewiseFunction>::New();
        opacity->AddPoint(0.0, 0.0);
        opacity->AddPoint(5.0, 1.0);

        auto volume = vtkSmartPointer<vtkVolume>::New();
        volume->SetMapper(volumeMapper);
        volume->SetProperty(volumeProperty);
        renderer()->AddVolume(volume);

where imageData is the vtkImageData as loaded by my custom reader.

The camera is configured with:

        auto camera = renderer()->GetActiveCamera();
        camera->SetParallelProjection(true);
        camera->SetPosition(3000.0, 0.0, 0.0);
        camera->SetFocalPoint(0.0, 0.0, 0.0);
        camera->SetViewUp(0, 0, 1);

And the histogram plot I use for debugging is set up with:

    auto imageHistogramStatistics =
vtkSmartPointer<vtkImageHistogramStatistics>::New();
    imageHistogramStatistics->SetInputData(imageData);
    imageHistogramStatistics->Update();

    qDebug() << "Image Histogram Statistics:";
    qDebug() << "  min:" << imageHistogramStatistics->GetMinimum();
    qDebug() << "  max:" << imageHistogramStatistics->GetMaximum();
    qDebug() << "  mean:" << imageHistogramStatistics->GetMean();
    qDebug() << "  dev:" <<
imageHistogramStatistics->GetStandardDeviation();

    auto imageAccumulate = vtkSmartPointer<vtkImageAccumulate>::New();
    imageAccumulate->SetComponentSpacing(0.01, 0, 0);
    imageAccumulate->SetComponentExtent(0, 499, 0, 0, 0, 0);
    imageAccumulate->SetInputData(imageData);
    imageAccumulate->Update();

    auto plot = vtkSmartPointer<vtkXYPlotActor>::New();
    plot->ExchangeAxesOff();
    plot->SetXTitle("");
    plot->SetYTitle("");
    plot->SetLabelFormat("%g");
    plot->SetXValuesToValue();
    plot->AddDataSetInputConnection(imageAccumulate->GetOutputPort());

    renderer()->AddActor(plot);

Where imageData is the rendered vtkImageData.

Sorry, shortly after sending this I think I got one step closer to an
explanation. The file from which I load this second, larger, volume is
actually a concatenation of several files, and I just tried loading one of
the files separately and it worked fine (the rendering looks as expected).
So something is probably wrong in the script I use for concatenating HDF5
files. I'll do some digging there.

Okay, I found the problem for my application myself. It seems that the 
scenario I have mentioned below in my very first e-mail (application 
depends on a number of dlls, each dll statically links VTK) does not 
work (as it is the case with many other libraries). The reason is that 
static variables defined in VTK are replicated in each dll, making them 
inconsistent.

Still, as mentioned below, I could reproduce the crash of the VTK 
FourPaneViewer once, which might be related to a different problem.

Thanks,

      Sophonet

There seems to be nothing wrong with the concatenation script I'm using.
I've now tried creating smaller volumes by not concatenating the full set
of files, and up until a resulting volume of around ~2500x300x300 it works
okay, but if I extend the volume more than that, the rendering fails like
described previously. It's quite strange :/ And I don't think I'm hitting
some out-of-memory condition inside VTK, since it normally prints nice
errors and crashes if that happens.

If the objects have been freed, the results of calling their methods
are unpredictable -- I'm surprised this didn't segfault off the bat.
It's likely returning stale/garbage memory.

Alternatively, remember that Delete() doesn't always free the object
-- it just decrements the reference count and will only free memory
once the reference count reaches 0. So if there's another existing
reference (for instance, from the vtkSmartPointer), the object will
still exist and hold memory. You can call GetReferenceCount() on them
to see how many references are currently held.

HTH,
Dave

I'm beginning to think that maybe I'm running out of graphics memory? Could
this be a symptom of that?

I've now created a minimal test case, and would very much appreciate if
someone could try it out to see if they get the same problem:

Download

   https://drive.google.com/open?id=0B1a2u6qVxaL7M1B6bFhreE1RQW8

and extract the .tar archive (162 MB since it includes two volumes). Then

   cmake .
   make
   ./voltest working.hdf5
   ./voltest not_working.hdf5

For me, rendering of working.hdf5 works, but not rendering of
not_working.hdf5. Is that the case also for you?

The only difference between the two volumes is that not_working.hdf5 is
slightly larger than working.hdf5 (2500 voxels high vs 2000). Apart from
that they were both created in the same way.

Thanks a lot in advance,
Elvis

Thanks for the update, Sophonet.

My application (and probably FourPaneViewer) is probably having the same
problem.
For now, I'm using dynamic linking, but I'll keep checking on this thread
because I'll need them to be static in the future.

Just as a note, statically linking to VTK should be possible if you have 
a single, self-contained executable (with no dependencies to dlls which 
also link to VTK), since static variables only appear once, as intended. 
Therefore, the FourPaneViewer should not be affected by the problem I 
was describing below.

You run into problems if you have an executable which depends on 
additional shared libraries (dlls). In that case, VTK needs to be built 
dynamic as well.

To summarize: To be on the safe side, either build every library you 
need for an executable as shared, or build them all as static. Mixing 
static with dynamic libraries might cause the problems I have described.

Message-ID: <CAKKNfuJntdUKFq1dcTaG5dh3sT=m_AXjOZkD0VWsCtCtgNfP=Q@mail.gmail.com>

Hi,

Is there a method to convert a STL file to DCM slices?

I'm able to export a DCM serie to STL but I couldn't find the other way
around.

thanks,

Matias.

Some systems only support up to 4096 as a 3D texture dimension, maybe try
300x300x4096 -Ken

Ah, but in the test case, the working volume is 2000x300x300, while the
non-working one is 2500x300x300. So both volumes in the test case are well
below 4096 (though in the end, I want to render a 5000x300x300 volume).

I just had a collegue try the test case. He's on a pretty similar (but
probably slightly beefier) intel graphics chipset, and he could reproduce
the problem.

It would be very interesting if someone could try the test case on a
machine with more powerful graphics.

An interesting this is that, if I change

        opacity->AddPoint(0.0, 0.00);

in my test case to

        opacity->AddPoint(0.0, 0.01);

i.e. raising the left endpoint of my opacity transfer function just a
little bit, I get _some_ rendering. But from the looks of it, the rendering
I get is as if all the scalars of the vtkImageData is 0.0, even if they
evidently are not.

David, 

thanks for clarifying. Indeed, I was not using Delete() properly. 

Initialize() seems to fit my purpose better, as its documentation reads
"Restore object to initial state. Release memory back to system.". I can
indeed observe that a given member's memory usage goes to zero after I call
its Initialize() method and GetActualMemorySize afterwards. 

However, the total memory usage (as calculated by Xcode) of the program does
not change whether I use Initialize() or not. The freed memory has to go
somewhere still ?

The code looks fine to me, I'm not sure why the text is coming out
grey. A few ideas that might help track the issue down:

1) Print out the color and opacity properties in the vtkTextPropery
objects to verify them. Maybe there's a surprise in there.
2) Try turning off the point/line/polygon smoothing and see if that's
somehow interacting with the rendering.
3) Try using one of the standard fonts bundled with VTK (e.g.
SetFontFamilyToTimes() or similar)).

I was going to try that, but since vtkVolumeRayCastMapper does not support
rendering float data directly, I'd have to convert my two test files to
unsigned short instead, and also store it in a different format, since my
HDF5 reader is pretty basic and only works with float input and output so
far.

I might do that actually, since I'm suspecting more and more that this
might be the issue.

volumeMapper->GetMaxMemoryInBytes() reports 128 MB, of which I think it'll
use 75% by default, so 96 MB. Anyone know off-hand if this would be too
little GPU memory to render a 2500x300x300 volume?

In any case, shouldn't VTK print some error if it can't allocate enough GPU
memory? In fact, I seem to remember getting some error like that in the
past. With my problematic volume in this case, VTK is not printing anything.

I'll try to find a machine with more powerful graphics and try my test case
there. If someone has the time to try it on their machine though, I'd
appreciate it a lot. It only requires VTK7 with OpenGL2 rendering backend
and the HDF5 library (C++ interface) to compile.

By inserting a vtkExtractVOI between my reader and mapper, and then loading
my problematic 300x300x2500 volume, I was able to debug some more:

With

    extract->SetVOI(0, 299, 0, 299, 0, 2047);

it works, while with:

    extract->SetVOI(0, 299, 0, 299, 0, 2048);

it does not.

2048 is such a special number that I don't think it's a coincidence that
this is the breaking point. It is probably a texture size limitation of my
graphics card then? :( (it's a Intel HD 4400 on a Haswell laptop).

Hi Elvis,
I tested it on my nvidia geforce gtx 770 with 4GB of vram and I have the
same problem. With the larger dataset the volume is not rendered.
Best regard
Robert

Thanks a lot for testing Robert. Do you happen to know what the maximum
texture size is for that GPU?

I think now I'm fairly confident that I'm hitting some maximum texture size
limit at 2048 for the Intel GPU I'm using.

it's also 2048. According to this
https://developer.apple.com/opengl/capabilities/ AMD graphics should have
the limit at 8192-16348, but right now I don't have any to test it.

Great, glad that's figured out.

See my earlier comments about OS caching. The operating system is
likely reserving some of the freed memory as cache memory to be reused
by the application. Google around a bit and see if you can find some
way to free/check the per-process cached memory for your operating
system.

HTH,
Dave

I am not aware of any straighforward way to do this. 

Have a look at binvox

One way would be to voxelize your mesh, then convert to nrrd (e.g. binvox) 
then to dcm.

You would have to look into creating one dcm file per slice or one multislice 
dcm file.

It can be done.

Alright, thanks.

I guess I'll have to simply give up the idea of rendering such a large
volume on this hardware. I may split it into multiple volumes, or work with
a downsampled version.

The program I'm working on will have an "overview" view, which is what I'm
working on now. And in this view it probably makes sense to work with a
downsampled version. It will also have a detailed view for looking closer
at the volume, but restricted to only show parts of it it up to a maximum
size. In that view I can use the original data.

Elvis, Robert,

Alvaro is looking into this issue. Hopefully soon we will have few answers.
The bottom line is that in a pure opengl application, we were able to
render texture larger than 4GB but it is too early to say where the
bottleneck is.

FYI:


We got past another one of the hurdles we were facing here.


One of my colleagues found out how to build an Android app (MyApp.apk)

with dependency on VTK 7.0 libraries.


It turns out that the order of VTK libraries matters and is the opposite of the way

we had initially assumed, with common libraries listed last instead of first.


So we now have something like this in our build.gradle file:


...


        ndk {
            moduleName "myLibraryName"
            cppFlags.add("-std=c++11")
            cppFlags.add("-fexceptions")
            cppFlags.add("-frtti")
            cppFlags.add("-I${OTHER_INCLUDE_DIR}".toString())
            cppFlags.add("-I${VTK_INCLUDE_DIR}".toString())

            ldLibs.addAll(["dl", "log", "z", "android", "EGL", "GLESv2"])
            stl "gnustl_shared"
        }


        productFlavors {
            create("arm64-v8a") {
                ndk {
                    abiFilters.add("arm64-v8a")
                    ldFlags.add("-L${OTHER_LIB_DIR}".toString())
                    ldLibs.add("other")
                    ldFlags.add("-L${VTK_LIB_DIR}".toString())
                    ldLibs.add("vtkRenderingOpenGL2-7.0")
                    ldLibs.add("vtkglew-7.0")

Subject: [vtkusers] Android support for off-screen rendering
References: <CGME20160812001009uscas1p11ff8b8f759996513539145c758ddd64e@uscas1p1.samsung.com>
Message-ID: <a083c659153b4806be4cc0361d3e40f9@sraex01sc.sisa.samsung.com>


However, now I am running into another issue on Android.

I want to read an obj file, render off-screen (in memory, not to an actual window)
and then get a pointer to the vtkImageData.

I was planning to use vtkRenderWindow method SetOffScreenRendering(1);

I got this working in a simple Linux desktop test program.

However, I noticed that this is not officially supported for Android platform.

In VTK-7.0.0/CMake/vtkOpenGL.cmake file, lines 33-35 :

 if (VTK_USE_OFFSCREEN_EGL AND ANDROID)
   message(FATAL_ERROR "You cannot use VTK_USE_OFFSCREEN_EGL on the ANDROID platform")
 endif()

and in vtkEGLRenderWindow.cxx, lines 614-618 :

//----------------------------------------------------------------------------
void vtkEGLRenderWindow::SetOffScreenRendering (int)
{
  // this is determined at compile time: ANDROID -> 0, VTK_USE_OFFSCREEN_EGL -> 1
}

Why is this, and has anyone tried modifying VTK to allow for this.

Looked properties of color and transparency, all right. Use a standard font
does not help. 

Previously had a similar problem, but to solve a sequence of drawing
elements (used VTK 6.1), but now it does not help.

There are ideas?

Thank you. That helped:
2) Try turning off the point/line/polygon smoothing and see if that's 
somehow interacting with the rendering.

Subject: [vtkusers] Throwing exception when integrating
 vtkOrientationMarkerWidget into VTKWeb
Message-ID: <1470982315705.6172@sphic.org.cn>

?Hi all,


I'd like to integrate vtkOrientationMarkerWidget into vtk_web_cone.py.  When I run this code and open a browser to http://localhost:8080/apps/cone, I encountered an exception (pls see attached fig1). Then, I chose Debug to look into where throws this exception(pls see attached fig2). I list my code below. What's the problem? I guess it may be related to "widget.SetInteractor(renderWindowInteractor)". Any suggestions are welcomed. Thanks in advance.


Regards,

Subject: [vtkusers] vtkXYPlotActor fit viewport?
Message-ID: <CAE-7VJkWfkuKL5_q0BdbnwG9u=0Rg=Atq66pEG3xKNaAL7JZ2A@mail.gmail.com>

I have a little debug widget in which I show a vtkXYPlotActor like this:

    auto imageAccumulate = vtkSmartPointer<vtkImageAccumulate>::New();
    imageAccumulate->SetComponentSpacing(0.01, 0, 0);
    imageAccumulate->SetComponentExtent(0, 499, 0, 0, 0, 0);
    imageAccumulate->SetInputData(imageData);
    imageAccumulate->Update();

    auto plot = vtkSmartPointer<vtkXYPlotActor>::New();
    plot->ExchangeAxesOff();
    plot->SetXTitle("");
    plot->SetYTitle("");
    plot->SetLabelFormat("%g");
    plot->SetXValuesToValue();
    plot->AddDataSetInputConnection(imageAccumulate->GetOutputPort());

    renderer()->AddActor(plot);
    auto camera = renderer()->GetActiveCamera();
    camera->Zoom(3);

The camera->Zoom(3) seems to have no effect (see attached screenshot). My
goal is actually to set a zoom level such that the vtkXYPlotActor is as
large as it can be without going outside the viewport.

How can this be done?

Thanks,
Elvis

Nevermind, I figured out that I can do

    plot->GetPositionCoordinate()->SetValue(0, 0);
    plot->GetPosition2Coordinate()->SetValue(1, 1);

Message-ID: <CANFuGOqZy-p1Yd5o2VWRTGWS2W=edfcrfHktV=+Q+EDd21bNwg@mail.gmail.com>

I can compile and run the code OK when running a debug config. When I
switch to release it crashes with a Microsoft C++ exception:
std::bad_alloc. And I get this is a dialog

Unhandled exception at 0x00007FFDA170EA1E (ucrtbase.dll) in mesh_maker.exe:
Fatal program exit requested.

I'm pretty sure that this has nothing to do with VTK but has anyone out
there come across this sort of behavior?

This is the cmake file I used to create the sln file (copied from the VTK
examples).

cmake_minimum_required(VERSION 2.8)

PROJECT(MeshMaker)

find_package(VTK REQUIRED)
include(${VTK_USE_FILE})

add_executable(mesh_maker FileIterator poly_maker mesh_maker)

if(VTK_LIBRARIES)
  target_link_libraries(mesh_maker ${VTK_LIBRARIES})
else()
  target_link_libraries(mesh_maker vtkHybrid vtkWidgets)
endif()

The VTK it points to was built in release mode using MSVC.

Cheers
Ollie

Subject: [vtkusers] Multiple repeating timers associated with an interactor
Message-ID: <CAJ=jcXuv5jSUxxBmKD1Rn1uGYyX27FPpbB=EWihopmoqFfcQ0Q@mail.gmail.com>

Dear VTK community,?

I am trying to create 2 different repeating timers (one every 105 ms and
the other one every 202 ms for example) and associate them with a
vtkinteractor.

I have no problem to do it for each one of them but I cannot add them
simultaneously without having them sharing the same timerdelay...

I am currently using the following code:
minteractor->AddObserver(vtkCommand::TimerEvent,  GetTimer1Object());
m_Timer1Id = minteractor->CreateRepeatingTimer(GetTimer1StepValue());

minteractor->AddObserver(vtkCommand::TimerEvent,  GetTimer2Object());
m_Timer2Id = minteractor->CreateRepeatingTimer(GetTimer2StepValue());


Is there a way to associate the observers to their timer id? So that they
do not share the same repeating timer?

Thanks in advance,
R?mi

Nice, glad that fixed it. You might be interested in MSAA
(vtkRenderWindow::SetMultiSamples), an alternative antialiasing
solution.

Hi Matias,
As far as I know there is no direct converted available for STL to DCM.
But if you do this workaround it is possible :

STL -> VTP (polydata) -> DCM

Once you have the data in polydata format, you will be able to slice it
using ParaView.

The following links might help you

http://stackoverflow.com/questions/36193779/generating-and-reading-vtk-files-from-dcm-files-and-modifying-model
https://itk.org/Doxygen46/html/IO_2DicomSeriesReadImageWrite2_8cxx-example.html

vtkSTLReader is the class you need to use to read the STL file within VTK.

Thanks,
Chiranjib

Message-ID: <7099B871-B496-4CF8-8100-E86F048E8775@gmail.com>

Hi,

I created a vtkPath representing a curve of consecutive bezier curves (adding control points as sequences of vtkPath::MOVE_TO and 3x vtkPath::CUBIC_CURVE), but I can?t figure out how to render the Bezier curves represented by these control points.

vtkPath doesn't have any examples and googling it gives too many topics related to build/configuration (as in "VTKPATH").

Can anyone help me how to render them?


Thanks,

Enzo

At this point, you cannot render them. They were added as an
implementation detail of the vector graphics exporter for embedding
pre-rendered text in PDF/SVG/etc. There hasn't been a need to directly
render them yet, so there is unfortunately no support for this.

Thanks David.

I just found out about vtkBezierContourLineInterpolator used as supplementary to vtkContourWidget.
Is there any way I can use those control points to manually draw a bezier curve using the vtkContourWidget?

I'm not familiar with that code, but it might be possible. You
wouldn't be able to use the vtkPath object directly, though, since the
contour code was written before vtkPath existed.

Maybe someone more familiar with vtkBezierContourLineInterpolator can
comment on it's usage?

Mr. Oregon Duckman,

Both vtkImageData and vtkPolyData are subclasses of vtkDataSet, so
they are already vtkDataSets.

Do you mean you have a vtkDataSet that is going to be either a
vtkImage or vtkPolyData, and you want to downcast it to the right
type? If so, you can do the following:

vtkDataSet* dataset = ...;
vtkImageData* imageData = vtkImageData::SafeDownCast(dataset);
vtkPolyData* polyData = vtkPolyData::SafeDownCast(dataset);

if (imageData) {
   // handle the case for vtkImageData
} else if (polyData){
  // handle the case for vtkPolyData
} else {
   std::cerr << "unknown type" << std::endl;
}

HTH,
Cory

Subject: [vtkusers] can vtkDiscretizableColorTransferFunction deal with
 non-contiguous dicrete values?
Message-ID: <CAFuWFr+xu9h0nrSpb80_u3Ocrijt68r6qzLTdQAEEuXC9rakxA@mail.gmail.com>

    Hi everybody,

I am trying to use  vtkDiscretizedColorTransferFunction in order to assign
predefined colors to a variable number of fixed values.
With the settings specified in the code below, the table works fine as soon
as the values are contiguous, e.g., 3->4->5->6->7->8. But if I provide a
list of non-contiguous ids, such as 3->5->6->7->8, the table apparently
shifts the colors.
Can  anybody help me understand what I  am missing?
Thanks for any help

        Luca

Here is my code:

// This is an example
std::vetor<uint32> listIds = {3, 5, 6, 7, 8};
table = vtkSmartPointer<vtkDiscretizableColorTransferFunction>::New();
    table->DiscretizeOn();
    table->IndexedLookupOff();

    table->SetNumberOfValues(listIds.size());
    foreach (uint32 id, listaIds) {

        QColor color(myFunctionTogetColorsFromIds(id))
        double r = color.redF();
        double g = color.greenF();
        double b = color.blueF();
        table->AddRGBPoint(static_cast<double>(id), r, g, b);
    }
    table->Build();

Hi all,

I've been able to successfully build Activiz 6.2 (both x86 and x64) thanks
to all of the knowledge in this thread and the files provided by Mark. 

I'm wondering if anyone has been able to successfully build Activiz 6.2 (or
above) with the underlying VTK compiled for OpenGL2. I think I need to add
references to the vtK...OpenGL2 libraries in the Activiz CMake, but I have
yet to be able to do that successfully.

Thanks,
Zamir

Subject: [vtkusers] why my computing gray scale histogram of DICOM files is
 different from mimics
Message-ID: <50b38d0b.15.15689c128f2.Coremail.tjlp@netease.com>

Hi,

I try to get the grayscale of points in DICOM files and draw the histogram using .NET component, and what I get is different from the histogram of MIMICS. My C# code is as follow, the returned vtkLongArray stores the grayscale statistic result, value of element is the total number of the point whose gray scale value is equal to the array index:

public vtkLongArray GetGreyScaleStatisticsFromImageData(vtkImageData data, out long min_grey, out long max_grey)
{
            vtkImageExtractComponents extract = vtkImageExtractComponents.New();
            extract.SetInputData(data);
            extract.SetComponents(0);
            extract.Update();

            double[] scalarrange = extract.GetOutput().GetScalarRange();
            min_grey = (long)scalarrange[0];
            max_grey = (long)scalarrange[1];
            long size = (long)(scalarrange[1] - scalarrange[0]);
            vtkImageAccumulate histogram = vtkImageAccumulate.New();
            histogram.SetInputConnection(extract.GetOutputPort());
            histogram.SetComponentExtent((int)min_grey, (int)max_grey, 0, 0, 0, 0);
            histogram.SetComponentOrigin(0, 0, 0);
            histogram.SetComponentSpacing(1, 0, 0);
            histogram.SetIgnoreZero(1);
            histogram.Update();
            vtkLongArray count = vtkLongArray.New();
            count.SetNumberOfComponents(1);
            count.SetNumberOfTuples(size);
            IntPtr value = histogram.GetOutput().GetScalarPointer();
            string scalartype = histogram.GetOutput().GetScalarTypeAsString();
            int s = histogram.GetOutput().GetScalarSize();
            long[] managedValArray = new long[size];
            Marshal.Copy(value, managedValArray, 0, managedValArray.Length);
            for(int i=0; i<managedValArray.Length; i++)
            {
                count.SetTuple1(i, managedValArray[i]);
            }
            return count;
}

The images of my and MIMICS are attached.

Does any guys know that?

Thanks

Two differences:

1) MIMICS is showing a log plot
2) The plot is shifted by the RescaleIntercept

Subject: [vtkusers] Sharing polyline vtkPoints with trangle strip
Message-ID: <VI1PR0202MB262263EB4013123723F2B52CE9110@VI1PR0202MB2622.eurprd02.prod.outlook.com>

Hi,

I am using multiple vtkTriangleStrips to render tubes with differing cross-section at each end, e.g. an ellipse at one end and a square at the other end. I am overlaying each of the tube's ends with a vtkPolyLine of contrasting colour to allow the user to view just the end cross-sections and hide the triangulated tube surface. I am creating a repeating timer on the interactor to animate the scene.

I have a separate vtkActor for each of the polylines and the triangle strip. Each of the ends of a tube can be translated and oriented differently when the animation is running.

The issue I have is that I can't find a way of specifying multiple vtkPoints arrays (i.e. one for each polyline) as input to the triangle strip, so I am creating a new vtkPoints array for the triangle strip's vtkPolyData and populating it with the vtkPoints arrays for each polyline in turn. This is repeated at each step in the animation, causing a significant performance hotspot when the number of tubes is scaled up:

// Update triangle strip to reflect transformed polylines
// Get points for each end
vtkPoints points = polylineEnd1Actor().GetMapper().GetInput().GetCell(0).GetPoints();
vtkPoints pointsEnd2 = polylineEnd2Actor().GetMapper().GetInput().GetCell(0).GetPoints();

// Create a new vtkPoints for triangle strip
int pointCountEnd2 = pointsEnd2.GetNumberOfPoints();
for (int i = 0; i < pointCountEnd2; ++i)
{
  // Append transformed pointsEnd2 to points for triangle strip poly data
  points.InsertNextPoint(pointsEnd2.GetPoint(i)[0], pointsEnd2.GetPoint(i)[1], pointsEnd2.GetPoint(i)[2]);
}

PolyDataForTriangleStrip.SetPoints(points);
PolyDataForTriangleStrip.Modified();
PolyDataNormalsForTriangleStrip.SetInputData(PolyDataForTriangleStrip);
PolyDataNormalsForTriangleStrip.Update();

I would like to find a way of mapping polydata/points of the two polylines directly to the triangle strip's polydata/points, such that when the polyline actors are transformed, their new point coordinates are reflected in the triangle strip without having to create a new vtkPoints.

I am using ActiViz.Net with C#.

Hi, David,

Thanks for your point.

I understand the plot shift. It just change the gray scale value range from [-1023, 2016] to [0, 3140]. This does not impact the generated graph shape.

Would you like to explain how to show log plot according to my code?

Thanks

Two differences:


1) MIMICS is showing a log plot
2) The plot is shifted by the RescaleIntercept

Hi Liu Peng,

Take the log of count. Or log of count+1, to avoid log(0).
It will probably be like this:

            for(int i=0; i<managedValArray.Length; i++)
            {
                count.SetTuple1(i, log(1 + managedValArray[i]));
            }

Subject: [vtkusers] Sharing polyline vtkPoints with trangle strip
Message-ID: <VI1PR0202MB262215C8D8DF72A664F10732E9120@VI1PR0202MB2622.eurprd02.prod.outlook.com>

Hi,

I am using multiple vtkTriangleStrips to render tubes with differing cross-section at each end, e.g. an ellipse at one end and a square at the other end. I am overlaying each of the tube's ends with a vtkPolyLine of contrasting colour to allow the user to view just the end cross-sections and hide the triangulated tube surface. I am creating a repeating timer on the interactor to animate the scene.

I have a separate vtkActor for each of the polylines and the triangle strip. Each of the ends of a tube can be translated and oriented differently when the animation is running.

The issue I have is that I can't find a way of specifying multiple vtkPoints arrays (i.e. one for each polyline) as input to the triangle strip, so I am creating a new vtkPoints array for the triangle strip's vtkPolyData and populating it with the vtkPoints arrays for each polyline in turn. This is repeated at each step in the animation, causing a significant performance hotspot when the number of tubes is scaled up:

// Update triangle strip to reflect transformed polylines
// Get points for each end
vtkPoints points = polylineEnd1Actor().GetMapper().GetInput().GetCell(0).GetPoints();
vtkPoints pointsEnd2 = polylineEnd2Actor().GetMapper().GetInput().GetCell(0).GetPoints();

// Create a new vtkPoints for triangle strip
int pointCountEnd2 = pointsEnd2.GetNumberOfPoints();
for (int i = 0; i < pointCountEnd2; ++i)
{
  // Append transformed pointsEnd2 to points for triangle strip poly data
  points.InsertNextPoint(pointsEnd2.GetPoint(i)[0], pointsEnd2.GetPoint(i)[1], pointsEnd2.GetPoint(i)[2]);
}

PolyDataForTriangleStrip.SetPoints(points);
PolyDataForTriangleStrip.Modified();
PolyDataNormalsForTriangleStrip.SetInputData(PolyDataForTriangleStrip);
PolyDataNormalsForTriangleStrip.Update();

I would like to find a way of mapping polydata/points of the two polylines directly to the triangle strip's polydata/points, such that when the polyline actors are transformed, their new point coordinates are reflected in the triangle strip without having to create a new vtkPoints.

I am using ActiViz.Net with C#.

Hi Matias,

Thank you for your response! Is there a way for you to share the CMake and
additional Activiz source changes you used to get the build working? I have
already built VTK for OpenGL2 (both x86 and x64 as I would like to have
both).

Thanks,
Zamir

Subject: [vtkusers] can vtkDiscretizableColorTransferFunction deal with
 non-contiguous dicrete values?
Message-ID: <CAFuWFrJGUOk+zDQbxBCnbQyyqWCm95kU6gLeYbzWjkQ=1ExyCw@mail.gmail.com>

Hi everibody, I found the example TestColorByCellDataStringArray.cxx that
creates a categorical LookupTable using
vtkDiscretizableColorTransferFunction. I had to switch the IndexedColor
flag on and provide the colors using the SetIndexedColor(value, annotation)
method, where value is a vtkVariant object containing the current
celldata's unsigned short id (this is the type of data that I am storing in
the cells) and annotation is a vtkStdString.
It worked fine. I am appending  the code in case anybody need the same
feature.

      Thank you,

Luca Pallozzi Lavorante

// This is an example

std::vetor<uint32> listIds = {3, 5, 6, 7, 8};

table = vtkSmartPointer<vtkDiscretizableColorTransferFunction>::New();
table->IndexedLookupOn();

table->SetNumberOfIndexedColors(listIds.size());

size_t colorIndex = 0;

foreach (uint32 id, listaIds) {

   QColor color(myFunctionTogetColorsFromIds(id));
    vtkVariant value(static_cast<unsigned short>(id));

    vtkStdString annotation (nameOfMyId());

    table->SetIndexedColor(colorIndex, color.redF(), color.greenF(),
color.blueF());
    table->SetAnnotation(value, annotation);
    colorIndex++;
}

// table->Build(); // This was not necessary

Hi,David,

I try the log plot. It is more similar to MIMICS. However, it is not smooth yet.

Refer to the attachment for the graph.


Any suggestions?

Thanks.
Liu Peng

Hi Liu Peng,


Take the log of count. Or log of count+1, to avoid log(0).
It will probably be like this:


            for(int i=0; i<managedValArray.Length; i++)
            {
                count.SetTuple1(i, log(1 + managedValArray[i]));
            }

Hi, David,

Thanks for your point.

I understand the plot shift. It just change the gray scale value range from [-1023, 2016] to [0, 3140]. This does not impact the generated graph shape.

Would you like to explain how to show log plot according to my code?

Thanks

Two differences:


1) MIMICS is showing a log plot
2) The plot is shifted by the RescaleIntercept

Thanks, GetNextCell returns content of the cell. I was trying to see if
anyhow there is an identification for each cell(a label, or number) that
can be accessed or changed.

Subject: [vtkusers] Missing Configuration Variables
Message-ID: <CAFidDTUjXbRsV=EbCEt-uuQJjPnazi5ODrcive+OvstqXPXFeg@mail.gmail.com>

Hello friends,

I am currently building VTK through CMake as a dependency for an open
source project I am compiling. In their Documentation they specify toggling
of the variables

- VTK_USE_GUISUPPORT
- VTK_USE_PARALLEL
- VTK_USE_VIDEO_FOR_LINUX

I cannot seem to find these variables in the Cmake configurations.
How it be possible that I am using the wrong version of VTK?

Thanks!

Hello, 
from my experience, those can probably be set up by adding the following
directive to the cmake command line (when configuring the VTK build):

cmake [...] -DVTK_USE_GUISUPPORT:BOOL=ON (etc)

You can also use Ccmake and toggle the "Advanced" configuration mode to see
the status (enabled/disabled) of all configurations variables.

Cheers, 
Ben

Hi Saeed,

I?ve added extra per-point application data to my VTK models using the vtkFieldData addArray/getArray methods.  The data can be stored in the vtkDataSet (vtkPolyData in my case) or in the vtkCellData that accompanies it and can be any type of your choosing.

I can provide some concrete examples if that sounds more like what you?re trying to do.

Hi.

I am trying to do a variation on "surface with edges".  I subdivide the
surface polygons and put new scalar values at the vertices of the
sub-polygons.  This is working just fine.  However, I want to show "surface
with edges", but I want the original edges, not the subdivided ones.
I've tried several approaches, without success.

Approach 1:

I recall OpenGL having an edge flag that did the kind of thing I'm after:
as I'd issue glVertex calls between a glBegin and a glEnd, I could also set
the edge flag for whether the edge was to be visible.

Searching around in VTK, I see that VtkDataSetAttributes has EDGEFLAG as
one of its AttributeTypes.  I'm afraid I don't understand, because my use
of attributes has been scalar or vector values associated with points, but
the edge flag wouldn't be associated with points, but rather with, well,
edges.  I haven't been able to find an example that uses this, so I'm
questioning whether it's even the same thing.

Approach 2:

I have the original polygons (from before the subdivision).  I Figured I
could just draw "surface with edges" for those, but set their opacity to 0,
and leave the edge opacity at 1.  It appears that the cell opacity applies
to both the cell and the edges, and I don't see a way to set them
independently.  Although edge visibility can be toggled, I don't see a way
to toggle the surface visibility while leaving edges visible.

Approach 3:

I extracted the edges from the original polygons, and tried drawing them
together with the subdivided polygons (where the subdivided polygon edge
visibility is off).  This is resulted in what I was after, except there's z
fighting between the original edges and the subdivided surfaces.  I read
about the various ResoveCoincidentTopology options, but those appear to be
for a polygon with it's own edges, not a polygon with some other edges.  I
played with them anyway, just in case, but didn't see anything promising.

So... Am I barking up the wrong trees?  How should I show one set of edges
on top of another set of polygons?  I'm using python 2.6, talking to
vtk-5.10.

Thanks in advance for any help.

Subject: [vtkusers] set Attributes and Uniforms in VTK7/OpenGL2
Message-ID: <062cb5e7-077b-bc38-98b9-9f2aad796522@cg.tuwien.ac.at>

Hi,

I have two meshes A and B, where the vertex coordinates of A should be 
assigned as texture coordinates of the B.

I use vtkOpenGLPolyDataMapper together with a custom vertex and fragment 
shader, without creating my own vtkShaderCache or vtkShaderProgram objects.
However, I do use a vtkTextureObject that creates and binds the texture. 
This works fine, when I set only A as input data for the mapper.

Now I want to send the vertex data of B to the shader program. There are 
some attributes such as vertexMC that I can use in the shader code, but 
I don't know where they are set. I guess I need to set some uniforms and 
attributes (specifically, the vertex coordinates of B), but don't know how.
Is there a way to get the currently used shader program and send some 
attributes and uniform variables to it?

Thanks for the help!

Cheers

Hai

Message-ID: <bf81f05ebe6c49009e54c7023f4a7dbf@exch-mbx-c02.zv.hs-niederrhein.local>

Hi Everybody

I am looking for somebody using  wxVTKRenderWindowInteractor  (also VTK with wxWidgets) under Ubuntu Linux ?

I have troubles finding gtk and its gdk  there.

And - the question is what to do with versions of wxWidgets higher then 2.8, probably this is as well an issue which could solve my problem?
Under Windows it works fine with the same versions (wxWidgets 3.0 and VTK6.3 )

The file was long time not more maintained but has done very good job until know, here both project links
wxvtk.sourceforge.net
https://www.openhub.net/p/wxVTK

Best regards

Yordan

Subject: [vtkusers] Extracting a vtkLine from vtkPolyData
Message-ID: <93B1CB6B-D8BC-4FD0-A601-BA00C18111C3@icr.ac.uk>

Hi all,

I have a vtkPolyData which consists of a set of closed vtkLines. I would like to select a specific line from this set, based on the Z coordinates of points in the line.

I have been looking at examples which use vtkSelectionNode with the threshold option. The problem is, these seem to require a separate vtkDataArray associated with the points that you wish to threshold. Is it possible to search purely based on the point coordinates?

Kind regards,

Dave

Update, I think I got this. The uniforms can be set over the 
UpdateShaderEvent.

Thanks

Now I'm looking at the code, I don't think I built this using OpenGL2, in
fact I was trying to Build ActiViz 7.0 with OpenGL2 and I was running into
issues. see if the code I sent works for you.

Subject: [vtkusers] Remove all VTK 2D Actors
Message-ID: <CAGdd0Q5MACQ+W0DPW378AqVirDTe8-ZKbJW-jBKZZqrApFktVA@mail.gmail.com>

Hi All,

Is there a method to remove all 2D actors in a vtk Scene?
renderer->RemoveAllViewProps() can't resolve my problem.

Best,
Saeed

Thank you, Matias! I have downloaded the code and will examine it within
the next day or two. I will report back with my results.

There is a git repo at http://public.kitware.com/gitweb?p=activizdotnet.git;a=summary for ActiViz...

I've got a (very occasionally updated) mirror of it on GitHub at https://github.com/dlrdave/activizdotnet

Why don't you guys fork the repo and make some git commits to share the code changes? Mailing zip files around just seems odd when using GitHub is so darn easy.

Subject: [vtkusers] Unstructured grid and coincident face rendering
Message-ID: <8D478341240222479E0DB361E050CB6A77EFDA@msy-emb04.int.cggveritas.com>

Dear All,

I need to render a 3D grid which is horizontally structured but vertically unstructured (a corner-point grid with vertical pillars).
This is made of columns on a regular grid, each column is made up of a possibly different number of voxels whose Z coordinates are different from the neighboring columns. Voxels are displaced only in Z, so their faces are always perfectly vertical and touch the adjacent columns.

I am using vtkUnstructuredGrid with VTK_VOXEL cells to represent this. In each column I have (Nz+1)*4 points to represent the voxel edges, so that 4 points are shared between two vertically adjacent voxels. I cannot share points laterally because the Z values are different.

My problem is that I get very bad surface rendering artifacts at the boundaries between two columns, probably because both faces are rendered (see attached screenshot).

The only way I could get the correct rendering is by using OSPray in Paraview, but it's very slow on my hardware.


-    Is vtkUnstructuredGrid the best way to do this?

-    Is there a way to hint VTK that some faces are partially coincident, as to avoid double rendering?


I can provide code samples or data if needed.


Thank you for your help,
Best Regards

Federico

Hello,


I'm trying to install VTK but I'm getting the following error


CMake Error at Common/Core/cmake_install.cmake:47 (file):
  file INSTALL cannot find
  "/home/VTK-6.3.0/VTKBuild/lib/libvtkCommonCore-6.3.so.1".
Call Stack (most recent call first):

These are the steps I followed

cd VTKBuild

cmake ..

make

make install


Can anyone point me to what might be going wrong, thanks!

Subject: [vtkusers] In Python,
 is it possible to use class methods with array pointer inputs ?
Message-ID: <CAEhu9hDUb_tEzaFSwJMHd6fOtJ0=UdRqwTH8=+W=xWt0SLc=Aw@mail.gmail.com>

Hello all,

I was wondering if there was any way to use class methods that have array
pointer inputs in Python.  For example, I was looking at the
vtkPolygon.PointInPolygon
<http://www.vtk.org/doc/nightly/html/classvtkPolygon.html#a02bd9f9ae98053a1923a0231aea12d09>
() method, which takes an array pointer specifying the points.  This C++
example <http://www.vtk.org/Wiki/VTK/Examples/Cxx/Utilities/PointInPolygon>
suggests getting the pointer by using a vtkPoints->GetVoidPointer() method,
but that doesn't seem to yield anything usable in Python.

Thanks,
Evan Kao

Subject: [vtkusers] Subdivided surface with non-subdivided edges (z
	fighting)
Message-ID: <CAFuWFr+CNWLYDgSt5comAVQ9VzM5d5FJwYdofHf4iEeK81L=Yg@mail.gmail.com>

Hi Greg, I had a similar problem some weeks ago. I wanted to show a refined
surface along with its original (before refining) edges. I had the same
fighting you mention between the original edges and the subdivided
surfaces. The method

m_wireMapper->SetResolveCoincidentTopologyToPolygonOffset()

solved my problem (here m_wireMapper is the vtkPolyDataMapper associated to
the non-refined wireframe represention of my object).
The outer edges of the wireframe mesh had to be coincident with the refined
surface mesh, so I could not use filter that modified very much the points?
coordinates. For example, vtkButterflySubdivisionFilter couldn?t be used. I
ended up using vtkSmoothPolydata filter for the solid surface, tuning its
parameters in order to minimize coordinates translations.


Hope this help

     Luca



>>Approach 3:

>>I extracted the edges from the original polygons, and tried drawing them
together with the subdivided polygons (where the subdivided polygon edge
visibility is off).  This is resulted in what I was after, except there's z
fighting between the original edges and the subdivided surfaces.  I read
about the various ResoveCoincidentTopology options, but those appear to be
for a polygon with it's own edges, not a polygon with some other edges.  I
played with them anyway, just in case, but didn't see anything promising.

Hi Evan,

If you are using VTK 6.1 or later, you should be able to use that method
from Python.  When a method asks for a pointer to int, float, double, etc.,
pass a Python container.  A python list is usually a good choice.

The best way to check if a method is available is with the Python help()
function:

help(vtk.vtkPolygon.PointInPolygon)

Help on built-in function PointInPolygon:

PointInPolygon(...)
    V.PointInPolygon([float, float, float], int, [float, ...], [float,
         float, float, float, float, float], [float, float, float])
        -> int
    C++: static int PointInPolygon(double x[3], int numPts,
        double *pts, double bounds[6], double n[3])

    Determine whether point is inside polygon. Function uses
    ray-casting to determine if point is inside polygon. Works for
    arbitrary polygon shape (e.g., non-convex). Returns 0 if point is
    not in polygon; 1 if it is. Can also return -1 to indicate
    degenerate polygon.

I've been able to successfully build Activiz 6.2 (both x86 and x64) thanks
to all of the knowledge in this thread and the files provided by Mark.

I'm wondering if anyone has been able to successfully build Activiz 6.2 (or

references to the vtK...OpenGL2 libraries in the Activiz CMake, but I have
yet to be able to do that successfully.

Thanks,

Hi all,
I'm doing simple visualization of data on rectangular grid by creating
vtkpolydata from single vtktrianglestrip and when running the application in
linux on intel hd graphics there is serious problem with z-fighting where
the parts that should be far away are overlapping parts that are near the
camera. This doesn't happen when running on windows (intel or nvidia) or on
linux with nvidia
here you can see the problem, the camera angle is still the same
http://tesla.math.sk/intel1.jpg <http://tesla.math.sk/intel1.jpg>  
http://tesla.math.sk/nvidia1.jpg <http://tesla.math.sk/nvidia1.jpg>  
another angle
http://tesla.math.sk/intel2.jpg <http://tesla.math.sk/intel2.jpg>  
http://tesla.math.sk/nvidia2.jpg <http://tesla.math.sk/nvidia2.jpg>  
this happens on vtk 7.0 and also on vtk 7.1 from git
tested hardware is intel hd graphics on haswell, and ivy bridge (mesa 11.2
and 12.0 with opengl 3.3) and on broadwell with mesa 12.0 with opengl 4.4
Is this a known issue or am I doing something wrong?

VTK algorithms run on the CPU. Rendering is done on the CPU or the graphics
card depending on your driver.
You may want to look a VTKM for an emerging technology for accelerating
computation and visualization using parallel hardware on your machine (GPU
or CPU)

Hope this helps,

Hi all,

from VTK's clip cow example, I have seen that it is possible to 
intersect two poly data objects and retrieve the union etc for specific 
coloring. Is this also possible with images of type vtkImageMapper3D? I 
guess for that purpose I would have to convert vtkImageMapper3D somehow 
to a vtkPolyData object, but I am not sure how this is possible by 
keeping the texture information etc.

Any idea?

Thanks,

Like Dan said, your graphics driver will (likely) decide to render on
your GPU. You should not need to recompile VTK.

HTH,

Subject: [vtkusers] Import time in Python
Message-ID: <CAEf70bwq3dYaTXo2r8p60Pc1M9sRWkYWFNfNyvnTV7Egri2fuw@mail.gmail.com>

Hello,

     I have recently installed VTK 7.0 to be used via Python 2.7 using the
excellent resources from Christoph Gohlke (http://www.lfd.uci.edu/~
gohlke/pythonlibs/). I have a considerably powerful machine at work - 96 GB
RAM, 8 cores, 64 bit Windows 7 Enterprise. However, executing the simple
command below:

import vtk

takes more than 7 seconds on this machine. I understand that there are
quite a few modules to import in the VTK hierarchy, but I was not expecting
such a dramatically slow operation. I also understand that this may not be
the perfect forum to post such a question, but maybe someone else has
encountered a similar behavior and he/she has some explanation for it.

Any suggestion is more than welcome, thank you in advance. I paste below
the results of profiling the simple import statement using the Python
profiler in this way:

python -m cProfile test_import_vtk.py


Andrea.

Subject: [vtkusers] VTK install error cannot find libvtkCommonCore-6.3.so.1


Hello,


I'm trying to install VTK but I'm getting the following error


CMake Error at Common/Core/cmake_install.cmake:47 (file):
  file INSTALL cannot find
  "/home/VTK-6.3.0/VTKBuild/lib/libvtkCommonCore-6.3.so.1".
Call Stack (most recent call first):
  cmake_install.cmake:100 (include)


These are the steps I followed

cd VTKBuild

cmake ..

make

make install


Can anyone point me to what might be going wrong, thanks!

@Matias Thank you for sharing the code. However, after successfulling
CMake-ing the project, the compilation of Activiz fails. There are a few
errors, but this seems to be the root cause (occurs in every project):

Error 2219 fatal error LNK1104: cannot open file
'vtkRenderingVolumeOpenGL.lib'

When I view the Linker > Input for one of those projects, I see:

...
D:\dev\sandbox\Activiz\VTK-6.2.0\bin-x64-opengl2\lib\Debug\vtkRenderingFreeType-6.2.lib
D:\dev\sandbox\Activiz\VTK-6.2.0\bin-x64-opengl2\lib\Debug\vtkInteractionStyle-6.2.lib
vtkRenderingVolumeOpenGL.lib
vtkRenderingContextOpenGL.lib
D:\dev\sandbox\Activiz\VTK-6.2.0\bin-x64-opengl2\lib\Debug\vtkRenderingContext2D-6.2.lib
D:\dev\sandbox\Activiz\VTK-6.2.0\bin-x64-opengl2\lib\Debug\vtkViewsCore-6.2.lib
...

I think it should be looking for vtkRenderingVolumeOpenGL2-6.2.lib
and vtkRenderingContextOpenGL2-6.2.lib instead, but I'm not sure how to
modify the build to make that happen. Any ideas?

@DavidCole Thanks. I forked that repo and if I get the Activiz 6.3 OpenGL2
build working, I will share the repo with the list

@Lui See my response to DavidCole, but I don't think anyone has gotten
Activiz working with VTK 7.0

Zamir, that .lib should be in your VTK 6.3 lib directory:
example:
C:\VTK-6.3.0_Buildx64\lib\Release

I have the .lib file you reference in that directory
(vtkRenderingVolumeOpenGL-6.3.lib)

I have the .lib file, but the problem is that the CMake is not generating
the correct reference to that lib. In the Linker > Input > Additional
Dependencies for a given project, it has a line that says:

vtkRenderingVolumeOpenGL.lib

where I believe it should really say something like:

D:\dev\sandbox\Activiz\VTK-6.2.0\bin-x64-opengl2\lib\Debug\vtkRenderingFreeType-6.2.lib
D:\dev\sandbox\Activiz\VTK-6.2.0\bin-x64-opengl2\lib\Debug\
vtkRenderingVolumeOpenGL2-6.2.lib

So it seems to be looking for the wrong version/name of the library and
also not in the correct location (possibly the two are related). When you
CMake that code, what does the Linker > Input > AdditionalDependencies for
a given *.Umanaged project look like for you?

If you can push a commit (or series of commits) to your fork, and
point me to it, I can take a look to see if I can help you through the
errors you're getting.

https://github.com/dlrdave/activizdotnet/commit/dae2417bdcc6bb517507ec4dc199e5443f5b229b?w=0#diff-af3b638bc2a3e6c650974192a53c7291R1050

contains the target_link_libraries command which should pull in the
necessary VTK unmanaged libraries to link to. If you are using the
OpenGL2 backend, you'll have to update the list of libraries in that
command appropriately.

I can't build it myself at the moment because I don't have access to
an old VS 2008 install right now. If this doesn't get you past this
error, I'll see if I can scrounge up access to a system like that this
weekend.


HTH,

You can even try just eliminating that line, and see what errors you

Eliminating the line didn't work. I added the modules that I thought were

made to my fork.

Thanks.

Hi,

It looks like this crash has been fixed in the current development
version of VTK. Your best bet is to build VTK from the master branch
in git.

HTH,
Cory

Hi Cory,

Thanks for your reply. I got the updated files and built again. It works
now.

It looks like this fix is not including in VTK 7.0.

I am using C++ with VTK7.0+Qt5.6 to build a application, when I use
QVTKWidget to render two vtkRenderWindow there come up a crash in runtime, I
simply use SetRenderWindow function to swith the two render window I
created, the error message:

Subject: [vtkusers] Import time in Python

YMMV, but on my ancient 2009 MacBook Pro, 2 cores, 2.53GHz, 4GB RAM, here
is the time to execute "import vtk":

$ time bin/vtkpython import_vtk.py
real 0m1.851s
user 0m0.640s
sys 0m0.448s

And on the second try (when the libs are in disk cache):

$ time bin/vtkpython import_vtk.py
real 0m0.612s
user 0m0.485s
sys 0m0.120s

So if my system takes 0.6s to import VTK, while yours takes 7s, that
suggests that something funny is going on. Does anyone else want to chime
in with their experience with loading VTK into Python?

Subject: [vtkusers] Crashed when I used a QVTKWidget to render two
 vtkRenderWindow in turn

If you use QVTKWidget, it is recommended to make two QVTKWidget s. 
You can show and hide each widget in QT very easily.
You don't need to switch two RenderWindow in on Widget with pain.

This was VTK 7.0.0 on a four core i7-4600U CPU @ 2.10GHz running Ubuntu
16.04. But my VTK might not be as extensive as yours, it was built like
this: https://launchpad.net/~elvstone/+archive/ubuntu/vtk7

So 7 seconds looks strange to me too.

Subject: [vtkusers] Import time in Python

Hi Andrea,

In my experience this is not uncommon on (modern) Windows computers if 
many installed applications have added their paths to the system path in 
front of the VTK DLLs path. Windows will test many directories searching 
for the DLLs it needs to load.

Typing "SET" from command line should show you where VTK is in the path. 
Windows adds the user path at the end of the system path, so if VTK was 
manually added to the user path, it might be likely at the very end of a 
long list of other paths.

The utility Process Monitor 
(https://technet.microsoft.com/en-us/sysinternals/bb896645) can also be 
used to see all the tests/searches the system will perform during 
"import vtk"

I hope this might help,

Best Regards,

Andrea

Thank you so very much for this suggestion: I have added the VTK DLL path
in front of everything in my user PATH variable and now I get:

D:\MyProjects>python -m cProfile test_import.py
         101 function calls in 0.793 seconds


:-D :-D :-D

Subject: [vtkusers] Cyrillic symbols in Scalar bar
Message-ID: <DUB402-EAS19195DD4FDCC8A79DE72E66A8150@phx.gbl>

Hello,
I have a problem with the installation of the Cyrillic alphabet in the title bar of a scalar ParaView, which as I understand using vtkScalarBar, which in turn uses vtkTextProperty. 
Installing custom fonts in vtkTextProperty 

this->SetFontFamily(VTK_FONT_FILE);
this->SetFontFile("C:\\arial.ttf");

lead to nothing, Paraview or ceases to run, or fonts on what does not influence. What can be done to remedy the shortcomings of this?

Thanks,
Shagit Ziganshin

Great!

You are right. There are numerous bug fixes and enhancements since 7.0
has been release, including this one. It will be included in 7.1,
though.

Best,

Can you provide a bit more context for this:

> this->SetFontFamily(VTK_FONT_FILE);
> this->SetFontFile("C:\\arial.ttf");

Since you're using a 'this' pointer, it sounds like you're subclassing
vtkTextProperty? That should not be necessary. Try calling those
methods on the specific text property associated with the scalar bar's
title:

vtkScalarBarActor *scalarBar = ...;
scalarBar->GetTitleTextProperty()->SetFontFamily(...);
scalarBar->GetTitleTextProperty()->SetFontFile(...);

HTH,
Dave

Hi List,

well, I can confirm that there are some problems with VTK7.0.0 and (on 
my system) QT 5.7.0.

The problems occur when reparenting QVTKWidgets. I have written a small 
demo app, based on existing VTK examples, which shows the problem. It is 
attached to this e-mail.

When reparenting (swapping) the two QVTKWidgets, the console window says 
"QWidget::repaint: Recursive repaint detected", and an error window pops 
up with "Invalid Pixel format, no OpenGL support".

Obviously, for the attached demo app, there would be a solution without 
reparenting the windows - nevertheless, it seems like a bug and in 
another application, I need to reparent the widgets, which (due to this 
problem) forces me to keep using Qt 4.8.7, in which reparenting is 
working.

Anybody can confirm the problem and propose a solution / workaround?

Thanks,

      Sophonet

While we are at it, a few additional notes related to this.

It is better not to use the path environment variable (PATH) to specify DLL search paths and generally this method is not used for Windows applications. The simplest solution is to put all DLLs in the same directory as the executable file is . There are a few more complex alternative methods using delay-loaded libraries or manifests.

If you chose to add directories to PATH then you always have to _replace_ the old PATH or _prepend_ your directories, due to more important reasons than just loading time:

1. Other applications might have added directories to PATH that contains similar DLLs as you are looking for. Those similar DLLs may be loaded instead of yours if you add your directories to the end.

2. Long environment variables may be truncated. If you try to append your directories to the end then they might not be effectively added.

Applications usually do not need to load anything from the extra directories listed in PATH (since system, C runtime libraries, etc. are not found using PATH) and you can simply replace PATH with the list of directories your application needs to load DLLs from.

Always use a launcher to set application-specific environment variables (a batch file or a tool such as http://www.commontk.org/index.php/Tools:_Application_launcher).

Hi Sophonet,

It has been discussed here before that there are known issues with
QVTKWidget and Qt 5.X.  QVTKWidget is using the QWidget parent to get a
window and then directly using window system calls for your OS to get an
OpenGL context.  This is not the way Qt expects OpenGL-based widgets to act
(and Qt knows nothing about the fact that it is an OpenGL-based widget) and
so there are problems.  (Especially if you are using the new OpenGL2
rendering backend)  There are a few ideas floating around for how to do
this right with Qt 5.X, but to my knowledge no one has actually tackled
this and created a VTK widget that subclasses Qt's new QOpenGLWidget and
deals with all the corner cases needed for VTK rendering.  Search the
archives of this mailing list for QOpenGLWidget (or QVTKWidget) and you
should find the threads where this was discussed.  I think there were a few
workarounds discussed on those...

Sorry this isn't a more helpful response,
Shawn

Hi, 
I have the task of using Cyrillic characters in vtk/paraview and faced with the problem that vtkVectorText does not accept characters other than English. The solution of this problem I believe lies in the Filters/Sources/vtkTextSource.cxx in array vtkfont_bits. Prompt what function it performs an array and how it is generated?

Thanks,

vtkVectorText only supports a very limited set of fonts and
characters. I'm not sure how the polydata it uses was generated.

I'd recommend using vtkTextActor3D in place of vtkVectorText, unless
the polydata representations is actually needed for some reason.

To elaborate a bit: vtkVectorText does not use the vtkfont_bits, as
far as I'm aware. See vtkVectorText.cxx -- it contains a large number
of static arrays containing polygon descriptions of the glyphs. If you
wish to extend it, you'll need to add more glyphs to this file.

Subject: [vtkusers] VTU Compressed base64 Data
Message-ID: <BAY405-EAS270038F893E1739626B0CF0C8160@phx.gbl>

Hi,

I have a VTU (unstructured grid) file that I?d like to parse myself. 

The header is as follows:
<VTKFile type='UnstructuredGrid' version='0.1' byte_order='LittleEndian' compressor='vtkZLibDataCompressor'>

And the AppendedData section looks like this:
<AppendedData encoding='base64'>
_AQAAAPD8AwDw/AMAA7wBAA==eNpcfXtYzE/U?
</AppendedData>

Running the appended data (excluding the first underscore) directly through a base64 decoder doesn?t appear to work. Running it through zlib uncompression doesn?t work either (invalid compressed data). So, I?m not sure where to start with this.

Any extra information about how to decompress and decode this appended data would be very helpful.

Regards,
Davis

Message-ID: <CAJiVSP6zTHhyYuTAguFeod=LtVFOmvTjo2i=MLi7T=ocwSbF3w@mail.gmail.com>

Hi VTK'ians,

I have python code that calls VTK C++ code. To compile the C++ code with
setup.py I need to know where the VTK libraries are installed. This
information is usually collected by cmake when using find_package(VTK) and
stored in the VTK_LIBRARIES, VTK_INCLUDES_DIRS and VTK_RUNTIME_LIBRARY_DIRS
variables.

Does anyone know whether it is possible to extract VTK_LIBRARIES,
VTK_INCLUDES_DIRS and VTK_RUNTIME_LIBRARY_DIRS or some equivalent
information from the python vtk module?

Thanks in advance!

I'm not sure about vtkfont_bits, I've never had to use it before.

And no, vtkVectorText cannot use characters outside of ASCII codepoints 33-126.

vtkTextActor3D can use any characters desired when supplied with a
vtkTextProperty that has FontFamily=VTK_FONT_FILE and FontFile set to
a font file with the desired characters. See
Rendering/FreeType/TestFreeTypeTextMapperNoMath.cxx:

  // UTF-8 freetype handling:
  vtkNew<vtkTextMapper> mapper10;
  vtkNew<vtkActor2D> actor10;
  actor10->SetMapper(mapper10.GetPointer());
  mapper10->GetTextProperty()->SetFontFile(uncodeFontFile.c_str());
  mapper10->GetTextProperty()->SetFontFamily(VTK_FONT_FILE);
  mapper10->GetTextProperty()->SetJustificationToCentered();
  mapper10->GetTextProperty()->SetVerticalJustificationToCentered();
  mapper10->GetTextProperty()->SetFontSize(18);
  mapper10->GetTextProperty()->SetColor(0.0, 1.0, 0.7);
  mapper10->SetInput("UTF-8 FreeType:
\xce\xa8\xd2\x94\xd2\x96\xd1\x84\xd2\xbe");
  actor10->SetPosition(300, 110);

That uses a vtkTextMapper, but the underlying font rendering uses the
same backend as vtkTextActor3D, and renders the non-english characters
in the UTF-8 string set via SetInput (see attached).

To add: vtkTextMapper, vtkTextActor, and vtkTextActor3D all share the
same rendering engine, and support the most functionality (including
non-english characters when supplied with an appropriate font file).
Any other text objects likely do not.

Subject: [vtkusers] Black plane when using vtkPlaneWidget with QVTKWidget
Message-ID: <CAFuWFrLS8DaArgKNmWO+WYGpzqau=6-YdFLP+pCA7M5SxcdLxQ@mail.gmail.com>

Hi everybody,
I would like to know if there is some special issue in using vtkPlaneWidget
with QVTKWidget. I have tested two identical codes, one using the standard
vtkRenderWindowInteractor outside a Qt environment, the other using
QVTKWidget. In both cases, I probe my dataset using vtkProbeFilter.
In the second case, I invoke the method vtkPlaneWidget::SetInteractor()
passing QVTKWidget::GetInteractor() as argument. The problem is that the
probing plane is not displayed. I see vtkPlaneWidget's  manipulators, I
rotate the widget etc, but the plane used to probe my data is shown in
black. The same application yelds a normal behavior when using
vtkRenderWindowInteractor.
What is the problem? I know that the call QVTKWidget::GetInteractor()
returns a QVTKInteractor object (which inherits vtkRenderWindowInteractor).
Do I have to give some special treatment to the vtkPlaneWidget in this case?

Many thanks for your help

              Luca

Subject: [vtkusers] Arrays and double arrays of VTK pointers
Message-ID: <57B75329.1020309@howard.edu>

Hi all,
I'm using VTK for some topological computation on surfaces and I need to 
use arrays and double arrays (matrices) of pointers of VTK objects. I 
read similar questions on this ML in the past years but no very 
satisfying (for me) answer.
With some effort I did find a way to do that but I know very little C++ 
and so possibly my way is unsafe and might cause some problem I cannot 
foresee now, so I'd be very glad if some of you more C++ knowledgeable 
could give a look to the code below and let me know if it's "safe":

<--- Example: 1-dim array of N pointers to vtkPolyData

vtkPolyData *p[N];
  for( int i=0; i<N; i++ )
     p[i] = vtkPolyData::New()

---------------->

<--- Example: 2-dim array of NxM pointers to vtkPolyData

vtkPolyData ***p = new vtkPolyData** [N];
for( int i=0; i<N; i++ ){
    p[i] = new vtkPolyData* [M];
    for( int j=0; j<M; j++ )
        p[i][j] = vtkPolyData::New();
}

---------------->

Thanks,
  Roberto De Leo

Hi,

For what it is worth, Slicer MacOSX build machine is still running  10.6.8,
we will soon transition to machine with 10.11

In the mean time, we reverted "Increase VTK OS X minimum check from 10.6.0
to 10.6.8" on the Slicer/VTK fork.

See https://github.com/Slicer/VTK/commits/slicer-v7.1.0-2016-07-06-b824d94

Hi :)
 
I want to run VTK at MFC.
 
So I find an example about SimpleMFC on VTK examples. 
 
But, It didn't build on my computer.
 
I use VTK 7.0.0 Version, and VS 2015.
 
I converted 'VTK setup file' by Cmake, and I set 'Visual Studio 14 2015'
 
I couldn't find MFC example using VTK 7.0.0 .
 
If someone use MFC using VTK7.0.0, please help me about that. Thank you

Hi all,
during moving from vtk 6.2 to vtk 7 (with enabled OpenGL2 backend 
rendering) we found serious bug in vtkDepthSortPolyData filter. There is a 
problem with generating of output vtkPolyData object. There are usage of 
wrong sizes for vtkCellArray for Vert, Lines, Polys,... Instead of real 
size the allocated size is used. Later in the rendering request 
uninitialised cell ids are used and rendering can crash.
I changed the code like this and it works now. Should be good to fix it 
also in VTK7 source code repository.

int vtkDepthSortPolyData::RequestData(
    vtkInformation *vtkNotUsed(request),
    vtkInformationVector **inputVector,
    vtkInformationVector *outputVector)
{
.
.
.
    vtkIdType *pOutputPolys = NULL;
    if (nPolys)
    {
        vtkCellArray *outputPolyCells = vtkCellArray::New();
        outputPolyCells->SetNumberOfCells(nPolys);
        output->SetPolys(outputPolyCells);
        outputPolyCells->Delete();
        vtkIdTypeArray *outputPolys = outputPolyCells->GetData();
-        outputPolys->SetNumberOfTuples(input->GetPolys()->GetSize());
+ 
outputPolys->SetNumberOfTuples(input->GetPolys()->GetNumberOfConnectivityEntries());
        pOutputPolys = outputPolys->GetPointer(0);
    }
.
.
.
}

Hello,

Maybe the problem comes from the polydata generation:
- When you use "SetNumberOfPoints" then you have to use the method
"SetPoint" instead of "InsertPoint".
- It is the same for "SetNumberOfIds".
- For the vtkCellArray I suggest you just replace "SetNumberOfCells" by
"Allocate".

I hope it helps.

Tristan

VS 2015 and VTK 7.0.0 were released fairly close to each other.  So I don't
remember if VTK 7.0.0 supports building with VS 2015.  I would recommend
either trying VS 2013 (which should build) or updating your VTK to build
from the master branch (which supports VS 2015).

Subject: [vtkusers] Picking specific vtkActor from vtkAssembly in Widget
Message-ID: <etPan.57bb00ef.4cac001e.12e@dkfz-heidelberg.de>

Hello everyone,
I am working on a custom widget. For that purpose I am also creating my own subclass of vtkWidgetRepresentation.
I looked at the implementation of vtkImplicitPlaneRepresentation as a reference. To find out which vtkActor of my widget has been selected, I used the code below. this->Picker is a vtkCellPicker, because that's what is used in the vtkImplicitPlaneRepresentation.cpp. Everything works, but once I detect the vtkAssembly (ToolPaletteAssembly) I don't know how to find the specific vtkActor of that vtkAssembly that has been picked.

I also tried switching the vtkCellPicker to vtkPropPicker, but ? in contrast to the working vtkCellPicker version ? it didn't yield a successful pick. (And I'm not sure why...).

Any pointers on how to get the specific actor of the assembly would be greatly appreciated.
Kind Regards,
Maurice Fahn

CODE:

customPlaneRepresentation::customPlaneRepresentation()
{
  // [...]
  this->Picker = vtkCellPicker::New();
  this->Picker->SetTolerance(0.005);
  this->Picker->AddPickList(this->OBJPlaneActor)
  this->Picker->AddPickList(this->ToolPaletteAssembly)
  // I also tried adding the actors that have been added to the assembly here as well with no difference regarding the picking
  this->Picker->PickFromListOn();
  // [...]
}

// [...]

int customPlaneRepresentation::ComputeInteractionState(int X, int Y, int vtkNotUsed(modify))
{
  // See if anything has been selected
  vtkAssemblyPath* path = this->GetAssemblyPath(X, Y, 0.0, this->Picker);

  if (path == NULL) // Not picking this widget
  {
    this->SetRepresentationState(customPlaneRepresentation::Outside);
    this->InteractionState = customPlaneRepresentation::Outside;
    return this->InteractionState;
  }

  // Depending on the interaction state (set by the widget) we modify
  // this state based on what is picked.
  if (this->InteractionState == customPlaneRepresentation::Moving)
  {
    vtkProp* prop = path->GetFirstNode()->GetViewProp();
    if (prop == this->OBJPlaneActor)
    {
        this->InteractionState = customPlaneRepresentation::MovingOrigin;
        this->SetRepresentationState(customPlaneRepresentation::MovingOrigin);
    }
    else
    {
      this->InteractionState = customPlaneRepresentation::Outside;
      this->SetRepresentationState(customPlaneRepresentation::Outside);
    }
  }
  else if (this->InteractionState == customPlaneRepresentation::ToolPalette)
  {
    vtkProp* prop = path->GetFirstNode()->GetViewProp();

    // Here it only detects ToolPaletteAssembly, never any of the actors that are part of ToolPaletteAssembly
    std::cout << "Picked: " << prop << std::endl;
    if (prop == this->ToolPaletteAssembly)
    {
      // How do I get the specifc actor of ToolPaletteAssembly that was picked?
    }
    else
    {
      this->InteractionState = customPlaneRepresentation::Outside;
      this->SetRepresentationState(customPlaneRepresentation::Outside);
    }
  }
  else
  {
    this->InteractionState = customPlaneRepresentation::Outside;
  }

  return this->InteractionState;
}

This looks good. Just be sure to have a similar loop somewhere that
calls p[i]->Delete() to clean these up when you're done using them.

I think you'd be better off with something like

vtkPolyData *p[N][M];
  for (... i to N ...)
    for (...j to M...)
      p[i][j] = vtkPolyData::New();

This way you don't have to deal with allocating/freeing the N arrays
of size M, and you'll actually get a contiguous block of vtkPolyData*
pointers. (The code you posted actually allocates an array of N
pointers to non-contiguous arrays of vtkPolyData*[M], rather than a
single block of NxM vtkPolyData*).

HTH,
Dave

I would use vtkSmartPointer or vtkNew so that you don't have to worry about
deleting them in a similar loop later.  vtkNew has the advantage that you
don't even have to write the allocation loop, but you have to call Get() to
pass it as a pointer to another function.

Like this:
  vtkSmartPointer<vtkPolyData> p[N][M];
  for (... i to N ...)
    for (... j to M ...)
      p[i][j] = vtkSmartPointer<vtkPolyData>::New();

or:
  vtkNew<vtkPolyData> p[N][M];  // vtkNew's constructor does the
allocation, so no need for an allocation loop

OK, I'll hold off merging the change in VTK until you switch.  What's your ETA on that upgrade?

I'm curious: are you still on 10.6 for some reason beyond "it works, and we're busy"? :)

Agreed, thanks for pointing that out -- I personally go for vtkNew
whenever possible just because it's so much easier to use. The only
reason to bother with manually allocating the objects is if you really
just need the raw pointers in the arrays for some reason (I'm not sure
if that was a requirement here, but I wanted to point that out just in
case).

Good catch -- looks like a slip up because VTK's APIs are unconventional
(GetSize() returns capacity, not number of elements as one would expect).
I'll make a merge request for this.

Thanks!

Interestin. I just did a
git grep GetSize
and looked for its use for Polys.

It occurs many times, but mainly in Allocate() statements. This means we
could be over allocating althought I expect that must Polys have been
Squeezed.

I did find these uses:
IO/Xdmf2/vtkXdmfWriter.cxx:        vtkIdType sizev =
pd->GetVerts()->GetSize();
IO/Xdmf2/vtkXdmfWriter.cxx:        vtkIdType sizel =
pd->GetLines()->GetSize();
IO/Xdmf2/vtkXdmfWriter.cxx:        vtkIdType sizep =
pd->GetPolys()->GetSize();
IO/Xdmf2/vtkXdmfWriter.cxx:        vtkIdType sizes =
pd->GetStrips()->GetSize();

Which look like they could be errors.

Actually the results are used for allocation, so these are OK.

Shouldn't we deprecate this class then?  As I understand it, newer classes replace it, correct?

Hi, again.

I got the following advice directly from Jason:

I?ve gotten decent results using approach 3 as described below (although in
> VTK 7) with the following options:
>
>    vtkPolyDataMapper::SetResolveCoincidentTopologyToPolygonOffset();
>
>  vtkPolyDataMapper::SetResolveCoincidentTopologyPolygonOffsetParameters(0,0);
>
>  vtkPolyDataMapper::SetResolveCoincidentTopologyLineOffsetParameters(-2,.2);


As far as I can tell, SetResolveCoincidentTopologyLineOffsetParameters is
not available before vtk-7. I tried building vtk-7, but that turned out to
be problematic...

The root of that problem is that I have to support an industry that still
commonly uses RHEL5 machines, which means I'm stuck with the GCC-4.1.2 that
comes with RHEL5.  But vtk-7 requires at least GCC-4.2.  I looked around a
bit online, and didn't see a technical reason why vtk-7 *had* to have
gcc-4.2, so I disabled the two tests and built it with gcc-4.1, with no
compile/link errors.

Sadly, at runtime, I got a complaint about the mesa version, and a
segfault.   I tried building the requested version of mesa, but that turned
out to be problematic. I had gotten a previous version to work by rewriting
small parts of mesa's install scripts to not use the python ternary
operator.  But the requested version had a lot of other problems and some
new dependencies.

So approach 3 is out.  Does anyone see a way to make approach 1 (vtk edge
flags), or approach 2 ("surface with edges", but without the surface), or
something else work?

My original problem is to show "surface with edges" where the "edges" are
from an original set of geometry, but the "surface" consists of subdivided
geometry.   For example, if the original geometry was just one triangle,
I'd introduce 4 new vertices (one for the triangle center, and 1 for each
edge midpoint).  The subdivided geometry would be 3 quads using those
vertices.   So I need both the original edges and thet new texture mapped
quads (without z fighting).

Thanks in advance for any help.

Greg

Subject: [vtkusers] How to tune the line with of vtkProperty2D
Message-ID: <340a03a8.4.156b4f33d88.Coremail.tjlp@netease.com>

Hi,

I use vtkAngleWidget to measure angle. I want to tune the line width of the angle leaders and arc. Below is my C# code:

            m_angleWidget = vtkAngleWidget.New();
            m_angleWidget.SetInteractor(m_renderWin.GetInteractor());
            m_angleWidget.PlacePointEvt += new vtkObject.vtkObjectEventHandler(AngleWidget_PlacePointEvt);
            m_angleRep = vtkAngleRepresentation2D.New();
            m_angleRep.GetRay1().GetProperty().SetColor(0.0, 1.0, 0.0);
            m_angleRep.GetRay1().GetProperty().SetLineWidth(8.0f);
            m_angleRep.GetRay2().GetProperty().SetColor(0.0, 1.0, 0.0);
            m_angleRep.GetRay2().GetProperty().SetLineWidth(8.0f);
            m_angleRep.GetArc().GetProperty().SetColor(0.0, 1.0, 0.0);
            m_angleRep.GetArc().GetProperty().SetLineWidth(8.0f);
            m_angleRep.GetArc().GetLabelTextProperty().SetColor(0.0, 0.0, 1.0);
            m_angleWidget.SetRepresentation(m_angleRep);

If I call SetLineWidth with 5.0f, 6.0f, 7.0f and 7.5f, I get the same effect as 1.jpg; if I call SetLineWidth with 8.0f, the effect is as 2.jpg. For me, the line in 1.jpg is too slim, the line in 2.jpg is too wide, how to tune it?

Thanks

Yes and no. There are better ways to render text, but vtkVectorText
produces a polydata representation of the text (each glyph is actually
drawn), while the others render a textured quad with a image of the
rendered string. This may be useful if there's a need to transform the
polydata somehow for some reason or something, so there is some unique
functionality there. Plus the usual anti-deprecation arguments about
legacy client code and customers, etc.

It sounds like an openGL driver issue.  What version of VTK are you using
and is it built with the OPenGL1 or OpenGL2 backend? What GPU is on the
system you are using?

Assuming you are using a recent VTK with OpenGL2 backend my guess is that
your hardware is saying it can draw wide lines up to 7.5 pixels (though it
seems not to), beyond that VTK is having to render the wide lines itself.
That would be my guess. If you are using a recent VTK with the OPenGL2
backend you can test this by modifying the HaveWideLines method in
Rendering/OpenGL2/vtgkOpenGLPolyDataMapper2D.cxx

change

    return !(renWin &&
      renWin->GetMaximumHardwareLineWidth() >=
actor->GetProperty()->GetLineWidth());

to

    return true;

This sounds like a driver issue. I suppose you could try setting the
following environment variable

GALLIUM_DRIVER=llvmpipe

to switch to software rendering and see if the problem goes away.  If
nvidia and mesa llvmpipe both work on your linux system then I would really
suspect the intel linux driver.

If you could use VTK 7+ Your approach 3 would be the best way to do it. Be
aware

 vtkPolyDataMapper::SetResolveCoincidentTopologyLineOffsetParameters(-2,.2);

In calls like that the two parameters should have the same sign for best
results.

Using an old version of VTK I think you can do option 3 but with the
following calls

vtkMapper::SetResolveCoincidentTopologyToPolygonOffset();
vtkMapper::SetResolveCoincidentTopologyPolygonOffsetParameters(-2.0,-5.0);

play with the -2.0 and -10.0 to get the best results.

Thanks
Ken

Subject: [vtkusers] vtkPlaneWIdget applied to object with a high ZScale
	factor
Message-ID: <CAFuWFrLcSWXoQsVM4G7mebUDz0XpmXE5hOHb9CR805_i4sxgrg@mail.gmail.com>

Hi everybody,

I am trying to probe a vtkStructuredGrid using vtkPlaneWidget. My grid is
very thin and to obtain a good visualization, I need to apply a ZScaling of
300, using vtkActor::SetScale(), executed, for example, on an actor
corresponding to the grid outline. The problem is that when I try to issue
the probing using vtkPLaneWidget, my plane gets none of the celldata
contained in the StructuredGrid. Even if I manually resize the plane
(remember that I am scaling my data's actor by a factor of 300) and it is
visualized as cutting my grid, I get no data inside my probing plane. To
initially position the plane I use the PlaceWidget() method.
I think this is a scaling issue because when I modify my grid's Z
coordinates (multiplying by 300), the plane correctly shows the results
(data) of the probing.
So I thought I had to provide this ZScaling factor to the widget, but I
found no explicit mention about this in the class documentation.
I tried  the SetProp3D  method, passing my scaled actor as argument. In
this case, the plane is correctly shown as resized but again with no data.
In the geological application I am writing it is very common to use a large
ZScale factor due to the regional nature of the data.
How can I perform the correct probing using a ZScale factor? Is
coordinates' transformation the only way to get the correct result?

Thank you for any help

        Luca

Why not Cocoa? VTK over X11 is strongly discouraged on Mac.

Hi James,

Assuming that you have installed xquartz and that you have all the X11
headers and libraries in /opt/X11, you have to tell cmake to use the OpenGL
that comes with X11:

OPENGL_INCLUDE_DIR:PATH=/opt/X11/include
OPENGL_gl_LIBRARY:FILEPATH=/opt/X11/lib/libGL.dylib
OPENGL_glu_LIBRARY:FILEPATH=/opt/X11/lib/libGLU.dylib

Otherwise VTK will link to the framework OpenGL, which doesn't include glx.

Even with the above, there are no guarantees that VTK will work with X11 on
OS X.  But it should at least get you past the link errors.

 - David

Hi, Ken,

What do you mean "your hardware is saying it can draw wide lines up to 7.5 pixels"? From my attachment, the effect of 8.0f is greatly wider than 7.5f. I am using VTK 7 with OpenGL2.


Thanks

It sounds like an openGL driver issue.  What version of VTK are you using and is it built with the OPenGL1 or OpenGL2 backend? What GPU is on the system you are using? 


Assuming you are using a recent VTK with OpenGL2 backend my guess is that your hardware is saying it can draw wide lines up to 7.5 pixels (though it seems not to), beyond that VTK is having to render the wide lines itself. That would be my guess. If you are using a recent VTK with the OPenGL2 backend you can test this by modifying the HaveWideLines method in Rendering/OpenGL2/vtgkOpenGLPolyDataMapper2D.cxx


change


    return !(renWin &&
      renWin->GetMaximumHardwareLineWidth() >= actor->GetProperty()->GetLineWidth());


to


    return true;

If I call SetLineWidth with 5.0f, 6.0f, 7.0f and 7.5f, I get the same effect as 1.jpg; if I call SetLineWidth with 8.0f, the effect is as 2.jpg. For me, the line in 1.jpg is too slim, the line in 2.jpg is too wide, how to tune it?

Thanks

            m_angleRep.GetRay1().GetProperty().SetColor(0.0, 1.0, 0.0);
            m_angleRep.GetRay1().GetProperty().SetLineWidth(8.0f);
            m_angleRep.GetRay2().GetProperty().SetColor(0.0, 1.0, 0.0);
            m_angleRep.GetRay2().GetProperty().SetLineWidth(8.0f);
            m_angleRep.GetArc().GetProperty().SetColor(0.0, 1.0, 0.0);
            m_angleRep.GetArc().GetProperty().SetLineWidth(8.0f);
            m_angleRep.GetArc().GetLabelTextProperty().SetColor(0.0, 0.0, 1.0);
            m_angleWidget.SetRepresentation(m_angleRep);

If I call SetLineWidth with 5.0f, 6.0f, 7.0f and 7.5f, I get the same effect as 1.jpg; if I call SetLineWidth with 8.0f, the effect is as 2.jpg. For me, the line in 1.jpg is too slim, the line in 2.jpg is too wide, how to tune it?

Thanks
Liu Peng

Subject: [vtkusers] free form user sketch on 3D mesh
Message-ID: <1472021885862-5739910.post@n5.nabble.com>

Hello, 

I have a 3D mesh (structured grid). I need to implement a technique to let
users sketech an area (an interest area) on the mesh (or grid), and in
result, a 3d interest area is highlighted. 
Previously, I had implemented the drag and drop selection for the 3D mesh
(which in result you have a solid highlighted rectangle area), and it works
fine. Now I need to change it to a free form sketch area. 

I don't know how to implement that free form sketch and use it to extract a
3d interest area our of a grid or mesh. Please help me with that.

Thanks,

Subject: [vtkusers] How does VTK measure surface distance on 3D model?
Message-ID: <60d71bda.b.156bb6064cf.Coremail.tjlp@netease.com>

Hi,

Does VTK have any class to measure the surface distance (not line distance) between points on 3D model?

Thanks

Your opengl driver tells VTK how wide of a line it can draw via something
like

      glGetFloatv(GL_ALIASED_LINE_WIDTH_RANGE,lineWidthRange);
      if (glGetError() == GL_NO_ERROR)
        {
        this->MaximumHardwareLineWidth = lineWidthRange[1];
        }

If your driver says it can handle lines up to 7.5 then VTK let's your
driver handle it. When you request a line greater than what your driver
says it can handle, VTK handles it itself. That is why you could see a
sudden discontinuity in line sizes. If your driver reports it can do wide
lines when in fact it doesn't you would see the behavior you described.
hence my suggestion on how to test for that.

I understand that, however the application we are supporting is
only ported to X11 / GTK. At some point we would like to port
over to native GUI, but resources are rather thin.

The software is called 'chips' and is part of the CIAO,
the Chandra x-ray telescope analysis software package.

These CGL calls are invalid for X11 OpenGL.  You'll have to modify your

usually does for Linux.

Let me know if you need any more information.

Subject: [vtkusers] Unstructured grid and coincident face rendering
Message-ID: <8D478341240222479E0DB361E050CB6A78FDEE@msy-emb04.int.cggveritas.com>

The problem is that the surface extraction filter marks all the vertical faces as external because they are all used by just one cell. This leads to all the other issues, including performance because everything is rendered even if inside.

I managed to solve the issue for my specific case by employing a StructuredGrid.
I create an extra column of degenerate cells with zero width at the interface between two columns and I add zero height cells at the bottom if columns have different cell counts.

This only works because my grid is horizontally structured.

I don't really like this and I still wonder if there is a general solution for adjacent cells with partially overlapping faces.

Any thoughts?

Thanks,
Federico

Subject: Unstructured grid and coincident face rendering

Dear All,

I need to render a 3D grid which is horizontally structured but vertically unstructured (a corner-point grid with vertical pillars).
This is made of columns on a regular grid, each column is made up of a possibly different number of voxels whose Z coordinates are different from the neighboring columns. Voxels are displaced only in Z, so their faces are always perfectly vertical and touch the adjacent columns.


  *-----*
/     /|
*-----* o-----o
|     |/     /|
|     o-----o |
|     |     | |
*-----*     | o
|     |     |/
|     o-----o
|     |/
*-----*


I am using vtkUnstructuredGrid with VTK_VOXEL cells to represent this. In each column I have (Nz+1)*4 points to represent the voxel edges, so that 4 points are shared between two vertically adjacent voxels. I cannot share points laterally because the Z values are different.

My problem is that I get very bad surface rendering artifacts at the boundaries between two columns, probably because both faces are rendered (see attached screenshot).

The only way I could get the correct rendering is by using OSPray in Paraview, but it's very slow on my hardware.


-    Is vtkUnstructuredGrid the best way to do this?

-    Is there a way to hint VTK that some faces are partially coincident, as to avoid double rendering?


I can provide code samples or data if needed.


Thank you for your help,
Best Regards

Federico

Here's a little hint:

In Rendering/OpenGL/CMakeLists.txt find the section labeled "#
Configuration for vtkOpenGLExtensionManager" change this:

elseif(APPLE)
  set(VTK_USE_APPLE_LOADER 1)
  set(VTK_USE_CORE_GRAPHICS 1)

to this:

elseif(APPLE AND NOT VTK_USE_X)
  set(VTK_USE_APPLE_LOADER 1)
  set(VTK_USE_CORE_GRAPHICS 1)

I don't know if that will work, because I haven't tested it, but it should
move you in the right direction.

 - David

Thanks. We need to modify VTK anyway for our project so
I doubt this will be an issue. I'll pass it in to the developers.

Subject: [vtkusers] How does VTK measure surface distance on 3D model?

The vtkDijkstraGraphGeodesicPath traces out the shortest path along cell
edges and is restricted to computing a path from one vertex to another
instead of from an arbitrary point to another arbitrary point, which may
not be what you want.

For true geodesic calculation on a surface, you can try the contribution in
this VTK Journal article:

Hi everybody,

is it possible to cut a StructuredGrid  containing CellData with a plane
and have the data mapped on the plane's polygons as CellData?
If this can be done, is there any example showing this feature?

   Many thanks in advance,

I made a few more tests:

the same problem happens with llvmpipe and with nvidia with nouveau driver

doesn?t happen on nvidia binary driver or in OS X with intel or nvidia or in windows with intel or nvidia

So maybe it?s a bug in mesa? Currently I?m using qt5 with qvtkwidget, I will try to create minimalistic example without qt to see if the problem is reproducible

This sounds like a driver issue. I suppose you could try setting the following environment variable

 

GALLIUM_DRIVER=llvmpipe

 

to switch to software rendering and see if the problem goes away.  If nvidia and mesa llvmpipe both work on your linux system then I would really suspect the intel linux driver.

Hi all,
I'm doing simple visualization of data on rectangular grid by creating

linux on intel hd graphics there is serious problem with z-fighting where
the parts that should be far away are overlapping parts that are near the
camera. This doesn't happen when running on windows (intel or nvidia) or on
linux with nvidia
here you can see the problem, the camera angle is still the same

another angle

http://tesla.math.sk/nvidia2.jpg <http://tesla.math.sk/nvidia2.jpg>
this happens on vtk 7.0 and also on vtk 7.1 from git
tested hardware is intel hd graphics on haswell, and ivy bridge (mesa 11.2
and 12.0 with opengl 3.3) and on broadwell with mesa 12.0 with opengl 4.4
Is this a known issue or am I doing something wrong?

Hi,


?
Given a poly data that represents a 3D model and a radius, isthere any way to retrieve a region (sphere?) where the point density is thehighest (i.e. the sphere with the given radius that contains the highest numberof points within itself)?


?
Thank you,

Ioana?

Hi everybody,
just continuing the topic of my last post, I have successfully cut my
vtkStructuredGrid using  vtkCutter and obtained the celldata at the cut
plane as I needed. Sorry for bothering the members of this list.
Now I have another dout, could I have used vtkClipDataSet instead of
vtkCutter?
What is the difference in the output?
Is there is no difference, which option is the fastest?

  Thank you,

Subject: [vtkusers] Multiple volumes rendering with
	vtkGPUVolumeRayCastMapper or similar
Message-ID: <DBF3444A-5F33-4387-9EC9-55B499D02201@gmail.com>

Dear all, 
we (a research team <http://plasma.desy.de/research/simulation_and_theory/index_eng.html> in DESY, Germany) are strongly interested in rendering multiple data volumes in the same view with VTK. 
We chose VTK for our 3D visualisation project on beam-plasma interactions due to its extended functionality and features, 
its open source character and because it is written in C++ with bindings for python.
However, we will require to show multiple volumes in the same view (representing the data of different particle species in our simulations).
We are currently using a vtkGPUVolumeRayCastMapper object for each data set, which is then connected to a vtkVolume. 
The different vtkVolume objects are then added to the vtkRenderer.
We have tried to use different vtkRenderer objects for the different vtkVolumes, 
but still only the first volume on the first vtkRenderer is displayed. 

Searching in the web, we have found the following (potential) solution:
https://github.com/bozorgi/VTKMultiVolumeRayCaster
which is published here:
http://www.ncbi.nlm.nih.gov/pubmed/24841148

It consists on new vtk classes to handle multiple volumes rendering.
As it might work well for our purposes, we would like to ask your opinion about this new classes.
Are you planning to incorporate something like this in the official VTK distribution soon?
If not, we will be interested in incorporating this new class into our personal VTK installation.
Then the question is: Will be the python bindings automatically generated for these new classes?

Thanks a lot for your support!

Best regards,
Alberto

I'm not sure what you mean by vtk2DActor, but it is possible to render
unicode text by configuring the vtkTextProperty's FontFamily to
VTK_FONT_FILE and setting FontFile to a font file that supports the
character you wish to use. The default fonts in VTK do not support
much if any unicode, so you'll need to provide a font file.

This approach will work for vtkTextActor, vtkTextActor3D, and vtkTextMapper.

Example: https://github.com/Kitware/VTK/blob/master/Rendering/FreeType/Testing/Cxx/TestFreeTypeTextMapperNoMath.cxx#L148-L159

ok, everything works fine without qvtkwidget, so the problem is somewhere there

I made a few more tests:

the same problem happens with llvmpipe and with nvidia with nouveau driver

doesn?t happen on nvidia binary driver or in OS X with intel or nvidia or in windows with intel or nvidia

So maybe it?s a bug in mesa? Currently I?m using qt5 with qvtkwidget, I will try to create minimalistic example without qt to see if the problem is reproducible

This sounds like a driver issue. I suppose you could try setting the following environment variable

 

GALLIUM_DRIVER=llvmpipe

 

to switch to software rendering and see if the problem goes away.  If nvidia and mesa llvmpipe both work on your linux system then I would really suspect the intel linux driver.

Hi all,
I'm doing simple visualization of data on rectangular grid by creating

linux on intel hd graphics there is serious problem with z-fighting where
the parts that should be far away are overlapping parts that are near the
camera. This doesn't happen when running on windows (intel or nvidia) or on
linux with nvidia
here you can see the problem, the camera angle is still the same

this happens on vtk 7.0 and also on vtk 7.1 from git
tested hardware is intel hd graphics on haswell, and ivy bridge (mesa 11.2
and 12.0 with opengl 3.3) and on broadwell with mesa 12.0 with opengl 4.4
Is this a known issue or am I doing something wrong?

I don't remember exactly, but I think I had the same problem. Should be
somewhere on this list I think.

I think it's possible to work around by manually setting the stencil buffer
size on the QGLFormat used by the widget.

On the bus at the moment so have limited ability to search.

Ah, that's good to know. I believe when I was having the problem, I was
working through Python, so was using QVTKRenderWindowInteractor (or maybe
my own similar class), which is yet another thing (QVTKWidget / QVTKWidget2
are not wrapped).

Glad it worked out anyway. Nowadays I'm using C++ and QVTKWidget2 too.

I am trying to build VTK with OSMesa instead of QT using Cmake 3.5.2 and
Windows 10.

 

I downloaded the source from http://www.mesa3d.org/download.html and
compiled it using SCons.

I followed the guide
http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D#Configuring_ParaV
iew_for_use_with_OSMesa and it generated just fine.

 

When I build Visual Studio complains about syntax errors:

I am using Visual Studio 2015 and I have no idea what typedef OSMesaContext
GLAPIENTRY (*OSMesaCreateContextAttribs_func)( const int *attribList,
OSMesaContext sharelist ); actually does, so I am at a loss as to what the
problem is.

The only other potential problem is the fact that I did not have the file
libosmesa.lib. I only had osmesa.lib. Not sure if that will cause a problem
or what the difference is.

 

Thank you for your help.

Yours,

Magnus Elden

Subject: [vtkusers] Help displaying Plane
Message-ID: <CAD3_OrXfrVc1bVZkSbcvRL-F3OfB45st7qVv-9UKkji60CTxsg@mail.gmail.com>

 Hello,

I am new to vtk and I want to be able to draw a plane. I have followed this
<http://www.vtk.org/Wiki/VTK/Examples/Cxx/GeometricObjects/Plane> tutorial
to be able to set a plane as a point and a normal. However, this only
produces a 1x1 plane (or at least that is what I think it does). I guess
that there is a way to actually display a plane that is different in size
because vtk is well done (but I have not been able to find it). How can I
change the size of the plane?

Thank you!!!

According to the vtkPlaneSource documentation, you aren?t really supposed to define the plane with the SetNormal function. You are supposed to define it with SetPoint1, SetPoint2 and SetCenter. Another popular way of making the plane you want is to start out with the default plane ? which is centered at the origin, perpendicular to the z axis, and has an x-direction measurement of 1, and a y-direction measurement of 1. You then use vtkTransform to make it the shape you want it to be.

I was going to give you a working example, but ran into something that I didn?t understand.
I thought this would make a plane that was 2 units in x, 1 unit in y, and had a center at (1, 0.5) - which seems to be what ParaView does with it ? however it seems to come out as a parallelogram?

import vtk

plane = vtk.vtkPlaneSource()
plane.SetPoint1(2.0, 0.0, 0.0)
plane.SetPoint2(0.0, 1.0, 0.0)
plane.SetCenter(0.0, 0.0, 0.0)
plane.Update()

mapper = vtk.vtkPolyDataMapper()
mapper.SetInputData(plane.GetOutput())

actor = vtk.vtkActor()
actor.SetMapper(mapper)

renderer = vtk.vtkRenderer()
renderer.AddActor(actor)

render_window = vtk.vtkRenderWindow()
render_window.AddRenderer(renderer)

render_window_interactor = vtk.vtkRenderWindowInteractor()
render_window_interactor.SetRenderWindow(render_window)

renderer.SetBackground(0.1, 0.3, 0.9)
render_window_interactor.Start()

Ok, I figured it out after going through the source code
<https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwi-88WI9t3OAhVCKx4KHaXuDpYQFggdMAA&url=https%3A%2F%2Fgithub.com%2FKitware%2FVTK%2Fblob%2Fmaster%2FFilters%2FSources%2FvtkPlaneSource.cxx&usg=AFQjCNF_rx55XLQfn1is2BVZGwEbVpstxQ&sig2=B-eed3UB3r37BP6ehFWkiA&bvm=bv.130731782,d.dmo&cad=rja>.
The SetPoint1 and SetPoint2 set the second point of the vector while the
first one is set by SetOrigin (by default origin [-0.5 -0.5 0] ). This
leads to the rhomboid because the two vectors of the parametric equation
 p=p0+v1*t+v2*s are computed as in v1 = point1 - origin and v2 = point2 -
origin.  So if you chose Point1 to be only in the X direction and point 2
to the Y (which in my mind is what should give a square) gives a rhomboid
because the director vectors of the plane are not perpendicular.

So, to define the plane I do:

// Add plane

vtkSmartPointer<vtkPlaneSource> planeSource =
vtkSmartPointer<vtkPlaneSource>::New();

// Set origin for computing the two director vectors

planeSource->SetOrigin(0,0,0);

// Set point for first director vector

planeSource->SetPoint1(x_size,0,0);

// Set point for second director vector

planeSource->SetPoint2(0,y_size,0);

// Set center

planeSource->SetCenter(5, 0.0, 0.0);

// Set normal

planeSource->SetNormal(0,0,1);


Hope this helps to anybody that might be in the same trouble.

Hi Alberto,

as you have noticed, multi-volume rendering is currently not supported in
the vtkGPUVolumeRayCastMapper.  If you are building VTK with OpenGL2
however, it supports independent components so (depending on your use case)
you might be able to render up to 4 volumes (one per component), provided
you can arrange them in a four component array (this has the limitation
that each component will need to have the same dimensions).  That said, we
are working on giving support for multiple volumes in the next VTK release.

With regards to the solution you mentioned (https://github.com/bozorgi/VTK
MultiVolumeRayCaster), you could use it temporarily if it would solve your
problem better than fitting the volumes as independent components.  It
seems to implement a similar approach as we would do (connecting various
inputs/ properties to the mapper) so it should not be extremely difficult
to migrate to the official implementation in the future.  I have not tried
it myself but please do let us know if you have any remarks once you try
it.  As far as I know, if the python bindings are not explicitly disabled
for these new classes then they should be also wrapped.

Regads,
?lvaro

I have to jump in and ask: I was under the impression that multiple volumes
was supported, as long as they don't intersect eachother in 3D space? But
you're saying it's not possible at all?

If so I'm in a bit of trouble myself, as I was planning on doing that soon
:(

In my case I have multiple volumes (coming from different readers) that I
want to render next to eachother (but not overlapping anywhere).

If that's really not possible, I'll have to rethink my pipeline and
redesign my custom reader to work with multiple files instead (and output a
single volume). The problem with this is that I might want to show a volume
that is larger than 2048 voxels in one dimension, which is not possible, at
least not on intel, due to GPU texture size limitations (see my semi-recent
thread about this). I had hoped that using multiple volumes would be a way
to get around this.

Thanks in advance,
Elvis

I found the mail by Aashish which led me to believe this was possible:

    http://public.kitware.com/pipermail/vtkusers/2016-February/094333.html

If it is actually possible, I have a question about the result I would get:
If I had multiple volumes in the same view (non-intersecting) and the
camera was positioned such that one of the volumes is in front of the other
relative to the camera. Would the obstructed voxels of the furthest volume
not be visible at all, or would I be able to see them "through" the nearest
volume?

I was actually wrong. I had a look at my code, and I'm using QVTKWidget
(not QVTKWidget2), and what I did to get around problems with Z-ordering
and also to get multisampling working reliably was this (from the
constructor of my QVTKWidget subclass):

    QSurfaceFormat surfaceFormat = windowHandle()->format();
    surfaceFormat.setSamples(8);
    surfaceFormat.setStencilBufferSize(8);
    windowHandle()->setFormat(surfaceFormat);

Hope that helps someone else using QVTKWidget.

Hi ?lvaro,

Thanks a lot for your prompt answer!
See my comments below. 

> as you have noticed, multi-volume rendering is currently not supported in the vtkGPUVolumeRayCastMapper.  If you are building VTK with OpenGL2 however, it supports independent components so (depending on your use case) you might be able to render up to 4 volumes (one per component), provided you can arrange them in a four component array (this has the limitation that each component will need to have the same dimensions).  That said, we are working on giving support for multiple volumes in the next VTK release.

It is great to read that you are working on this feature for future releases of VTK. 
I think that it will be very useful for many people. 
In the mean time I would like to try your proposed approach of defining multiple components in one volume. 
Let me ask you something:
If data1, data2, data3 are my three independent three-dimensional data arrays, should I merge them first in a four-dimensional array where the first index is the component index?

> With regards to the solution you mentioned (https://github.com/bozorgi/VTKMultiVolumeRayCaster <https://github.com/bozorgi/VTKMultiVolumeRayCaster>), you could use it temporarily if it would solve your problem better than fitting the volumes as independent components.  It seems to implement a similar approach as we would do (connecting various inputs/ properties to the mapper) so it should not be extremely difficult to migrate to the official implementation in the future.  I have not tried it myself but please do let us know if you have any remarks once you try it.  As far as I know, if the python bindings are not explicitly disabled for these new classes then they should be also wrapped.

Alright. However this solution is currently not useful to me since it was implemented for VTK 5 (I think) and it fails to compile against VTK 7. 
So I am temporarily stuck here. I?d like to try your approach with the multi-components?

Could you give an rough estimation of when multiple volumes rendering with vtkGPUVolumeRayCastMapper will be available in VTK?

Thanks a lot!

Regards,
Alberto

Indeed Elvis, to clarify the confusion, I was referring to overlapping
volumes in my last email. As mentioned in (
http://public.kitware.com/pipermail/vtkusers/2016-February/094333.html),
it is possible to add multiple vtkVolumes to a single vtkRenderer, this
would work if they are not overlapping.

>Would the obstructed voxels of the >furthest volume not be visible at all,
or >would I be able to see them "through" >the nearest volume?

You should see through (alpha blending is on during volume rendering).

Hi Albert,

Sounds like you figured it out.  Here is a clarification for future readers:

A vtkPlaneSource's output is always a parallelogram (square, rectangles and
rhombi are special cases of this). SetOrigin sets one corner of the plane.
SetPoint1 and SetPoint2 set the corners adjacent to that one.  All of these
points are in world coordinates not relative to each other.  The fourth
corner and the normal are computed based on the offsets to these two points
from the origin.

You should merge them in a three-dimensional array (each component being
dataN).  Checkout TestGPURayCastTwoComponentsIndependent, that could serve
you as an example.  Going back to your initial question though, as Elvis
pointed out, if your volumes are not overlapping you could create instead
several vtkVolumes (each with its own mapper), this should also work.

Could you give an rough estimation of when multiple volumes rendering

My best guess would be VTK 8.

My volumes are overlapping but they are defined in the same (regular) grid. 
So I need to use the multi-component trick. 
However I still do not understand the format?
Lets say that I have two 3D arrays data1 and data2 with identical number of components in each direction, i.e.  data1(Nx,Ny,Nz) and data2(Nx,Ny,Nz).
Should merge them into another array which would look like this: 
data(2 * Nx, Ny, Nz) 
with data(i,j,k) = data1(i,j,k) for i<Nx and 
data(i,j,k) = data2(i-Nx,j,k) for i>=Nx  

Is that right?

Thanks!
Alberto

Hello ?lvaro,

It works! 
Rendering multiple overlapping data volumes with the same grid is possible with vtkGPUVolumeRayCastMapper.
Using numpy arrays was easy to gather the different 3-dimensional data arrays together by adding a 4th index to the combined array. 
The volume properties can be set independently for each one of the components.
Thanks for the help!

Best regards,
Alberto

Thanks for clarifying Alvaro, that's reassuring. I did make a quick test
with two volumes before I left work today and couldn't get the second one
to show up, but it's quite likely I made something wrong since I was in a
rush. I'll make a proper test when I'm back at work on Monday.

Thanks, I switched back to QVTKWidget and everything works as expected with your fix

it works ok after switching to qvtkwidget2, even the multisampling under linux, which wasn?t working with qvtkwidget

 

Ah, that's good to know. I believe when I was having the problem, I was working through Python, so was using QVTKRenderWindowInteractor (or maybe my own similar class), which is yet another thing (QVTKWidget / QVTKWidget2 are not wrapped).

Glad it worked out anyway. Nowadays I'm using C++ and QVTKWidget2 too.

 

I was actually wrong. I had a look at my code, and I'm using QVTKWidget (not QVTKWidget2), and what I did to get around problems with Z-ordering and also to get multisampling working reliably was this (from the constructor of my QVTKWidget subclass):

    QSurfaceFormat surfaceFormat = windowHandle()->format();
    surfaceFormat.setSamples(8);
    surfaceFormat.setStencilBufferSize(8);
    windowHandle()->setFormat(surfaceFormat);

Hope that helps someone else using QVTKWidget.

I don't remember exactly, but I think I had the same problem. Should be somewhere on this list I think.

I think it's possible to work around by manually setting the stencil buffer size on the QGLFormat used by the widget.

On the bus at the moment so have limited ability to search.

Subject: [vtkusers] scatterplot with different marker shapes,
	sizes and colors?
Message-ID: <aff439e7-6c74-55db-9142-adbdb92d2091@emmenlauer.de>


I've been using vtkPlot to get a simple and easy-to-use scatterplot,
and it works great! But ideally I'd like to also have different marker
sizes, i.e. to specify a marker size for each point. I could trace the
code into vtkOpenGLContextDevice2D::DrawPointSprites() where the marker
sprites are drawn. But a recommendation would help - is it even possible
and runtime-efficient to have variable sizes? Or would it come at a huge
performance penalty? How is the best way to achieve it, is it required
to patch vtk or are the other means?

All the best,

    Mario Emmenlauer

Hello,

I try to compile Activiz with VTK6.3, using the activizdotnet from zamirkhan in GIt, unfortunately I meet the error of error CS1577, attached please see the screenshot, unfortunately some Chinese character insided, but from where you still can see what the error is. actually I have already generate myself snk, and I check  the "Kitware.VTK.CscArgs.txt", where I am sure the snk file path is correct.
can anyone help me to figure it out what's the problem and how to solve it?

Thanks in advance.
James

Subject: [vtkusers] Problem rotating vtkImageSlice
Message-ID: <c561b9bb-7aa7-4c5c-8a35-0b30bd2b76f3@me.com>

Hi,



If I build the example



VTK/Examples/Cxx/Images/ImageSlice
and add



?imageSlice->RotateX(1);


Which should, I think, rotate the image actor about its X axis by 1 degree, I instead get





which seems incorrect.



I can rotate about Z.



Is there something I'm not doing correctly, or is this a bug?



I also tried RotateWXYZ(1,1,0,0) and get the same result.



This is VTK 7



Thanks



Rick

Hi Rick,

You're seeing this because you are doing an out-of-plane rotation on an
image that has only one slice.  The rotation is around the image origin,
which (in this case) is at the bottom-left corner of the image.

The vtkImageResliceMapper has a SetSlicePlane() method:
http://www.vtk.org/Wiki/VTK/Image_Rendering_Classes#vtkImageResliceMapper
You must rotate this SlicePlane when you rotate the vtkImageSlice.

 - David

You should also try vtkImageSliceMapper instead of vtkImageResliceMapper,
perhaps its behavior will better suit your requirements.

HI Matias,


will you please be kind to send to me the Activiz source code of ActiViz 6.3, I am trying to build it with VTK 6.3, but I am failed, I have meet the error as the attached 2 screenshots shows(sorry it's in Chinese, but from the error code and the functions/file name maybe you can see what's the error)

Thanks & Best Regards
James

Hi Matias,


Thank you for your response! Is there a way for you to share the CMake and additional Activiz source changes you used to get the build working? I have already built VTK for OpenGL2 (both x86 and x64 as I would like to have both).


Thanks,
Zamir

Hi all,

I've been able to successfully build Activiz 6.2 (both x86 and x64) thanks
to all of the knowledge in this thread and the files provided by Mark.

I'm wondering if anyone has been able to successfully build Activiz 6.2 (or
above) with the underlying VTK compiled for OpenGL2. I think I need to add
references to the vtK...OpenGL2 libraries in the Activiz CMake, but I have
yet to be able to do that successfully.

Thanks,
Zamir

However, from my painful experience, a right CMake version might be one of the important thing in building ActiViz.. You must choose an older version rather than the newest!  For example, CMake 2.8.8 works well for me.

If you compile ActiViz.Net with .NET 4.0, the patched ActiViz.net and mummy source by Mark DeArman is suggested. They can be downloaded from:

??? [vtkusers] Activiz with VTK6.3 compile error CS1577
Hello,

I try to compile Activiz with VTK6.3, using the activizdotnet from zamirkhan in GIt, unfortunately I meet the error of error CS1577, attached please see the screenshot, unfortunately some Chinese character insided, but from where you still can see what the error is. actually I have already generate myself snk, and I check  the "Kitware.VTK.CscArgs.txt", where I am sure the snk file path is correct.
can anyone help me to figure it out what's the problem and how to solve it?

Thanks in advance.
James

Hi Frank,

It looks like you are doing a data transformation when you should be doing
a view transformation.  Don't rotate the actor if your goal is to rotate
the view.  When you rotate the actor, you are changing the relationship
between data coordinates and world coordinates.

If you want a sagittal view, then you can rotate the view by moving the VTK
camera.  The mapper has a method SliceFacesCameraOn() that can be used to
make the mapper automatically extract a slice in the correct orientation.

Also, please limit the width of inlined images to around 1000 pixels or
less.  Large inlined images make your email hard to read on my system (I
wish that gmail would auto-shrink oversized inlined images, but
unfortunately it displays them full-size, even if they're several times the
size of the display).

Hi David,



Sorry about the attachment.



Well, I'm pretty far along with my work on this, so I'd like to try the vtkPlane orientation as a solution if possible.



using the example code,? If I create a vtkPlane, set its origin to 0,0,0 and set its normal to 1 0 0 (instead of 0,0,1) and call

?imageResliceMapper->SetSlicePlane(plane);


I see a thin line. Seems correct. If I change the interactor style to Trackball camera, and rotate the camera around it seems the image is only 1 unit wide however.



Is there something else I need to do to get the image to map to a plane with different orientation?


THanks

Hi David,



Thanks for the reply. I'm still a bit confused about what I've tried and why it doesn't work....



So, I have 3 slice views and in the screenshot the Axial View is lined up appropriately (image position patient is in the correct place, and each slice is in correct place etc) with the world coordinates by using the image reslice axis and camera etc to align the DICOM coordinates and the VTK World coordinates.



I now want to orient the sagittal slice so that it aligns with the world coordinates.



(see screen shots)





I believe I need to rotate the slice (if I could rotate the actor) about Z 90 CCW and then about its new X 0- degrees and then move the camera about world Y 90 and the roll the camera 90 to get the sagittal voxels DICOM aligned with the World Coordinates.



I tried various parameters for the resliceMapper->SetSlicePlane() but the slice just dissapears off screen somewhere so I must be getting sometime wrong.



How would I use the SetSlicePlane to achieve this?


Thanks

The vtkImageResliceMapper has a SetSlicePlane() method:
http://www.vtk.org/Wiki/VTK/Image_Rendering_Classes#vtkImageResliceMapper

You must rotate this SlicePlane when you rotate the vtkImageSlice.

Check the extent of the input image to make sure all of the slices were
loaded.

Hi

I'm using the VTK example which creates an in memory single cyan slice.....

Thanks

If you only had one input slice, then why would you be surprised that
reslicing at 90 degrees gives an output that is only one pixel wide?

Okay, let me try to understand this.  Please let me know if I'm wrong on
any of the following points.

1) You have a CT scan, consisting of several slices (I assume around 100
slices) with uniform spacing.

2) You have a single XA image.  An XA is a projection image, in contrast to
CT which is a tomographic image.

3) You need to find the direction-of-projection through the CT volume such
that it matches the XA.

This is generally done by creating a DRR a MIP of the CT.  I'm not sure how
you plan to achieve this by rotating a slice.

I meant DRR "or" MIP (Digitally Reconstructed Radiograph, Maximum Intensity
Projection).

Hi David

I have a preop CT typically 600 - 900 slices.  The intra-op ct ( DICOM says modality is XA , essentially a lower res non - HU calibrated spin volume) is from a c-arm right before surgical procedure. I need to align the intra op with the preop. This is manual registration by moving 3 orthogonal slice pairs to create a 6 DOF registration matrix. My initial implementation of the slices ( Axial, sagittal, etc) has them all "facing" the user. Rolling the scroll wheel moves through the slices.

This is all parallel projection.

We have a dual volume renderer written in OpenCL that shows the alignment in 3D of the two ( fixed, moving ) volumes.

Now I would like to, for simplicity, align the 
slices so the world coordinates line up with my ijkLPS transform.
In the case of direction cosines == identity, HFS position, my sagittal slice can be aligned with world coordinates by turning it so the patient is head pointing out of screen (+Z Inferior - Superior), face down ( + Y Anterior to Posterior) ( +X Left to Right). 

The I would move the slice to proper location in space based on image position patient. ( one coordinate is always 0 ) And then move the camera so the slice normal is aligned with the camera view vector.

This is all working correctly with our 3D views and associated surgical equipment. I thought I would be able to manipulate the slices in space as any other actor ( rotate, translate, etc) but perhaps that's not possible? When I try to rotate the image slice ( which is a Prop3D) the image seems to be resliced  as you say, instead of the prop being rotated.

Thanks 

Rick Frank

Rotating the vtkImageSlice (i.e. the actor) rotates the data with respect
to world coords.  Rotating the SlicePlane of the vtkImageResliceMapper
rotates the cut plane wrt world coords.  So between these, you have full
control over both the data-to-world transformation, and over the cut plane
that you want to use to extract an oblique slice from the rotated data.  So
what you are trying to do is definitely possible.

Here is the code that I use to display images for registration:

So between these, you have full control over both the data-to-world transformation, and over the cut plane that you want to use to extract an oblique slice from the rotated data.  So what you are trying to do is definitely possible.

Hi again Aashish, did you or Alvaro make any findings regarding this?

I have to ask: Since you called it an "issue", do you mean that it should
be possible to render volumes larger than 2048 voxels in one dimension
(despite the graphics card texture size limit)?

Because at the moment I'm working under the assumption that it should not
be possible, and I'm trying to work around it in our application by trying
to work with multiple smaller volumes instead. But if it turns out it's a
bug/unintended limitation in VTK, I might not have to do that (if it's
fixed/can be worked around).

Thanks in advance,
Elvis

Still didn't find a way to extract an area with the highest point density.
The closest solution so far was to extract the regions with size greater than a given threshold by applying two connectivity filters:
? // Get all regions? vtkSmartPointer<vtkPolyDataConnectivityFilter> connectivityFilter = vtkSmartPointer<vtkPolyDataConnectivityFilter>::New();? connectivityFilter->SetInputConnection(cleanFilter->GetOutputPort());? connectivityFilter->SetExtractionModeToAllRegions();? connectivityFilter->Update();??? // Get region sizes? vtkSmartPointer<vtkIdTypeArray> regionSizes = connectivityFilter->GetRegionSizes();??? vtkIdType sizeThresh = 10;??? // Select only regions with size > sizeThresh? ?vtkSmartPointer<vtkPolyDataConnectivityFilter> newConnectivityFilter = vtkSmartPointer<vtkPolyDataConnectivityFilter>::New();? newConnectivityFilter->SetInputConnection(connectivityFilter->GetOutputPort());? newConnectivityFilter->SetExtractionModeToSpecifiedRegions();??? for (vtkIdType regionIndex = 0; regionIndex < connectivityFilter->GetNumberOfExtractedRegions(); ++regionIndex)? {? ? if (regionSizes->GetValue(regionIndex) > regThresh)? ? {? ? ? newConnectivityFilter->AddSpecifiedRegion(regionIndex);? ? }? }??? newConnectivityFilter->Update();????? Now I need to find a way to select the bigger area that contains the most number of such regions...

Hi, ?Given a poly data that represents a 3D model and a radius, isthere any way to retrieve a region (sphere?) where the point density is thehighest (i.e. the sphere with the given radius that contains the highest numberof points within itself)? ?Thank you,Ioana?

To give more details: In this example, it's two vtkVolumes, each have their
own vtkGPUVolumeRayCastMapper and vtkVolumeProperty, but they're added to
the same vtkRenderer. I've also tried having them share the same mapper and
property, but the result is the same.

Must I do something with layers on the vtkRenderer? Or is there some
setting to activate alpha channel on the volumes?

It seems I just had to set the sorting order of the frustum culler to
back-to-front with:

        auto frustumCoverageCuller =
vtkFrustumCoverageCuller::SafeDownCast(renderer()->GetCullers()->GetLastItem());
        frustumCoverageCuller->SetSortingStyleToBackToFront();

With that, it works (see attached screencast).

Does that make sense? I found that tip at

Subject: [vtkusers] vtkParametricFunction sub-classes in Python
Message-ID: <1472479387979-5740029.post@n5.nabble.com>

All,

I've been playing around with some parametric geometry in Python and I
wanted to use VTK to visualize the surfaces that I'm creating.  It seems
that extending the vtkParametricFunction class and using it with the
vtkParametricFunctionSource should work great.  However I can't seem to get
this to work from Python. 

Per Andrew Maclean's instructions in the "Parametric Equations for Surfaces"
pdf, I've created my geometry class by inheriting from vtkParametricFunction
and implemented the Evaluate, EvaluateScalar and GetDimension methods.  The
problem comes when I try to instantiate my new vtkParametricFunction object,
I get the following error:

    TypeError: this is an abstract class and cannot be instantiated.

I though maybe it was because I had not explicitly implemented the other
virtual methods in the vtkParametricFunction interface. So I implemented all
of those as well and I still get the same error. Then I tried to inherit
from one of the C++ sub-classes of vtkParametricFunction and simply override
the Evaluate, EvaluateSCalar and GetDimension methods.  This works from an
instantiation stand point but my overrides of Evaluate and the like are not
being recognized.

Am I missing something?  Is it not possible to define vtkParametricFunction
sub-classes in Python for use with a vtkParametricFunctionSource object?  

FYI, I'm using Python3.5 and the VTK 7.0 package from conda-forge.


Thank you in advance,

jack

Hi Jack,

Virtual method hooks aren't implemented in the VTK python wrappers,
so a Python subclass of an abstract VTK class is still abstract.  It's one
of the many improvements I'd add to the Python wrappers if I had the
time (my current wrapper improvement project is to update the VTK
wrapper hint system).

David,

Thank you for getting back to me so quickly.

So I'm assuming that the lack of virtual method hooks in the wrappers is
also why I was not able to get my sub-classing hack of vtkParametricBour to
work.  I was hoping that by reimplementing Evaluate, EvaluateScalar and
GetDimension on a Python-based sub-class of vtkParametricBour I could get
it all to work.  Unfortunately it seems the vtkParametricBour.Evaluate() is
being used rather than my Python version.  Is this your understanding as
well?

In the meantime, I guess I'll what I'll try to do is to make a Cython
interface to vtkParametricFunction and create a Cython-based sub-class to
consume my parametric surfaces.  I'm pretty sure this will work although it
has been a little while since I used Cython for interfacing.  If you or
anyone else has any better suggestions, please pass them along.

Thank you again,

jack

My code base is getting pretty outdated.  I know Matias worked up a new building FAQ and etc which would be better to follow.
 My plan right now is to start a new build the first part of next year.
 I'll use github this time instead of our internal VS Team Foundation.
 Also I'll get all the latest glue code to support WPF ripped out of our application.
  
 The last time I worked on the 6.2 code, I was struggling to get mummy to generate the enums correctly.  Has anyone else ran into this issue?  Was it fixed in 6.3?

 James,
 I don't know the reason of your errors since it's incomplete. 
 However, from my painful experience, a right CMake version might be one of the important thing in building ActiViz.. You must choose an older version rather than the newest!  For example, CMake 2.8.8 works well for me.
  
 If you compile ActiViz.Net with .NET 4.0, the patched ActiViz.net and mummy source by Mark DeArman is suggested. They can be downloaded from:

    Hello,

I try to compile Activiz with VTK6.3, using the activizdotnet from zamirkhan in GIt, unfortunately I meet the error of error CS1577, attached please see the screenshot, unfortunately some Chinese character insided, but from where you still can see what the error is. actually I have already generate myself snk, and I check  the "Kitware.VTK.CscArgs.txt", where I am sure the snk file path is correct.
can anyone help me to figure it out what's the problem and how to solve it?

Thanks in advance.

I can also confirm that on an older system (SandyBridge, HD 3000 graphics),
I hit the limit at 1024, I guess because of the older graphics chip.

So my question is really: Should VTK be able to render volumes that are
larger (in some dimension) than the maximum texture size of the GPU? Or do
I have to split/juggle multiple volumes to work around this myself?

Subject: [vtkusers] Setting vtkCamera to custom modelview & volume

Sorry to bump my own thread but I still can't get this to work. For 2 
identical cameras in terms of position and projection transform, after 
adjusting the lights (or not) I get 2 different renderings.

The only difference is I apply worldToCamera transform by setting 
camera1->SetModelTransformMatrix(worldToCamera); whereas for camera2 I 
transform the vtkVolume.  In my understanding these should be identical 
in terms of positioning something in camera coordinate system.  But the 
rendering is different (sample attached as volume_vtk_7.0.0.jpg).

Weirdly enough if I render a cube instead of the volume, it works with 
VTK 7.0.0 (attached actor_vtk_7.0.0.jpg).  Same transform, both cameras 
work.  However, then same code rendering the cube doesn't work with 
6.3.0 (attached actor_vtk_6.3.0.jpg).  Not that I need to use 6.3.0.  
But I'm just at my wits end on what to try.

Can someone please have a look at my code and tell me how to get camera1 
to render properly?  Thank you

It will definitely depend on the GPU's limit.  A single dimension of 2048
would only work for graphics cards supporting  GL_MAX_TEXTURE_SIZE >= 2048.

That said, the mapper will soon support bricking (streaming the volume
texture in blocks, and rendering those blocks in separate passes), which
might be useful in this case.  There is an initial implementation available
in this branch:

Ah thanks, that's good news and exactly the info I was looking (and hoping)
for. As I have to use VTK 7.0 currently, I'll have to work around it in my
own code, and make sure volumes are of a manageable size, but it's very
good to see that bricking in VTK is on the horizon.

Do you know if that feature could possible make it into 7.1? Or is it too
recent?

Subject: [vtkusers] [vtk-user] - stop movement object 3D,
	indepedent of position camera
Message-ID: <1472497661505-5740042.post@n5.nabble.com>

Hello guys,

Is there any way to make a 3D object ignores the positioning of the camera?
Or apply it to the inverse movement rotation  of the camera.

I'm using vtkResliceImageViewer2 to display the three DICOM viewers  (Axial,
Sagittal and Coronal). In the axial, I mark one sequence of points
(vtkSplineWidget), which are used to create a panoramic view.

The problem is that the vtkResliceImageViewer2 object handles the camera in
order to create cutting the image. And my vtkSplineWidget object  is moving
along together with vtkResliceImageViewer2.

How do I stop the  vtkSplineWidget movement independent the camera position.

Hi Jose,

Use two superimposed renderers.  This provides two independent cameras.

// Main renderer (i.e. the one you already have)
window->AddRender(renderer);

// "Overlay" renderer (with its own camera and actors)
overlayRenderer->SetViewPort(renderer->GetViewPort()); // same viewport
overlayRenderer->EraseOff(); // do not erase before renderering
window->AddRenderer(overlayRenderer); // add on top of other renderer

The two renderers will share the depth buffer and color buffer, but each
will have its own camera, lights, and actors.

You can even make the "overlay" renderer so that its viewport only covers
part of other renderer.  After all, a renderer is just a class that renders
into a viewport within the window, you can choose the viewports however you
like.

Tranks David.
This form, I will be able to click the vtkResliceImageViewer 2 to start the
marking of points in vtkSplineWidget ?

Hi Bud,

There was a bug that was fixed recently. Can you try the latest master and
see if it is fixed? If it is, you can always cherry-pick that commit to 6.3
branch.

I honestly don't know how the VTK viewer and widgets react to mouse clicks
when two renderers are superimposed.

Hi Miaogui,

thank you very much for your reply. using the link from your mail, I try to compile the mummy,
but I meet the error as:

3>error CS1577: ??????? -- ?????????????????Kitware.mummy.Runtime.Unmanaged.dll?


I think it's the problem of "strong name signed" .NET Framework binaries, but I cannot figure how to handle it.

I have generated my own SNK and name it the same as the default one "Kitware.mummy.Runtime.pub.snk", and replace the default oone under the folder "mummy\Runtime", then I use cmake to generate the mummy solution, and compile it, then I got the error above.

I spent quite a lot of time searching online but cannot figure it out, will you please be kind helping me how to handle this problem?

Thanks
James

However, from my painful experience, a right CMake version might be one of the important thing in building ActiViz.. You must choose an older version rather than the newest!  For example, CMake 2.8.8 works well for me.


If you compile ActiViz.Net with .NET 4.0, the patched ActiViz.net and mummy source by Mark DeArman is suggested. They can be downloaded from:

Sorry to bump my own thread, but I'm still searching for a solution here. I
find it incredible that this wouldn't be possible. Anyone know how I can be
notified once editing of a transfer function stops when using these editor
widgets?

Hi James,
Here was my main build process, for your reference.

Object: ActiViz.NET 6.3 for .net 4.0.

1. A new installed Win7 32-bit professional system in a vmware virtural machine. The building process was done in the virtual machine.

2.  Install vs2008 trial,  and vs2010 trial for .net framework 4.0 (maybe vs2010 is unnecessary if .net frame 4.0 runtime is available).

3. Install cmake-2.8.8-win32-x86.exe

4. Download CVS from http://ftp.gnu.org/non-gnu/cvs/binary/stable/x86-woe/cvs-1-11-22.zip, unzipped and copy cvs.exe to C:\Windows\System32. Make sure the virtual machine can connet the network because it will download mummyExternalSourceTrees later.

5. Download the patched activiz.net and mummy source (thanks to Mark DeArman)
https://onedrive.live.com/redir?resid=C21891647818579A!108957&authkey=!ADS9VLyqTef24FY&ithint=folder%2c 
Unzip the Kitware_Source.7z, you'll get activizdotnet, gccxml, mummy, and VTK-6.2.0 folders. Replace the VTK-6.2.0 with VTK-6.3 from http://www.vtk.org/download/.
Folder tree, for example,
    C:\VTK\activizdotnet
    C:\VTK\gccxml
    C:\VTK\mummy
    C:\VTK\VTK-6.3.0

The following configure and build process can be found from  http://www.vtk.org/Wiki/VTK/CSharp/ActiViz/Build#Visual_Studio_2005_or_2008_.28gccxml_does_not_yet_work_with_Visual_Studio_2010.29

6. Build gccxml
(1) Configure gccxml, select Visual Studio 9 2008 compiler;
(2) Build the generated gccxml.sln with VS 2008 (release ) and INSTALL it.
(3) Run the gccxml_vcconfig.bat (can be found in the gccxml installation directory 'C:/Program Files/gccxml') in Visual Studio 2008 Command Prompt as adminstrator.

7. Build mummy
(1) in Visual Studio 2008 Command Prompt or Visual Studio Command Prompt (2010), run the command:
sn -k C:\VTK\mummy\Runtime\HUMG.mummy.Runtime.snk

(2) open C:\VTK\mummy\Runtime\CMakeLists.txt, search "IF(NOT Mummy_SNKEYFILE)", and insert the following sentence above it.
GET_FILENAME_COMPONENT(Mummy_SNKEYFILE "${CMAKE_CURRENT_SOURCE_DIR}/HUMG.mummy.Runtime.snk" ABSOLUTE)

(3) open C:\VTK\mummy\CMakeLists.txt, insert the following block below the first line "CMAKE_MINIMUM_REQUIRED(VERSION 2.8.3 FATAL_ERROR)":

SET(gccxml_compiler "${CMAKE_CXX_COMPILER}") 
IF(MSVC80) 
    SET(gccxml_compiler "msvc8") 
ENDIF(MSVC80) 
IF(MSVC90) 
    SET(gccxml_compiler "msvc9") 
ENDIF(MSVC90) 
SET (GCCXML_EXTRA_D_ARGS "_HAS_TR1=0")

(4) open C:\VTK\mummy\Examples\Vehicles\wrappers\csharpmummy\CMakeLists.txt, find the block (near line 82)
    ADD_CUSTOM_COMMAND( 
        OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}.xml 
        COMMAND ${gccxml_EXECUTABLE} 
        ARGS 
            -fxml=${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}.xml 
            -fxml-start=_cable_ 
            ${gccxml_include_args} -DCABLE_CONFIGURATION 
            --gccxml-compiler ${CMAKE_CXX_COMPILER} 
            ${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}_gccxml.cxx 
        DEPENDS 
            ${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}_gccxml.cxx 
            ${header_fullpath} 
            ${gccxml_EXECUTABLE}

replace it with the following block:
    ADD_CUSTOM_COMMAND( 
        OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}.xml 
        COMMAND ${gccxml_EXECUTABLE} 
        ARGS 
            -fxml=${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}.xml 
            -fxml-start=_cable_ 
            ${gccxml_include_args} -DCABLE_CONFIGURATION 
            --gccxml-compiler ${gccxml_compiler} 
            ${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}_gccxml.cxx 
            -D${GCCXML_EXTRA_D_ARGS} 
        DEPENDS 
            ${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}_gccxml.cxx 
            ${header_fullpath} 
            ${gccxml_EXECUTABLE} 
        )

(5) Configure the mummy in CMake with Visual Studio 9 2008
Change options:
    gccxml_EXECUTABLE='C:/Program Files/gccxml/bin/gccxml.exe'
    csc_EXECUTABLE='C:/Windows/Microsoft.NET/Framework/v4.0.30319/csc.exe'

(6) Build the Mummy.sln and INSTALL it.
An error might occur when build the INSTALL project:
    1> file INSTALL cannot find "C:/VTK/mummy/build/bin/x64/Release/Kitware.mummy.Runtime.dll".
My solution is: copy all files from C:/VTK/mummy/build/bin/Release to C:/VTK/mummy/build/bin/x64/Release, and INSTALL again. Then delete the C:/VTK/mummy/build/bin/x64/Release.

8. Build VTK-6.3.0 with default.

9. Build activizdotnet
(1) in Visual Studio 2008 Command Prompt or Visual Studio Command Prompt (2010), run the command:
sn -k C:\VTK\activizdotnet\HUMG.VTK.snk

(2) open C:\VTK\activizdotnet\CMakeLists.txt, search "if(AVDN_SNKEYFILE STREQUAL "")", and insert the following sentence above it.
GET_FILENAME_COMPONENT(AVDN_SNKEYFILE "${CMAKE_CURRENT_SOURCE_DIR}/HUMG.VTK.snk" ABSOLUTE)

(3) search the block
set(gccxml_compiler "${CMAKE_CXX_COMPILER}") 
if(MSVC80) 
    set(gccxml_compiler "msvc8") 
endif() 
if(MSVC90) 
    set(gccxml_compiler "msvc9") 
endif()

Insert the line below the block:
SET (GCCXML_EXTRA_D_ARGS "_HAS_TR1=0")

(4) search the block :
      add_custom_command( 
        OUTPUT ${ActiVizDotNet_BINARY_DIR}/xml/${cxxclass}.xml 
        COMMAND ${gccxml_EXECUTABLE} 
            -fxml=${ActiVizDotNet_BINARY_DIR}/xml/${cxxclass}.xml 
            -fxml-start=_cable_ 
            ${gccxml_include_args} -DCABLE_CONFIGURATION 
            --gccxml-compiler ${gccxml_compiler} 
            ${ActiVizDotNet_BINARY_DIR}/xml/${cxxclass}_gccxml.cxx 
        DEPENDS 
            ${ActiVizDotNet_BINARY_DIR}/xml/${cxxclass}_gccxml.cxx 
            ${header} 
            ${gccxml_EXECUTABLE} 
        )

Replace it with:
        ADD_CUSTOM_COMMAND( 
            OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}.xml 
            COMMAND ${gccxml_EXECUTABLE} 
            ARGS 
                -fxml=${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}.xml 
                -fxml-start=_cable_ 
                ${gccxml_include_args} -DCABLE_CONFIGURATION 
                --gccxml-compiler ${gccxml_compiler} 
                ${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}_gccxml.cxx 
                -D${GCCXML_EXTRA_D_ARGS} 
            DEPENDS 
                ${CMAKE_CURRENT_BINARY_DIR}/xml/${cxxclass}_gccxml.cxx 
                ${header} 
                ${gccxml_EXECUTABLE} 
            )

(5) search "vtkRenderingFreeTypeOpenGL", delete it. (The library is removed from VTK 6.3)

(6) Configure the activizdotnet with CMake with Visual Studio 9 2008
Change options:
    gccxml_EXECUTABLE='C:/Program Files/gccxml/bin/gccxml.exe'
    csc_EXECUTABLE='C:/Windows/Microsoft.NET/Framework/v4.0.30319/csc.exe'
    AVDN_SNKEYFILE='C:/VTK/activizdotnet/HUMG.VTK.snk'
    AVDN_BUILD_CSHARP_DEBUG=OFF

(7) Open the generated ActiVizDotNet.sln in VS 2008, changed to release mode. ALL_BUILD, then INSTALL.
Some errors:
1) the following error occur for some projects:
    error LNK2019: unresolved external symbol "void __cdecl vtkRenderingContextOpenGL_AutoInit_Construct(void)
    SOLUTION:  add "C:\VTK\VTK-6.3.0\build\lib\Release\vtkRenderingContextOpenGL-6.3.lib" to the project's C++ link list

2) "vtkOpenGLFreeTypeTextMapper" not found, double click the error to found the error position, then just comment out the sentences:
      using (Kitware.VTK.vtkOpenGLFreeTypeTextMapper o = Kitware.VTK.vtkOpenGLFreeTypeTextMapper.New()) 
        { 
            s = o.ToString(); 
        }

3) vtkCommonEL_dll, vtkGraphicsEL_dll not found. Replace them with vtkCommonCoreEL_dll, vtkFiltersProgrammableEL_dll, respectively.


That's ALL. If you use the VTK-6.2.0 instead of VTK-6.3.0, there might be less build errors.

Good luck!

Does vtkDelaunay3D have a GPU implementation?

Also does VTK use the GPU for rendering.

I would like to use a scalar property to pilot the alpha channel of a lookup table.
The property must be different from the one that drives the color.

Suppose I have a data source (could be ImageData or StructuredGrid)

-    Cell scalars "value" --> determine RGB values

-    Cell scalars "reliability" --> determine alpha values.

I don't want to do volume rendering, just to fade out some cells in a surface representation.

What approach would you suggest?

Thanks,
Federico

Subject: [vtkusers] Area delimited by two curves
Message-ID: <c68ba3ae-7313-18b0-3ab2-fcdc1079b46f@telefonica.net>

Hello,

I am trying to plot the area between two curves in vtkChartXY.

My environment is Python and VTK 6.2.

I have tried this:

area=chart.AddPlot(3)
area.SetInputData(table)
area.SetInputArray(0, "arrayX")
area.SetInputArray(1, "arrayY1")
area.SetInputArray(2, "arrayY2")

But the output is the colored area between arrayY1 and the x-axis.

Changing the argument of AddPlot to 6, throws an error:

     area.SetInputData(table1)
AttributeError: 'NoneType' object has no attribute 'SetInputData'

Could someone direct me in the right direction?

Thanks

Hi Sunil,

Concerning the vtkDelaunay3D algorithm, it is not implemented on GPUs 
and I don't believe there is currently an option for that (in VTK and 
generally in the public domain).

While the vtkDelaunay3D is convenient as directly available in VTK and 
with VTK licensing terms, I have experienced significant speed gains 
using TetGen (http://wias-berlin.de/software/tetgen/) - this on meshes 
with 0.5 to 2 million tetrahedral elements. The only drawback is that 
one has to develop his/her own methods calling TetGen from VTK, and 
abide to the specific licensing conditions.

Please note also that a number of alternatives exist:

Best Regards,

Andrea

In response to Sunil's second question - does VTK use the GPU for
rendering?. Yes. More precisely VTK uses OpenGL, which more often than not,
uses the GPU.

Subject: [vtkusers] vtkRenderer->UseShadowOn() & QVTKWidget
Message-ID: <CAJ=jcXvqBOFH6KVTiFA2JZZMg8VABdW-XFZ-bndAXFXFuZSmug@mail.gmail.com>

Dear all,

I am trying for quiet a long time to make the projected shadows visible in
a vtkRenderWindow.
I am working with vtk7.0 and OpenGL2 Backend.
I am using scene lights and the function useShadowOn() (much more practical
than the available examples: TestShadowMapPass.cxx ;) ).

This works well and creates the shadows as I expected them.

However, I am trying to integrate this in a QVTKWidget and problem start
there.
As soon as I combine shadows and QVTKWidget it crashes without any message.
I am using Qt-5.7

I didn't find any relevant information helping me to understand this
problem and how to solve it. Does anyone as any idea about what could be
wrong in my code or in the elements I am using?

Please find my code below:

Hello vtkusers,



There are ways to apply  two different vtkInteractorStyle against same
actor? I have an actor that I used vtkInteractorStyleTrackballCamera to
pick some points by mouse leftclick (OnLeftButtonDown()) that works
smoothly , then I have two actors with same
vtkInteractorStyleTrackballCamera and I need pick/select distinctly one
between these to start some process independently with
vtkInteractorStyleTrackballActor. However, once applied TrackballCamera
style and I am applying TrackballActor to same actors one of the actors
that is using LeftButton event from TrackballCamera doesn?t respond the new
style.



My actors (two independent cylinders source)



I am following this example to TrackballActor:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/SelectAnActor

I am following this example to TrackballCamera:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/DoubleClick



Thank you very much for any help,

Hi Aashish,

I compiled VTK revision dbae27c5ee61cb7507d893001ae8d93a580f9e72 of the 
master branch and still the same problem with volume rendering. 
Rectangles render fine.

The worldToCamera transform applied through SetModelTransformMatrix() 
seems to deform the volume for volume rendering - yet it does not deform 
the rectangle geometry.  Does this behavior seem right or should I file 
a bug report? I'm a new user so it's entirely possible this is intended 
behavior, but to me at a glance and reading API documentaiton it doesn't 
seem right. Yet another screenshot attached.

Thanks.

Subject: [vtkusers] vtkRenderWindow - size change in off screen rendering
Message-ID: <1472583079476-5740068.post@n5.nabble.com>

Hello,

I am trying to create an off-screen renderer with a specific size to
transmit to an external monitor. I have code working in VTK 6.3, but am
having trouble on VTK 7.0 (Windows 10, 64-bit). I tracked down the problem,
but do not know how to avoid this issue and maintain a constant size for an
offscreen render window. During the first call to Render(), the function
vtkWin32OpenGLRenderWindow::GetSize() forcibly sets the size to "the current
window size" rather than using the values previously assigned to force.
Immediately upon entering the function, the "Size" variable correctly
identifies the window size; however, since the "Mapped" variable is turned
on by the call to OffScreenRenderingOn(), it forces the size to that
identified by GetClientRect() --> why is this the case for an offscreen
renderer?

Thanks in advance,
Ryan

  renderWindow->SetSize(width, height);
  renderWindow->StereoCapableWindowOn();
  renderWindow->StereoRenderOn();
  renderWindow->SetStereoTypeToSplitViewportHorizontal();
  renderWindow->OffScreenRenderingOn();
  renderWindow->AddRenderer(renderer.GetPointer());
  renderWindow->Start();

  // add actors

  renderWindow->Render();

Message-ID: <CANSF80UJPNB4eS-1fiX0hVfD+-OesjpygW5P-bQ2XBYOVNcL3w@mail.gmail.com>

Hi,

I'm clicking on the playback buttons but they do not trigger the overridden
method. I tried making the call explicitly and it does work. I also tried
some enable flags, but did not seem to work. Any help is appreciated. I got
here by trying out an example->
https://itk.org/Wiki/VTK/Examples/Cxx/Broken/Widgets/PlaybackWidget

public class PlaybackRepresentation: vtkPlaybackRepresentation{
    public new static PlaybackRepresentation New()
    {
        return new PlaybackRepresentation();
    }

    public PlaybackRepresentation()
    {
    }

    public override void Play()
    {
        Log("Play pressed.");
    }}
PlaybackRepresentation   pbRep    = PlaybackRepresentation.New();
vtkPlaybackWidget        pbWidget = vtkPlaybackWidget.New();
public void AddPlaybackWidget(){
    pbRep.SetShowBorderToOff();
    pbRep.SetPosition( 0.43, 0.05);
    pbRep.SetPosition2(0.14, 0.07);

    pbWidget.SetInteractor(_style.GetInteractor());
    pbWidget.SetRepresentation(pbRep);
    pbWidget.On();

    pbRep.Play(); // This does work, but clicking
                  // on the button does not trigger the method call }

Subject: [vtkusers] How to use vtkExtractSelection on points
Message-ID: <1472634860121-5740070.post@n5.nabble.com>

Hi all,

I am confused about how to use a vtkSelectionNode combined with
vtkExtractSelection. I basically want to extract all points from a
vtkPolyData which have their Z coordinates in a certain range e.g. -5.0 < Z
< +5.0.
Could anyone help with this?

Kind regards,

Dave

Hi Dave,

Use this example as your reference:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/ExtractCellsUsingPoints

The condition for adding a point ID to the vtkgidtypearray (while iterating
over all points in the polydata), in your case would be
      -5.0 < polydata->GetPoint(i)[3] < 5.0

Beyond that change, the rest of the code would work as is.

?Hope that helps.?

Subject: [vtkusers] Memory not released when volumes are removed
Message-ID: <CAE-7VJn9dt-p_3Dwr0cfCSHHGXG0pZCvP-m0s-e77rzWyHsB8A@mail.gmail.com>

Hi all,

Before loading a new dataset into our app, I'd like to remove all existing
volumes from the renderer, which I believe should lead to them being
destroyed as well, since I have no other references to the volumes
(currently).

What I tried was

    // Remove all existing volumes
    auto volumes = renderer()->GetVolumes();
    volumes->InitTraversal();
    for (int i = 0; i < volumes->GetNumberOfItems(); ++i) {
        qDebug() << "removing volume";
        vtkSmartPointer<vtkVolume> volume = volumes->GetNextVolume();
        qDebug() << "before:" << volume->GetReferenceCount();
        renderer()->RemoveVolume(volume.GetPointer());
        qDebug() << "after:" << volume->GetReferenceCount();
    }

The output I get each time I load a new dataset (actually the same, but
doing it repeatedly) and execution passes by this cleanup code is:

removing volume
before: 3
after: 1
removing volume
before: 3
after: 1
removing volume
before: 3
after: 1

Which sort of makes sense to me: Apparently the renderer holds two
references to the volume, since the refcount goes down by 2 when I remove
the volume from the renderer. The remaining reference is held by the
vtkSmartPointer I created inside the loop.

But, what surprises me is that memory usage does not seem to go down when
this code is executed. I would expect that when the scope of the for loop
body is exited, the refcount will drop to zero, so the volume should be
deleted. And I guess it probably is.

But looking at the memory usage when repeatedly loading datasets (and thus
clearing the previous), the resident memory used by the app accumulates.

Must I somehow remove the mapper / underlying image data as well? I'm not
holding any references to these, so I would have expected them to die along
with the volume.

Helpful for any tips on why this cleanup is apparently not enough to avoid
memory accumulation.

Thanks,
Elvis

Hi Elvis,

I noticed the same behavior before ( here is the topic http://vtk.1045678.n5.nabble.com/memory-leak-in-vtkStructuredPoints-or-am-I-doing-something-wrong-tt5738805.html )

Looks like it is the standard behavior of Linux (although very weird), since this is not happening in Windows or OS X.

Best,

Robert

Subject: [vtkusers] Memory not released when volumes are removed

 

Hi all,

Before loading a new dataset into our app, I'd like to remove all existing volumes from the renderer, which I believe should lead to them being destroyed as well, since I have no other references to the volumes (currently).

What I tried was

    // Remove all existing volumes
    auto volumes = renderer()->GetVolumes();
    volumes->InitTraversal();
    for (int i = 0; i < volumes->GetNumberOfItems(); ++i) {
        qDebug() << "removing volume";
        vtkSmartPointer<vtkVolume> volume = volumes->GetNextVolume();
        qDebug() << "before:" << volume->GetReferenceCount();
        renderer()->RemoveVolume(volume.GetPointer());
        qDebug() << "after:" << volume->GetReferenceCount();
    }

The output I get each time I load a new dataset (actually the same, but doing it repeatedly) and execution passes by this cleanup code is:

removing volume
before: 3
after: 1
removing volume
before: 3
after: 1
removing volume
before: 3
after: 1

Which sort of makes sense to me: Apparently the renderer holds two references to the volume, since the refcount goes down by 2 when I remove the volume from the renderer. The remaining reference is held by the vtkSmartPointer I created inside the loop.

But, what surprises me is that memory usage does not seem to go down when this code is executed. I would expect that when the scope of the for loop body is exited, the refcount will drop to zero, so the volume should be deleted. And I guess it probably is.

But looking at the memory usage when repeatedly loading datasets (and thus clearing the previous), the resident memory used by the app accumulates.

Must I somehow remove the mapper / underlying image data as well? I'm not holding any references to these, so I would have expected them to die along with the volume.

Thanks,

Elvis

Ah right, now I remember your post. I'll do some more testing to verify
that this is actually what's happening in my case, but it likely is.

In ActiViz .NET, you cannot derive a new class from a VTK wrapper
class. You would have to write the class in C++ and then wrap it to
generate the class on the managed/.NET side.

You can intercept events fired from the VTK objects: there should be
decent examples of how to do that in ActiViz .NET, but no deriving
classes in the wrapper layer without having a corresponding class on
the unwrapped side.


Hope this helps,
David C.

Message-ID: <50b6ae1e-8a9e-4120-bcd7-47c1ca2786c4@me.com>




Hi,



If I modify the TrackballCamera.cxx example file as follows





?// Render an image (lights and cameras are created automatically)
? renderWindow->SetWindowName("Trackball Camera");
? renderWindow->Render();

?// vtkSmartPointer<vtkInteractorStyleTrackballCamera> style =
?? vtkSmartPointer<vtkInteractorStyleDrawPolygon> style =
?? ?? //?? ?? vtkSmartPointer<vtkInteractorStyleTrackballCamera>::New();
?? ? vtkSmartPointer<vtkInteractorStyleDrawPolygon>::New();



In VTK 6.3.x I get correct behavior ("lasso area is drawn")



Same code built with VTK 7 no drawing occurs, lasso area NOT drawn. Is this a known issue?



Thanks



Rick
