Subject: [vtkusers] Data type of vtkImageData
Message-ID: <CADiSopNpO0e333BqL+CfnMCoERHzjyqQPVDT4-Hy48JYKpqvvg@mail.gmail.com>

Hi,

I am wondering it there is a default data type for entries in a
vtkImageData?

Thanks.

Hi Chris,

I got carried away by new volume rendering code but now I am back to your
issue. I will report back.

thanks

Message-ID: <CA+cSwDQattdG1dUskWR3=F8Qz+M-L0CdgsuqW1bM45hXNdEUEg@mail.gmail.com>

Hi,

The VTK example data files v6.1.0 seem to be broken on
http://www.vtk.org/VTK/resources/software.html

The download links are:
http://www.vtk.org/files/release/6.1/VTKData-6.1.0.zip
http://www.vtk.org/files/release/6.1/VTKData-6.1.0.tar.gz

These archived files are 90MB, but when you decompress them you only
get an empty folder.  We have tried to decompress these files on Mac
and Linux.
We have seen this problem since this summer.  Maybe someone has
reported this problem but it is still not solved for us.

Thanks and regards,
Chun-Ming

Message-ID: <9A5A72BD-FF14-42CD-B1AB-B45F1ED349B4@gmail.com>

Hi all,

I?ve managed to build VTK v6.1.0 (release branch) against the Anaconda Python 2.7.8 under Windows 8.1 with Visual Studio 2012 without a hitch. However, as I can see from the changelog VTK no longer ships with a ?setup.py? to allow for the installation and packaging of the build. So:

1) How do you go about packaging to an .egg now for distribution?
2) How do you install it to a given ?site-packages? directory? As far as I could tell I just needed to build the ?INSTALL? upon setting the ?VTK_INSTALL_PYTHON_MODULE_DIR? variable under CMake to the ?lib\site-packages? directory of my Python installation. I should mention that during  ?Install? all the ?bin?, ?include?, etc directories end up under ?Program Files?. However, when trying to import VTK through python under the Python installation I just installed it in, the import fails with a:

```
from vtkCommonCorePython import *
Import Error: DLL load failed: The specified module could not be found
```

even though the vtkCommonCorePython.pyd file in under the same directory as all the others.

Any ideas?

Thanks a lot!
Adam

Hi Adamos,

In order to use the modules, all of the VTK DLLs must be in the PATH
(or you can copy them into the same directory as the .pyd files).

Subject: [vtkusers] How does one remove keypress events?
Message-ID: <CAFuxWZUAmZ3JqQkEHaUremE=BAr5mB6qJmVDJBAow_SsmZsPJg@mail.gmail.com>

Hi.

I'm having trouble getting rid of default keypress behavior.  I've had
considerably less luck with the documentation/examples and with google than
usual.

I'm using python 2.6.8 and vtk-5.10.1.  I've been working from the example
here:

http://www.vtk.org/Wiki/index.php?title=VTK/Examples/Python/Interaction/MouseEventsObserver

If I run that directly, it works, and hit 'w, it switches to wireframe.  I
want to disconnect any default key handling so that eventually I can
substitute my own.  That is, eventually, I want to make 'w' do something
completely different.

If I edit the end of that example to look like this:

interactor.RemoveObservers('KeyPressEvent')  #  <-- I ADDED THIS
interactor.RemoveObservers('LeftButtonPressEvent')
interactor.AddObserver('LeftButtonPressEvent', DummyFunc1, 1.0)
interactor.AddObserver('LeftButtonPressEvent', DummyFunc2, -1.0)
interactor.Initialize()
interactor.Start()

and run again, pressing 'w' still switches to wireframe.   I was hoping
that by removing all KeyPressEvent observers, the program would no longer
respond to keypresses.  Why does 'w' still produce a wireframe image, and
how do I disable 'w' (so I can override it with my own action)?

In trying to debug this, I figured I'd check whether 'KeyPressEvent' really
is the correct name.  If I go back to the original example code, and change
the end to look like this:

def keypress(obj, ev):  # <-- I ADDED THIS
    print "keypress!"      # < -- I ADDED THIS

interactor.AddObserver('KeyPressEvent', keypress)  # <-- I ADDED THIS
interactor.RemoveObservers('LeftButtonPressEvent')
interactor.AddObserver('LeftButtonPressEvent', DummyFunc1, 1.0)
interactor.AddObserver('LeftButtonPressEvent', DummyFunc2, -1.0)
interactor.Initialize()
interactor.Start()

then I see "keypress!" every time I press a key.  This tells me that
'KeyPressEvent' is the correct name. So I'm baffled.  I think I'm removing
all 'KeyPressEvent' observers, yet 'w' still switches to wireframe.   What
am I doing wrong?

Many thanks for any help.

Greg

The keypresses VTK handles by default are documented here:

    http://www.vtk.org/doc/release/5.10/html/classvtkInteractorStyle.html#details

(The 5.10 documentation, since that's the version you said you're using...)

The implementation for handling those keys is in the method
vtkInteractorStyle::OnChar, which is documented here:

    http://www.vtk.org/doc/release/5.10/html/classvtkInteractorStyle.html#a4357cd197cdf5c2d9ff8821cb4a50d82

The event triggering OnChar is the CharEvent, though, not the
KeyPressEvent. Try removing observers for CharEvent instead.


HTH,
David C.

Howdy,

The files are there, but they are hard to find and interpret. Look inside
the .ExternalData/MD5 directory and you will see lots of files named by
their checksum.

If you want human readable format: download the 6.0 data tarballs (there
are few data changes in-between releases), or download the data from our
cache at http://midas3.kitware.com/midas/community/27

Details:

In release 6.1 we moved to CMake's ExternalData facility to keep the
regression test data perfectly synchronized with the source code. To use
the tarballs, download and untar the source code then _optionally_ download
and untar the data into your source tree. This way you don't need network
access to compile VTK. If you skip the data (and of course leave
BUILD_TESTING on), cmake downloads each data file in turn at build time.

cheers





In 6.1 we moved to using CMake's ExternalData feature to keep our
regression test data synchronized with the source code.

Message-ID: <220BE31773B69D4C985CA5660D992DB16D5CA9B5@ex-mbx-pro-03>

Hello, 

Are there any examples available for generating particle pathlines in VTK? 

I have previously been working via the paraview interface (see example below) but would like to migrate to a pure VTK alternative and am having trouble understanding the process. 

Thanks for you help,
Fraser

    vol = pvs.PVDReader(FileName=pvdFile)
    source = pvs.XMLPolyDataReader(FileName=sourceVtpFile)
 
    pvs.SetActiveSource(vol)
    
    outputPaths = pvs.ParticlePath( SeedSource=source ) 
    outputPaths.SelectInputVectors = ['POINTS', 'Velocity']
    outputPaths.TerminationTime = terminationTime

    outputPaths.UpdatePipeline()

Message-ID: <B0FF49A9687290459C922D3D9578215A1EAD3205@TUT-EX02-PV.KSTG.corp>

Hello everyone
I am working on a project to visualize a tube structure. I have a working program for fixed points. Now I want to adapt the same for continuous application. My algorithm reads sensors and calculate 3D coordinates in C++. I want to feed this data to my visualization block in order to continuous visualization.
(I can visualize an actor continuously, where I could only change some properties of actor. e.g. SetPosition, Rotate, SetFontSize).  Please guide, how should I proceed to do so ? I tried updating vtkPoints and then interpolate these points and eventually tried rendering. Somehow my window shows nothing. once I saw a tube, which was showing some unrealistic shapes when I continued.
Any kind of guidance or help will be helpful.
Thank you in advance for your time taken.

(P.S. I am using TubesFromSplines from wiki as base to create visualization.)

With regards,
Mandar Mhatre

Hi David,

I just made a test using my data and your patch. It seems it is working
well, but I still don't get how the tolerance should be selected. I explain
myself with the following image and description: 
<http://vtk.1045678.n5.nabble.com/file/n5728996/PolyDataRasterization.jpeg>  

I'm using a very simple modified version of the VTK Cxx example,
PolyDataToImageData (code and data are here: http://git.io/s49TIA). I used
two polydata (the cells of both polydata are polylines, i.e. closed contours
along Z axis, that could be seen in the image in white), one reasonably
bigger than the other one (in the image you will see the body and a
structure inside), but keeping same properties. When using the Tolerance
(0.001) by default in the big polydata (the body), the 'raster' image is
generated correctly. When using the same code in the small structure, the
output image still has strange blank lines (left part of the image).
However, if I decrease considerably the Tolerance (0.00001), the result is
correct (right part of the image).

Does it makes sense to you? Is that normal?

Thanks!

Regards,

Ricardo

I suspect there are problems with the way that the tolerance is
applied during the rasterization part of the algorithm, and the larger
the tolerance, the more likely it is that problems will occur. For
best results you should use a tolerance of zero.

The patch is still sitting in the queue because I haven't had time to
test it properly.  If it is at all possible for you to provide data
sets or test code, that would be a big help.

 - David

Also, just in case you are using the patch that was attached to
the bug report, that patch is no longer up to date.  The most
recent code can always be found on the gerrit submission page:

Sorry about that. I accidentally sent before I could finish.

Hi,

I am trying to build VTK-5.10.1, but I keep getting an error.
My OS is 64 bit Ubuntu 14.04 running on Intel i7. I am trying to build
shared libs. When I build static libs, I don't encounter any problems.

During Cmake configuration, I am getting the following warnings (for both
static and shared):

The target name
"/home/trash001/Downloads/VTK5.10.1-build/Utilities/vtkhdf5/H5Edefin.h" is
unknown in this context.
This warning is for project developers. Use -Wno-dev to suppress it.

Hi Tanweer,

I suspect that you are missing some of the ubuntu dev packages.
For libGL.so, get libgl1-mesa-dev:

sudo apt-get install libgl1-mesa-dev

Hi all,

I encountered a problem in 3DSlicer with the auto calculation of window/level.  This may be a well-known issue.  For some big 3D tiffs, the algorithm gives bad w/l values, i.e. < 0.  I have tracked this to vtkImageAccumulate() in vtkImageAccumulate.cxx, where the histogram is computed.  The problem is that the voxel counts are stored in an int array (outPtr), and it's possible to have more than 2^31 voxels with the same value (e.g. 0).  I admit that these are unusual tiffs - they are binary and big - so it's a rather extreme case, but it seems that this is going to bite others as image sizes increase.

Cheers
Gib

Hi guys,

I'm working for a 3D Computer Vision Startup in Stockholm, Sweden.
We're working hard to develop cutting edge mass customization and 3D
reconstruction technology.

Recently we've been rated as one of the top Startups in Sweden. We
just received a several million funding and were on the stage with
Intel at IDF '14 in San Francisco. Together with them we presented our
newest innovation for mass customization using Intel's RealSense
technology (new generation depth camera).

At Volumental we're a young and dynamic team of more than 5 different
nationalities. Everybody counts, shapes and makes the company what it
is and it will become. I joined them a year ago and moved from Austria
to Sweden. During my time working here I often used VTK for various
purposes and I saw that the people on the VTK mailinglist were very
skilled and awesome. That is why I would love some of you to join us!
The company is currently looking for:

* Mobile Computer Vision Specialist
* Senior R&D Engineer
* Software Engineer
* Technical Team Lead

If you're amazing, committed and driven, but do not fit perfectly into
the roles above, just send us an application anyway and tell us why
you want to join us!

You find more information at https://www.volumental.com/jobs/

Best
Severin

Hi,

Yes, the tolerance 0 works with the data I have (the case on the github
project). However, I haven't had the time to check exactly the effect of
this parameter in the calculation (I imagine that lower tolerance implies
more time, specially in big meshes but not sure). Just to confirm, I'm using
the last version of the patch.

Good day

RaC

Hi Gib,

For VTK 5.10 and later, I added a new class called vtkImageHistogram
that uses vtkIdType for the histogram, and another class called
vtkImageHistogramStatistics that can automatically compute
window/level.  These new classes should work fine on large images.

Perhaps vtkImageAccumulate should also use vtkIdType (or should
have a selectable output type.)

Hi Ricardo,

The tolerance has no impact on speed.  The only things that effect the
speed are the complexity of the input and the resolution of the output.

Is it missing?  Is it a broken link?

And is it a broken link?  Does the file that it is pointing to exist?

So, this isn't specifically related to VTK anymore, but here are the
things that might be wrong with your system:

- you might be missing the libgl1-mesa-glx package, which
   provides /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1.2

- the links might have been broken during the installation of
   third-party OpenGL drivers (in which case you should
   hunt down all the broken links and fix them as best you can).

If you discover exactly what was wrong, please post your solution
on the list in case other linux users encounter similar problems.

 - David

Subject: [vtkusers] Compiling from source 6.0.0 but reproducible with 6.1.0
Message-ID: <CA+N8BFzE+RJwyD9mVKZ2=avTJRWOx-s+cEFdU2jOcQAz-7=Okg@mail.gmail.com>

Hi,

I've compiled various versions of VTK on various machines & compilers etc.

I'm trying a new compiler from Intel.

 CXXFLAGS=-openmp CFLAGS=-openmp CC=mpiicc CXX=mpiicpc LDFLAGS=-mt_mpi
cmake ../ -DBUILD_SHARED_LIBS=ON -DVTK_Group_MPI=ON
-DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX:PATH=/home/myhome/local
-DVTK_USE_SYSTEM_HDF5:BOOL=ON -DVTK_Group_Rendering:BOOL=ON

It always bombs at a xml2 lib :

[ 57%] make[2]: *** No rule to make target `lib/libvtklibxml2-6.0.so.1',
needed by `lib/libvtkIOInfovis-6.0.so.1'.  Stop.
make[1]: *** [IO/Infovis/CMakeFiles/vtkIOInfovis.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....

bash-3.2$ ls /usr/lib/libxml2.*
/usr/lib/libxml2.a   /usr/lib/libxml2.so.2
/usr/lib/libxml2.so  /usr/lib/libxml2.so.2.6.26

& obviously LD_LIBRARY_PATH is set correctly.

Guidelines on how to avoid this would be greatly appreciated.

VTK's by default tries to build a built-in version of libxml2 and
doesn't link to the system version. The question that needs solving is
why isn't vtk building vtklibxml2.

What is the state of VTK_USE_SYSTEM_LIBXML2 in your CMakeCache.txt?

Problem resolved.
Basically, the problem occurred because I used third party drivers (from
amd.com) to install my AMD graphics card. Most Ubuntu forums recommend that
you install repository drivers from the "Additional Drivers" tab/option in
Ubuntu Settings. Third party drivers apparently somehow
destroy/damage/corrupt the libGL.so link.

It is probably possible to somehow repair/reinstall libgl.so and other
relevant files, but in my case, I did a clean install of Ubuntu, and then
installed the drivers from "Additional Drivers". After that, VTK building
and installation gave me no problems.

Hi, I have read a *.stl to a vtkPolyData, and I checked it is Not Surface
Closed, is it possible to know a coordinate like (x:1.232323, y:2.232323, z:
3.1232323) is inside or outside this vtkPolyData?

Thankx!

Hmm first thing that comes to mind is using the vtkOBBTree, feed the polydata, use ?BuildLocator? and then use the 'InsideOrOutside? method.

Cheers,
Adam

thankx, I have tested vtkOBBTree and vtkSelectEnclosedPoints before, the
result are strange, because The data must be a closed surface, my data is
not a closed surface, so I can not use them.

Sorry wasn?t careful with your question, maybe someone else will have a decent idea. Not even sure what ?point inside polydata? would then mean to an open surface. I haven?t tried it but what about vtkCellLocator or vtkPointLocator?

Never mind.I have checked them before, they mainly find the closest point,
maybe it is not fit for my case.

Subject: [vtkusers] Extract block from Multi-block data by name?
Message-ID: <CAEhu9hAX3+xg76DVbUminouCrW6R=a7+TvejNn1G1v2ZEo_1Tg@mail.gmail.com>

Hello vtkusers,

I want to extract a block from a Multi-block dataset (read in using the
Ensight reader) using the block's name, but I had trouble finding such a
method in the documentation.  I found this thread
<http://public.kitware.com/pipermail/paraview/2011-March/020435.html> about
the same topic (but in Paraview), which suggested there was no method at
the time, but since it's from 3-4 years ago, I was wondering if something
in vtk had been written by now.

Thanks,
Evan Kao

Subject: [vtkusers] offscreen rendering on linux
Message-ID: <1412751071756-5729025.post@n5.nabble.com>

I have used the attached code to test offscreen rendering.I works well on
windows os,but on linux a blank window will always appear.I have searched
the relevant topics on the VTK forum,everyone  has different opinion,I have
tried some methods but it failed. Has someone used the VTK to develop
offscreen rendering and GPU accelerated rendering ? Can you give me some
suggestions?

Best wishes!

The following is the test code :

   vtkDICOMImageReader *dicomReader = vtkDICOMImageReader::New();
   dicomReader->SetDirectoryName("D:/image/SER25");
   dicomReader->Update();

  // Create the renderer, render window and interactor
  vtkRenderer *renderer = vtkRenderer::New();
  vtkRenderWindow *renWin = vtkRenderWindow::New();
  renWin->AddRenderer(renderer);

  // Connect it all. Note that funny arithematic on the 
  // SetDesiredUpdateRate - the vtkRenderWindow divides it
  // allocated time across all renderers, and the renderer
  // divides it time across all props. If clip is
  // true then there are two props
  vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
  iren->SetRenderWindow(renWin);

  
  // Create our volume and mapper
  vtkVolume *volume = vtkVolume::New();
  vtkSmartVolumeMapper *mapper = vtkSmartVolumeMapper::New();
  mapper->SetInputConnection( dicomReader->GetOutputPort() );

Subject: [vtkusers] How to know a coordinate inside or outside a
	vtkPolyData?

Hi,

You can do it using the vtkImplicitPolyDataDistance class (available
from VTK 6.1.0):

  implicit_function = vtk.vtkImplicitPolyDataDistance()
  implicit_function.SetInput(polydata)

  if implicit_function.FunctionValue([x,y,z]) <= 0:
   # inside
  else:
   # outside

There might be cases where it does not work, since in reality what it
does is calculate the distance to the closest point of the polydata
projected onto the surface normal at that point.

One case where I had problems was with two solids joined a one vertex,
leading to a normal vector at that point close to the null vector and
therefore incorrect inside/outside determinations.

But otherwise it tends to generally work, even with non-closed solids
like a simple plane, in which case it will consider one side of the
plane to be inside and the other outside.

I'm currently using it in a set of python scripts to create files in the
HDF5 format from geometries defined in .stl files for use with the MIT
MPB and MEEP simulation tools.

Another option, used in OpenEMS for instance, is to use the CGAL library
and count the number of intersections of a ray going from the point
towards the outside.
Code from 3D printing/slicing tools might also be worth looking into,
but I'm happy with my current vtkImplicitPolyDataDistance system.

There is still no specific method. You have to iterate over the blocks and
do a linear search.

I build VTK against Mesa with OSMesa every night for the dashboard.

Almost all tests pass for the offscreen builds and the DISPLAY
environment variable is not even set ( any attempt to open a window will
fail. )

I build my own Mesa with the update_mesa.sh script.

I build VTK with the CMake configuration in vtk_osmesa.cmake.

I don't see anything in your code that tries to enable offscreen
rendering. Can you add

renWin->OffScreenRenderingOn();

and give that a try?

Also, if you have built the VTK tests on linux, can you run

ctest -R vtkRenderingCoreCxx-TestOSConeCxx

That test does not show a window on my linux virtual machine that uses
Mesa for rendering. Let us know if that tests pops up a window for you
on linux with GPU-accelerated rendering.

Thanks,
Cory

Hi Cory,
I tried the vtkBooleanOperationPolyDataFilter on two closed surfaces which
are intersecting with each other.
I made sure that the normals of both the closed surfaces point outwards.
After i perform a union operation using the
vtkBooleanOperationPolyDataFilter, I get holes in the
final result. I am attaching the two individual STL files and the result of
the union operation. I am aslo attaching an image that shows the holes in
the resultant STL file. Is this expected behavior ? Can I do something to
get a surface without any holes?
input_1.stl <http://vtk.1045678.n5.nabble.com/file/n5729039/input_1.stl>  
input_2.stl <http://vtk.1045678.n5.nabble.com/file/n5729039/input_2.stl>

I have 25 assemblies with 3 parts (3 cylinders) each.. Rendering
performance degrades going from 1 to 25.

Is there a way to improve vtkAssembly rendering performance or should I be
using something like vtkPropAssembly instead?

thanks

Thanks for the feedback, Ryan.  What is your tolerance set to?  If it wasn't
set to zero, can you try it again with a tolerance of zero?

Also, a description of the data set (or even better, the data itself) would be
very useful.

David,
My tolerance was set to 0 in this example.

I?m attaching the data set that generated the image.  It was generated by using vtkCutter to slice a surface with a plane, followed by vtkStripper.  My volume spacing was set to 1.5 in all directions.

I assume)?  It wasn't clear to me in the documentation what method or

David,

I have noticed that if I run my data through vtkCleanPolyData with a tolerance of 1e-3, then this will removes the artifact.  I should also note that this artifact is also seemingly random throughout my dataset.

David,
My tolerance was set to 0 in this example.

I?m attaching the data set that generated the image.  It was generated by using vtkCutter to slice a surface with a plane, followed by vtkStripper.  My volume spacing was set to 1.5 in all directions.

Thanks for the feedback, Ryan.  What is your tolerance set to?  If it wasn't

Also, a description of the data set (or even better, the data itself) would be
very useful.

That's very useful info.  It suggests that my code isn't handling
degeneracies properly yet.

Are those type of polydata handled by the PolyDataToImageStencil as well,
i.e. a polydata having two polylines, one polyline inside the other one in
the same slice? (The image shows that the answer seems to be affirmative,
but I don't know if it is what the documentation of that class says). I have
always worked with closed contours or surfaces but not having some other
polydata/polylines inside.

Yes, vtkPolyDataToImageStencil works with nested contours.  This is
true both for polylines and surfaces.  Inner contours are treated as
holes (and contours inside those "hole" contours are filled, etc.).  I'll
update the documentation.

Formally, it is as if the interior of each contour is drawn with an XOR
operation.

Hi Santosh,

Your input geometries are fine. I, too, see missing polygons from the
output. This is definitely not expected. These missing triangles are
apparently being misclassified as to whether they belong to the union
or intersection surface.

I'll take a look to see if there is a quick fix for this.

That's good to know!

Just an additional info, I could reproduce @ryan45 error. In this data, this
problem happens with a relatively small spacing: around 2.5 (included) and
below; with higher values the result is correct. Polydata bounds> X:
2.32e+03 to 4.16e+03 (delta: 1.84e+03), Y: 2.47e+03 to 4.47e+03 (2e+03)

Hello everyone.
This is my first time with VTK and first time I am posting to this list. 
Does anyone have an idea why this code produces black image as a screenshot (attached). I installed vtk 6.1 on Ubuntu 14.04 (on virtual machine). This is just the example I found on http://www.cmake.org/Wiki/VTK/Examples/Cxx/Utilities/Screenshot for saving a screenshot of the render window. I looked around during 2 days but I haven't find a solution.
? 
Thanks a lot.

Subject: [vtkusers] Creating the dual of a graph - planar face traversal -
	vtkBoostGraphAdapter
Message-ID: <CAEQ0103UjvqR9nA1G3p83DikZGtOn7hYjJmwLH05OuPzh-sTSg@mail.gmail.com>

Hi All,

I'm trying to write an algorithm which creates the dual of a graph. To
check whether the graph is planar or not I use the *Boyer-Myrvold planarity
test* (Boost implementation) through the vtkBoostGraphAdapter. That works
fine (only on vtkUndirectedGraph-s but that's OK for now).
(http://www.boost.org/doc/libs/1_56_0/libs/graph/doc/boyer_myrvold.html)

To create the dual I need to traverse the faces of the planar graph for
which I also have a Boost tool called the planar_face_traversal_visitor.
(
http://www.boost.org/doc/libs/1_56_0/libs/graph/doc/planar_face_traversal.html
)
There's a guy, Aaron Windsor who implemented the appropriate visitor class
that is able to create the dual of a graph in Boost.
(https://github.com/aaw/boost_planar_graph_dual)
That also works fine using only Boost but I'd like to adapt this feature as
well using vtkBoostGraphAdapter.

Here's my code: http://pastebin.com/g0Mtw6Ph

These are my errors:

It seems I cannot provide an appropriate EdgeIndexMap parameter to the put
function in the 44th line. The vtkBoostGraphAdapter says that we can use
VTK arrays as property maps, I tried that one as well, with no success.
I've been dealing with this, reading the source code really deep and trying
a couple of things in the past few days but I can't really figure out what
the problem is. Is the vtkBoostGraphAdapter properly prepared for this kind
of usage?

Any kind of help appreciated!

Thanks in advance!

Subject: [vtkusers] Extract block from Multi-block data by name?

In Python, you can do this:

iter = mb.NewIterator()

while not iter.IsDoneWithTraversal():
    print iter.GetCurrentMetaData().Get(vtk.vtkCompositeDataSet.NAME())
    iter.GoToNextItem()


The C++ code is almost identical. The name is stored in the MetaData of
each block with the vtkCompositeDataSet::NAME() key.

Subject: [vtkusers] Creating the dual of a graph - planar face traversal
	- vtkBoostGraphAdapter
In-Reply-To: <CAEQ0103UjvqR9nA1G3p83DikZGtOn7hYjJmwLH05OuPzh-sTSg@mail.gmail.com>
References: <CAEQ0103UjvqR9nA1G3p83DikZGtOn7hYjJmwLH05OuPzh-sTSg@mail.gmail.com>
Message-ID: <CANuLzQFbX2EBryJjP=Gn7m2xz0ise4dY2so3eC6sDmZnpEzF=g@mail.gmail.com>

In your code, you are retrieving a vtkGraphIndexMap with:

property_map<vtkUndirectedGraph*, edge_index_t>::type e_index =
get(edge_index, in);

vtkGraphIndexMap is intended to be read-only and is already populated with
indices 0 through N-1, which are accessed with get(). It's actually an
identity map by index since indices are always in order, as you can see
here:

https://github.com/Kitware/VTK/blob/master/Infovis/BoostGraphAlgorithms/vtkBoostGraphAdapter.h#L1032-L1049

So I would suggest leaving out your initialization loop on lines 43-45.

Now, the remaining errors seem to require an operator[] on the
EdgeIndexMap, which is not currently implemented in vtkBoostGraphAdapter.h.
The needed code would be to replace the definition of vtkGraphPropertyMap
with something like this (not tested):

struct vtkGraphIndexMap; // forward declaration

template <>
struct property_traits<vtkGraphIndexMap>
{
  typedef vtkIdType value_type;
  typedef vtkIdType reference;
  typedef vtkIdType key_type;
  typedef readable_property_map_tag category;
};

struct vtkGraphIndexMap
{
  property_traits<vtkGraphIndexMap>::reference operator[](const
property_traits<vtkGraphIndexMap>::key_type& b)
    {
    return key;
    }
};

Try
  windowToImageFilter->ReadFrontBufferOff();

I need to look into why this is required...

Thank you for replying so fast!

I edited the vtkBoostGraphAdapter.h:

  struct vtkGraphIndexMap;


  template <>

  struct property_traits<vtkGraphIndexMap>

    {

    typedef vtkIdType value_type;

    typedef vtkIdType reference;

    typedef vtkIdType key_type;

    typedef readable_property_map_tag category;

    };



    struct vtkGraphIndexMap

    {

    property_traits<vtkGraphIndexMap>::reference operator[](const
property_traits<vtkGraphIndexMap>::key_type& key)

      {

        return key;

      }

    };


  inline property_traits<vtkGraphIndexMap>::reference

  get(

    vtkGraphIndexMap vtkNotUsed(arr),

    property_traits<vtkGraphIndexMap>::key_type key)

  {

    return key;

  }

I deleted the lines that fill the index map also. Unfortunately I still get
these errors:

   - /usr/local/boost_1_56_0/boost/property_map/*property_map.hpp*:302:19:

It seems to me that there's no operator[] for the iterator_property_map. Am
I missing something?

This particular problem looks like it stems from the distance
computation from one of the surfaces to another, which is computed in
vtkImplicitPolyData. It looks like the normal used in this calculation
is being flipped for the missing triangles. I'm tracking it down.

Best,
Cory

Sorry, I have made a mistake and uploaded the wrong code! Just like you said
the code should have the following line:

renWin->OffScreenRenderingOn(); 

A blank window still pops up. what I forgotten to say is I don't want to use

Thankx, very Helpful.

vtkImplicitFunction specifies an abstract interface for implicit functions.
Implicit functions are real valued functions defined in 3D space, w =
F(x,y,z). Two primitive operations are required: the ability to evaluate the
function, and the function gradient at a given point. The implicit function
divides space into three regions: on the surface (F(x,y,z)=w), outside of
the surface (F(x,y,z)>c), and inside the surface (F(x,y,z)<c). (When c is
zero, positive values are outside, negative values are inside, and zero is
on the surface. Note also that the function gradient points from inside to
outside.)

Implicit functions are very powerful. It is possible to represent almost any
type of geometry with the level sets w = const, especially if you use
boolean combinations of implicit functions (see vtkImplicitBoolean).

vtkImplicitFunction provides a mechanism to transform the implicit
function(s) via a vtkAbstractTransform. This capability can be used to
translate, orient, scale, or warp implicit functions. For example, a sphere
implicit function can be transformed into an oriented ellipse.

Subject: [vtkusers] What is the difference between ProjectionTransformMatrix
 of VTK and GL_PROJECTION of OpenGL?
Message-ID: <1412847249859-5729072.post@n5.nabble.com>

Hi,

I am having profound issues regarding understanding the transformations
involved in VTK. OpenGL has fairly good documentation and I was of the
impression that VTK is verym similar to OpenGL (it is, in many ways). But
when it comes to transformations, it seems to be an entirely different
story.

This is a good OpenGL documentation about transforms involved:
</a> <http://www.songho.ca/opengl/gl_transform.html> 

The perspective projection matrix in OpenGL is:

<http://vtk.1045678.n5.nabble.com/file/n5729072/OpenGLProjectionMatrix.jpg> 

I wanted to see if this formula applied in VTK will give me the projection
matrix of VTK (by cross-checking with VTK projection matrix).

*Relevant Camera and Renderer Parameters:*
camera->SetPosition(0,0,20);
camera->SetFocalPoint(0,0,0);
double crSet[2] = {10, 1000};
renderer->GetActiveCamera()->SetClippingRange(crSet);
double windowSize[2];
renderWindow->SetSize(1280,720);
renderWindowInteractor->GetSize(windowSize);
proj =
renderer->GetActiveCamera()->GetProjectionTransformMatrix(windowSize[0]/windowSize[1],
crSet[0], crSet[1]);


The projection transform matrix I got for this configuration is:

<http://vtk.1045678.n5.nabble.com/file/n5729072/VTKProjectionMatrix.jpg> 


The (3,3) and (3,4) values of the projection matrix (lets say it is indexed
1 to 4 for rows and columns) should be - (f+n)/(f-n) and -2*f*n/(f-n)
respectively. In my VTK camera settings, the nearz is 10 and farz is 1000
and hence I should get -1.020 and -20.20 respectively in the (3,3) and (3,4)
locations of the matrix. But it is -1010 and -10000. 

I have changed my clipping range values to see the changes and the (3,3)
position is always nearz+farz which makes no sense to me. Also, it would be
great if someone can explain why it is 3.7320 in the (1,1) and (2,2)
positions. And this value DOES NOT change when I change the window size of
the renderer window. Quite perplexing to me.

I see in VTKCamera class reference that GetProjectionTransformMatrix()
returns the transformation matrix that maps from camera coordinates to
viewport coordinates.
http://www.vtk.org/doc/nightly/html/classvtkCamera.html
<http://www.vtk.org/doc/nightly/html/classvtkCamera.html>  

OpenGL Projection Matrix is the matrix that maps from eye coordinates to
clip coordinates. It is beyond doubt that eye coordinates in OpenGL is the
same as camera coordinates in VTK. But is the clip coordinates in OpenGL
same as viewport coordinates of VTK?

Message-ID: <B0FF49A9687290459C922D3D9578215A1EAD3446@TUT-EX02-PV.KSTG.corp>

Hello Everyone,
I moved a step ahead of the problem I had asked before, I can update vtkPoints and can do the rendering using some features of vtkTimerCallback2 .
As I moved ahead, I am facing next hurdle. Though everything works fine, pipeline seems to be working correct, my render window stays inactive and doesn't update until I move mouse, to get continuous visualization of the moving sensors I had to keep the mouse moving over the render window (that's really stupid). Can anyone suggest what can be the possible problem ? and how to overcome this ?
One more info, as I run the project, command window pops out. I used it earlier to debug the code using cout function, but now everything is removed as I reach the final stage. Still command promt happens to stay there, totally blank . I dnt know if that's somehow related to my issue.
Looking forward for your experienced advices.
Thanks in Advance.

With regards,
Mandar Mhatre

Message-ID: <1412872106.35890.YahooMailNeo@web121306.mail.ne1.yahoo.com>

Hi all,

Is there a way to check whether a vtk pipeline has data to render? Many VTK algorithms display an error when they don't have input data. And these errors are harmless (don't crash the app), I would like to avoid them.

I currently am doing this as follows:

vtkMapper* mapper = actor->GetMapper();
if( 0 < mapper->GetTotalNumberOfInputConnections() &&
    0 < mapper->GetInputAlgortihm(0,0)->GetTotalNumberOfInputConnections() &&

    0 < mapper->GetInputAlgortihm(0,0)->GetInputAlgortihm(0,0)->GetTotalNumberOfInputConnections() &&
     .... )
{
    actor->VisibilityOn()

}
else
{
    actor->VisibilityOff();

}

One can easily imagine I would like to have a more convenient if statement, because currently I need to know exactly how long the pipeline is. 

For those interested:
This issue pops up, when when the rendering pipeline is created at the beginning a running the app, before the data is loaded Or when the data is unloaded in order to load new data.

Thank - Maarten

Santosh,

I looked at this problem in some depth today. The cylinder shape in
input_2.stl is not a water-tight object. It looks like the end cap
tessellation does not match the tessellation of the cylinder body.
Attached is an image showing this where we are looking down the
cylinder from one end. Note that parts of the end cap sticks out past
the cylinder.

Why does this matter? The signed distance computation from a query
point on one polydata to another finds the closest point on the other
polydata, then computes the dot product of the surface normal at the
closest point with the vector in the direction from the query point to
the closest point. The dot product determines the sign of the
distance, positive if outside the queried object, negative if inside.
Since that little part of the end cap sticks out past the side of the
cylinder, it is closer to the query point than the side of the
cylinder, the normal of the end cap at that point is used as the
surface normal. This causes the dot product for that query point to be
the sign opposite of what it would be if a point on the cylinder wall
was selected, hence the missing triangles.

My recommendation is to make your cylinder end cap tessellation match
the cylinder body tessellation and give this a try again.

Thanks,
Cory

Subject: [vtkusers] Problems with multiple vtkSphereWidgets
Message-ID: <1412886722189-5729098.post@n5.nabble.com>

Hi,

I have an application where I place sphere widgets to mark points in a 3D
volume. Whenever I slice through the volume, I change the visibility of the
widgets by turning them on and off. It works fine if there are only 1 or 2
widgets. However, once the number of widgets go up, the slicing becomes real
slow. Has anyone else come across this problem? Can anyone suggest a
solution?

Thank you.
Rahul.

Subject: [vtkusers] Change mouse cursor while hovering on vtkSphereWidget
Message-ID: <1412888586008-5729100.post@n5.nabble.com>

Hi,

I want the mouse cursor to change to a 'hand' when the mouse is hovering
over a vtkSphereWidget. 
Is there any out of box solution for this or do I need to subclass? I tried
using vtkSphereWidget2 and setting ManagesCursorOn() to true but that did
not help.

I see that the vtkAngleWidget exhibits the said behavior when mouse hovers
above one of the three control points which in my understanding are
vtkHandleWidgets.

Any suggestions??
Thanks

Rahul,

VTK does not perform well with many actors, so if you have a separate
vtkActor for each sphere, performance can get very slow.

You might want to try vtkGlyph3D with your marker points set as the input.

See http://www.vtk.org/Wiki/VTK/Examples/Cxx/Filtering/Glyph3D for an
example of how this is done with box glyphs. You can change the
vtkCubeSource to vtkSphereSource for your application.

Hope that helps,
Cory

I think you will have to subclass vtkSphereWidget2 and override the
SetCursor() method. The SetCursor() method for vtkHandleWidget is

//-------------------------------------------------------------------------
void vtkHandleWidget::SetCursor(int cState)
{
  if ( this->ManagesCursor )
    {
    switch (cState)
      {
      case vtkHandleRepresentation::Outside:
        this->RequestCursorShape(VTK_CURSOR_DEFAULT);
        break;
      default:
        this->RequestCursorShape(VTK_CURSOR_HAND);
      }
    }
}

I imagine you would want the same in your subclass.

HTH,
Cory

Subject: [vtkusers] vtkPolyData projected to a 2D plane,
	and then outlined/silhouetted...
Message-ID: <CAKME8fEATO1ht1eOOkznJULZN+hNeXekZEKsHde1ik5mBibPXA@mail.gmail.com>

Is there already a VTK filter that does this? I can't seem to find
just the right thing, and I don't want to write it unless I really
have to.

What I want is a filter that projects all the points of a polydata to
a 2D plane, and then connects the set of outermost points to produce
the outline of the projected polydata - like a shadow of it... (the
output should be another polydata which is a single closed polygon, or
the line segments that make up such a polygon.)

I tried vtkPolyDataSilhouette, which is close, but it's still a 3D
polydata, and it does not produce a closed outline.

Does anybody know the name of a filter that will do this?


Thanks,
David C.

David,

I don't know a filter that does exactly what you want, but could you
just take the output of the vtkPolyDataSilhouette filter, scale the
z-axis by 0 with vtkTransformPolyDataFilter, then run vtkCleanPolyData
on the output to get a closed 2D outline?

I get the following error : The file myPath/Kitware.dll is not valid

I saw a similar post but with no solution posted. Any help will be
appreciated.

Use the 32-bit x86 version for design mode in Visual Studio. VS is a
32-bit app, and can only load 32-bit (or "Any CPU") controls... Since
the x64 is a 64-bit only control, it cannot work within the 32-bit
Visual Studio environment.

Once you have a project that works as 32-bit, you can easily build a
64-bit version of it.... but inside VS you always need a reference to
the 32-bit one for things to work as you expect.

David C.

I dont have experience with subclassing vtk classes yet. Is there any other

Subject: [vtkusers] Overhaul of the rendering subsystem in VTK: Volume
	Rendering update
Message-ID: <CAEw35Z_0PxqjioJ4gD7vQtgP5sf5bUmoj-ppnmUTAwCbnMAshw@mail.gmail.com>

Friends,


As reported back in July, we are in the process of a major overhaul of the
rendering subsystem in VTK. The July article (
http://www.kitware.com/source/home/post/144) focused primarily on our
efforts to move to OpenGL 2.1+ to support faster polygonal rendering.  The
October Source will contain an article focused on our rewrite of the
vtkGPURayCastMapper class to provide a faster, more portable and more
easily extensible volume mapper for regular rectilinear grids.



VTK has a long history of volume rendering, and unfortunately that history
is evident in the large selection of classes available to render volumes.
Each of these methods was state-of-the-art at the time, but given VTK?s 20+
year history many of these methods are now quite obsolete. One goal of this
effort is to reduce the number of volume mappers to ideally just two - one
that supports accelerated rendering on graphics hardware and another that
works in parallel on the CPU. In addition, the vtkSmartVolumeMapper would
help application developers by automatically choosing between these
techniques based on system performance.



In this first phase, we have created a replacement for vtkGPURayCastMapper.
Currently, this is available for testing from the VTK git repository (in
master branch, disabled by default). General instructions on how to build
VTK from the source is available at this URL:
http://www.vtk.org/Wiki/VTK/Git*. *In order to build the new mapper, enable
the Module_vtkRenderingVolumeOpenGLNew module in cmake (via -D
*Module_vtkRenderingVolumeOpenGL=ON*), in ccmake or cmake-gui. Once built,
it can be used via vtkSmartVolumeMapper or used directly. Once sufficient
testing by the community has been performed, this class will replace the
old vtkGPURayCastMapper.  In addition, we are adding this new mapper to the
OpenGL2 module.  Availability of the new mapper with OpenGL2 module will
improve the management of textures in the mapper and eventually benefitting
both forms of rendering (geometry and volume) by sharing common code
between them.


Please contact us if you have any questions or encounter any issues.


Thanks,

Alok,

What I usually do is copy and paste an existing class and then modify
it appropriately, e.g., renamed the class, change the parent class,
remove unneeded member variables, methods, change the comments for the
class, etc. In your case, I would copy the vtkSphereWidget2 class to a
new class (vtkSphereWidget3?) and copy in the implementation for
SetCursor() in vtkHandleWidget, then be sure to declare this method in
your classes header file.

Hi Cory,

Thank you very much for your response. The reason I chose to go with
vtkSphereWidget was that I wanted interactivity with each point.

Rahul.

Sebastian,

Perhaps in your problem code, you could invoke one of the
SetInputArrayToProcess() variants on your vtkImageResliceMapper:

http://www.vtk.org/doc/nightly/html/classvtkAlgorithm.html#a6bea16e1329609dbccce0ff8d2367484

I believe the name of the scalars in the output of
itkImageToVTKImageFilter is "scalars".

Subject: [vtkusers] Extracting "feature surfaces" in VTK
Message-ID: <CAEhu9hBt+qt3btdZyXB-VdhyPATuC6BD=2uPm99GXhameb43fg@mail.gmail.com>

Hello all,

I'm trying to extract feature surfaces (e.g. inlets, outlets, etc.) in VTK
as briefly described in this fairly old mailing list exchange
<http://public.kitware.com/pipermail/vtkusers/2000-December/005137.html>,
but since I'm inexperienced with VTK, I need a little more detail.

I've tried the corresponding filters in Paraview, which was pretty
straightforward, but I'd like to be able to do it in VTK, which seems a lot
less straightforward.  The sequence of filters in Paraview that I used is
(starting from an unstructured grid volume) :

1. Extract Surface
2. Generate Surface Normals
3. Connectivity
4. Threshold (for each surface)

I believe the corresponding filters in VTK are:

1. vtkGeometryFilter
2. vtkPolyDataNormals
3. vtkPolyDataConnectivityFilter (or vtkConnectivityFilter)
4. vtkThreshold

I'm currently having trouble with the connectivity filters.  In Paraview,
the connectivity filter conveniently adds a "RegionId" array to the data,
which can then be used to separate the surfaces using the Threshold filter,
but this doesn't seem to be the case in VTK.  If I print the output of the
connectivity filter, there are no new arrays.  I believe the filter is
working though since GetNumberOfExtractedRegions() gives 3 (1 inlet, 1
outlet, 1 wall).  This brings me to a few questions:

   1. Is there a way to access each individual region?  And if so, is
   vtkThreshold even necessary?
   2. Is there a way to get the "RegionId" array in VTK and add it to the
   data?

I also had a question about how the connectivity filter works.  The Feature
Angle option in Generate Surface Normals dictates which edges of the object
that are rendered and seems to change the calculated point normals, but not
the cell normals.  Are these edges actually stored anywhere or are they
just implicit in the calculated point normals?  And the description for the
connectivity filter suggests that it simply looks for shared points between
cells, which doesn't seem like it would be affected by calculating point
normals.  So what does it use as criteria for separating surfaces when
performed after Generate Surface Normals/vtkPolyDataNormals?

Thanks,
Evan Kao

Subject: [vtkusers] Missing update extent request in vtkExtractVOI?
Message-ID: <54391E4E.8050907@student.hpi.uni-potsdam.de>

Hi everyone,

I tried to use vtkExtractVOI to decrease the resolution of a 
vtkImageData/vtkStructuredPoints data set. This works fine when I set 
the sample rate before I connect the filter to the pipeline. But 
changing the sample rate while rendering always results in an error like 
this:

"ERROR: In 
..\..\..\Common\ExecutionModel\vtkStreamingDemandDrivenPipeline.cxx, 
line 857
vtkCompositeDataPipeline (0000000005D6E1A0): The update extent specified 
in the information for output port 0 on algorithm 
vtkExtractVOI(0000000005D92710) is 0 10 0 10 0 0, which is outside the 
whole extent 0 9 0 10 0 0."

This behavior also depends on the initial sample rate. With the defaults 
(1, 1, 1), the error message pops up after changing the rate, and the 
filter seems produce the expected result. When I set different initial 
values and increase them while rendering, I get the error message above, 
but the filter result seems correct. When decreasing the sample rate, I 
don't get an error, but the filter decreases the size of the rendered 
image.

I'm using the current VTK master. I appended a small example the 
produces this error; it doesn't render any visible points but I didn't 
know how to enforce the required updates without adding the filter to a 
rendering pipeline.

BTW the error also occurs with vtkStructuredGrid+vtkExtractGrid.

Thanks,
Karsten

Subject: [vtkusers] QVTKWidget and Interacting with Image
Message-ID: <4FF6C7E8-0F23-45FF-8F56-6FBEF4A04AD8@gmail.com>

VTK Users,

 I would like to take the example for visualising a DICOM series in VTK (http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/ReadDICOMSeries) as outlined in the example I have linked to, but I want to render this within a QVTKWidget.

I have quite happily rendered the DICOM series in a QVTKWidget and can scroll through the image slices using something like a QSlider widget. But I simply cannot determine a way to interact with the image in the same way as the example shows, effectively being able to scroll through the images use the mouse wheel. 

There seems to be a lack of documentation of how to interact with the rendered window with a QVTKWidget and I hoped that someone with experience of this can advise on how I can interact with the image (as per the example I linked to above) but when it is rendered within the QT widget.


Regards, Nick.

Hi Sebastian,

Your first email said that the error is coming from vtkOpenGLTexture.
Are you using vtkTexture anywhere in your code?  Or maybe the
vtkTextMapper, which uses vtkTexture for rendering text?  You can
test by temporarily removing all actors from your program that display
tex to see if this stops the error.  The vtkImageResliceMapper itself
does not use vtkOpenGLTexture, so it cannot be the source of the error.

 - David

I just realized that calling SetUpdateExtentToWholeExtent() on a 
downstream algorithm (polyData in the example code) "fixes" this error.

I combined the 3 parts' polydata with vtkAppendPolydata and got rid of the
vtkAssembly which helps with performance but that leads me to another issue
with texturing:

One of the three cylinders of the previous assembly had a texture applied
to it. Combining the polydata and applying texture applies the image to the
entire cylinder rather than the smaller section.

Given a Cylinder - Is there a way to apply a texture to only a portion of
it's surface -- for example the bottom half?

Subject: [vtkusers] intersection of two actors
Message-ID: <CA+bBkNd68gOiQxoWGHnVM6SJW72-evLf-0UqqZDOoLheGO0XRg@mail.gmail.com>

Hi all,

I try to indicate the intersection region of 2 different actors I have used
poldydata filter to draw the intersection (intersection is a actor too).
But i couldn't make it dynamic. When i move the actors to different
positions, intersection actor's initial state remains same. How can i
create intersection actor and change it dynamically?

Thank you.

We completely rewrote vtkExtractVOI a few months ago and it doesn't look
like we didn't do a great job in fully evaluating it. I will spend some
quality time with it in the next few weeks.

It sounds like you have three vtkActors, one for two polydata and one
for the intersection of the polydata. You don't say how you are moving
the actors, but I assume you are calling the SetPosition() method on
the actors to move them. If that's the case, it's important to know
that this translation only affects the apparent position of the
actors, not the positions of the underlying data. Hence, your
intersection is not being updated because your polydata objects aren't
changing.

Instead, you need to change the actual positions of the polydata with
a filter such as vtkTransformPolyData. Then the output of
vtkTransformPolyData should be set as the input to  the intersection
filter (I assume you are using vtkIntersectionPolyDataFilter) and the
vtkMappers that feed into the actors.

Hope that helps,
Cory

Message-ID: <20141013165159.680A744825E@nhs-pd1e-esg103.ad1.nhs.net>

VTK'ers

I have multiple DICOM datasets with different spacing and dimensions. I am using vtkImagePlaneWidget() to view them

 I want to resample the datasets so they occupy the same volume in space, to then use e.g. vtkImageBlend to merge the images by opacity. I have tried vtkImageResample and vtkImageReslice (in the documentation for this class it even mentions the method SetInformationInput() as the way to go for matching voxel sampling. However whatever I try still results in the final output having image slices of different scales on the screen. Could anyone guide me as to what pipeline to use with  to get the datasets aligned?

Hi,

I sub-classed vtkAbstractWidget and created a vtkSphereWidget3.
 It seems to be working as expected when I use it in this example :
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/SphereWidget2

I think that 'mouse cursor change on hover' feature is a desirable one
since it indicates to the user that interaction with a sphere is possible
and expected.

I would like to know how I can commit this piece of code for review and
inclusion into the vtk repository.

Thanks

Hi Jamie,

Have you verified that the image data produced by the reader has the
correct spacing, i.e. the same spacing as specified in the DICOM
metadata for your files?  You should definitely verify that the reader
is producing accurate data before investigating the rest of the
pipeline.  As long as the spacing is correct, VTK should at least be
able to display the images with the correct relative scale.

The vtkImageResize and vtkImageResample filters do not change the
physical size of the images, they just change the spacing between the
data samples.  If the image was 150mm across before resampling, it
will still be 150mm across after resampling.  The way to change the
physical size of an image (and to perform alignment) is to provide a
ResliceTransform for vtkImageReslice.  Note that when I say "physical
size" I mean size in mm, not size in voxels.

I have tried vtkImageResample and vtkImageReslice (in the documentation for this class it even mentions the method SetInformationInput() as the way to go for matching voxel sampling. However whatever I try still results in the final output having image slices of different scales on the screen. Could anyone guide me as to what pipeline to use with  to get the datasets aligned?

Hi Nick,

can you post some of your source code showing how you set up the QVTKWidget with
the vtkImageViewer2, if you use that class?  Have a look at the
documentation for vtkImageViewer2 as
well as the source code.  I expect you may not be initializing the

Hi Nick,

I would set up the rendering environment first before setting any data inputs:
in TestInterface.cpp, get the vtkRenderWindow from your QVTKWidget, and
get its vtkRenderWindowInteractor:

vtkRenderWindow* renwin = ui->vtkWidget->GetRenderWindow()

//get the windows interactor:

vtkRenderWindowInteractor* iact = renwin->GetInteractor();

//set your custom interactor style

iact->SetInteractorStyle(myInteractorStyle);

// init the image viewer:

 imageViewer->SetRenderWindow(renwin);
 imageViewer->SetupInteractor(iact);


then set up all your other mappers and actors
and finally,

imageViewer->SetInputConnection(reader->GetOutputPort());

let me 9and vtkusers cc'd) know if that worked

regards,
Dean

Hi David,

Thanks for your insight. Yes without applying a reslice transform all I was managing to do with vtkImageReslice was pad the bounding box with zeros or chop off part of the data when I was attempting to align the datasets.

So I have to apply SetResliceTransform() to vtkImageReslice passing in a vtkAbstractTransform to go from one coordinate space to the other. I will only require a linear transform as there shouldn't be any deformation between them. I have the origin of both datasets (0,0,0), the spacing of the voxels in each dataset and the dimensions of the images. Could you tell me what kind of transform I should be applying to shrink one dataset (or expand the other) so they match? Or a reference to documentation would be helpful

thanks

Hi Jamie,

Have you verified that the image data produced by the reader has the
correct spacing, i.e. the same spacing as specified in the DICOM
metadata for your files?  You should definitely verify that the reader
is producing accurate data before investigating the rest of the
pipeline.  As long as the spacing is correct, VTK should at least be
able to display the images with the correct relative scale.

The vtkImageResize and vtkImageResample filters do not change the
physical size of the images, they just change the spacing between the
data samples.  If the image was 150mm across before resampling, it
will still be 150mm across after resampling.  The way to change the
physical size of an image (and to perform alignment) is to provide a
ResliceTransform for vtkImageReslice.  Note that when I say "physical
size" I mean size in mm, not size in voxels.

I have tried vtkImageResample and vtkImageReslice (in the documentation for this class it even mentions the method SetInformationInput() as the way to go for matching voxel sampling. However whatever I try still results in the final output having image slices of different scales on the screen. Could anyone guide me as to what pipeline to use with  to get the datasets aligned?

Subject: [vtkusers] Volume Rendering
Message-ID: <CACMHz4fndC1moVWxABLF+FuV8gtAFDTQgWDiNNdDc2nK3krhXQ@mail.gmail.com>

I am using vtkSmartVolumeMapper to render a volume and it is only rendering
a portion of the volume when the volume is not moving. When I click to
rotate the volume, the entire area of interest becomes visible, but as soon
as I stop the rotation, the majority of the volume disappears. Has anyone
encountered an issue like this before? Previously I was getting an error
about using more than one thread causing inconsistent rendering from
vtkFixedPointVolumeRayCastMapper but have since forced it to use only one
thread and the problem persists. My rendering code is below.

vtkSmartPointer<vtkRenderer> aRenderer =
    vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renWin =
    vtkSmartPointer<vtkRenderWindow>::New();
renWin->AddRenderer(aRenderer);

vtkSmartPointer<vtkRenderWindowInteractor> iren =
    vtkSmartPointer<vtkRenderWindowInteractor>::New();
iren->SetRenderWindow(renWin);
vtkSmartPointer<vtkImageData> testImage;
testImage = mrc.GetRegionImageDesc();

vtkSmartPointer<vtkSmartVolumeMapper> volumeMapper =
vtkSmartPointer<vtkSmartVolumeMapper>::New();
volumeMapper->SetBlendModeToComposite(); // composite first
volumeMapper->SetInputData(testImage);

vtkSmartPointer<vtkVolumeProperty> volumeProperty =
vtkSmartPointer<vtkVolumeProperty>::New();
volumeProperty->ShadeOff();
volumeProperty->SetInterpolationType(VTK_LINEAR_INTERPOLATION);
volumeProperty->IndependentComponentsOff();
vtkSmartPointer<vtkPiecewiseFunction> compositeOpacity =
vtkSmartPointer<vtkPiecewiseFunction>::New();
compositeOpacity->AddPoint(0,0.5);
compositeOpacity->AddPoint(254.0,0.5);
compositeOpacity->AddPoint(255.0,0.0);
volumeProperty->SetScalarOpacity(compositeOpacity);
vtkSmartPointer<vtkVolume> volume =
vtkSmartPointer<vtkVolume>::New();
volume->SetMapper(volumeMapper);
volume->SetProperty(volumeProperty);
vtkSmartPointer<vtkCamera> cam3D;
cam3D = vtkSmartPointer<vtkCamera>::New();
cam3D->SetViewUp (0, 0, -1);
cam3D->SetPosition (0, 0, 1);
cam3D->SetFocalPoint (0, 0, 0);
cam3D->ComputeViewPlaneNormal();
cam3D->Azimuth(30.0);
cam3D->Elevation(30.0);
cam3D->ParallelProjectionOn();

aRenderer->AddViewProp(volume);
aRenderer->SetActiveCamera(cam3D);

Subject: [vtkusers] How to prevent out-of-memory crash with vtkImageReader
	from Java
Message-ID: <CAFoCWhsqP03sFMwSO5vc4pAKjf5qDYmKOwCmy7tz8T-__kANrA@mail.gmail.com>

Hi all.
In my VTK-based Java application, I am reading a "raw volume file"
(containing a set of CT slices) through some Java code looking like this:

[...]
vtkImageReader imageReaderVTK =  new vtkImageReader();
imageReaderVTK.FileLowerLeftOn();
imageReaderVTK.SetFileDimensionality(3);
imageReaderVTK.SetFileName(curRawVolFile.getAbsolutePath());
imageReaderVTK.SetDataExtent(0, sliceCols - 1,
                      0, sliceRows - 1,
                      0, numOfUsedImages - 1);
imageReaderVTK.SetDataSpacing(xSpacing, ySpacing, zSpacing);
imageReaderVTK.SetDataOrigin(0.0, 0.0, 0.0);
imageReaderVTK.SetDataScalarTypeToUnsignedShort();
imageReaderVTK.SetDataByteOrderToBigEndian();

// The following call may cause a process crash due to out-of-memory
imageReaderVTK.UpdateWholeExtent();
[...]

I am then passing this volume to a vtkImagePlaneWidget for some reslicing.

As the last comment (in the code fragment above) suggests, in some cases I
get a crash of the JVM process, due to the fact the reader goes out of
memory while actually reading and allocating the whole volume in memory.
This especially happens when using a 32-bit JRE.
I understand that I cannot read a huge volume in memory if just a small
amount of memory is available to the process, but my question is:
is there a way to manage "more gracefully" this out-of-memory from Java
code, in such a way to be able to inform the user that "Not enough memory
is available to read this volume", instead of causing a JVM crash?

I am using VTK 6.1.0.

Thanks for any hint/suggestion about this topic.

Best regards,

Marco

Hi,

I am facing the same problem on Linux + Intel graphics card, it apparently
works with nvidia graphics cards
I tried on Windows and Mac OS: it works fine.

A simple example using only a VTK scene: rendering is fine.
Same example using QVTKWidget failed.

Any idea ?

Thanks.

Hi Marco,

I don't have the answer but if there is no solution as today, maybe adding
another method on the reader that could first validate that enough memory
is available, might be an option. Specially in Java when such call make the
JVM crash.

That change will need to happen on the C++ side. But at that point I'm not
sure how to check that on the C++ side either. Maybe Berk, Dave or Brad
might have some insight.

Thanks,

Seb

Hi Cory,
I tried by matching the  cylinder end cap tessellation with the cylinder
body tessellation. I have got rid of some of the big triangles which were
missing. Still, I have few holes at the intersection of the two surfaces. I
have attached the input files and images showing the behavior.

Hi again,

Yes you are right. We have three vtkActors, two Spheres and one for
intersection of Spheres.

We move actors with using keyboard interaction. We use TrackballActor.

In this case, does translation only affects apparent postion of the actors?

So how can we use vtkTransformPolyData and keyboard interactions together?

Hi,

I have an understanding problem, I think I am missing something.
what is a span iterator within the vtk image iterator? what is it needed
for?
I need to only iterate over an extent in the image and access data values
within it. How should I move the iterator to the next position? how to
access
the underlying data?

thx

Hi Zein, attached is the example I have modified (there are some errors in
the wiki example). In TestImageInterpolator.cxx you can see that there are
2 loops one for spans and the inner along the span. If you execute the
example you should obtain the following output. In this sample image there
two slices with size 4x3.

val: 0 0 0 0
val: 0 0 0 0
val: 0 0 0 0
val: 1 1 1 1
val: 1 1 1 1
val: 1 1 1 1

best regards,


Jorge

Friends,

As referred earlier, we are continuously working on improving the volume
rendering. As part of next set of delivery,  we are going to bring our
first OpenGL2 volume mapper to the OpenGL2 backend.
We have a branch that will get merged today and* it should only affect the
dashboards and code base switched to OpenGL2 backend*. We will continue to
improve the integration and will use and improve the
existing OpenGL2 backend code as necessary.

If you have any questions of concerns or if you find in any ways its
affecting your regular builds that uses OpenGL(default, and not OpenGL2)
 backend then let us know as soon as possible.

Thanks,

Subject: [vtkusers] using vtkPlaybackWidget in Python code
Message-ID: <CAMEnOB+FgNsBwb-aeG5Lr2Ab25V9ZyWA6-4RcO4-JqHEQH+ahQ@mail.gmail.com>

Hello,

I have written a Python application that relies on VTK to do some
scientific visualization. I would like to use the vtkPlaybackWidget
but I have the impression that the Python binding is useless. I am
supposed to override the virtual methods in the
vtkPlaybackRepresentation base class, but the Python bindings do not
allow that. I thought to add an observer that reacts to the
"EndInteractionEvent" when the widget is clicked, but I cannot figure
out how to extract the coordinates of the clicked point. Can anyone
please help me?

Cheers,
Davide

Hi Ilhan,

First of all, you should write a class that inherits the TrackballActor
class. Then you should override the Execute() function to have a full
control of your interaction. With this kind of implementation you should
assign another key(s) for example move actors left, up, right or left. 

Do the necessary calculation of your actors ( with calculating their world /
display coordinates to extract the intersection of spheres ) and finally
update / set your actors position and do not forget to call the Render()
function of your vtkRenderWindow instance.

I'm rendering a shape using vtkPolyData, i.e. as a collection of polygons.  Is there a way to colour each polygon separately?

polygonPolyData = vtkSmartPointer<vtkPolyData>::New();
polygonPolyData->SetPoints(points);
polygonPolyData->SetPolys(polygons);
hexmapper = vtkSmartPointer<vtkPolyDataMapper>::New();
hexmapper->SetInput(polygonPolyData);
hexactor = vtkSmartPointer<vtkActor>::New();
hexactor->SetMapper(hexmapper);

ren->AddActor(hexactor);

Thanks

Thanks Bill.  Following David Gobbi's suggestion, I got something working in a similar way to the ColorCellsWithRGB example.  But I can't say I fully understand it.  Specifically, I don't see why this statement

  aPlane->GetOutput()->GetCellData()->SetScalars(cellData);
or in my code
  polygonPolyData->GetCellData()->SetScalars(colors);

sets the colours.  How is it that the vtkUnsignedCharArray is interpreted as providing colours?

Cheers
Gib

Hi Gib,

VTK's mappers treat unsigned char scalars as a special case because long ago colors had to be sent to the rendering API as 3-tuples of red, green, and blue unsigned char values. The VTK mappers are hardwired to deal with this case.

Hi Richard, Ryan,

I have modified vtkPolyDataToImageStencil so that it works with the data
sets that you provided (thanks for making them available to me).  Richard's
data used to fail because it had several short horizontal line segments,
and there was a bug in the code when horizontal line segments were close to
a pixel boundary.  Ryan's data set had some short "spurs" (tiny line
segments branching off of the main contour) that confused the algorithm,
but I've extended the algorithm so that it removes short branches.

The most recent code is at the following URL.  It will hopefully be merged
into VTK sometime this week.  Thanks again for the test code and the data,
it made it much easier for me to pinpoint the bugs.

Thanks David.

I have tested and it?s working great.  Also, the overall speed of my program is much faster since I no longer have to use vtkCleanPolyData.

Hey vtk-users,

Sorry if the above is a bit long-winded.  It pretty much boils down to a
couple questions:

1. How do I extract each individual surface created by
vtkPolyDataConnectivityFilter?
2. How are the edges created by vtkPolyDataNormals stored in the poly data
object?

Thanks,
Evan Kao

Hi Evan,

I think that you can make vtkPolyDataConnectivityFilter generate the
RegionId array by calling ColorRegionsOn().  After that, the threshold
filter should be able to separate the regions.

Thanks for confirming that the fix works.  Out of curiosity, was your
contour produced by a VTK filter? (e.g. vtkCutter, vtkContourFilter,
etc.).  Or did you read it into VTK directly?

Yes.  I read in an STL surface using vtkSTLReader and then cut with a plane it using vtkCutter.

Message-ID: <CACQMks-HcG-H+UQ_hby1xYsCq3b_UCMfUR2mb3HoJ9O844cy5g@mail.gmail.com>

Hi all,

I try to compile this vtk project on
Qt:http://www.paraview.org/Wiki/VTK/Examples/Cxx/PolyData/TransformOrderDemo

I took many errors about vtkTransform. One of them:
C:\vtk\x64\6.0.0\install\include\vtk-6.0\vtkHomogeneousTransform.h:22:
error: C2027: use of undefined type 'vtkTransform' see declaration of
'vtkTransform'

I use qt 5.3.1 and 64 bit win7 os. I could successfully compiled the
project another computer. I suppose there is a problem with
vtkTransform.h library on my directory but I don't know what to do.

Thanks,
- Cem

That example compiles without errors for me with VTK_VERSION "6.1.0". Could
you try that version?

Should i update my VTK_VERSION to 6.1.0? May it be a problem with libraries
in the directory so i can find a solution depends on this?

That explains your issues. It is possible to configure with qmake, but
it will require that you provide proper includes and libraries. With
cmake it is much easier. Is there a reason you are using qmake versus
cmake?

No actually. Vtk had been configured by this way in the office where i
work. I think necessary includes and headers were provided in this example.
Is there anything to do using this environment? Thanks for all answers.

Hey,

This is a silly question.
I have been trying for a while to display a degree symbol in
vtkCornerAnnotation.

The way I am trying to do it is like this:
std;:string angle = computeAngle()+"\u00B0";
cornerAnnotation->SetText(3,angle.c_str()); //where cornerAnnotation if of
type vtkCornerAnnotation.

This displays something like 50A&circ&deg

In the past, VTK hasn't had very good Unicode support.  I'm not sure where it stands today actually.  What version of VTK are you using?  You'll have the best results with the newest version I expect.

Hi,

In VTK 5.10, I have only had success with vtkUnicodeString text arguments 
...

    std::ostringstream ostr;
    ostr << ang;
    vtkUnicodeString label(vtkUnicodeString::from_utf8( 
ostr.str().c_str() ));
    vtkUnicodeString deg( 1, 0xb0 );
    label += deg;

Not much help with vtkCornerAnnotation::SetText().

John.

I cloned the git repo some time time back and built from source
The vtkTextActor/vtkTextWidget seem to be working fine with unicode but I
see some other problems which make them unusable for me.

Any recommendations on how to check the difference between
vtkCornerAnnotation and the vtkTextActor will be great. Seems like an easy
fix

Thanks

Subject: [vtkusers] How to prevent out-of-memory crash with
 vtkImageReader from Java
Message-ID: <CAFoCWhvviAX4MLW5hHKWG9FNQYL5P6ooFQO03v=jP7D1WdWhsg@mail.gmail.com>

Hi Seb,

first of all, thanks for your feedback.

I have taken a look at the C++ code of vtkImageReader: it seems to me that
main allocation happens inside ExecuteDataWithInformation() method, which
in turn calls vtkImageData::AllocateScalars(), which in turn
calls vtkDataArray::CreateDataArray(), which finally I think ends up
calling ::New() on the typed data array (probably, vtkUnsignedShortArray in
my case).

If I were to write my own image reader, for instance, I am not sure how I
could detect eventual out-of-memory errors, since they would actually
happen inside other VTK classes. Maybe some try-catch blocks in my own
image reader may help me?
Any suggestion would be greatly appreciated.

I am looking forward to hearing from you.
Thanks and best regards,

Marco Sambin

Hi Marco,

I'm not an expert in that area, but if you try on your C++ end to allocate
the estimate memory amount and free it, you might be able to catch and
handle any kind of error feedback the way you want.

But also another approach which will be less exact will be to check what
remaining memory is available on the system and base on the file size,
pre-decide if that file will fit in or not. That option can probably just
live in Java. In fact, you can just let the user know, that loading such a
file may result of a crash as not enough memory might not be available.

Seb

Hi Alok,

As for the differences between vtkCornerAnnotation and vtkTextActor,
vtkCornerAnnotation uses the vtkTextMapper under the covers, which hasn't
seen as much attention lately as the other classes.

I don't have time at the moment to track down why the "\u00b0" literal is
getting garbled, but I did notice that using "\xb0" instead seems to be
work fine. It seems to be something screwy in the utf8 --> utf16 conversion
before rendering...

Try using "\xb0" instead and let me know if that works for you.

Hope this helps,
Dave

Friends,

Some more good news on the rendering side of things. In the last few days,
we have worked on porting two more volume mappers to OpenGL2 (FixedPoint
and Bunyk) and this noon we merged that code into VTK master. This change
should not affect the code that is using the OpenGL (and not OpenGL2)
backend. We will keep an eye on the dashboards and fix any issue that we
may find. Also, we have updated the vtkSmartVolumeMapper to deal with the
OpenGL and OpenGL2 backend.

Please let us know if you have any questions or if you encounter any issues
in the current master related to this change.

Thanks,

Message-ID: <s8e86c21.055@csir.co.za>

Hi Mirco

You could use vtkProgrammableGlyphFilter. There's a demo progGlyphs.tcl in the graphics directory

>>> Mirco M?ller <mirco at pool.informatik.rwth-aachen.de> 03/31 4:20 PM >>>
Greetings vtkusers-list!

    For the last couple of weeks I have been trying almost everything I
can think of to force vtkGlyph3D to use a two-colored line as glyph for
some vector values attached to some points. But the original colors
(gradient from blue to white) I set for the line (this is a vtkPolyData)
are always overridden by vtkGlyph3D. I simply cannot prevent vtkGlyph3D
to do a "color-by-scalar/vector/scale" sort of thing.

    I do not want vtkGlyph3D to act like this. Is there really no other
way than to customize the class vtkGlyph3D myself?

Thanks in advance for your time and kind advice!

Best regards...

Mirco

You may first read DICOM using this example:

http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/ReadDICOMSeries

and then blend (or fuse) them using this example:

http://www.vtk.org/Wiki/VTK/Examples/Cxx/Images/CombineImages

You may also need to resample (or more ideally register) them as well,
depending on your dataset and depending on what you want.

Hi,

Consider an instant of vtkTubeFilter which has a method named "SetRadius".
I was wondering how this Radius is related to millimeter?

I am using vtkTubeFilter as an example but in general I wanted to know how
units are involved in actors.

The VTK filters have no units.  It's the same as looking at the
equation y = m*x + b and asking what the units are:  all you can
tell for certain is that 'y' and 'b' have the same units, and that 'm'
has units of 'y/x'.  Other than that, it's up to whoever is using the
equation to decide on the units.  VTK is the same.

If you want to use millimeters, then set the radius in millimeters.
Just make sure that you use millimeters everywhere else, too.

Also make sure that all the files you load use millimeters.  If they
don't, you'll have to convert their units before you use them in your
pipeline.

Thanks David.
If a slice of DICOM is shown in 3D scene, and a tube actor is shown along
with it, now I am not sure how to set the radius of the tube to be actually
5 mm, because DICOM image is also present there in the same scene and DICOM
has a sense of unit.

Should I "calibrate" the unit of the Tube? For example, I may end up
concluding that if I set the radius of Tube to 1.4 then it is equal to 1 mm
in DICOM image.

Hi Sam,

You shouldn't have to perform any size calibration.  If you load a DICOM
file that uses millimeter units into VTK, then VTK ipso facto measures all
physical distances in millimeters.

If you have to set the radius to 1.4 in order to make it "fit" one
millimeter,
that suggests that the DICOM metadata has become corrupted somehow,
either before being loaded into VTK, or after being loading into VTK.

Make sure that the DICOM PixelSpacing is correct, and make sure that
the after the DICOM is loaded into VTK, that the image data "Spacing"
is also correct.

 - David

Thanks David.

OK. Then, if the actor is not coming from a VTK class such as
vtkTubeFilter, but instead it is coming from an STL file (for example it is
a model of catheter designed in SolidWork), then once this actor is shown
in 3D scene next to the DICOM slice, the size of the actor (which is from
the STL file) should make sense without having to be worried about any sort
of calibration (unless the DICOM is corrupted).

Did I get it right?

Hi Sam,

Yes, your summary is correct, with one caveat: the STL file format (unlike
DICOM) does not specify units, so you have to trust that whoever created
the file was using millimeters as their units.

Subject: [vtkusers] Structured Grid: strange view of surface+edges
Message-ID: <544CA161.4090000@img-online.de>

Hello,

I have a structured grid which seems to be well formed. If I load the 
vtk file with ParaView 4.2 some strange lines appear if the display mode 
surface+edges is selected. The modes surface, wireframe or points are 
looking good. I checked the data again and again. I cannot find any 
issue in the structured grid. I have attached the vtk file and some 
screenshots.

I also viewed the grid with a small python application using VTK 6.1.0. 
It shows the same behaviour as ParaView 4.2.

At the moment I do not have any idea how to go on. Any help is appreciated.

Michael

?Hi,


Need an experienced  cake and ccmake build master. Must be able to demonstrate skill set through a small problem we will assign to you before awarding the contract. This is a short term project that may lead to more work down the road. It requires linux (ubuntu) experience, CMake, CCmake, CTest, and C++ experience. You will be responsible for finishing the automation of the current semi-automated build environment on a linux server (ubuntu). To get the contract we will give you a  third party library that you will be responsible for building for multiple OS (linux mac, and windows) using cmake/ccmake, integrate the build environment with svn and integrate an automated QA process through CTest. More information will be provided once you have provide evidence of your skill set. We need for this work to be done in a very short time hence why you need to have prior experience the cmake environment.


Please reply to this email if you are interested.

Hi,

I downloaded
vtkpython-6.1.0-Windows-64bit.exe<http://www.vtk.org/files/release/6.1/vtkpython-6.1.0-Windows-64bit.exe>
and want to use it with Python 2.7
Where do I have to install VTK (or store ) ?
In the Python-folder in Lib/site-packages ? Or in an extra folder?
What else do I have to do before I can import vtk from a python script?

Thanks in advance!

Hi,

I want to export some data generated in Matlab into a vtk file format. I
want to visualize it using Paraview. The data in Matlab contains a grid and
some scalar values. The export works for the grid however the scalar values
are distorted and don't match their position on the grid. 

For the export I use an unstructured grid containing: points, cell-data,
cell-type (tetrahedron) and scalars. Does anybody know why the scalar values
don't match?

Without seeing your data or code, my first thought is that indexing in
MATLAB is based at 1 while VTK data structures are based at 0. Might that
be the source of the problem?

Thanks,

Hello, I want to read a vtkMultiBlockDataSet and append some more blocks 
(vtkPolyData). How do I have to extract the blocks from the reader and 
how can I add new blocks?



the (pseudo) code looks like this. Please have a look at the line with 
the red comment, the rest should be fine:


     vtkSmartPointer<vtkXMLMultiBlockDataReader> reader = 
vtkSmartPointer<vtkXMLMultiBlockDataReader>::New();
reader->SetFileName("vtkMultiBlockDataSetWriter_output.vtm");{
     reader->Update();

     vtkSmartPointer<vtkPolyData> linePolyData =
     vtkSmartPointer<vtkPolyData>::New();
     /* add some vtkLine to linePolyData */

     vtkSmartPointer<vtkMultiBlockDataSet> multiBDS_read = 
vtkSmartPointer<vtkMultiBlockDataSet>::New ();
     multiBDS_read->SETBLOCKS(reader->GETBLOCKS()); // HOW CAN I 
TRANSFER THE BLOCKS FROM READER TO MULTIBDS_READER?
multiBDS_read->(multiBDS->GetNumberOfBlocks(),linePolyData); // append 
one more block

     vtkSmartPointer<vtkXMLMultiBlockDataWriter> writer = 
vtkSmartPointer<vtkXMLMultiBlockDataWriter>::New();
     writer->SetFileName("vtkMultiBlockDataSetWriter_output.vtm");

Subject: [vtkusers] How to automatically update render when the input data
	is changed?
Message-ID: <1414421481476-5729250.post@n5.nabble.com>

Dear All,
  I have the following program

.h header file:
class SimpleView : public QMainWindow
{
      SimpleView();
  ~SimpleView();
       virtual void slotExecute();
     vtkSmartPointer<vtkRenderer> m_renderer;

}


.cpp source file:
SimpleView::SimpleView()
{
   m_renderer = vtkSmartPointer<vtkRenderer>::New();
   this->ui->qvtkWidget->GetRenderWindow()->AddRenderer(m_renderer);
   connect(this->ui->actionExecute, SIGNAL(triggered()), this,
SLOT(slotExecute()));
}

void SimpleView::slotExecute()
{	
    VTK_CREATE(vtkAssembly,stlAssembly);
    m_renderer->AddActor(stlAssembly);
    m_renderer->AddActor2D(scalarBar);   
}

So, slotExecute is triggered whenever I click the actionExecute button.
What I want to do is to update the m_renderer whenever the content of
stlAssembly is changed.
The problem is that m_renderer would add many vtkAssembly files and
scalarbar many times.

Message-ID: <CALm7otqHfPSmuC5nxd6TUVT3KYTbUb_78LiRrTAa6E4H0tx=xg@mail.gmail.com>

Hi,

1. In vtkLocal example I believe there is an error in the CMakeLists.txt:

find_package(VTK vtkCommonCore)

should be:

find_package(VTK 6.1 COMPONENTS vtkCommonCore)

or at least only so can I only configure the project using MSVC2012,
else I get a cmake error that vtkCommonCore is invalid/not found.

2. README says "Also add any VTK modules used by your classes to the
modules.cmake
  dependency list." Which modules.cmake do you mean? There is no such
file in VTK source tree.

Many thanks for clarifications.

Best regards,
Dominik

It's easy to add an actor that displays a cuboid with a wireframe
representation.

Is it easy to make that wireframe look "fuzzy" instead of a sharp line?

Hi guys,

I met a problem which confused me. I tried to specify the window size by
myself. But when I checked it later, the GetSize() always returned a value
a little bit different from what I set before. I put the code below. I only
called the renderwin to Render() before I checked the window size. It seems
the Render() changes the window size. But I don't get why is that. Does
anyone can help me about that? Thanks very much!

vtkSmartPointer< vtkRenderWindow > _imgRenderWin = vtkSmartPointer<
vtkRenderWindow >::New();
int _size[2] = { 700, 500 };
_imgRenderWin->SetSize(_size);
_imgRenderWin->AddRenderer(_renderer);
_imgRenderWin->Render();
int *_dim;
_dim = _imgRenderWin->GetSize();
int _dimx = _dim[0];
int _dimy = _dim[1];

Hi Lin,

Calling Render() should not change the window size, and in fact if it did,
then many of the nightly VTK tests would fail.  This means that there must
be something different about your computer as compared to the computers
that are used to test VTK.  So, the more information that you can provide
about your system, the better!

1) What operating system are you using (be as specific as possible)?
2) What version of VTK are you using?
3) What size did GetSize() return?  The exact numbers can be useful
  in figuring out what is causing the problem.
4) If possible, run "ctest" to test your VTK for other problems.

 - David

You mean fuzzy as in furry, or fuzzy as in blurry?  Or jittery?

If you want jittery, here's how you can add jitter to any VTK polydata:

Use a random point source e.g. vtkPointSource as the input to vtkGlyph3D,
and use your polydata as the glyph.  The output will be jittered polydata.

You might be able to make it look fuzzy by tessellating it and then
rendering
it as points.  For example: tessellate the frame, and then use it as the
input
to vtkGlyph3D while using random points from vtkPointSource as the glyph.

Subject: [vtkusers] Cast vtkTypedDataArrayIterator to vtkArrayIterator?
Message-ID: <F6320968-CD46-43D6-BF66-0BBADFC2F65A@ufz.de>

I have a similar implementation of a vtkMappedDataArray as in 

vtkCPExodusIIResultsArrayTemplate (https://github.com/Kitware/VTK/blob/master/IO/Exodus/vtkCPExodusIIResultsArrayTemplate.txx).

The mapped data array is part of a vtkMappedUnstructuredGrid as in

https://github.com/gahansen/Albany/blob/master/src/disc/catalyst/Albany_Catalyst_Grid.hpp

and so on. It works fine. Now I try to write the unstructured grid to a file which also works fine in binary mode. But when I switch the vtkXMLUnstructuredGridWriter to ascii mode the member vtkArrayIterator* NewIterator() of my vtkMappedDataArray needs to be implemented. I did not found an example of such an implementation. For now I came up with this:

template <class Scalar> vtkArrayIterator*
VtkMappedElementDataArrayTemplate<Scalar>::NewIterator()

Thanks for the ideas. We're just looking for a way to make a sharp outline
a little less "the focus of the scene" than it appears to be with the plain
old line rendering. We were thinking blurry or diffuse.

We'll give some of these a try.

David,

Channeling Tufte, it sounds like you have a case of chartjunk. Two
potential solutions:

1). Remove the chartjunk.

2). Use the thinnest lines possible and pick a color that contrasts just
slightly with the background.

HTH,
Cory

you probably want to make sure you get an opengl context that supports
antialiasing, used to be renWin->SetMultiSamples(1) prior to first render
so that you get the right context.

Hi Lin,

It looks like this was a problem with VTK 5 on Windows 8.
This was fixed in VTK 6.1, see the following patch:

Subject: [vtkusers] Cast vtkTypedDataArrayIterator to vtkArrayIterator?

Hi Lars,

The vtkArrayIterator class is very different from the
vtkTypedDataArrayIterator. See the APIs in vtkTypedDataArrayIterator.h and
vtkArrayIteratorTemplate.h. The former is an STL style iterator, while the
latter uses a custom API for retrieving data.

At this point, you'd need to write a new iterator implementation that
matches the vtkArrayIterator API and somehow shoehorn some extra logic into
vtkArrayIteratorTemplateMacro in vtkSetGet.h. This would be hacky, and to
properly fix this the writer would likely need to be rewritten, since the
vtkArrayIterator plumbing seems intrinsically tied to the
vtkArrayIteratorTemplate class, which relies heavily on the horrible
vtkDataArray::GetVoidPointer method.

Is ascii mode required for your use case? If not, it would likely be much
simpler to just use binary mode.

Hope this helps,
Dave

I have located yet another problem. My VTK 6.1 is built with python
wrapping, but when I build vtkLocalExample, no python wrapping is
performed, even though the README promises it being done
automatically. What is happening?
Thanks for any hints

Thanks for the further advice. It's actually an interactive widget that
allows the user to adjust something temporarily, so I'm not convinced
chartjunk is quite right for it. ;-)

Jeff Lee: I thought we already were multi-sampling, but it's possible we're
not... I'll look into that first.

Thanks,
David C.

How about just making them translucent and increasing the line width a tad?

Dominik,

vtkLocal was overlooked back when modularization happened. There were some
recent fixes in master a few weeks ago that may fix the problems you see.

Subject: [vtkusers] display a thick shell of volume
Message-ID: <544FFB51.6060906@rhpcs.mcmaster.ca>

Hi VTK users,

I want to volume render (using 3D texture mapper) a shell with specified 
thickness. Previously, I used vtkClipVolume twice, one clipped away the 
inner portion of a regular volume data, the other clipped away outer 
portion. The only problem is slow rendering speed because the resultant 
data is no longer a regular volume data.

Can anyone suggest a better solution? Would it be faster if I used 
several spheres with texture mapped on them and alpha-blending? Thanks.

Best,
Weiguang

Hi Weiguang,

You definitely want to avoid using vtkClipVolume before volume rendering,
because it produces vtkUnstructuredGrid data instead of image data.

If you need a shell, you can use vtkImageGaussianSource to create an image
of a Gaussian, and then threshold it with lower and upper thresholds to
create a shell.  A Gaussian has radial symmetry, so thresholding will
create a binary image of a spherical shell.   You can then multiply this
shell by your image.

Or, instead of using vtkClipVolume, you can use
vtkImplicitFunctionToImageStencil with vtkImageStencil.  The output will be
a vtkImageData.  Or, for greater efficiency, use vtkROIStencilSource to
create a spherical (ellipsoidal) stencil for vtkImageStencil.

Or, possibly the easiest "quick fix" would be to convert the
vtkUnstructuredGrid that you already have into a vtkImageData by using
vtkProbeFilter.  The vtkProbeFilter is a generic filter for copying (or
interpolating) scalar data from one kind of data set onto another kind of
data set.

Hi David,

thanks a lot for your explanation! I already assumed that this would not be an easy task ...

But I found an easy workaround:

If I write ascii files then I deep copy the mapped grid to a regular vtkUnstructuredGrid and  write out this temporary. This fits our needs because ascii files will just be written out for debugging purposes and if the grid is relatively small.

Best,
Lars

This would be hacky, and to properly fix this the writer would likely need to be rewritten, since the vtkArrayIterator plumbing seems intrinsically tied to the vtkArrayIteratorTemplate class, which relies heavily on the horrible vtkDataArray::GetVoidPointer method.

Subject: [vtkusers] Multiple vtkPolygons in a vtkPolyData
Message-ID: <5F7A6891-FE79-48F9-972F-E9C292A6B723@gmail.com>

Dear VTK Users,
 
I have been having some trouble with handling polygons in VTK and hoped that someone can offer some guidance. 

I wish to do the following:-
1) Read some contours (structures) from a DICOM file - these are essentially polygons drawn on 2D slices.  ( I have completed this task and have the ability to extract the x,y,z point of each vertex from a DICOM RTStruct) There are approximately 250 polygons.

2) I want to add these coordinate positions to create a vtkPolygon

3) I want add each vtkPolygon object to a vtkPolyData 

4) Render the polygons. ( I can probably deal with this ).

Up until now I have been using the http://www.itk.org/Wiki/VTK/Examples/Cxx/GeometricObjects/Polygon example and trying to adapt it. 

Can anyone advise how I would modify this segment of code (taken straight from the code in the link above) so that it would be generic that I can add multiple independent polygons (in the example I am working with there are approximately 250 polygons) to the vtkPolyData.

vtkSmartPointer<vtkPoints> points =
    vtkSmartPointer<vtkPoints>::New();
  points->InsertNextPoint(0.0, 0.0, 0.0);
  points->InsertNextPoint(1.0, 0.0, 0.0);
  points->InsertNextPoint(1.0, 1.0, 0.0);
  points->InsertNextPoint(0.0, 1.0, 0.0);
 
  // Create the polygon
  vtkSmartPointer<vtkPolygon> polygon =
    vtkSmartPointer<vtkPolygon>::New();
  polygon->GetPointIds()->SetNumberOfIds(4); //make a quad
  polygon->GetPointIds()->SetId(0, 0);
  polygon->GetPointIds()->SetId(1, 1);
  polygon->GetPointIds()->SetId(2, 2);
  polygon->GetPointIds()->SetId(3, 3);
 
  // Add the polygon to a list of polygons
  vtkSmartPointer<vtkCellArray> polygons =
    vtkSmartPointer<vtkCellArray>::New();
  polygons->InsertNextCell(polygon);
 
  // Create a PolyData
  vtkSmartPointer<vtkPolyData> polygonPolyData =
    vtkSmartPointer<vtkPolyData>::New();
  polygonPolyData->SetPoints(points);
  polygonPolyData->SetPolys(polygons);


I hope my problem is clear, but am happy to clarify if you think you are able to offer guidance which would be much appreciated.

Regards, Nick.

Hello,

i have one more question: why does the following line work (see below 
for the context)?

multiBDS_read->ShallowCopy(reader->GetOutput());

why does ShallowCopy copies all the content to multiBDS_read (as 
compared to DeepCopy)?


thanks

Want to use vtkAxesTransformWidget class.

Added following code in Simple  C exe..

int main (int, char *[])

  // A renderer and render window
  vtkSmartPointer<vtkRenderer> renderer =

  // An interactor
  vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
  renderWindowInteractor->SetRenderWindow(renderWindow);
  
  renderWindow->Render();

  vtkSmartPointer<vtkAxesTransformWidget> axesTransWidget = 
vtkSmartPointer<vtkAxesTransformWidget>::New();
  axesTransWidget->SetInteractor(renderWindowInteractor);
  axesTransWidget->CreateDefaultRepresentation();
  axesTransWidget->On();

 renderWindowInteractor->Initialize();
  renderWindow->Render();
 
  renderWindowInteractor->Start();
 
  return EXIT_SUCCESS;
}


But getting following error at line " renderWindow->Render()"

You should be able to put all of the points and all of the polygons into
your existing "points" and "polygons" variables, and have just one polydata
that refers to all of them at once.

Or:

See this example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Filtering/CombinePolyData

And the documentation for the append and clean polydata filters:
http://www.vtk.org/doc/nightly/html/classvtkAppendPolyData.html
http://www.vtk.org/doc/nightly/html/classvtkCleanPolyData.html

The vtkAppendPolyData filter produces a single polydata output from many
input polydata objects.


HTH,
David C.

Hi Weiguang,

There aren't any filters for combining vtkImageStencilData (there should
be!), so instead you will need to use two vtkImageStencil filters in
series: one for the first vtkImplicitFunctionToImageStencil output, and
then another for the second.

Hi David,

How to combine the outputs from two vtkImplicitFunctionToImageStencil 
instances as I need to use two spheres to define a shell? Thanks.

Subject: [vtkusers] VTK widget "border" width
Message-ID: <1414608939269-5729287.post@n5.nabble.com>

Some quick background:
I have been developing a program that integrates VTK into a GUI designed
with Qt. Thus I have been using the QVTKRenderWindowInteractor for Qt
integration. Below is a code snippet that shows how I initialize all of the
VTK business.

class modelView(QMainWindow):
    ...
    
    def setupUi(self):

        ...

        self.frame = QFrame()
        self.frame.setLineWidth(0)
        self.frame.setFrameStyle(QFrame.NoFrame)
    
        self.vl = QVBoxLayout()
        self.vtkWidget = QVTKRenderWindowInteractor(self.frame)
        self.vl.addWidget(self.vtkWidget)
    
        self.ren = vtkRenderer()
        self.vtkWidget.GetRenderWindow().AddRenderer(self.ren)
        self.iren = self.vtkWidget.GetRenderWindow().GetInteractor()
    
        self.ren.ResetCamera()
    
        self.frame.setLayout(self.vl)
        self.setCentralWidget(self.frame)
    
        self.show()
        self.iren.Initialize()
        self.iren.Start()
    
    ...

Now for my actual question, it appears as though the render window has a
border around it. I.e. the outline is offset by some amount. The image below
shows what I am attempting to say. The top cropped image comes from a
different program written in Qt, the two left widgets are dockwidgets and
the right is a QGraphicsView (I think). The bottom image is cropped from my
program, the same setup but thee right widget is a VTK render window. You
can see the difference in "border width", if that's a thing.

My curiosity got the best of me, and I am now curious as to how this happens
and if you change it (it looks odd to me).

Subject: [vtkusers] pick vtkCell that is behind other vtkCells
Message-ID: <1414625568927-5729288.post@n5.nabble.com>

Hi, I've looked through past posts and saw a related post but no one replied
to it, so I'm making a new one.  

My problem is I have a finite element model with shell elements, bar
elements, and nodes.  I would like to be able to pick a shell element that
is behind other elements.  I've tried vtkCellPicker, but this only returns
the first cell that the ray passes through.

I would like to be able to pick from all cells that the ray passes through
and pick the cell whose center is closest to the ray.  Once the cell is
picked, I would like to highlight its edges.  This means if it is behind
other cells, I would like to force its edges to be drawn so that the user
can see them instead of them behind hidden due to being behind other cells.

I've made a workaround for both of these, but I assume there's a better way
of doing it.  I've created points at the center of all the cells and simply
used a vtkPointPicker, and then determined the corresponding cell.  I then
draw a new cell on top of the screen close to the camera to force it in
front of all other cells.  This seems like a bad hack and inefficient.

I'm pretty new to VTK.  I've searched through many examples and bought the
VTK User's guide, but haven't found anything that can help me with this.  If
it's in an example somewhere, I haven't been able to find it, or I simply
didn't recognize its applicability.

Any help would be greatly appreciated.  Thanks!

Subject: [vtkusers] How to vis normal vectors of polydata as arrows ?
Message-ID: <CALmrq1bGMApYa5Li_fqrtepPaXM-FDi5FWEjnLt096wfoKOmug@mail.gmail.com>

Hi all,

I'm trying to vis the normal vectos of polydata as arrows. Is there any
convenient way to achieve this? I read the example
http://www.vtk.org/Wiki/VTK/Examples/Cxx/GeometricObjects/OrientedArrow
here, but I still don't understand how to do this. It seems to vis one
arrow we need to follow quite a lot steps. I think my problem is the same
with

, though there is no answer below. :-(

Can anyone give me some advice? Thank you very much!

Dear David,

Thanks for getting in touch. I think this was a good starting point but still not entirely sure that it?s what I need. I created N slices of simple 2D squares, equally spaced on the Z axis - the it was like a stack of contours. But when I add the polygons and points to the vtkPolyData and then render using vtkPolyDataMapper it is one image, but the square slices are connected in some way? (please see the image attached). Realistically the slices are not attached, they are contours drawn on individual z-positions.

Ultimately I want to visualise DICOM images (transverse plane, effectively slice-by-slice) and on each individual slice I would want to overlay a contour/polygon which defines different organ regions. I would also want to be able to check if a voxel (from the dicom image) lies within the bounds of the polygon.

Would the approach of creating N independent vtkPolygon objects and then adding each on to a vtkCellArray be along the correct lines for doing this do you think?

Regards, Nick.

Also, this example:

contains much more than what you're asking for, but also does contain
exactly what you're asking for. Visualizing normal vectors with arrow
glyphs.

Thanks to Susan (<ghy at tellyes.com>), I was able to use
vtkCellLocator::FindCellsAlongLine to pick behind cells.  Thank you!

This leads me to the next part of my problem... how to choose the element
whose center is closest to the line?  I probably need to use vtkCellCenters? 
I wasn't able to figure that part out today, so I manually calculated the
centers and then found the closest cell.  I wouldn't be surprised if there
as a vtk method for this.

The last part of the problem is how do I highlight cells that are behind
other cells so that the highlight is visible to the user?  I currently draw
new edges on top of the screen close to the camera, but I doubt this is the
best method.

Thanks again!

Message-ID: <tencent_5EFE2F1527FD38EC66A4AD00@qq.com>

Hi all, 

I have used the vtkDijkstraGraphGeodesicPath class to find the shortest path between two points on a mesh, and my next step is to project the path(curve) to a planar. Is there a class or function in vtk to project curve to planar? And the other way is to sample the path(curve) and then project the sampled points to the planar, so how to sample the curve and get sampled points? Thank you in advance!?

Subject: [vtkusers] Represent particles (as a set of points) and associate a
 scalar to them?
Message-ID: <1414747923304-5729299.post@n5.nabble.com>

Hello.

I'm working on an old project, and the vtk format used is the legacy ASCII
one.
I need to display particles in ParaView, and the code already there
generates .particles files, which use the PARTICLES dataset. First of all, I
can't find anything on the Internet about that dataset. Second of all, here
is the content :

> # vtk DataFile Version 3.6.2
> Particle file, current time (s) = 1
> 
> DATASET PARTICLES
> POINTS 2 float
> 0.003 0.815 0.026
> 0.241 0.508 0.053
> 
> POINT_DATA 2
> SCALARS identity float 1
> LOOKUP_TABLE default
> 1
> 2

Now this looks good : it's two particles, represented by (x, y, z) values,
and each of them has a scalar `identity` associated.

However, when opening this in ParaView, I don't get 2 points, I get 4. Also
the values are all messed up, and I can't even color them according to their
`identity` value. So, it sucks. And since I can't find anything about the
PARTICLES dataset, I guess I shouldn't use it.

Can someone help me in any way ?

I have just started a PhD looking at a brain cancers. I am currently hoping
to create an applet that will display the areas of interest around the
cancer.

Just after surgery, the cancerous area is empty, so I was contemplating the
idea of doing edge detection of a CT DICOM to find where the air meets
tissue to visualise where the tumour was.

After I have found the volume, it should be simple enough to calculate the
centre of mass of the tumour. Following this, I think I would like to create
3 orthogonal cutting planes going through the brain so that the brain is
split into 8 parts, centered around the tumour.

I would hope to show this all as an exploded view so that I can display the
tumor, and the 8 other segments all side by side. I want to do this so that
I can run GATE simulations on the uptake of activity in the tumourous area
and the healthy sections touching it and see the results as a function of
colour.

Is this feasible?

If I haven't explained how I envisage the final visualisation, imagine a
peach - take out the stone and cut the rest into 8ths (half it, half those,
and half all those). I want to show the stone and the 8ths with specific
focus on the areas of the peach that were touching the stone.

Thanks in advance for the help

Try to change PARTICLES to POLYDATA in your file, and it should load.

See http://www.vtk.org/VTK/img/file-formats.pdf for details on the legacy
format.

Subject: [vtkusers] weird vtkXMLMultiBlockDataWriter segfaults in binary mode
Message-ID: <54541FD6.8050807@gmx.ch>

Hello VTK users and developers,

I attached a simple program which segfaults. please also have a look at 
the comments in the code.

i want to:
1) write a vtkMultiBlockDataSet to a file
2) load it
3) add some more Blocks
4) write it again

it only segfaults if the writers are set to binary mode, and only if the 
data exceeds a certain size. in ascii mode, everything is fine.


this might be related:
http://www.paraview.org/Bug/print_bug_page.php?bug_id=13294


can you confirm that behaviour? what am i doing wrong? and if it is a 
bug, how can i work around?

thank you very much
simon

Hey there,

I?ll try to go through you description:

> cancer.

Not sure how you envision said applet but if you?re referring to a web-applet then you could take a look at VTK Web or ParaviewWeb which you allow in-browser visualization of your scene

You could easily do some basic segmentation based on the CT Hounsfield units using thresholding in VTK and create labelfields and 3D surfaces (check this blog post on surface extraction: http://pyscience.wordpress.com/2014/09/11/surface-extraction-creating-a-mesh-from-pixel-data-using-python-and-vtk/ <http://pyscience.wordpress.com/2014/09/11/surface-extraction-creating-a-mesh-from-pixel-data-using-python-and-vtk/>). I can?t vouch for the availability or ease-of-use of advanced segmentation algorithms in VTK but ITK/SimpleITK has all that functionality (check this other blog post on SimpleITK and image segmentation: http://pyscience.wordpress.com/2014/10/19/image-segmentation-with-python-and-simpleitk/ <http://pyscience.wordpress.com/2014/10/19/image-segmentation-with-python-and-simpleitk/>). SimpleITK also allows you to load compressed DICOM data through GDCM which AFAIK VTK doesn?t.

That?s actually easy in VTK. After you?ve extracted the tumor surface as vtkPolyData (again, surface extraction) you can use vtkCenterOfMass to find that point. Then you just need 3 cross-sections through the vtkImageData (containing the DICOM data) through the vtkImageSliceMapper (check this gist ? haven?t written a blog post on that yet: https://gist.github.com/somada141/3d426b181ce202933950 <https://gist.github.com/somada141/3d426b181ce202933950>).

If you actually want to visualize the extracted surfaces as split you can clip them

> Is this feasible?

AFAI understand by your description I?d say a combination of VTK and ITK/SimpleITK gives you all the tools you need so I dare say it is feasible if not completely straightforward. You probably know better, but I was under the impression that after extravasation the tumor-hole is filled with cotton to soak up fluid so I?m not 100% sure you will get a clearly demarcated air-hole there. Segmentation might be a lil? more tricky then.

Anyway, good luck with the PhD, sound interesting :)

Cheers,
Adam
