Dear All,

I have a polydata that contains several connected components. I need only
the largest component in my polydata. What should I do and how I can use
Connectivityfilter to solve this problem



Thanks

It is a set of polygons that are connected.

Perhaps your data has some issues.

Subject: [vtkusers] Many vtkTexturedButtonRepresentation2D does not accept
 user interaction.
Message-ID: <1483383516106-5741673.post@n5.nabble.com>

Hi,
I have two renderes added in the same renderwindow. Use viewerport to
separate them.

I have two vtkButtonWidget using vtkTexturedButtonRepresentation2D as
impersonation.

When I add the 2 vtkButtonWidget, one on each renderer, the object that goes
into the second renderer does not accept user interaction.

Note that the mouse on the second renderer does not even change.

Below the code for compilation.


#include <vtkVersion.h>
#include <vtkSmartPointer.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>

	CreateImage(image1, banana, tomato);
	CreateImage(image2, tomato, banana);

	// Renderes and Window

	renderer1->SetViewport(0, 0, 1, .5);

		buttonWidget[i]->On();
	}


	renderWindow->Render();
	renderWindowInteractor->Start();

	return EXIT_SUCCESS;
}

				 unsigned char* color1,
				 unsigned char* color2)
{
	// Specify the size of the image data
	image->SetDimensions(10, 10, 1);
#if VTK_MAJOR_VERSION <= 5
	image->SetNumberOfScalarComponents(3);
	image->SetScalarTypeToUnsignedChar();
#else
	image->AllocateScalars(VTK_UNSIGNED_CHAR, 3);
#endif
	int* dims = image->GetDimensions();

Subject: [vtkusers] Issue; Number of Regions are equal to the number of Polys
Message-ID: <CAOE4DFWiufSmffowZMCr=80AoCfaF=59wCdvBRimk-qFhCDn2Q@mail.gmail.com>

Hi


I have a vtp file that contains a polydata. I want to extract its connected
component. However, when I use* vtkPolyDataConnectivityFilter**, *and read
the number of regions, it shows that the it is equal to the number of
polys. But when I visualize the file I see that there are actually 4
regions.

I use SetExtractionModeToAllRegions to read the number of regions.
I have attached the file. Can you please help me to understand what the
problem is

So here is my code

vtkSmartPointer<vtkPolyDataConnectivityFilter> connectivityFilter =
vtkSmartPointer<vtkPolyDataConnectivityFilter>::New();
    connectivityFilter->SetInputData(poly_in);
    connectivityFilter->ScalarConnectivityOn();

    connectivityFilter->SetExtractionModeToAllRegions();

    connectivityFilter->Update();
    int nbregions = connectivityFilter->GetNumberOfExtractedRegions();

    cout << "Number of Extracted Regions are=" << nbregions << endl;

Thanks

Apply vtkCleanPolyData first. The triangles in that data have points that
are coincindent, but none are actually shared across neighboring edges.
Clean will merge the coicident points for you.

Hi !,


I'm working on vtkContourWidget example with a .mha 2D binary image and I have one question :

How can I apply that example (attached file ) to my contour-1.mha image (attached file) ?

Thank you in advance.


Kind regards,


Abdelkhalek Bakkari

Subject: [vtkusers] vtkLight inside an opaque polydata object
Message-ID: <1483465561650-5741679.post@n5.nabble.com>

Hello,

I have a polydata object which is watertight, i.e. it fully encloses a 3D
region.  I make it opaque since I don't want its back wall to be seen on the
screen.

I would like to place a positional vtkLight inside the region enclosed by
the polydata, and control its direction and position programmatically to
highlight the region of interest for the user.  (The cone angle I have in
mind is about 5 degrees, and the shape of polydata is complicated - it's
definitely not convex).  It appears that since the polydata object is
opaque, this highlighting cannot be seen when viewing the polydata object
from outside.

How can I get the highlighted region to be visible when viewing from
outside?

Many thanks,

leonid

Subject: [vtkusers] SetInputData and extents
Message-ID: <B3A499C2-6024-4333-BEE2-0BFB2FAB9342@googlemail.com>

Hi All,

I have a custom datatype (myType) derived from vtkImageData and a custom filter derived from vtkImageAlgorithm. The filter takes input on two ports which are both myType objects with different sizes. 

So in principle I should be able to set these inputs using either SetInputData() or SetInputConnection() right? However, when I run the filter  I get errors like:

ERROR: In ?. /vtk/Common/ExecutionModel/vtkStreamingDemandDrivenPipeline.cxx, line 857
vtkStreamingDemandDrivenPipeline (0x7fc6fa444a00): The update extent specified in the information for output port 0 on algorithm vtkTrivialProducer(0x7fc6fa4444a0) is 0 31 0 0 0 0, which is outside the whole extent 0 5 0 0 0 0.

ERROR: In ?. /vtk/src/vtk/Common/ExecutionModel/vtkTrivialProducer.cxx, line 264
vtkTrivialProducer (0x7fc6fa4444a0): This data object does not contain the requested extent.

Any suggestions? Is there something I am missing here?

Dear All,


I have a Polydata and after cleaning I get a new mesh but the texture of
the me sh is corrupted. I guess the problem comes the fact that  the points
are merged. Do you have any Idea how to apply vtkCleanpolydata to the
VtkPoly data without corrupting the texture.

Message-ID: <2b92a01d266af$939ff790$badfe6b0$@vektore.com>

Hello vtkusers,

 

I am trying to compile my VTK 7.1 against OpenVR following the
documentation:
https://blog.kitware.com/using-virtual-reality-devices-with-vtk/

I got all modules  <https://wiki.libsdl.org/Installation> SDL2/
<https://developer3.oculus.com/downloads/> Oculus Windows SDK/
<https://github.com/ValveSoftware/openvr> OpenVR SDK and master branch of
VTK from the  <https://github.com/Kitware/VTK> VTK respository . I had used
CMAKE 3.0 as usual to compile everything against Visual Studio 2013, as well
my VTK 7.0, VTK 6.3.

 

The point is, every time I am trying do build the libraries by compiling my
VTK.sln within Visual Studio I got the following errors:

 

Error     871        error C2039: 'API_OpenGL' : is not a member of 'vr'

They changed the signature on a couple functions in a recent SDK update. I
have the changes at home and I'll push a topic soon to update it. If you
look at the OpenVR SDK header files you can see the new signature change,
it is a pretty easy fix. I'll try to remember to email the diffs tonight
when I get home.

Hi Ken,

 

I got some things regarding 'API_OpenGL' to TextureType_OpenGL within OpenVR SDK. However, there are other issues related to vtkOpenVRCamera, vtkOpenVRRenderWindow, vtkOpenVRRenderWindowInteractor

 

I am looking forward to hearing from you soon.

It can be done, but you'll need to keep all of the input data / pipeline
logic in a background thread, and all of the renderable polydata / mapper /
actor stuff in a rendering thread, and then synchronize the threads to copy
the data from the background -> rendering thread after an update completes.
This will let you interact with the scene while data is being recomputed.

I'm not sure what you mean by "are just in increasing order". Do you
mean that each triangle has a unique set of three vertices and the
vertices are listed in the order the cells are listed?

vtkCleanPolyData would be useful:

See this example that does what you want:

Thank you David for your help.
So i have to store two copy of my data one for the rendering thread and one
for background(worker) thread, right?

what if I have a polydata with something like 300 000 cells ? could be a
big problem ?

Thanks Again
Antonio Fortino

You should be able to get away with using a ShallowCopy, which will share
the underlying data arrays between the source and target datasets -- that
will help keep memory usage feasible.

But yes, while it's computing the results you'll need to store the final
polydata twice in memory, once for the rendering thread and once for the
background thread. Once the background update completes, you can
shallowcopy the background dataset into the rendering dataset and then
you'll only have a single copy in memory.

Dear all
Dose any body know how to use vtkImageReslice to get oblique slice with
arbitrarily position and direction? I need to set the position and direction
for reslice, and get the slice data, any good idea?

Tao Wang
Thanks all

Hi,

I just spent a few days figuring out how to do just that :)

In my case, the input is a three-dimensional floats blob (a 3D volume) and the output is a two-dimensional floats blob (a 2D slice that I later draw).

1- map your input data to VTK: I'm using an instance of vtkImageImport, but there are many alternatives depending on your input data
2- set up a vtkImageReslice
3- Update() the vtkImageReslice and get the output vtkImageData through GetOutput()

The tricky part is setting up the vtkImageReslice:

2a- connect the vtkImageImport output to the vtkImageReslice input
2b- set up the output (scalar type, dimensionality, extent, origin, interpolation mode)
2c- define the reslice axes and origin

Your question was mainly on how to define the position and direction of the reslice, so more details on 2c: I ended up setting these on my reslices is by using the vtkImageReslice SetResliceAxes method, basically through an array of 16 values: { xdir.x, ydir.x, zdir.x, origin.x, xdir.y, ydir.y, zdir.y, origin.y, xdir.z, ydir.z, zdir.z, origin.z, 0, 0, 0, 1 }

My Obj-C++ code could be useful: https://github.com/spalte/Natural-Image-Building-Blocks/blob/master/NIBuildingBlocks/NIVTKObliqueSliceOperation.mm

Best,

Alessandro Volz

Hi,

Please reply-all to keep the conversation on the mailing list so that
others may benefit and contribute.

I'm not sure what is happening with the texture in the output of the
vtkCleanPolyData. Perhaps there are some points in your data that need
to remain duplicated so that different texture coordinates can be
assigned to each point to avoid undesired texture interpolation. If
that's the case, merging coincident points will necessarily pick just
one of those texture coordinates and throw away the others, making the
texturing look funny. Unfortunately, there is no way to tell
vtkCleanPolyData to not merge where a scalar value is different, but
that appears to be what you need.

If you are going to do this operation only once for the data in the
images you sent me (not attached), I would recommend skipping the
connectivity filter approach to discard the small bits near the
person's shoulders and instead use vtkClipPolyData with, say, a
vtkSphere to define the clip function around the head. This can be
done without writing code using ParaView if you prefer.

HTH,
Cory

Thinks for your good advice! Now I can set the correct transform for my
desired plane. But there comes another problem, the resliced image is not
well centered and aligned, is there some good ways to deal with these?

When that happened to me, I fixed it with reslice->SetOutputOrigin(0, 0, 0). Without that, VTK somehow cropped the output.

If you've already set the output origin to 0,0,0, then you have to compute a better origin to pass in the ResliceAxes. In my code, to determine the origin I apply my outputSliceToInputVoxelTransform to a 0,0,0 vector, and it just works.

They changed the signature on a couple functions in a recent SDK update. I have the changes at home and I'll push a topic soon to update it. If you look at the OpenVR SDK header files you can see the new signature change, it is a pretty easy fix. I'll try to remember to email the diffs tonight when I get home.

I am trying to compile my VTK 7.1 against OpenVR following the documentation: https://blog.kitware.com/using-virtual-reality-devices-with-vtk/

I got all modules  <https://wiki.libsdl.org/Installation> SDL2/  <https://developer3.oculus.com/downloads/> Oculus Windows SDK/  <https://github.com/ValveSoftware/openvr> OpenVR SDK and master branch of VTK from the  <https://github.com/Kitware/VTK> VTK respository . I had used CMAKE 3.0 as usual to compile everything against Visual Studio 2013, as well my VTK 7.0, VTK 6.3.

 

The point is, every time I am trying do build the libraries by compiling my VTK.sln within Visual Studio I got the following errors:

 

Error     871        error C2039: 'API_OpenGL' : is not a member of 'vr'              C:\VTK\VTK-7.1.0VR\Rendering\OpenVR\vtkOpenVRCamera.cxx 108              1            vtkRenderingOpenVR

Error     883        error C2660: 'vr::IVRSystem::ComputeDistortion' : function does not take 3 arguments         C:\VTK\VTK-7.1.0VR\Rendering\OpenVR\vtkOpenVRRenderWindow.cxx        709        1              vtkRenderingOpenVR

 

Error     886        error C2660: 'vr::IVRSystem::GetControllerState' : function does not take 2 arguments         C:\VTK\VTK-7.1.0VR\Rendering\OpenVR\vtkOpenVRRenderWindowInteractor.cxx    126              1            vtkRenderingOpenVR 

 

Somebody knows what it means? I mean somebody have been struggling with the same situation?

 

Thank you for any help.

They changed the signature on a couple functions in a recent SDK update. I have the changes at home and I'll push a topic soon to update it. If you look at the OpenVR SDK header files you can see the new signature change, it is a pretty easy fix. I'll try to remember to email the diffs tonight when I get home.

OK I downloaded openvr 1.0.5 and made a couple more fixes. Just tested it and it all builds and runs.  I merged it into master so you should be able to download an updated master and compile.

 

Thanks

Ken

I'm not getting that error. With the diffs I posted it is compiling OK. What SDK version are you using?

Hi Ken,

 

I got some things regarding 'API_OpenGL' to TextureType_OpenGL within OpenVR SDK. However, there are other issues related to vtkOpenVRCamera, vtkOpenVRRenderWindow, vtkOpenVRRenderWindowInteractor

 

I am looking forward to hearing from you soon.

They changed the signature on a couple functions in a recent SDK update. I have the changes at home and I'll push a topic soon to update it. If you look at the OpenVR SDK header files you can see the new signature change, it is a pretty easy fix. I'll try to remember to email the diffs tonight when I get home.

Hello vtkusers,

I got all modules  <https://wiki.libsdl.org/Installation> SDL2/  <https://developer3.oculus.com/downloads/> Oculus Windows SDK/  <https://github.com/ValveSoftware/openvr> OpenVR SDK and master branch of VTK from the  <https://github.com/Kitware/VTK> VTK respository . I had used CMAKE 3.0 as usual to compile everything against Visual Studio 2013, as well my VTK 7.0, VTK 6.3.

 

The point is, every time I am trying do build the libraries by compiling my VTK.sln within Visual Studio I got the following errors:

Somebody knows what it means? I mean somebody have been struggling with the same situation?

 

Thank you for any help.

Hi Ken, David

 

Thanks, once again.

 

Do you guys have any suggestions regarding Oculus SDK version. Because, I am compiling vtkRenderingOculus against Oculus SDK for Windows V1.10.1 and I have similar issues as well as vtkOpenVR?.

OK I downloaded openvr 1.0.5 and made a couple more fixes. Just tested it and it all builds and runs.  I merged it into master so you should be able to download an updated master and compile.

 

Thanks

Ken

I'm not getting that error. With the diffs I posted it is compiling OK. What SDK version are you using?

Hi Ken,

 

I got some things regarding 'API_OpenGL' to TextureType_OpenGL within OpenVR SDK. However, there are other issues related to vtkOpenVRCamera, vtkOpenVRRenderWindow, vtkOpenVRRenderWindowInteractor

 

I am looking forward to hearing from you soon.

They changed the signature on a couple functions in a recent SDK update. I have the changes at home and I'll push a topic soon to update it. If you look at the OpenVR SDK header files you can see the new signature change, it is a pretty easy fix. I'll try to remember to email the diffs tonight when I get home.

Hello vtkusers,

 

I am trying to compile my VTK 7.1 against OpenVR following the documentation: https://blog.kitware.com/using-virtual-reality-devices-with-vtk/

I got all modules  <https://wiki.libsdl.org/Installation> SDL2/  <https://developer3.oculus.com/downloads/> Oculus Windows SDK/  <https://github.com/ValveSoftware/openvr> OpenVR SDK and master branch of VTK from the  <https://github.com/Kitware/VTK> VTK respository . I had used CMAKE 3.0 as usual to compile everything against Visual Studio 2013, as well my VTK 7.0, VTK 6.3.

 

The point is, every time I am trying do build the libraries by compiling my VTK.sln within Visual Studio I got the following errors:

 

Error     871        error C2039: 'API_OpenGL' : is not a member of 'vr'              C:\VTK\VTK-7.1.0VR\Rendering\OpenVR\vtkOpenVRCamera.cxx 108              1            vtkRenderingOpenVR

Somebody knows what it means? I mean somebody have been struggling with the same situation?

 

Thank you for any help.

Sorry I haven't looked at Oculus in a bit. I heard rumors Oculus works with
OpenVR now but I have not tested it.

Subject: [vtkusers] Issue when loading stl
Message-ID: <b80a9cec-16b3-db14-91cb-384ba3f6742d@rwth-aachen.de>

Hi,

I am currently experiencing issues with loading and displaying stl 
geometries in a software I created using VTK and Python. Searches have 
shown that sporadically other people have seen the same issue and it 
reappears again every year or so.

When loading an stl file I get this message:
ERROR: In ~/SOFTWARE/ParaView-v5.2.0/VTK/IO/Geometry/vtkSTLReader.cxx, 
line 461
vtkSTLReader (0x990c440): STLReader: error while reading file 
blablablainput_files/geometry/rotating_geometries/laufrad_mrf.stl at 
line 3: unable to read point.

So far so fine. But I wondered how it comes. My software worked well on 
Fedora using Python and VTK 6.3. Now I went back to OpenSuse Leap 42.2 
and I get the message from above. So I tried fixing it by installing VTK 
6.3 (in OS 42.2 7.0 is standard). This did not help. I manually 
downloaded VTK 6.3 and later the newest version with git and compiled 
it. Again I get the same message. So I thought Paraview 5.2 works well 
and probably contains VTK. I downloaded and complied it manually. This 
Paraview version opens the stl files without complaining. So I used that 
VTK and modified my system paths to work with that Python wrapper. I get 
the same error message and nothing gets displayed. I changed the error 
message in the source code of the vtkSTLreader in the VTK files that 
came with Paraview and recompiled everything. When now using my software 
with the Python VTK version I get my new modified error message which 
shows my that I am indeed using that vtkSTLReader. In Paraview it still 
opens the stl file without any problems.

Does anyone have an idea what I could do now?

Thanks,
Andr?

hi, 
I compiled vtk 5.6 using cmake and I created solution with 32 bit.
Now, I compiled 64 bit but I didn't use .Net wrapper files. I took error 

"The specified module could not be found. (Exception from HRESULT:

I could not find an dependency. If you need test solution I can send.

Message-ID: <82BBD66598FEF44092F7EF6854A733F621903E38@WP-MBX1B.milky-way.battelle.org>

Hello All-

I'm a relatively new user to the VTK toolkit.  I am currently rendering medical CT data which has a color transfer function applied for the whole scan.  Suspect masses in the scan have bounding boxes (vtkBoxWidget) defined around them.  I would like to be able to toggle a change in their colorization (to and from red) in order to highlight possible cancerous masses.  Is it possible to change the color transfer function only in a subvolume such that a predefined CT number range has its color changed to red?  I would just change the color transfer function for the defined CT number range over the whole scan, but I want to only highlight objects in the predefined suspect areas.

Cheers,
John Tatarowicz

Hi guys,

vcpkg

looks
like a good effort for easing library installation for usage in Visual
Studio. Should we join the effort by adding ITK and VTK? Has anyone
tried/started doing this?

CPack would likely need to support it first. Moving VTK over to the new
superbuild would also help there.

Hi John,

I don?t think its possible to directly apply the color transfer function to
a sub-volume.

You can use the label map mask to achieve the desired results. An example
is provided as a test for composite mask blend
<https://gitlab.kitware.com/vtk/vtk/blob/a1e7fab2ae19f86e9b1f8b97ca53329227f53161/Rendering/Volume/Testing/Cxx/TestGPURayCastCompositeMaskBlend.cxx>.
You would have to create the mask volume based on the sub-volume of
interest and set the mask color function and mask blend factor accordingly.

Alternatively, you could use multi-component support of the volume mapper.
You can create a new vtkImageData from your slices with two components. The
first component would be your whole volume with voxels in the sub-volume
set to a value that would be transparent in the opacity transfer function.
The second component would consist of non-transparent values on voxels in
the sub-volume region. Finally, setting two different color transfer
functions (one for each component) would do the trick. Make sure to set the
components as independent in the volume property.

Hope that helps.

If there is no undergoing effort to "port" VTK to vcpkg, we could go ahead
and add ITK with VTKGlue disabled. Once VTK is added, we could turn on
VTKGlue and make VTK a dependency.

P.S. I originally cross-posted this to ITK and VTK developers lists, but
since I am only subscribed to VTK-users my message was bounced from
VTK-developers. Hence this "merge" message including Francois' response.

to me, vtk-developers, ITK
Never heard of it before. It does look interesting. We could try to
estimate how much work it would be to port ITK (and VTK?)  to that
platform. Since it supports CMake [1], it may not be much work.

Hello,

I am trying to volumerender a scalar 3D point dataset. Since the dataset
is really big I would like to downsample the Dataset into Voxels. Is it
possible to define an ImageDatastructure, where the scalar of each voxel
is an average of the scalars of the points inside the voxel? Is there a
filter for this?

Message-ID: <CAB651cnkOC71LxtgzxyABNcmLZY0WGzdCOuVo-_-De6PnGLkXA@mail.gmail.com>

I am submitting a new class for vtkInteractionStyle, it's a modified
version of "InteractorStyleDrawPolygon"  essentially it draws a
straightline polygon from node to node, each placed by left clicks.

My goal is to eventually add the ability to extract/select points(from a
point cloud) by polygonal selection, and then get that to work with point
cloud library.  Since I'm new to vtk and really this is the first time I've
submitted anything to an open source project I thought this would be a good
starting point for me to submit something and make sure I'm doing things
the right way.

There is a Test project in the zip file where this has been implemented,
should I run other tests or is this typically what you guys are looking
for?

Let me know if I can provide any more information.

Thanks,

Thanks Jon,

The best way to contribute code to VTK is via gitlab. Git can be a little
annoying the first time through but gitlab and buildbot simplify the review
and test efforts that all new code goes through before merging
substantially.

The steps are outlined here:

https://gitlab.kitware.com/vtk/vtk/blob/master/Documentation/dev/git/develop.md
Overall you signup on gitlab.kitware.com, clone VTK to your local machine,
run the SetupForDevelopment script, do your work locally and when satisfied
push the branch to your gitlab.kitware.com account. Finally issue a merge
request and let one of the trusted developers know about it via @username
in a comment. Trusted developers can then trivially run regression tests on
all platforms and suggest changes to make.

Looking forward to the eventual better integration with PCL!

I made a simple portfile [1] for VTK to vcpkg and it seems that it works. At least I was able to build and run the sphere VTK example.

Only problem that I see is that VTK has large number of build configuration options and I don?t know how this could be handled with vcpkg (for example optional QT support).

If there is no undergoing effort to "port" VTK to vcpkg, we could go ahead and add ITK with VTKGlue disabled. Once VTK is added, we could turn on VTKGlue and make VTK a dependency.

Never heard of it before. It does look interesting. We could try to estimate how much work it would be to port ITK (and VTK?)  to that platform. Since it supports CMake [1], it may not be much work.

CPack would likely need to support it first. Moving VTK over to the new
superbuild would also help there.

I have always built VTK with Qt support, and ITK with VTK-glue. Perhaps we
could make those libraries dependencies: ITK depends on VTK, and VTK
depends on Qt?

R?bert, do you intend to make a PR for your additions to vcpkg?

D?enan

Since Qt is available through this system, I agree with Dzenan: It makes
sense to make these depend on each other.

Subject: [vtkusers] Get WindowLevel and WindowWidth from DICOM
Message-ID: <1484106934626-5741754.post@n5.nabble.com>

Hi all.
I was trying to get WindowLevel(WL) and WindowWidth(WW) from DICOM file but
I couldn't find any way.

<http://vtk.1045678.n5.nabble.com/file/n5741754/Capture.png> 
I opened this file in Sante DICOM Viewer and it shows WW: 40 and WL: 200

I tried using vtkImageMapToWindowLevelColors to get windowLevel and
windowWidth but the width and the level are different from the image shown
above for the same file.
the result I get is WW = 255 and WL = 127.5
Is there anyway I can get the windowlevel(WL) and windowwidth(WW)? 
Please help.
Thank you.

Today I will try to modify the portfile to add qt5 dependency and build vtk with qt support and then after testing I will make a pull request.

CPack would likely need to support it first. Moving VTK over to the new
superbuild would also help there.

Subject: [vtkusers] Get normal vector of the closest polydata cell to a

Message-ID: <AM3PR03MB1123FDBD55F9670FD7688546A6660@AM3PR03MB1123.eurprd03.prod.outlook.com>

Hello,

i have a test point p[x,y,z] and a polydata.
I use vtkCellLocator to get the closest cell of the polydata to this point.

I get:
- the closest point
- the squared distance to the closest point
- cell ID

Now I want to get the normal vector of the cell. I know the cell ID but I don't know how to get the
normal vector from it.

Thank you!

Thank you very much!

The problem is that most of the points are on the surface. Therefore test point = closest point.
I only use the cellLocator to get the corresponding cell.

Now I try to get the normale vector of the whole cell (orientation of the cell).

Is there a way to get that vector?

Betreff: Re: [vtkusers] Get normal vector of the closest polydata cell to a given test point

Hi Jordan,

You can use vector between your test point and closest point as NORMAL vector.
Please see code snippet below.
normalizedX is output

double* pos = picker->GetPickPosition();

        double testPoint[3] = {pos[0],pos[1],pos[2]};

        //Find the closest points to TestPoint
        double closestPoint[3];//the coordinates of the closest point will be returned here
        double closestPointDist2; //the squared distance to the closest point will be returned here
        vtkIdType cellId; //the cell id of the cell containing the closest point will be returned here
        int subId; //this is rarely used (in triangle strips only, I believe)
        cellLocator->FindClosestPoint(testPoint, closestPoint, cellId, subId, closestPointDist2);

        std::cout << "Coordinates of closest point: " << closestPoint[0] << " " << closestPoint[1] << " " << closestPoint[2] << std::endl;
        std::cout << "Squared distance to closest point: " << closestPointDist2 << std::endl;
        std::cout << "CellId: " << cellId << std::endl;

        endPoint[0]=pos[0];
        endPoint[1]=pos[1];
        endPoint[2]=pos[2];
        startPoint[0]=closestPoint[0];
        startPoint[1]=closestPoint[1];
        startPoint[2]=closestPoint[2];

// Compute a basis
         double normalizedX[3];
         double normalizedY[3];
         double normalizedZ[3];

         // The X axis is a vector from start to end
         vtkMath::Subtract(endPoint, startPoint, normalizedX);
         double length = vtkMath::Norm(normalizedX);
         length=1;
         vtkMath::Normalize(normalizedX);

For those who are struggling with this I found a solution.
first vtkDICOMImageReader doesn't support getting DICOM image properties for
now(tested in vtk v7). 
To read DICOM image properties you need to download GDCM  can be downloaded
from here <https://sourceforge.net/projects/gdcm/>  

after download and extracting GDCM you need to open CMake
in CMake Check those attributes 
1-GDCM_USE_VTK and select VTK_DIR and vtk directory
2-GDCM_BUILD_SHARED_LIBS 
3-GDCM_BUILD_APPLICATIONS
now click configure and generate. Use your compiler to build it.

In my case I got error while building GDCM that it could not find vtk lib
files. which I already had in the folder. So I had to edit
gdcm-2.6.6/build/cmake_install.cmake file under INSTALL DESTINATION I had to
add lib in front of vtkCommonCore-7.0.dll and the rest of the files, since
in my vtk bin folder all my files had lib prefix.

once GDCM is ready now you need to configure vtk
open vtk in CMake and set and check those attributes
1-GDCM_DIR select the build directory of GDCM
2-USE_GDCM 
now configure and generate.
now you are ready to build vtk.

next thing you need to do is set environment variable for gdcm and import
lib to your project.
now you are ready to use GDCM

To get DICOM image properties you need to do the following

vtkSmartPointer<vtkGDCMImageReader> reader =
vtkSmartPointer<vtkGDCMImageReader>::New();
reader->SetFileName(filename.c_str());
reader->Update();
reader->GetMedicalImageProperties()->GetPatientName(); // to get Patient
Name as an example

double w,l;
reader->GetMedicalImageProperties()->GetNthWindowLevelPreset(0, &w, &l); //
get window width and window level.

Hope this helps.

for any question you can send me an email at tehsunnliu at yahoo.com

Hello David.I'm like wow. I didn't know that there was vtkDICOMReader too. I spent so many days figuring out lol. And I installed vtkDICOM before then I removed it while installing GDCM.
Thank you so much for informing me about vtkDICOMReader. I'll update my post so other people will know.

Hi Alex,

You can also try the vtkDICOMReader that comes with vtk-dicom. It provides
easy access to all of the meta-data, rather than just the limited amount of
information in the MedicalImageProperties object.

Hi guys,

I use vtkDelaunay3D to get the alpha hull of a .vtk polydata file.
The polydata itself looks great (rich in detail) but the ouput of vtkDelaunay3D (alpha hull) looks too course (too big triangles).


vtkSmartPointer<vtkDelaunay3D> delaunay3DAlpha =
vtkSmartPointer<vtkDelaunay3D>::New();
delaunay3DAlpha->SetInputConnection(reader->GetOutputPort());
delaunay3DAlpha->SetAlpha(10);
delaunay3DAlpha->Update();

How can I improve the output?

I actually fixed the problem.
I just moved those lines inside main function.
VTK_MODULE_INIT(vtkInteractionStyle)
VTK_MODULE_INIT(vtkRenderingOpenGL2)
No more error.

Hi Andrew,

Does calling Modified() on the reader cause an update? If not, how about calling SetFileName(NULL) and then SetFileName(previousFileName)? Note that the latter will (should, anyway) invalidate the reader's cache, so it is not without a cost.

ParaView has had this feature requested (for information to get updated when the file gets changed) before and I don't recall whether something was done to address it or not.

You should be able to reload a file through Edit->Reload Files option. Note

I am doing the following and nothing changes the behavior:

reader.SetFileName(None)
reader.GetExecutive().GetOutputInformation(0).Remove(vtk.vtkStreamingDemandDrivenPipeline.TIME_STEPS())
reader.ResetSettings()
reader.ResetCache()
reader.Modified()

Hi Jordan,
Play with the value of Alpha

delaunay3DAlpha->SetAlpha(10);   ----> replace 10 with any other numbers
(smaller and larger) and you will see differences.

Thanks,

Subject: [vtkusers] Arbitrary connectivity table to triangle-only
	connectivity table?
Message-ID: <1484332991633-5741786.post@n5.nabble.com>

Dear all,

I am dealing with the connectivity table of a polygon that is a mix of
triangular/quadrangular/else facets.
That is, the connectivity looks like this: 

0 : 0 1 2 3 4 
1 : 0 1 2 3 4 5 6 
2 : 0 2 3 4 5 6 7 
3 : 4 5 6 7 8 
4 : 2 3 4 6 7 8 
5 : 1 2 3 4 5 6 7 8 

My point is that there should be only three indices after the ":" symbol.

Is there a filter in VTK I could provide this connectivity table with, and
that would return a triangular-facet only connectivity table (obviously with
more rows/facets, but with those facets comprised of exactly three vertices
instead)?

Best, 
Ben

I am still experiencing problems, the Modified() call works only if I don't
change any settings. For example, inserting a call to SetSqueezePoints
causes the wrong number of steps to be reported. Thanks for the help on
this.

Hello everyone,

     I posted few weeks back about a niggling issue I have been facing for a while involving clipping two meshes together using vtkBooleanOperationPolyDataFilter, please see below my previous post. I have been able to write a little application that reproduces this crash easily so that others can review the code and see what needs to be fixed. 
See issue #16954

On tracing the cause of the crash, I noticed that the polydata?s cell data array is null and there seems to be no guard against trying to probe its value, secondly prior to calling SortPolyData, two vtkPolyData?s pd0 & pd1 of which the latter possess no poly and both have their cells and links generated but the latter still lacks poly. I decided to introduce a condition just before building the cells and links for both pd0 and pd1 to check if either have no poly and if so exit the function (return 0), doing so completely prevents my program from crashing. I am not sure if this is the right approach nor if adding the check is necessary.

Subject: [vtkusers] Multiple issues with IntersectionPolyDataFilter
Message-ID: <CAEwdB7aygVTZM5NA4iO2jw8dvZecQguXU9hux7VwNWmnOFYBZA@mail.gmail.com>

I am trying to create multiple lines on a surface mesh by calculating the
intersection between the target mesh and a second surface/plane.  I am
having lots of issues with the IntersectionPolyDataFilter either not
finding the intersection or causing the program to crash.  If I move the
intersecting surface ever so slightly to one side, it seems to work fine.
Does anyone know what is causing it to crash or not return the
intersection?  In other cases, I am getting a lot of other warnings for "no
cell with correct orientation" and "edge not recovered, polygon fill
suspect" but I don't know if these are related to my previously mentioned
issues.  Here is some code to reproduce the issues.  Btw, I am running
version 7.1 from source (downloaded it about a month ago).  I have not been
able to create a minimum reproducible set of code to recreate the issue of
not finding intersections yet.  Any help is appreciated.

Thanks!
Alex

Bill, 
thanks for pointing out vtkTriangleFilter. However the filter appears to
fail (i.e returns a polydata with 0 polys) when the input polydata has
self-intersecting cell borders like those shown on the attached pictures.
This is due to the inconsistency of the original connectivity table.

<http://vtk.1045678.n5.nabble.com/file/n5741792/Screen_Shot_2017-01-14_at_12.png> 

I have more topological information about the vertices (which edges they
belong to) so I should be able to sort it out.

Subject: [vtkusers] VTK crashes when adding multiple lights
Message-ID: <CAL=MvsrTKZJXoVLAn+NYb_utZxpvTMXry-tsEE98EVemKtasNQ@mail.gmail.com>

Hello Everyone,

I'm working on illuminating a scene and noticed that adding more than 6
lights cause issues; if they are not positional, then spurious colors start
appearing after adding 6 and vtk crashes after adding 19 lights.
It the lamps are positional, then it crashes when adding more than 6.

I'm not sure this is a bug, but the vtk light class does not indicate such
a limitation.

best,
carlos

	Python 3
Message-ID: <CAB8-E4BPww6rC59urnO=05skwGj2wQDVKmHgp4WfB9dXXP8GiQ@mail.gmail.com>

Hello everyone

I want to use VTK without its rendering possibilities in Python 3 on Linux
or Mac OSX.
When I compile VTK, I have a include file error.
This error occurs for VTK7 and VTK7.1 on Linux and Mac OSX.

The error occurs on file
Wrapping/Python/vtkAngularPeriodicDataArrayPython.cxx with error
Common/Core/vtkAngularPeriodicDataArray.txx:17:10: fatal error:
'vtkMatrix3x3.h' file not found

I disable the rendering with these specific options

    -DVTK_Group_Rendering:BOOL=OFF
    -DVTK_Group_StandAlone:BOOL=OFF

The second option is required as discussed
http://public.kitware.com/pipermail/vtkusers/2015-May/090915.html

Below are the commands are that reproduced the bug, and the error

Do I miss something with VTK configuration?

Subject: [vtkusers] Quad Trees
Message-ID: <1484445270235-5741796.post@n5.nabble.com>

Hi
I  have been looking  vtkHyperOctree to implement a quad tree for a wavelet
decomposition of a 2d function. One of the things I would like to do is
assign attributes to all the nodes in the tree. I noticed
one can assign attributes only at the leaf level nodes which does not quite
meet my needs. Was wondering if  am missing something? Any suggestions would
be appreciated.

Regards
ramesh

Ilog is logical matrix of size 728x728x25 whose cross-section looks like

[image: enter image description here] <https://i.stack.imgur.com/Z8qCP.png>

In this image the red color signifies the value 1 and the blue color
signifies the value 0.

but when the above code is compiled the output is always a box like

[image: enter image description here] <https://i.stack.imgur.com/Q6ESB.png>.

The matrix contains values just zeros and ones. Using that logic the value
with zeros have given full transparency and the values with zero have full
opacity.


The question can also be found on: http://stackoverflow.com/

yes, kind of. The problem is, that with a lot of tabs I'm getting:

Maximum number of clients reached
ERROR: In [...]/VTK/Rendering/OpenGL/vtkXOpenGLRenderWindow.cxx, line 530
vtkXOpenGLRenderWindow (0x32b207d0): bad X server connection. DISPLAY=:0. Aborting.

calling chart->SetVisible(false) doesn't help unfortunately. I need to completely destroy the view somehow in hideEvent.

Thanks
Jan

It is currently coded for a maximum of 6. In vtkOpenGLPolyDataMapper.cxx
there are a bunch of [6] associated with the lighting code that could be
made more general and specified at run time.

Hello there!

We're using VTK for medical imaging but there is long standing issue we can't understand so far
When 3D opacity is around 0.8 rotation gives some very strange mirror effect when near part is becoming invisible (very transparent)
There is issue demonstration: https://drive.google.com/file/d/0B-Ae8luypUS0UTdTNjd6a1hoS2M/view

I had opened an issue there: https://gitlab.kitware.com/vtk/vtk/issues/16950

Thank you,
Mikhail

If you want to correctly render transparent objects you need to use
DepthPeeling

For background on why see https://en.wikipedia.org/wiki/Depth_peeling

renderer->UseDepthPeelingOn()


By default VTK uses alpha blending which is faster but suffers from view
dependent artifacts. In the new OpenGL2 backend depth peeling is supported
everywhere so it might be worthwhile for us to turn it on by default with
some low number of default peels for that backend.

Hi Alex,

Yeah, that filter, and the boolean operations filter, fails on some
configurations of input geometry, and it can be difficult to track
down what is going on. That's why they are not more robust. I
apologize for that, but it is a tricky operation to get right.

At the moment, there are not resources to put into making the filter
more robust, but we welcome community contributions to that end.

Thanks,
Cory

Subject: [vtkusers] Wrong volume calculation (vtkMassProperties)
Message-ID: <1484578941308-5741807.post@n5.nabble.com>

Hello,
I want to compute volume of arbitary polyhedron. I made test code, where
polyhedron is created, converted to PolyData, triangulated and, finally,
volume is computed. So, the volume of created polyhedron should be equal to
1.5, but vtkMassProperties output 0.4375. Points are entered right and
Paraview visualise figure right. Please, help me to understand what's wrong
with code? Thanks.

Hi All, 

I did some more digging on the and found a solution that works (at least so far). My custom VTK filter class (derived from vtkImageAlgorithm) contained a method RequestUpdateExtent, which contained the following code:

  for (int i=0; i<numInputPorts; i++)
    {
    int numInputConnections = this->GetNumberOfInputConnections(i);
    for (int j=0; j<numInputConnections; j++)
      {
      vtkInformation* inputInfo = inputVector[i]->GetInformationObject(j);
      inputInfo->Set(vtkStreamingDemandDrivenPipeline::EXACT_EXTENT(), 1);
      }
    }

I changed:
	inputInfo->Set(vtkStreamingDemandDrivenPipeline::EXACT_EXTENT(), 1);

to:
	inputInfo->Set(vtkStreamingDemandDrivenPipeline::WHOLE_EXTENT(),WholeExtent,6);

where the array WholeExtent is the maximum extent computed over all input and output ports. 

This seems to work, but I am not sure why. If anyone could point me in the direction of some explanation of the purpose behind extents in the VTK pipeline and how they are best used I would be very grateful. 

Thanks

Kit

Hi Kit,

The VTK image pipeline updates occur in three passes (RequestInformation(),
RequestUpdateExtent(), RequestData()), which are discussed in the VTK
Users's Guide and also on the following web page: http://www.vtk.org/Wiki/
VTK/Tutorials/New_Pipeline

A filter should never directly set the WHOLE_EXTENT of its input.  It is
only allowed to set the WHOLE_EXTENT of its output.

With respect to the extent, the three passes of the pipeline work like this:

In RequestInformation(), a filter sets the WHOLE_EXTENT of its output.
This is how a filter tells the pipeline "this is how data I can produce".
A filter can be asked to produce less that this (as described in
RequestUpdateExtent, below).  In most cases, what a filter does in
RequestInformation() is check the WHOLE_EXTENT of its input, and then use
that same WHOLE_EXTENT for its output.

In RequestUpdateExtent(), a filter can request that an produce less than
the WHOLE_EXTENT of that input.  It does this by setting the UPDATE_EXTENT
of the input, while tells the pipeline "I need at least this much data from
this input".  Usually, it will set the UPDATE_EXTENT of the input to the
WHOLE_EXTENT of the input.  If a filter also sets EXACT_EXTENT for the
input, that tells the pipeline "I need exactly this much data from this
input".  If you do not set EXACT_EXTENT, then the pipeline will produce at
least as much data as requested by UPDATE_EXTENT, but possibly more.

Finally, in RequestData() a filter should call GetExtent() on each input
data object to see how data is actually there.

I'm going to try again, with fewer typos:

The VTK image pipeline updates occur in three passes (RequestInformation(),
RequestUpdateExtent(), RequestData()), which are discussed in the VTK
Users's Guide and also on the following web page:
http://www.vtk.org/Wiki/VTK/Tutorials/New_Pipeline

only allowed to set the WHOLE_EXTENT of its output.

With respect to the extent, the three passes of the pipeline work like this:

In RequestInformation(), a filter sets the WHOLE_EXTENT of its output.
This is how a filter tells the pipeline "this is how much data I can
produce".  A filter can be asked to produce less than this (as described in
RequestUpdateExtent, below).  The default behavior of RequestInformation()
is to check the WHOLE_EXTENT of the input, and then use that same
WHOLE_EXTENT for the output.

In RequestUpdateExtent(), a filter can request for the pipeline produce
less than the WHOLE_EXTENT of that input.  It does this by setting the
UPDATE_EXTENT of the input, while tells the pipeline "I need at least this
much data from this input".  Usually, it will set the UPDATE_EXTENT of the
input to the WHOLE_EXTENT of the input.  If a filter also sets EXACT_EXTENT
for the input, that tells the pipeline "I need exactly this much data from
this input".  If you do not set EXACT_EXTENT, then the pipeline will
produce at least as much data as requested by UPDATE_EXTENT, but possibly
more.

Finally, in RequestData() a filter should call GetExtent() on each input
data object to see how data is actually there.

Can you load your app in the debugger to see where the crash happens?

the 'maximum number of clients' error might be because you don't close the
X window when you close a tab.
Instead of just setting the view to nullptr try to delete the view as well.

Do you use OpenGL1 or OpenGL2 for VTK?

I am compiling the vtk5.10 release version, because I want to use the vtkMFC.dll. But I encounter this error:
error C2040: 'vtkCritSecType' : 'CRITICAL_SECTION' differs in levels of indirection from 'pthread_mutex_t' .
Could anyone help me to solve this problem? Thanks

hi,
Thanks for your reply!
which version are you using? I am using vtk 5.10 and also test with vtk 6.1.
Below is my revised code:

vtkSmartPointer<vtkDataWriter> writer=
vtkSmartPointer<vtkDataWriter>::New();
writer->SetFileName("delaunay3.vtk");
writer->SetInputData(delaunay->GetOutput());
writer->Write();

error C2664: 'void vtkWriter::SetInputData(vtkDataObject *)' : cannot convert parameter 1 from 'vtkUnstructuredGrid *' to 'vtkDataObject *'

Try to add this after Delaunay3D:


       vtkGeometryFilter* geom = vtkGeometryFilter::New();
        geom->SetInputData(delaunay3DAlpha->GetOutput());
        geom->Update();


writer->SetInputData(geom->GetOutput());


Moreover:

#include <vtkUnstructuredGrid.h>

Hello everyone,

Can anybody tell me how the lighting model is implemented on VTK? I'm
looking for any concrete implementation. I've tracked vtkLights usage, but
I got nothing so far.

I want to play with the lighting models, but first I wanted to know how
they works.

Cheers,

Pato

Subject: [vtkusers] Reading Parallel XML Files Piece by Piece
Message-ID: <f47eca06-02e1-605f-a18e-b56606f9b4e3@ovgu.de>

Hi VTK users,

I am converting my (parallel) program to output (PolyData) files in
parallel VTK XML format. I do this to improve efficiency and because the
data can become too large to be contained in a single process' memory
all at once.

I have been successful in writing the parallel files, but now I also
need to be able to read them back in. Because of the size of the data,
just reading it into one giant data set all at once is not feasible.
What I would need to do is read the data piece by piece, and distribute
it to the parallel processes. The given class vtkXMLPPolyDataReader does
not seem to offer a way of doing that, or I don't understand it from
just reading the documentation and browsing the source code a little. It
offers a GetNumberOfPieces() function, but no public function that
explicitly reads only a single piece. The GetOutput() function has an
overload that takes an index, but the non-overloaded version just calls
GetOutput(0), so it seems implausible that this is the piece index.

What would be the best way to read a parallel VTK XML file piece by
piece? Is there something I'm missing in the reader class? Is there a
simple way of getting the piece file names from the summary file to read
them separately? Please advise.

Best Regards,

Timo

Hi Timo,

The pieces that are read on each process are typically specified through
the pipeline from subsequent filters. Something like a writer that can deal
with pieces will request the number of pieces that can be provided to the
writer and based on that the writer would then specify which pieces it
wants. The reader then produces those pieces. See the example at
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Broken/IO/XMLPUnstructuredGridWriter
for an example.

Cheers,
Andy

You can try using vtkDICOMReader instead. In CMake you will have to add
Module_vtkDICOM

Subject: [vtkusers] vtkPointCloudFilter changes type of data arrays to float
Message-ID: <CAHjnjh6Z7mDLL2=Tc=r981iXcBfJVx=xerxqu8n3dRDERpe3YQ@mail.gmail.com>

Hey,

I was writing a custom point cloud filtering algorithm and came across the
vtkPointCloudFilter class,
which looks like a convenient base for this kind of filter. However, in my
opinion it behaves strangely
when it comes to the handling of data arrays bundled with the points. The
documentation says that
"The filter copies point attributes from input to output consistent with
the filtering operation", and
indeed it does, but while copying it changes the type of the attribute
arrays, everything becomes a
float! Here is a small example that uses vtkRadiusOutlierRemoval (derived
from vtkPointCloudFilter).
I create several points with an unsigned char attribute, and pass it
through the filter.


#include <iostream>

#include <vtkPoints.h>
#include <vtkPolyData.h>
#include <vtkPointData.h>
#include <vtkSmartPointer.h>
#include <vtkUnsignedCharArray.h>
#include <vtkRadiusOutlierRemoval.h>

int main(int argc, const char** argv)
{
  const double pt1[3] = { 0, 0, 0};
  const double pt2[3] = { 1, 0, 0};
  const double pt3[3] = { 2, 0, 0};

  auto points = vtkSmartPointer<vtkPoints>::New();
  points->SetDataTypeToDouble();
  points->InsertNextPoint(pt1);
  points->InsertNextPoint(pt2);
  points->InsertNextPoint(pt3);

  auto labels = vtkSmartPointer<vtkUnsignedCharArray>::New();
  labels->SetName("label");
  labels->SetNumberOfComponents(1);
  labels->InsertNextValue(1);
  labels->InsertNextValue(2);
  labels->InsertNextValue(3);

  auto poly_data = vtkSmartPointer<vtkPolyData>::New();
  poly_data->SetPoints(points);
  poly_data->GetPointData()->AddArray(labels);

  auto outlier_removal = vtkSmartPointer<vtkRadiusOutlierRemoval>::New();
  outlier_removal->SetInputData(poly_data);
  outlier_removal->SetRadius(1.5);
  outlier_removal->SetNumberOfNeighbors(2);
  outlier_removal->Update();

  auto output = outlier_removal->GetOutputDataObject(0);
  auto attributes = output->GetAttributes(0);

  std::cout << "Output attributes: " << attributes->GetArrayName(0) << ",
type: " << attributes->GetArray(0)->GetDataTypeAsString() << std::endl;

  return 0;
}


This example prints

Output attributes: label, type: float


So what happens is that the "label" attribute, that was originally of type
unsigned char, becomes a
float attribute in the output of the filter.

It this behavior a bug or a feature? Or maybe I am missing a flag somewhere
which controls this
behavior?

Cheers,
Sergey

Thanks David,

That clarifies things for me. Just to make sure I have got it, I will flesh out what I am trying to do and the way I understand it should be handled based on your response. Here goes:

My data type, let?s call it myGrid, is inherited from a vtkImageData. And similarly there is a myGridAlgorithm which acts as a base for constructing filters and sources to work on myGrid data.  So an example pipeline might be something like this.

src1 > data1 [M by N myGrid object]
src2 > data2 [P by Q myGrid object] 
filter1 < data1, data2 > data3 [M by N myGrid object]

So in src1 and src2 I should implement a RequestInformation(), which sets the WHOLE_EXTENT on the output ports to M by N and P by Q respectively and the RequestInformation() in filter1 should set the WHOLE_EXTENT of its output port to be the same as input 0.  Is this correct? Note that in the above example we may have P>M or Q>N, would this mess things up?

Thanks for you help on this

Kit

If the size of the output is the same as the size of input 0, then yes it
should copy WHOLE_EXTENT from input0 to the output.

And if you want to keep things simple (i.e. if you don't require your
filter to be able to stream just part of data set), then set the UPDATE_EXTENT
for each input to the WHOLE_EXTENT of that same input.  Then the filter
will update the whole data set every time it executes.

Your image is compressed, and the vtkDICOMImageReader cannot read
compressed images.  If you install GDCM, you can use gdcmconv to decompress
the image.  Then vtkDICOMImageReader will be able to read it.

PointCloudFilter was promoting all integral arrays to float.
I am working on a patch and test.

Subject: [vtkusers] VTK updated to CMake 3.3 and C++11
Message-ID: <CAFzjYVon78XL0EZ=iawcHy_nG7HmgVK8Cr8cUy13LOfMeO8y-g@mail.gmail.com>

I am happy to announce that over the last two weeks we have rolled out a
series of updates to VTK that mean the minimum required CMake version
is now 3.3 (see below), and now builds with C+11 enabled.

Yes VTK now requires a C++11 capable compiler. Initial we are only asking for a
minimal set of C++11 features (nullptr), but as continue forward through the
year we are going require a larger set of C++11 features. The final exact
versions for each compiler have not been set in stone, but a rough estimation
would be:
  - GCC 4.8+
  - Clang 3.3+
  - XCode 5.0+
  - MSVC 2013+

I wanted to send this announcement out to bring up a couple of points:

1. Thanks to everyone that has helped get VTK ready for C++11! The final CMake
switch over to C++11 was very easy, only because of all the hard work that other
developers did in anticipation of this. So thank you very much.

2. The major reason for this slow roll out of C++11 is so that we minimize the
impact on current VTK merge requests, while also minimizing dashboard
instability. Contributors please be aware of these changes if you have long
running branches.

3. We currently have dashboard machines running GCC 4.6 & 4.7. We are currently
working up a plan on how best to transition these machines to at least GCC 4.8
as the roll out continues.

4. The current MinGW dashboard machine doesn't support C++11 and will be
removed, with no plan of a replacement at Kitware. If the community is
interested in maintaining a newer MinGW machine I can provide assistance
on how to setup a machine.


============

Why CMake 3.3:

We have chosen CMake 3.3 as the minimum required version for numerous reasons,
the most important of those reasons being:

- It is the first CMake release that offers C++11 support for all four major
  compilers ( GCC / MSVC / Clang / XCode ).

- The CMake version is sufficiently new enough that it allows for a cleaning
  of the existing CMake infrastructure. The current CMake minimum version
  requires VTK to maintain forks of numerous FindPackages and Modules that are
  part of newer CMake versions.

- Supports HTTPS downloads, with all the official binaries come with support.
  Allowing for migration of external data to a HTTPS only server. Something we
  are going to require in the near future.

I have a computer with a non-c++11 compiler. I would expect a better
error message.

Something like: VTK requires a c++11 compiler.

After update vtk I get these cmake errors
  "Clang"

  version 3.0.0.

  CMake/vtkModuleMacros.cmake:646 (vtk_add_library)

I agree that the current error messages are not sufficient. I will
work on a MR that provides better error reporting.

Subject: [vtkusers] write 2D mesh to ExodusII
Message-ID: <cd4aa123-f8a0-0ab0-3006-c6c7d3e83ade@auckland.ac.nz>

hi,

I am writing a 2D mesh to an ExodusII file using vtkExodusIIWriter (in 
Python).  I'm using VTK 5.8.

The ExodusII file has a 'dimension' property which appears to be set to 
3 by default. I would like to be able to set this to 2 for 2D meshes. 
Otherwise it doesn't read in properly in other applications (e.g. PETSc).

 From reading the C++ documentation for vtkExodusIIWriter it looks like 
there is a SetModelMetadata() method which takes a vtkModelMetadata 
object as argument. This object in turn has a SetCoordinateNames() 
method which takes an integer dimension parameter and an array of 
coordinate names.

However in Python this method doesn't seem to be exposed- I get an 
AttributeError when I try to use it. I also get a segfault when I try to 
use the SetModelMetadata() method (maybe because the vtkModelMetadata 
object isn't set up right).

Not sure if I'm on the right track here, or if there is some other way 
to achieve what I want?

Regards, Adrian

Hi Bill,

Thanks for the prompt reply and the patch. I see that you have
submitted a merge
request <https://gitlab.kitware.com/vtk/vtk/merge_requests/2393> already,
so looking
forward to have this fixed in the next release. In the meanwhile I'll just
copy the patched vtkPointCloudFilter into
my project.

Cheers,
Sergey

J-C,

With all the talk of VTK requiring newer CMake, newer Qt, newer C++, I thought I'd ping you on this.  Is your buildbot updated from OS X 10.6 yet?

Cheers,

Hi,

The C++11 check is failing for me. I'm using CMAKE 3.6.2 on windows with
Visual studio Community 15.

Removing the check within cmake allows me to build without issues.

I'm building from gitlab's main repo, updated today.

best,
carlos

Hi Carlos,

A regression to the build system was merged in last night that broke
building with Visual Studio. A correction was just ( 15 minutes ago )
merged into VTK master that restores building with Visual Studio.

Sorry for the inconvenience.

Message-ID: <20170119215431.968849036@mail.rogue-research.com>

Hi all,

I have a scene with various actors and everything draws and behaves correctly.  If I then simply remove and re-add an actor like so:

	renderer->RemoveViewProp(actor);
	renderer->AddViewProp(actor);

then should I expect things to redraw exactly as they were?  I thought yes, but I have a case where the answer is no.  Here's a screenshot:

<https://www.rogue-research.com/VTKRemoveAddBug.png>

The left is correct and before the remove+add.  The right is after and incorrect.

Is this expected? buggy?

Thanks,

It should be the same unless any of the actors are coincident or
translucent. In that case the order of the actors can make a difference.
alpha blending for transparency is order dependent and with coincident
geometry either first or last wins (I forget which in VTK). Not sure if
that applies in your example.

The green thing in my screenshot is indeed translucent.  Making it fully opaque indeed "fixes" the problem.

I don't think I have anything coincident, though things overlap.

So how do I control the order?  vtkViewport.h has AddViewProp() but I don't see any API to, for example, add it first or last.  And vtkPropCollection's docs say that it's 'unsorted'.

Thanks Ken!

I believe it is unsorted in that it is rendered in the order the props are
added (not sorted by some other metric). Opaque actors get rendered before
translucent, but if you have multiple translucent actors they are rendered
in the order added. I suppose you could

renderer->GetViewProps()->InsertItem(loc, yourActor);

if you know what location you want.

Subject: [vtkusers] Messed up pdf output from vtkGL2PSExporter
Message-ID: <1484881576492-5741884.post@n5.nabble.com>

Dear all, 
I am trying to export a view of a vtkChart to pdf, but the plots I am
getting are messed up (the xticks are overlapping with the xaxis and the
legend box transparency is off, among other things).

I've set up a minimum example based off of the LinePlot tutorial, with a few
lines added for the exporter. Running the program and comparing the pdf
output to the vtk window clearly shows the issue, at least on my laptop. 

Any clues?

Thanks, 
Ben

Subject: [vtkusers] vtk - PointInsideObject - is the problem is due to
	precision?
Message-ID: <CAJk8dSD1LovrtP3EMiSajCJz_nHmDvnivwAEjdScUinC36j5Pw@mail.gmail.com>

Hi All,
I am trying to extend the example to find points inside an object (
http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/PointInsideObject). The
idea is to fill a 3D volume with points inside it.

While doing so, I am finding that for some points which are actually
outside the object are getting detected as inside.
To picture on the left is my original object and on the right is the object
filled with points

[image: Inline image 1]        [image: Inline image 2]

You will find that few points which are actually outside are getting
detected as inside.

Any idea what is happening? The object file and the source codes are
attached.

Thanks,
Chiranjib

Hi, 
I wonder why result from below code are different:
-----------------Code 1: using vtkDICOMImageReader  --------------------------
vtkDICOMImageReader *reader = vtkDICOMImageReader::New();
reader->SetDirectoryName("***");  <----- DICOM folder


        // After get reader, all below are same
vtkSmartPointer<vtkMarchingCubes> boneExtraractor = vtkSmartPointer<vtkMarchingCubes>::New();
boneExtraractor->SetInputConnection(reader->GetOutputPort());
boneExtraractor->GenerateValues(1, 200, 3097);
vtkSmartPointer<vtkPolyDataNormals> boneNormals = vtkSmartPointer<vtkPolyDataNormals>::New();
boneNormals->SetInputConnection(boneExtraractor->GetOutputPort());
boneNormals->SetFeatureAngle(60.0);
vtkSmartPointer<vtkStripper> boneStripper = vtkSmartPointer<vtkStripper>::New();
boneStripper->SetInputConnection(boneNormals->GetOutputPort());
vtkSmartPointer<vtkPolyDataMapper> boneMapper = vtkSmartPointer<vtkPolyDataMapper>::New();
boneMapper->SetInputConnection(boneNormals->GetOutputPort());
boneMapper->ScalarVisibilityOff();
vtkSmartPointer<vtkActor> bone = vtkSmartPointer<vtkActor>::New();
bone->SetMapper(boneMapper);
vtkRenderer *aRenderer = vtkRenderer::New();
vtkRenderWindow *renWin = vtkRenderWindow::New();
renWin->AddRenderer(aRenderer);
vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
iren->SetRenderWindow(renWin);
aRenderer->AddActor(bone);
renWin->Render();
iren->Initialize();
iren->Start();


Result: please see attache screenshot: vtkDICOMImageReader.png


-----------------Code 2: using vtkDICOMReader--------------------------
        vtkSmartPointer<vtkStringArray> filenames = ****;        //<----- Fill DICOM files
vtkSmartPointer <vtkDICOMFileSorter> sorter = vtkSmartPointer <vtkDICOMFileSorter>::New();

renWin->Render();
iren->Initialize();
iren->Start();


Result: please see attache screenshot: vtkDICOMReader.png
===============================
the result from vtkDICOMImageReader is what I expected. and the result from vtkDICOMImageReader  seems only skin is visuable, and bone is invisable.
any body can tell me why?  how should I update the code of vtkDICOMReader to visualize the bone structure?


Thanks 
James

Hi Chiranjib,

Have you tried reducing the spatial tolerance with the method 
SetTolerance() of vtkSelectEnclosedPoints() ?

I have experienced a similar situation, and setting an appropriate 
tolerance (e.g. a small fraction of the size of the object) solved the 
problem.

Cheers,

Andrea

Subject: [vtkusers] Large dataset to plot with VTK
Message-ID: <CA+UkBtyu4fR-Ksg1WVT6bHAZmcy7UDNf+4mOmKN=9BuY9FpCyw@mail.gmail.com>

Hello folks!

I'm trying to plot some 3D and 2D graphics with vtk, but I have to use a
large dataset with few million points. What is the best way to plot this
amount of data which will spent less time and memory?

Thanks in advance!

Best regards,

Subject: [vtkusers] [vtkUsers] Mapping the real x, y,
 z points to the volume indices i, j, k using vtkImageData
Message-ID: <ddb48068-ff27-0deb-d823-8a76bbc669ce@irisa.fr>

Hi vtkUsers,

I have a hard time with ComputeStructuredCoordinates.

* Goal:
  I have a vtk file and a nii file. I want to recover some scalar values 
from the volume to assign it to the surface scalar. So, essentially, I 
want to find the mapping from the real x,y,z points to the volume 
indices i,j,k.


* Observations:
1) When displaying the surface and the volume in the real frame they fit 
perferctly, so data looks not to be the problem.
2) When making the (x,y,z)_Real to (i,j,k)_Volume correspondances using  
ComputeStructuredCoordinates or FindPoint, I do not have the expected 
results.
In particular, the coordinates given by ComputeStructuredCoordinates 
indicates that the points are outside the volume or have wrong scalar 
values. In other words, it does not seem to do the job I expect.

* Code:

```

// img is a vtkSmartPointer<vtkImageData> loaded from 
vtkSmartPointer<vtkNIFTIImageReader>
// surf is a vtkSmartPointer<vtkPolyData> loaded from 
vtkSmartPointer<vtkPolyDataReader>

for(int i=0;i<surf->GetNumberOfPoints();++i)
{
     std::cout<<i<<","<<std::flush;
     double *v=surf->GetPoint(i);

     int ijk[] = { -1,-1,-1};
     double *foopcoords;
     int isOk=img->ComputeStructuredCoordinates(v,ijk,foopcoords) ;

      if(isOk && (ijk[0]>0 && ijk[1]>0 && ijk[2]>0))
         {float v=img->GetScalarComponentAsFloat(ijk[0],ijk[1],ijk[2],0);
          scal->InsertValue(i,v);
         }
     else
         {scal->InsertValue(i,-1);}
}
```

I also try to use FindPoint instead:
```
   int id = img->FindPoint(v);
   if(id>-1)
       {
scal->InsertValue(i,img->GetPointData()->GetScalars()->GetTuple(id)[0]);
     }
       else
       {scal->InsertValue(i,-1);}

```
  but have the same issue.

* Question

I don't understand how to fix this. Am I wrongly understand the purpose 
of ComputeStructuredCoordinates ? Are there any voxels to real frames 
that are not accounted for when using this function (or extra used ones) ?

HI Andrea,
Thanks for the quick and effective reply. By default the tolerance is set
to =.001 and I tried with different values and by using the tolerance value
= 0.0001, I get a much cleaner data that I am looking for. IT looks like
this now

Thanks much for your help :)

Thanks and regards,
Chiranjib

Hi James,

When applying thresholds to CT data, use the RescaleIntercept and
RescaleSlope so that the thresholding is based on the real data values (in
Hounsfield units).

Also see the "CT and PET rescaled values" section of the following page:
http://dgobbi.github.io/vtk-dicom/doc/api/image_reader.html

Cheers,

Can you provide an example of the rendering and pdf? Also, which VTK
backend are you using, OpenGL or OpenGL2?

I ran the test on the OpenGL2 backend and noticed the artifacts. The
PDF backend for GL2PS is somewhat lackluster -- things like text
alignment tend to come out badly.

The postscript backend, however, is much more robust, and changing the
output from PDF to PS produces a much better rendering. You may have
better luck exporting to postscript and converting afterwards.

HTH,
Dave

David, 
thanks. The PS output looks much better from the alignment standpoint, but
it is unfortunately cropped in a portrait-like format.

Are you getting something similar? All I did was to replace   exporter ->
SetFileFormatToPDF(); by   exporter -> SetFileFormatToPS();


Attached is a screenshot of the PS output

That sounds like an issue with the postscript viewer application. If I
open the .ps file with ghostscript, I see the portrait cropping. But
if I open it with okular (the KDE PDF viewer) or convert it to PDF
using imagemagick, it looks correct. See the attached PDF file
produced by imagemagick from the postscript.

Is it possible to import an OBJ file with shared vertices? If so, how would I go about doing that most efficiently? I need to obtain a resulting mesh with indexed vertices for the triangles. Thanks!

Subject: [vtkusers] 3D vessel surface reconstruction
Message-ID: <CAFjn-L2CRU0sty8SdVc7Eo=0k_BEEJMGz+x4VndDZk_XNnkO+w@mail.gmail.com>

Hi,

I have a 3D vascular free-hand ultrasound volume containing one vessel, and
I am trying to reconstruct the surface of the vessel. The 3D volume is
constructed from a stack of 2D images/B-scans, and the contour of the
vessel in each B-scan has been segmented; that is, I have an ellipse
representing the contour of the vessel in each B-scan in the volume. I have
tried to reconstruct the contour of the vessel by following the VTK example
of 'GenerateModelsFromLabels.cxx' (
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Medical/GenerateModelsFromLabels).
However, the result is not a smooth surface from one frame to another as I
would have hoped for it to be. It is discontinuous and irregular, and the
surface doesn't connect the vessel contours between two adjacent frames in
the volume if the displacement between the ellipses is large. In my
approach, I basically used DiscreteMarchingCubes ->
WindowedSincPolyDataFilter -> GeometryFilter.

I played around with the passband, smoothingIterations and featureAngle
parameters, and I was able to obtain the best following result:

https://snag.gy/yqK3Fd.jpg
https://snag.gy/txu6Ur.jpg
https://snag.gy/ksJfUa.jpg


As you can see, it is not a smooth continuous surface with a lot of
uninterpolated "holes" between adjacent frames, but it is all right. Can it
be made better? I also tried using a 3D Delaunay triangulation, but it only
gave me the convex hull, which is not the output I expected. I would like
to know if there is a better approach towards reconstructing a surface that
closely follows the contour of the vessel from one B-scan to the next in a
volume?

A minimal working example is shown below:

vtkSmartPointer<vtkImageData> vesselVolume =
vtkSmartPointer<vtkImageData>::New();

int totalImages = 210;

for (int z = 0; z < totalImages; z++)
{
std::string strFile = "E:/datasets/vasc/rendering/contour/" +
std::to_string(z + 1) + ".png";

cv::Mat im = cv::imread(strFile, CV_LOAD_IMAGE_GRAYSCALE);

if (z == 0)
{
vesselVolume->SetExtent(0, im.cols, 0, im.rows, 0, totalImages - 1);
vesselVolume->SetSpacing(1, 1, 1);
vesselVolume->SetOrigin(0, 0, 0);
vesselVolume->AllocateScalars(VTK_UNSIGNED_CHAR, 0);
}

std::vector<cv::Point2i> locations;   // output, locations of non-zero
pixels
cv::findNonZero(im, locations);

for (int nzi = 0; nzi < locations.size(); nzi++)
{
unsigned char* pixel = static_cast<unsigned
char*>(vesselVolume->GetScalarPointer(locations[nzi].x, locations[nzi].y,
z));
pixel[0] = 255;
}
}

vtkSmartPointer<vtkDiscreteMarchingCubes> discreteCubes =
vtkSmartPointer<vtkDiscreteMarchingCubes>::New();

discreteCubes->SetInputData(vesselVolume);
discreteCubes->GenerateValues(1, 255, 255);
discreteCubes->ComputeNormalsOn();

vtkSmartPointer<vtkWindowedSincPolyDataFilter> smoother =
vtkSmartPointer<vtkWindowedSincPolyDataFilter>::New();

unsigned int smoothingIterations = 10;
double passBand = 2;
double featureAngle = 360.0;

smoother->SetInputConnection(discreteCubes->GetOutputPort());
smoother->SetNumberOfIterations(smoothingIterations);
smoother->BoundarySmoothingOff();
//smoother->FeatureEdgeSmoothingOff();
smoother->FeatureEdgeSmoothingOn();
smoother->SetFeatureAngle(featureAngle);
smoother->SetPassBand(passBand);
smoother->NonManifoldSmoothingOn();
smoother->BoundarySmoothingOn();
smoother->NormalizeCoordinatesOn();
smoother->Update();

vtkSmartPointer<vtkThreshold> selector =
vtkSmartPointer<vtkThreshold>::New();

selector->SetInputConnection(smoother->GetOutputPort());
selector->SetInputArrayToProcess(0, 0, 0,
vtkDataObject::FIELD_ASSOCIATION_CELLS,
vtkDataSetAttributes::SCALARS);

vtkSmartPointer<vtkMaskFields> scalarsOff =
vtkSmartPointer<vtkMaskFields>::New();

// Strip the scalars from the output
scalarsOff->SetInputConnection(selector->GetOutputPort());
scalarsOff->CopyAttributeOff(vtkMaskFields::POINT_DATA,
vtkDataSetAttributes::SCALARS);
scalarsOff->CopyAttributeOff(vtkMaskFields::CELL_DATA,
vtkDataSetAttributes::SCALARS);

vtkSmartPointer<vtkGeometryFilter> geometry =
vtkSmartPointer<vtkGeometryFilter>::New();

geometry->SetInputConnection(scalarsOff->GetOutputPort());
geometry->Update();

vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(geometry->GetOutputPort());
mapper->ScalarVisibilityOff();
mapper->Update();

vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();

vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);

        vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();

renderWindow->AddRenderer(renderer);
renderer->SetBackground(.2, .3, .4);

vtkSmartPointer<vtkActor> actor =
vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
renderer->AddActor(actor);

renderer->ResetCamera();

renderWindow->Render();
renderWindowInteractor->Start();


Thanks,
Tejas

Subject: [vtkusers] vtkImageAlgorithm output to preallocated buffer
Message-ID: <7A829733-91F6-4B75-9E48-75B61A3AF008@gmail.com>

I'm using vtkImageReslice to obtain a vtkImageData object that I read the output scalars from. All works fine.
I'm now in a situation where it would make sense that I preallocate thee output buffer for the reslice to write into.
Is there a way to do this? 
I thought I'd create a vtkImageData and SetScalarPointer on it, then SetOutput on the reslice. But I haven't been able to.
Is there a way I could do this? Maybe I should create a vtkImageData subclass?
Thanks,
Alessandro

Instead of subclassing vtkImageData, it might be better to subclass
vtkImageReslice and override the AllocateOutputData() methods.  See the
current implementation of AllocateOutputData() here:
https://gitlab.kitware.com/vtk/vtk/blob/master/Common/ExecutionModel/
vtkImageAlgorithm.cxx#L198

But your idea of calling SetOutput() should work as long as you provide a
large enough output buffer of the correct data type.

I tried this series with vtkDICOMReader and it worked fine (see attached

Hello David, 

thank you very much for your reply, yes, the image result you attached is
right.
but in my code, I fail to  GetNumberOfSeries,  it return 0, below is my
code:
===================================
	vtkSmartPointer<vtkStringArray> filenames =
vtkSmartPointer<vtkStringArray>::New();        
	filenames->InsertNextValue("C:\temp\Data_Fail_to_Read_A\\1-286.dcm");
	filenames->InsertNextValue("C:\temp\Data_Fail_to_Read_A\\1-287.dcm");
	filenames->InsertNextValue("C:\temp\Data_Fail_to_Read_A\\1-288.dcm");
	filenames->InsertNextValue("C:\temp\Data_Fail_to_Read_A\\1-289.dcm");
	filenames->InsertNextValue("C:\temp\Data_Fail_to_Read_A\\1-290.dcm");
	filenames->InsertNextValue("C:\temp\Data_Fail_to_Read_A\\1-291.dcm");
	filenames->InsertNextValue("C:\temp\Data_Fail_to_Read_A\\1-292.dcm");
	vtkSmartPointer <vtkDICOMFileSorter> sorter = vtkSmartPointer
<vtkDICOMFileSorter>::New();
	sorter->SetInputFileNames(filenames);
	sorter->Update();
	*int ns = sorter->GetNumberOfSeries();*    // here ns returns 0, which
should not be.
===================================

and I don't know why sorter->GetNumberOfSeries() returns 0?

Best Regards
James

Hi James,

In the code you sent in your email, there are single backslashes after "C:"
and "temp".  I tried on my computer with proper slashes, and
sorter->GetNumberOfSeries() returns 1.

    reslice->GetOutput()->GetPointData()->SetScalars(vtkSmartPointer<vtkFloatArray>::New());
    reslice->GetOutput()->GetPointData()->GetScalars()->SetVoidArray(myBufferPtr, myBufferBytesLen, 1);

It works fine, but could you explain why in vtkImageData::AllocateScalars we have:

  if (scalars && scalars->GetDataType() == dataType
      && scalars->GetReferenceCount() == 1)

Why does it matter, the ReferenceCount be equal to 1 ?

I didn't know that check was there, but it is checking the reference count
to see if it holds the only reference to data array.  If it does, then it
simply reallocates the array that it has, otherwise it creates a new array.

Your code is creating a loose reference here:


reslice->GetOutput()->GetPointData()->SetScalars(vtkSmartPointer<vtkFloatArray>::New());

The SetScalars() method does not take a smart pointer, so the smart pointer
is being converted into a regular pointer.  The result is exactly the same
as if you called vtkFloatArray::New().

In VTK, you should only call vtkSmartPointer<vtkFloatArray>::New() if you
are assigning the result to a smart pointer.  Otherwise it's a memory
leak.  This is why most smart pointer like std::shared_ptr don't have a
typecast operator to allow them to devolve into regular pointers.  For VTK,
it was decided that the convenience of having a typecast operator was worth
the risk of memory leaks, since we have nightly testing to check for leaks.

To avoid the leak and fix the reference count,

    vtkSmartPointer<vtkFloatArray> scalars =
vtkSmartPointer<vtkFloatArray>::New();
    scalars->SetVoidArray(myBufferPointer, myBufferLen, 1);
    reslice->GetOutput()->GetPointData()->SetScalars(scalars);

And of course you'll have to make sure the smart pointer goes out of scope
before you call Update() on reslice.  To be absolutely sure the reference
count will be one when AllocateScalars is called, do this:

    vtkFloatArray *scalars = vtkFloatArray::New();
    scalars->SetVoidArray(myBufferPointer, myBufferLen, 1);
    reslice->GetOutput()->GetPointData()->SetScalars(scalars);
    scalars->Delete();

One further item of importance is that the "size" for SetVoidArray() is the
number of elements, not the number of bytes.  That's something that has
confused me in the past, and the documentation is not at all clear on that
point.

You can try vtkDICOMDirectory instead of vtkDICOMSorter (they work in much
the same way).  Also, what version of vtkDICOM are you using?

Tejas,

Contours are not aligned to each other well - there is a very visible periodic displacement. You need to do something with this serious problem before trying to reconstruct the surface. If you are reconstructing the volume from a single sweep then the displacements are probably due to cardiac or respiratory motion, so it's not a tracking or calibration issue that you could solve by more careful data acquisition.  I see two main approaches to address this.


A.      Compensate for the displacements. Compute the center-of-gravity of each contour, fit a curve (e.g., polynomial with an order of 2-3) to these center points, then translate each contour so that its center is on the curve. You can then apply VTK's generic-purpose surface reconstruction filters. For a simple tubular shape like a vessel you may simply use vtkDelaunay3D filter to construct a surface and optionally smooth it with vtkWindowedSincPolyDataFilter.

B.      Average displacements. Probably the easiest is to do this in the image domain. Reconstruct a volume from the image slices (you can use the open-source Plus toolkit for this, www.plustoolkit.org<http://www.plustoolkit.org>). Then, segment the vessel on the 3D volume using standard volumetric image segmentation tools (for example, in Segment Editor module in 3D Slicer, www.slicer.org<http://www.slicer.org>).

The 3D volume is constructed from a stack of 2D images/B-scans, and the contour of the vessel in each B-scan has been segmented; that is, I have an ellipse representing the contour of the vessel in each B-scan in the volume. I have tried to reconstruct the contour of the vessel by following the VTK example of 'GenerateModelsFromLabels.cxx' (http://www.vtk.org/Wiki/VTK/Examples/Cxx/Medical/GenerateModelsFromLabels).

It is discontinuous and irregular, and the surface doesn't connect the vessel contours between two adjacent frames in the volume if the displacement between the ellipses is large. In my approach, I basically used DiscreteMarchingCubes -> WindowedSincPolyDataFilter -> GeometryFilter.

I played around with the passband, smoothingIterations and featureAngle parameters, and I was able to obtain the best following result:

As you can see, it is not a smooth continuous surface with a lot of uninterpolated "holes" between adjacent frames, but it is all right. Can it be made better? I also tried using a 3D Delaunay triangulation, but it only gave me the convex hull, which is not the output I expected. I would like to know if there is a better approach towards reconstructing a surface that closely follows the contour of the vessel from one B-scan to the next in a volume?

                        if (z == 0)

Subject: [vtkusers] Get pointer coordinates in vtkChart axes
Message-ID: <1485201331376-5741920.post@n5.nabble.com>

Dear all, 
I am trying to access the coordinate of the mouse pointer when clicking on a
vtkChartXY, expressed in the chart coordinates. Only one data series is
plotted so there is only one Y axis to worry about.

I am subclassing vtkInteractorStyleTrackballCamera and displaying the
coordinates of the mouse click expressed in the window frame. That is, for a
vktChartXY displayed in a 400 x 400 render window, clicking at the very
center of the chart would return (200,200).

The vtk class vtkCoordinate seems to be capable of coordinates transforms
between the raw figure coordinates and other frames of reference, but I have
yet to find a way to transform the pixel coordinates to the chart
coordinates. 

Any advice?

Thanks!

Subject: [vtkusers] Improving visualization of geometric shapes
Message-ID: <1485243126581-5741921.post@n5.nabble.com>

Dear VTK Users,

I have been using VTK for a montly and I noticed that it is the best
visualization tool. For my PhD, I am trying to visualize hundreds of
ellipsoids and some point clouds using VTK. So far, I visualized ellipsoids
and point clouds successfully as shown in the attached figure. However, it
has to be developed. Without some shading and lighting effects it is
impossible to distinguish individual ellipsoids (shown by green). For
example, there are a few ellipsoids at upper left but they cannot be
distinguished. Could you please help me about this problem? How can I make
them distinguishable? 
I am looking forward to hearing from you.

Subject: [vtkusers] Problem using vtkDicomWriter
Message-ID: <CAJ0hFr=6h+DvB2n4bzEME0rATh9kFBkeXaH9gDL9n8N8ggffLA@mail.gmail.com>

Hi,

I'd like to use the vtkDICOMWriter class to convert a vtkImage to a set of
DICOM images.

I've compile VTK with the vtkDICOM module enabled and followed the example
from the pdf found on the github repository (
http://dgobbi.github.io/vtk-dicom/doc/vtk-dicom.pdf).


The image data is created like this :

    auto  img = vtkSmartPointer < vtkImageData >::New();
    img->SetOrigin(0, 0, 0);
    img->SetDimensions(1024, 1024, numlayer);
    img->SetSpacing(1, 1, 1);
    img->AllocateScalars(VTK_UNSIGNED_SHORT, 1);

and the data filled like this :

           for (int n = 0; x < numlayer; n++) {
                for (int x = 0; x < 1024; x++) {
                    for (int y = 0; y < 1024; y++) {
                        char* pixel =
static_cast<char*>(img->GetScalarPointer(x, y, n));
                        pixel[0] = values[x][y];
                    }

I can load the converted result with paraview without problems.
But with 3D Slicer, I can just load the first file of the serie and it
display a blank image.

What do I have to do to be able to load the images with both application ?

Thanks,

Eddy

Hi Eddy,

Can you provide the code that you used to write the image with
vtkDICOMWriter?  Here is an example:
http://dgobbi.github.io/vtk-dicom/doc/api/image_writer.html

Creating an image with a loop that calls GetScalarPointer() for every pixel
is not very efficient, and casting to a "char *" when the data is "unsigned
short" is wrong: you are setting only 8 bits of each 16-bit pixel, while
leaving the other 8 bits uninitialized.  The vtkImageImport filter is a
better way of generating image data:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Images/ImageImport

Folks,

Will Schroeder has added a number of new filters to process point
clouds. These are exciting additions to VTK.

We have added number of new wiki examples that illustrate some of the
new point cloud filters:

Surface extraction
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Points/ExtractSurface

Extract clusters http://www.vtk.org/Wiki/VTK/Examples/Cxx/Points/ExtractCluster

Estimate normals
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Points/NormalEstimation

Select points near an implicit function
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Points/FitImplicitFunction

Add points to a point cloud
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Points/DensifyPoints

Compute signed and unsigned distances to a point cloud
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Points/SignedDistance
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Points/UnsignedDistance

Enjoy,

Bill

Subject: [vtkusers] Picking composite/hybrid actors such as vtkAxesActor
Message-ID: <2b6c9c2c-42a4-6e67-0e00-2a6b13be94dd@umontpellier.fr>

Hello,

I write you because I have troubles to manage to pick "composite/hybrid" 
actors comprising :
- 1 vtkActor
- 1 vtkCaption2D actor

I followed the same design as the "vtkAxesActor" class to create a class 
which contains 2 actors :
- vtkActor which represents a sphere constructed with a vtkSphereSource
- Alabel (a vtkCaptionActor2D actor).

=> I would like to be able to pick these composite/hybrid actors with an 
interactor style such as "vtkInteractorStyleRubberBandPick" in order to 
move their position, reoriente them interactively etc.

But unfortunately, the area picker never returns one of these 
composite/hybrid objects when calling areaPicker->GetProp3Ds();
(it finds well conventional vtkActors containing polydata only though)

One illustration is on the following image:
http://morphomuseum.com/img/picking.jpg
1) I manage to pick with no problem the "actor" containing the largest 
yellow structure (once picked I can change its orientation-position 
etc...).
2) I can't pick anly of the composite/hybrid actors (the red spheres 
associated with a number = 3D landmarks)

Would you have an advice to make it possible to pick composite 3D 
structures containing  polydata+ associated text ?
Many thanks in advance.
Best wishes,
Renaud.

Subject: [vtkusers] 3D Surface or Volume
Message-ID: <CAGs-pZXjz4ch7hC0DS=rp+X7G6maRpuXcmDumRiL5xQMr82o0g@mail.gmail.com>

Hi,

I have 2 surfaces (3D mesh) of the same object: the upper surface and the
lower surface. Each object is stored in a obj file.
I read the 2 surfaces and render them in the render window. However, I want
to create a closed surface or a volume from these surfaces.
I have tried with delaunay 3D but the obtained result does not correspond
to what I want: it creates a convex hull.
I also tried to use Surface Reconstruction Filter, but the result was not
acceptable.
Can any one tell me what kind of filters I have to use?

Thank you very much.

Sincerely,

Paulo

If the two surfaces are aligned properly, you could use
vtkAppendPolyDataFilter followed by vtkCleanPolyData

Hi Everyone,

I am pretty new to VTK. The question is regarding adding vtk functionality
to existing openGL context. I searched about
*vtkExternalOpenGLRenderWindow. *What I found was that the header was
located in Renderer - > External and was not automatically included in
include files with cmake. But even after "including" the file manually
vtkRenderingExternalModule.h is missing. I tried searching in Source but
couldn't find it. I downloaded again the source (zip)(7.0.0) but still
couldn't find it. Does any one know how to get access to this header and
successfully add it to project.

Thanks a lot

Hi Megha,

You?d have to enable the module in CMake when compiling VTK.

-DModule_vtkRenderingExternal:BOOL=ON

?

Hi David,

Here's the code below. This is almost the example of the api doc :

    auto generator = vtkSmartPointer <vtkDICOMCTGenerator>::New();
    vtkSmartPointer <vtkDICOMMetaData> meta = vtkSmartPointer
<vtkDICOMMetaData>::New();

    meta->SetAttributeValue(DC::PatientName, "Test");
    meta->SetAttributeValue(DC::PatientID, "0000001");
    meta->SetAttributeValue(DC::ScanOptions, "");
    meta->SetAttributeValue(DC::ScanningSequence, "GR");
    meta->SetAttributeValue(DC::SequenceVariant, "SP");
    meta->SetAttributeValue(DC::ScanOptions, "");
    meta->SetAttributeValue(DC::MRAcquisitionType, "2D");

    vtkSmartPointer <vtkDICOMWriter> dicom_writer =
        vtkSmartPointer <vtkDICOMWriter>::New();
    dicom_writer->SetInputData(img);
    dicom_writer->SetMetaData(meta);
    dicom_writer->SetGenerator(generator);
    dicom_writer->SetSeriesDescription("Sagittal Multi-planar Reformat");

    // Set the output filename format as a printf-style string.
    dicom_writer->SetFilePattern("%s/IM-0001-%04.4d.dcm");
    // Set the directory to write the files into.
    dicom_writer->SetFilePrefix(path.toStdString().c_str());
    // Write the file.
    dicom_writer->Write();

Sorry, the use of an unsigned short type was a carreless mistake. The
result is better with unsigned char,
but I still see just one image of the serie on 3D Slicer. Is there
something missing to have a complete serie ?

I didn't know the vtkImageImport and I'll give it a try.

Thanks,

Eddy

If the two surfaces are aligned properly, you could use

Hi Eddy,

The code is using a vtkDICOMCTGenerator to write an MR image, which is
definitely wrong.  Use the vtkDICOMMRGenerator, and make sure the meta data
matches the IOD:
http://dicom.nema.org/medical/dicom/current/output/chtml/part03/sect_C.8.3.html

The standard says that BitsAllocated must be 16 for MR images, therefore an
8-bit MR image is non-standard and DICOM software may to refuse to display
it.  You should convert your data to 16-bit (In fact, it seems fishy that
you are working with unsigned char, since if you are writing a reformat of
an MR image, then wasn't the original MR image a 16-bit image?)

I can't answer about why Slicer is only showing one slice, as I don't
currently have Slicer installed.

Subject: [vtkusers] Correctly exporting dependency on VTK in CMake
	ProjectConfig
Message-ID: <ed1cfaac-1cfe-52a6-f890-1f2f29a47479@ovgu.de>

Hi vtkusers,

I am developing a small C++ library that is dependent on some components
of VTK. I am using CMake to build my library, and I am providing a
ProjectConfig.cmake file to make it easier to use my library with CMake.
My ProjectConfig file is structured according to the example at
https://cmake.org/Wiki/CMake/Tutorials/How_to_create_a_ProjectConfig.cmake_file.
This means when installing, I am creating a ProjectTargets.cmake file
that contains my library plus all the libraries that my lib depends on.
I should also mention that I am on Linux and am using VTK 7.1 and CMake 3.4.

My problem is that this file does not contain the path of the vtk
libraries I depend on, only their names. When I build my project, this
is not a problem, as it knows the VTK link directory (via
find_package(VTK)). However, when I use my lib in another CMake project,
the VTK library path is not available any more (The other project does
not and should not need to find VTK itself). This leads to lots of
library not found errors when linking.

Here is how my CMake Project is structured:

Main CMakeLists.txt (almost 1:1 copy&paste from the Wiki example):
------------------------------------------------------------------------
[...]
add_subdirectory(src)

export(TARGETS my_lib
    FILE "${PROJECT_BINARY_DIR}/MyProjectTargets.cmake")

# export(PACKAGE MyProject)

file(RELATIVE_PATH REL_INCLUDE_DIR
    "${INSTALL_CMAKE_DIR}" "${INSTALL_INCLUDE_DIR}")

set(CONF_INCLUDE_DIRS "${PROJECT_SOURCE_DIR}" "${PROJECT_BINARY_DIR}")
configure_file(MyProjectConfig.cmake.in
    "${PROJECT_BINARY_DIR}/MyProjectConfig.cmake" @ONLY)

set(CONF_INCLUDE_DIRS "\${MYPROJECT_CMAKE_DIR}/${REL_INCLUDE_DIR}")
configure_file(MyProjectConfig.cmake.in

"${PROJECT_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/MyProjectConfig.cmake" @ONLY)

configure_file(MyProjectConfigVersion.cmake.in
    "${PROJECT_BINARY_DIR}/MyProjectConfigVersion.cmake" @ONLY)

install(FILES
   	"${PROJECT_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/MyProjectConfig.cmake"
    "${PROJECT_BINARY_DIR}/MyProjectConfigVersion.cmake"
    DESTINATION "${INSTALL_CMAKE_DIR}" COMPONENT dev)

install(EXPORT MyProjectTargets
    DESTINATION "${INSTALL_CMAKE_DIR}" COMPONENT dev)
------------------------------------------------------------------------

src/CMakeLists.txt:
------------------------------------------------------------------------
set(SOURCES ...)

set(HEADERS ...)

add_library(my_lib ${SOURCES} ${HEADERS})

...

find_package(VTK REQUIRED COMPONENTS vtkParallelMPI vtkIOParallelXML
NO_MODULE)
if(VTK_FOUND)
    include(${VTK_USE_FILE})
    target_link_libraries(my_lib ${VTK_LIBRARIES})
endif()

...

install(TARGETS my_lib
    EXPORT MyProjectTargets
    LIBRARY DESTINATION "${INSTALL_LIB_DIR}" COMPONENT lib
    ARCHIVE DESTINATION "${INSTALL_LIB_DIR}" COMPONENT lib
    PUBLIC_HEADER DESTINATION "${INSTALL_INCLUDE_DIR}/my_lib" COMPONENT dev)
------------------------------------------------------------------------

This works fine and I can use find_package(MyProject) in some other
CMake project to use my lib. The generated
MyProjectTargets-release.cmake file contains a statement to set up the
dependencies of my lib looking like this:
------------------------------------------------------------------------
# Import target "my_lib" for configuration "Release"
set_property(TARGET my_lib APPEND PROPERTY IMPORTED_CONFIGURATIONS RELEASE)
set_target_properties(my_lib PROPERTIES
  IMPORTED_LINK_INTERFACE_LIBRARIES_RELEASE
"/some/path/lib64/libmpi.so;/some/path/lib64/libmpigc4.so;/usr/lib64/libdl.so;/some/path/intel64/libirc.so;/usr/lib64/libpthread.so;/usr/lib64/librt.so;[...];vtkParallelMPI;vtkCommonCore;vtksys;vtkCommonDataModel;vtkCommonMath;
vtkCommonMisc;vtkCommonSystem;vtkCommonTransforms;vtkParallelCore;
vtkIOLegacy;vtkCommonExecutionModel;vtkIOCore;vtkzlib;vtkIOParallelXML;
vtkIOXML;vtkIOXMLParser;vtkexpat"
  IMPORTED_LOCATION_RELEASE "/some/path/MyProject/lib/my_lib.so"
  IMPORTED_SONAME_RELEASE "my_lib.so"
  )
------------------------------------------------------------------------
As you can see, all the dependent libraries listed are given with their
full path, except for the vtk ones. Since they are installed in a
non-standard location, the linker will not find them unless explicitly
told where to look. There is however no reference to the path they
reside in anywhere in that file.

Where is the error? Does the VTKConfig.cmake file that is used when
find_package(VTK) is called export its targets incorrectly? Did I forget
to export something in my CMake script (it worked without that for all
my other dependencies)? Do I have to add the VTK lib path to some
environment variable so the linker finds it (I tried both LIBRARY_PATH
and LD_LIBRARY_PATH to no effect)?

I hope this question is not too complex, but I guess if anybody knows
how to do ProjectConfig right it's the VTK developers.

Best,

Timo

Subject: [vtkusers] vtkAppendPolyData RemoveInputData leads to 0 connections
Message-ID: <2c40e4592bb9494ca30134ddb079aa69@SIMAIL13.stemmer.local>

Hi,

it seems to be an easy issue, but I don't get the solution. I am appending multiple vtkPolyData to vtkAppendPolyData:

vtkSmartPointer<vtkAppendPolyData> appendFilter = vtkSmartPointer<vtkAppendPolyData>::New();
appendFilter->AddInputData(polyData1);
appendFilter->AddInputData(polyData2);

In another functions I want to hide / show those polydata:

Function to hide:
appendFilter->RemoveInputData(polyDataX);
appendFilter->Update();

Function to show:
appendFilter->AddInputData(polyDataX);
appendFilter->Update();

This works fine, unless I have only one polydata in the vtkAppendPolyData filter. If I hide (see Function to hide) this last polydata I get following error after appendFilter->Update():
Input port 0 of algorithm vtkAppendPolyData has 0 connections.

The error message is clear, but how would you solve this? Is there a better way to do that?

Thank you very much in advance!

Sincerely,

Bea

If you drag-and-drop a single image slice into Slicer then by default it will load that single image slice. How to load the full volume from DICOM:

Option A: Drag-and-drop the directory that contains your DICOM files to the Slicer main window. Slicer offers to import them, accept that option, wait for the import to complete, then select the data set in the DICOM browser and load it.

Option B: Drag-and-drop a single DICOM file to Slicer. You have the option to load that single slice (default behavior), or check ?Show Options? in the top-right corner and uncheck ?Single File? option in the table.

Sorry, the use of an unsigned short type was a carreless mistake. The result is better with unsigned char,
but I still see just one image of the serie on 3D Slicer. Is there something missing to have a complete serie ?
I didn't know the vtkImageImport and I'll give it a try.

Hi Eddy,

Can you provide the code that you used to write the image with vtkDICOMWriter?  Here is an example:
http://dgobbi.github.io/vtk-dicom/doc/api/image_writer.html

Creating an image with a loop that calls GetScalarPointer() for every pixel is not very efficient, and casting to a "char *" when the data is "unsigned short" is wrong: you are setting only 8 bits of each 16-bit pixel, while leaving the other 8 bits uninitialized.  The vtkImageImport filter is a better way of generating image data:

I've compile VTK with the vtkDICOM module enabled and followed the example from the pdf found on the github repository (http://dgobbi.github.io/vtk-dicom/doc/vtk-dicom.pdf).


The image data is created like this :

    auto  img = vtkSmartPointer < vtkImageData >::New();
    img->SetOrigin(0, 0, 0);
    img->SetDimensions(1024, 1024, numlayer);
    img->SetSpacing(1, 1, 1);
    img->AllocateScalars(VTK_UNSIGNED_SHORT, 1);
and the data filled like this :

           for (int n = 0; x < numlayer; n++) {
                for (int x = 0; x < 1024; x++) {
                    for (int y = 0; y < 1024; y++) {
                        char* pixel = static_cast<char*>(img->GetScalarPointer(x, y, n));
                        pixel[0] = values[x][y];
                    }

I can load the converted result with paraview without problems.
But with 3D Slicer, I can just load the first file of the serie and it display a blank image.
What do I have to do to be able to load the images with both application ?

Thanks,
Eddy

Hi Bill,

thank you very much, but I forgot to mention, that the last vtkPolyData is not removed then.

Sorry for this missing piece of information.

Hi,

it seems to be an easy issue, but I don?t get the solution. I am appending multiple vtkPolyData to vtkAppendPolyData:

vtkSmartPointer<vtkAppendPolyData> appendFilter = vtkSmartPointer<vtkAppendPolyData>::New();
appendFilter->AddInputData(polyData1);
appendFilter->AddInputData(polyData2);

In another functions I want to hide / show those polydata:

Function to hide:
appendFilter->RemoveInputData(polyDataX);
appendFilter->Update();

Function to show:
appendFilter->AddInputData(polyDataX);
appendFilter->Update();

This works fine, unless I have only one polydata in the vtkAppendPolyData filter. If I hide (see Function to hide) this last polydata I get following error after appendFilter->Update():
Input port 0 of algorithm vtkAppendPolyData has 0 connections.

The error message is clear, but how would you solve this? Is there a better way to do that?

Thank you very much in advance!

Sincerely,

Subject: [vtkusers] VTK web application
Message-ID: <CAMgLW4K5Wvt6PFZE1qgpkoNy+hTvEtLd6aL+CRz-RAdsBa+LaA@mail.gmail.com>

Hello,

I've been developing a VTK/Qt desktop application for a while now. It uses
vtkGraphLayoutView and other Infovis components. I'm looking in to what it
would take to create a web application that provides similar functionality.

What is the recommended solution or starting point? I see several
possibilities available: ParaViewWeb/Visualizer, LightViz, vtk.js. Would it
be LightViz, because it allows for a tailored user interface?

Both the ParaViewWeb and LightViz documentation say that they are meant for
scientific visualization, and among all of the screenshots and examples I
don't see any graphs. Does that mean it doesn't support the
rendering/interaction of vtkGraphs? Would I need to add that support
myself? Or does it just treat it as a vtkPolyData?

I appreciate any guidance.

Eric Stanton

Hello everyone,

I found several PLY files which crashed my ParaView based application. I
inspected vtkPLYReader.cxx and found that it doesn't support loading of PLY
files with points.

Example of such PLY file:
https://courses.cs.washington.edu/courses/cse558/01sp/software/scanalyze/points.html
Example of software which successfully opens such PLY file: CloudCompare -
http://www.danielgm.net/cc/

Do you maybe have in plans adding support, to vtkPLYReader.cxx, for such
PLY files?

Thanks in advance,
Nenad.

Hi Eric,

We used to have an example for vtkWeb using the graph view here:
https://github.com/Kitware/VTK/tree/v7.0.0/Web/Applications/GraphLayout

Since ParaView does not provide any proxy for the vtkGraphLayoutView, you
most likely will have to stick with VTK on the server side.

But between VTK 7.0 to 7.1, we removed all the JavaScript code from the VTK
repository and created a dedicated JavaScript repo here (
https://github.com/kitware/paraviewweb).

Even if we mostly use it with a ParaView server, you can still create a
vtkWeb application based on it. We have some explanations here (
http://kitware.github.io/paraviewweb/examples/RemoteRenderer.html) where
the code was taken from (
https://github.com/Kitware/VTK/tree/v7.0.0/Web/Applications/Cone).

Hopefully from those examples, you will be able to redo our old GraphLayout
example with the new code base. And see how to go forward based on your
needs.

Seb

Bill,

Thank you very much for your help! Your patch works great! Now, I can load

I'm getting (very often but randomly) segfault on vtkXOpenGLRenderWindow::MakeCurrent

on glXMakeCurrent

Linux, Nvidia, mesa 13.0.3

VTK 7.0

What are possible reasons? How can I deduce it? Thank you!

Hi,

I have a .vtk polydata file which I load into my program with the vtkGenericDataObjectReader. The surface looks good but the triangles are visible to the unaided eye. When I import the same .vtk file into the tool "FreeSurfer ( Software Suite for Brain MRI Analysis)" the surface looks much better and there are no single triangles visible. When I enable "show mesh" in Freesurfer the triangle points are visible, but the surface itself is much better than in my VTK program.

How I can improve/interpolate my data to improve the surface look?

Thank you!<https://www.dict.cc/englisch-deutsch/visible.html><https://www.dict.cc/englisch-deutsch/eye.html>

Hello David,

I used the vtkDICOMMRGenerator filter, unsigned short instead of unsigned
char and add this line :

     meta->SetAttributeValue(DC::SpacingBetweenSlices, "1");

The BitsAllocated has now a value of 16 but I've got the same result.

Thanks to the tips given by Andras, I've opened each slice individually and
they seems correct.

There's definitly something wrong in my files, but I don't see why.

Thanks.

Eddy

Hi Andras,

I didn't manage to load un single image before.

Thank you for the tip.

Random crashes are often caused by memory overwrites. Try to use valgrind
on your program, maybe you'll see something.
Also, try to run your program on a different machine with a different
OpenGL driver. Do you get the same?

Hi Eddy,

In Slicer's DICOM browser, does it show all of the images as belonging to
the same series?  I'm wondering if, perhaps, each image has a different
SeriesInstanceUID.  That would definitely cause problems with loading into
a "dicom aware" program like Slicer, but ParaView probably wouldn't care.

Also in VTK 7.0 there were cases where when working with multiple windows
or removing actors/mappers/textures from a live window could cause this
type of error. If you have just one window and are not removing
actors/mappers/textures from it then I'm not sure what it is.

Hi David,

When I load the DICOM directory, Slicer tells me that there's only one
serie.
Each image have the same SeriesInstanceUID.

I don't know if it's normal but the SeriesInstanceUID is also used for the
SOPInstanceUID, the StudyInstanceUID and the FrameOfReferenceUID.

I've made a screenshot of the Slicer metadata browser here :

Hi Eddy,

The SOPInstanceUID must be different for each image (and the other two UIDs
shouldn't be the same as the SeriesInstanceUID, either).

What version of vtk-dicom are you using, and what operating system?  I can
check on my end to make sure that the random numbers for the UUIDs are
being properly generated.  I use CryptGenRandom() on Windows and
/dev/urandom on UNIX/Linux.

Subject: [vtkusers] how to move an actor by keyboard events
Message-ID: <CA+aY+=BFNR1s3GAa5Bucisps5kZgB=-hnPBLRCkSyt+PN4dfjQ@mail.gmail.com>

Hello Everyone,



I want to use arrow keys to move an actor in a scene. The actor is created
from an STL reader from the following code:



       vtkSmartPointer<vtkSTLReader> reamer_reader =

              vtkSmartPointer<vtkSTLReader>::New();

       reamer_reader->SetFileName(inputFilename.c_str());

       reamer_reader->Update();



Then, I have the following transfer matrix and filter to make the
translations:



       vtkSmartPointer<vtkTransform> transform_matrix = vtkSmartPointer<
vtkTransform>::New();

       transform_matrix->Translate(0.0, 0.0, 0.0);

       vtkSmartPointer<vtkTransformPolyDataFilter> transformFilter =

              vtkSmartPointer<vtkTransformPolyDataFilter>::New();

       transformFilter->SetInputConnection(reamer_reader->GetOutputPort());

       transformFilter->SetTransform(transform_matrix);

       transformFilter->Update();



And of course, there are the mapper, actor and renderer as follows:


       vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer
>::New();

       renderer->SetBackground(.3, .6, .3);

       vtkSmartPointer<vtkPolyDataMapper> reamer_mapper = vtkSmartPointer<
vtkPolyDataMapper>::New();

       reamer_mapper->SetInputConnection(reamer_reader->GetOutputPort());

       vtkSmartPointer<vtkActor> reamer_actor = vtkSmartPointer<vtkActor
>::New();

       renderer->AddActor(reamer_actor);



I create a window interactor and then add an observer to look for key press
events:


       vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =

              vtkSmartPointer<vtkRenderWindowInteractor>::New();

       vtkSmartPointer<vtkInteractorStyleTrackballCamera> camera_style =

              vtkSmartPointer<vtkInteractorStyleTrackballCamera>::New();

       renderWindowInteractor->SetInteractorStyle(camera_style);

       vtkSmartPointer<vtkCallbackCommand> keypressCallback =

              vtkSmartPointer<vtkCallbackCommand>::New();

       keypressCallback->SetCallback(KeypressCallbackFunction);

       renderWindowInteractor->AddObserver(vtkCommand::KeyPressEvent,
keypressCallback);

       vtkSmartPointer<KeyPressInteractorStyle> keyboard_style =

              vtkSmartPointer<KeyPressInteractorStyle>::New();

       renderWindowInteractor->SetInteractorStyle(keyboard_style);

       vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<
vtkRenderWindow>::New();

       renderWindowInteractor->SetRenderWindow(renderWindow);

       renderWindow->AddRenderer(renderer);

       renderWindow->Render();

       renderWindowInteractor->Start();




and here is the KeypressCallbackFunction itself:



void KeypressCallbackFunction(vtkObject* caller,

       long unsigned int vtkNotUsed(eventId),

       void* vtkNotUsed(clientData),

       void* vtkNotUsed(callData)){



       vtkRenderWindowInteractor *iren = static_cast<
vtkRenderWindowInteractor*>(caller);



       std::cout << "Pressed: " << iren->GetKeySym() << std::endl;



       std::string key = iren->GetKeySym();





       if (key == "Up") {



              //??? What to do here ???



       }



}



I can not figure out what commands should I write when the ?Up? key is
pressed. I am assuming that I only need to update the translation matrix
here, but I don?t know where to apply the updated translation matrix to the
actor and I think I need to call renderWindow->Render(), too. I will really
appreciate it if anyone helps me with

(1)      what to write within the if-block?

(2)      how to pass variables such as translation matrix to
KeypressCallbackFunction?

(3)      where to call  renderWindow->Render()?



Many thanks!

It's very strange but dowgrading nvidia driver from 378.09 (where they enabled multithread optimizations) helped me there...

I will wait for more people to confirm whether it's related or not but sumhow problem is disappeared after downgrade gpu driver for me

Hi David,

I've patched my vtk 7.1 source and recompile and that's working. I can load
my dicom directory in Slicer without problems now.

I've surely faced a corner case, but after reading the documentation (
https://msdn.microsoft.com/en-us/library/windows/desktop/
aa379886(v=vs.85).aspx), I think it's maybe safer to use the
CRYPT_VERIFYCONTEXT flag.

Thanks for your help.

Eddy

Subject: [vtkusers] Can I generate DRR image from DICOM slices series using
	vtk??
Message-ID: <1485544533819-5741974.post@n5.nabble.com>

Hallo,  I want to generate DRR from DICOM slices but I don't know if there
are frameworks in vtk for that purpose?

Thanks

Subject: [vtkusers] Struggling with ColorCellsWithRGB example and Python
Message-ID: <CAGL8XstqtU1U2c=3zc0aUehd9Lj8HX69EZub_tsWmF77tBEcgA@mail.gmail.com>

Hello,

I'm relatively new to VTK and I'm running into an issue with a VTK example
and Python (running VTK 6 and Python 3.6 on Win7 x64).  I've got an STL
file where I want to set certain cells to a given color.  I've got the cell
IDs (through ray casting) and colors using a colormap from matplotlib.
>From what I can tell, the ColorCellsWithRGB example should allow me to set
certain triangles to a given color.  My current issue is the mesh is
rendering black given the below code.  If I comment out the 'InsertTuples"
line and uncomment the "InsertNextTuple3" line, triangles are represented
different colors; however, it's random and looks like a kaleidoscope when
it should be monochromatic. FWIW, my STL images render fine when not using
the SetScalars command.  Can someone give me pointers on what I can look at
next so that I can achieve my goals?*.*

class Mesh:
    def __init__(self):
        self.MeshData = None
        self.__OldMeshData = None
        self.FileName = None
        self.Name = None

    def LoadSTL(self, filenameSTL):
        readerSTL = vtk.vtkSTLReader()
        readerSTL.SetFileName(filenameSTL)
        # 'update' the reader i.e. read the .stl file
        readerSTL.Update()
        polydata = readerSTL.GetOutput()
        # If there are no points in 'vtkPolyData' something went wrong
        if polydata.GetNumberOfPoints() == 0:
            raise ValueError(
                "No point data could be loaded from '" + filenameSTL)
            return None

        self.MeshData = polydata
        self.FileName = filenameSTL
        self.Name = self.FileName
        return polydata




cellData = vtk.vtkUnsignedCharArray()
cellData.SetNumberOfComponents(3)
cellData.SetNumberOfTuples(laa.MeshData.GetNumberOfCells())
cellData.SetName('Colors')
for i in range(0,laa.MeshData.GetNumberOfCells()):
    cellData.InsertTuple(i,(.5,.5,.5))
    #cellData.InsertNextTuple3(.5,.5,.5)

laa.MeshData.GetCellData().SetScalars(cellData)
laa.MeshData.Modified()

Sorry about this.  I've been staring at code all day where color values are
scaled between 0 and 1.  After three hours of banging my head, I've realized
color values, for this function, are scaled between 0 and 255.  Dumb
mistake.

Subject: [vtkusers] Faster way to create a vtkImageData with a single value
Message-ID: <1485718656726-5741978.post@n5.nabble.com>

Hello,

I am working in creating volume images from PolyData using
vtkPolyDataToImageStencil and vtkImageStencil.
The process is outline here:[1] (for 2D images).
To do this, you need to fill a vtkImageData with a background (or
foreground) value.
Something like this:

    imgvtk = vtk.vtkImageData()
    imgvtk.SetSpacing(spacing)
    imgvtk.SetOrigin(origin)
    imgvtk.SetExtent(extent)
    imgvtk.AllocateScalars(vtk.VTK_UNSIGNED_CHAR, 1)
    
    # fill vtk image with background
    count = imgvtk.GetNumberOfPoints()
    for i in range(count):
        imgvtk.GetPointData().GetScalars().SetTuple1(i, backgroud_value);


However, this is very very slow, by far the slowest part of the process.  Is
there a faster way to do this?


Full code:
import vtk
from vtk.util import numpy_support

def pd_to_numpy_vol(pd, spacing=[1.,1.,1.], shape=None, origin=None
foreground_value=255, backgroud_value = 0):
    if shape is None:
        bnds = np.array(pd.GetBounds())
        shape = np.ceil((bnds[1::2]-bnds[::2])/spacing).astype(int)+15
    if origin is None:
        origin = bnds[::2]+(bnds[1::2]-bnds[::2])/2

    #make image
    extent = np.zeros(6).astype(int)
    extent[1::2] = np.array(shape)-1
    imgvtk = vtk.vtkImageData()
    imgvtk.SetSpacing(spacing)
    imgvtk.SetOrigin(origin)
    imgvtk.SetExtent(extent)
    imgvtk.AllocateScalars(vtk.VTK_UNSIGNED_CHAR, 1)
    
    # fill vtk image with background
    count = imgvtk.GetNumberOfPoints()
    for i in range(count):
        imgvtk.GetPointData().GetScalars().SetTuple1(i, backgroud_value);
    
    #poly2 stencil
    pol2stenc = vtk.vtkPolyDataToImageStencil()
    pol2stenc.SetInputData(pd)
    pol2stenc.SetOutputSpacing(spacing)
    pol2stenc.SetOutputOrigin(origin)
    pol2stenc.SetOutputWholeExtent(extent)
    pol2stenc.Update()
    
    #stencil to image
    imgstenc = vtk.vtkImageStencil()
    imgstenc.SetInputData(imgvtk)
    imgstenc.SetStencilConnection(pol2stenc.GetOutputPort())
    imgstenc.ReverseStencilOn()
    imgstenc.SetBackgroundValue(foreground_value)
    imgstenc.Update()
    
    ndseg =
numpy_support.vtk_to_numpy(imgstenc.GetOutputDataObject(0).GetPointData().GetArray(0))
    return ndseg.reshape(sitk.GetArrayFromImage(seg).shape)

Hi,

A much faster way would be to replace the for loop with this:
imgvtk.GetPointData().GetScalars().Filll(background_value)

Subject: [vtkusers] vtkImageReslice and slab mode
Message-ID: <CAEcL5t4HmRSe9pptZm9LJ+XyvVkW+MyYYHL+dtpc5THZAw_Bug@mail.gmail.com>

Hi David,

I am looking at the vtkImageReslice class to reformat a vtkImageData,
specifically at the slab operations to generate thick slices.

When I set SlabNumberOfSlices to be greater than 1 and SlabSliceSpacingFraction
= 1, I?d expect the output dimensions along the reslice direction to be
less than the input dimensions. But, they come out to be the same. What am
I missing here?

Thank you!

Dear vtk Users,
I write you because I have difficulties to use the anaglyph rendering 
capabilities of the vtkRenderWindow with vtkCaptionActor2D actors.

=> on the example shown at http://morphomuseum.com/img/anaglyph.jpg , I 
have managed to render without any problem anaglyph representations of 
several vtkActors (1 large yellow structure = a monkey's skull  + 
several red spheres = 3D landmarks).

However, the 3D landmark numbers (= vtkCaptionActor2D actors containing 
the text associated with the red spheres) are drawn in plain red.

Many thanks in advance for your help,
Best wishes,
Renaud.

Hi Sankesh,

When I wrote this filter, I decided not to reduce the extent.  Similarly,
if someone uses vtkImageReslice to apply cubic interpolation (which has a
kernel size of 4), I don't remove two slices from each of the 6 faces of
the volume.

Instead, for any kernel-based operation, if any of the kernel samples are
outside of the input volume, then the default behavior is to clamp the
coordinates of those samples to the bounds of the input (the same as what
OpenGL does when you apply CLAMP_TO_EDGE with a texture lookup).  The
vtkImageInterpolator also provides other methods for handling the boundary.

So, in the case you describe, the slab at the boundary will contain repeats
of the outer slice.  To avoid this, you'd have to explicitly set the
OutputExtent yourself, or else override RequestInformation().  It used to
be possible to wire such changes into the pipeline easily via the
ExecuteInformationEvent.

Really, a way to customize RequestInformation() is what is needed here...
almost everyone seems to want something different, depending on their
particular application, and the API for vtkImageReslice is already waaay to
complicated.

 - David

Message-ID: <CAFuWFrL7_Tqg+KJN=M0KqFK23_ocp18-az6jTKJKk0FXUkwzBQ@mail.gmail.com>

Hi everybody,

I am trying to visualize text labels in 3D space. I have successfully used
vtkVectorText + vtkFollower. But the text is scaled as I zoom in /out of my
3D objects (geologic wells, the labels are their names). I have seen that
there is a vtkCaptionActor2D class which displays a fixed-size text
attached to a 3D point. This is almost what I need. The problem is that the
text should get occluded by objects nearer to the camera as I rotate them.
Apparently, the text generated by vtkCaptionActor2D is drawn on top of
everything.
Maybe this is a common issue and I have verified on the list that it has
been discussed before. Can anybody give me some hint on how to do it?
Sorry if I am asking a trivial or recurring question.

  Thank you in advance,

Subject: [vtkusers] vtkImagePlaneWidget and vtkLookupTable being used
	partially?
Message-ID: <CA+RQFfdnPJkbtoeuG89mQwzOW3sxk5bYpq+XcU19k0WM3HG_FQ@mail.gmail.com>

Hi everyone,

I?ve looked at other emails from the mailing list but have not found
anything which explains the problem I?m having.

I have a vtkImageData object with scalars set as a vtkUnsignedCharArray
ranging from 0 to 1. This volume represents rock porosity, with 0 meaning
solid rock and 1 meaning a pore.

I?m using 3 vtkImagePlaneWidget instances, each along one axis, to show 3
plane cuts of the rock.

I?m trying to use a vtkLookupTable to show solid rock as black, and pore as
white:

lookup_table = vtk.vtkLookupTable()
lookup_table.SetNumberOfTableValues(2)
lookup_table.SetTableValue(0, (0., 0., 0., 1.0))
lookup_table.SetTableValue(1, (1., 1., 1., 1.0))

Unfortunately the planes appear as completely black. Changing the color
values to other colors (say, first entry red and second entry blue) has no
effect on the image. If I change the first table entry?s alpha value to
zero though, I can then see the pores of the image as black, which shows
that the data is correct and that the lookup table is being used. It seems
that it is not using the RGB part of the lookup table somehow.

Here?s the relevant part of the code:

self._plane_widgets = []

lookup_table = vtk.vtkLookupTable()
lookup_table.SetNumberOfTableValues(2)
lookup_table.SetTableValue(0, (0., 0., 0., 1.0))
lookup_table.SetTableValue(1, (1., 0., 1., 1.0))
lookup_table.SetTableRange(0., 1.)
for plane_name in ['XY', 'XZ', 'YZ']:
    orientation = vtk_reslice_details.GetVtkPlaneIndexValue(plane_name)
    slice_data = mpr_representation.slices_data[orientation]

    plane_widget = vtk.vtkImagePlaneWidget()
    plane_widget.SetInteractor(vizu.GetInteractor())

    plane_widget.GetPlaneProperty().SetColor(slice_data.norm_color)
    plane_widget.TextureInterpolateOff()
    plane_widget.TextureVisibilityOn()
    plane_widget.SetInputData(vtk_image)
    plane_widget.SetPlaneOrientation(orientation)
    plane_widget.SetSliceIndex(slice_data.slice_index)
    plane_widget.UserControlledLookupTableOn()
    plane_widget.SetLookupTable(lookup_table)

    plane_widget.SetMiddleButtonAction(vtk.vtkImagePlaneWidget.VTK_CURSOR_ACTION)
    plane_widget.SetRightButtonAction(vtk.vtkImagePlaneWidget.VTK_CURSOR_ACTION)

it may be faster if you fill the image matrix in Python and then use
vtkImageImportFromArray to get it into vtk. it would something like:

from vtk.util import vtkImageImportFromArray as viifa
a = np.ones( (3, 4, 5), dtype=np.uint8 ) * BackgroundValue
...
f = viifa.vtkImageImportFromArray()
f.SetArray( a )
f.SetDataOrigin( ... )
f.SetDataSpacing( ... )
f.SetDataExtent( ... )
f.Update()
vimg = f.GetOutput()

--good luck.

Thanks for the clarification, David.

I?ll clip the extents as you suggested.

Subject: [vtkusers] Superpose two vtkImageData with ResliceImageViewer

Hello,

I copy my former message in order to be broadcast in the mailing list :):

I am trying to superpose two vtkImageDatas; one greyscale (DICOM) and
another that is coloured (the dose-map). The dose map is mostly zero, and
using vtkLookUpTable, I used LUT.SetTableValue(0, 0./255., 0./255.,
0./255.,0) so that those voxels are transparent.

The goal is to show the DICOM and place the dose-map over the top (but with
transparent voxels where the dose is zero).

I use vtkResliceImageViewer to visualise the vtkImageData because I am using
python.

I can visualise both the DICOM and the dose-map separately, but I can't
superpose the two. Using the code attached at the end of this post opens two
render windows with strange interactions (scrolling on one window moves
through slices of the second render window).

I imagine my problem comes from reusing the same interactor for two
different vtkResliceImageViewers.

Any ideas?

Thanks in advance.

# Create render window and interactor
renWin = vtk.vtkRenderWindow()
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)

# Read DICOM
directory = vtkDICOMPython.vtkDICOMDirectory()
directory.SetDirectoryName(PathDicom)
directory.Update()

readerDICOM = vtkDICOMPython.vtkDICOMReader()
readerDICOM.SetFileNames(directory.GetFileNamesForSeries(0))
readerDICOM.Update()

# Read dose
readerDose = vtk.vtkMetaImageReader()
readerDose.SetFileName("/home/jonathan/Bureau/DICOMcochon/mhd/holmium.mhd")
readerDose.Update()

# Visualise DICOM
StackViewerDICOM=vtk.vtkResliceImageViewer()
StackViewerDICOM.SetInputData(readerDICOM.GetOutput())
StackViewerDICOM.SetupInteractor(iren)
StackViewerDICOM.SetSliceOrientation(2) #Sur 0 ou 1: vue sagittale ou
coronale

# Visualise dose
StackViewerDose=vtk.vtkResliceImageViewer()
StackViewerDose.SetInputData(readerDose.GetOutput())
StackViewerDose.SetupInteractor(iren)
StackViewerDose.SetSliceOrientation(2) #Sur 0 ou 1: vue sagittale ou
coronale

# Start interactor
iren.Initialize()
iren.Start()

Is there a recommended way to build VTK-7.1.0 with both python 2 and python
3 wrappers?
I am currently doing
cmake -DCMAKE_POSITION_INDEPENDENT_CODE=True -DCMAKE_BUILD_TYPE=Release
-DCMAKE_INSTALL_PREFIX=/vtk-7.1.0 -DVTK_WRAP_PYTHON=ON
-DVTK_PYTHON_VERSION=3.5.1 ../VTK-7.1.0
to get VTK with python 3 wrappers.  It works so long as python 3 is built
with --enable-shared and MESA_GL_VERSION_OVERRIDE=3.2 is set.

Sorry, anaglyph rendering of text works as expected provided that the
vtkCaptionActor2D's color is not plain red (r=1,g=0,b=0) or plain blue.

Message-ID: <766899374.12204896.1485861286413.JavaMail.zimbra@enst.fr>

Hello everyone,

It may be more a dev issue, but I think there is a small mistake in the ComputeBounds() method of vtkImageData
When computing upper bounds, code read (line 781 of vtkImageData.cxx):

this->Bounds[1] = origin[0] + (extent[1-swapXBounds] * spacing[0]);
this->Bounds[3] = origin[1] + (extent[3-swapYBounds] * spacing[1]);
this->Bounds[5] = origin[2] + (extent[5-swapZBounds] * spacing[2]);

Since the upper extent is meant to be the index of the last inside point, this leads to upper bounds excluding the upper fringe of data in each direction.
So I guess this part should read something like:

this->Bounds[1] = origin[0] + ( (extent[1-swapXBounds] + 1) * spacing[0]);
this->Bounds[3] = origin[1] + ( (extent[3-swapYBounds] + 1) * spacing[1]);
this->Bounds[5] = origin[2] + ( (extent[5-swapZBounds] + 1) * spacing[2]);

Am I mistaken ?

Hello!
I'm trying to test vtkOpenFOAMReader.cxx(vtk-6.2) with a sample cavity data.
I got stuck in changing timestep using SetTimeValue().

The result of the following code shows the timestep is not changed at all.
[sehooi at master02 bin]$ test
Scalar range: -4.36666, 4.84854
Scalar range: -4.36666, 4.84854

The expected result is
Scalar range: -4.36666, 4.84854
Scalar range: -4.36666, *4.84853*

Anything wrong in my code?
Thanks in advance.

   vtkSmartPointer<vtkOpenFOAMReader> reader =
vtkSmartPointer<vtkOpenFOAMReader>::New();
   reader->SetFileName("/home/sehooi/cavity/cavity.foam");
   reader->Update();

   reader->SetTimeValue(0.5);

Oh right, thanks for remembering me that!
Does that mean that, if image is displayed, a pick on border of data could return an out-of-bound position value ?

If you use vtkCellPicker, then positions beyond the bounds will not be
picked.  If you use vtkPropPicker, the pick will be based on what is drawn
on the screen, and by default the vtkImageActor and vtkImageSliceMapper
only draw the image out to its bounds (but this can be changed by setting
the "Border" property of the mapper, which causes the border region to be
drawn).

Ok, that's a bit clearer for me now. 
I'm trying to retrieve last voxels indexes of displayed images, through picking world points and the ComputeStructuredCoordinates method.
Unfortunately, since the computed continuous index is rounded down, it never returns the last index before going out of bound.
I will go with my own function for conversion.

Many thanks for the help David!

If you use vtkCellPicker, then positions beyond the bounds will not be
picked.  If you use vtkPropPicker, the pick will be based on what is drawn
on the screen, and by default the vtkImageActor and vtkImageSliceMapper
only draw the image out to its bounds (but this can be changed by setting
the "Border" property of the mapper, which causes the border region to be
drawn).

You need to build it twice. The build does not support using more than
one Python library at a time (even 2.6 vs. 2.7).

Subject: [vtkusers] Where to get Windows binary package/wheel of VTK for
	Python 2.7
Message-ID: <CAPah1Wih4oh4unsVGtk1e3inHL-8j0NAd+zjyrdmDBY2-WJGXQ@mail.gmail.com>

I have been using VTK via the Python bindings, and I am happy to say that
it has worked very well for me. I've noticed that there seems to be an
issue with version 7.0.0 and the Intel HD2000/3000 video cards (
http://public.kitware.com/pipermail/vtk-developers/2016-February/033170.html
).

I understand that a workaround for this is to use a different version of
VTK. However, I am having difficulty finding a Windows compiled package of
VTK 7.1.0 or 6.3.0 that works with Python 2.7. Previously, I had been using
the 7.0.0 wheel file provided by Christoph Gohlke's web site (
http://www.lfd.uci.edu/~gohlke/pythonlibs/#vtk ), but I cannot find the
exact version I want there. I am looking for the following: Python 2.7, VTK
version either 7.1.0 or 6.3.0, and preferably both 32 bit and 64 bit
versions, but either is fine.

Is there any way to get a pre-compiled Windows binary of VTK that I can
install into my instance of Python 2.7?

Alternatively, is there a way for me to convert the standalone Python
windows binaries available through the VTK web site downloads section (
http://www.vtk.org/download/ ) into a package (such as a wheel file) that I
can install in my own instance of Python 2.7?

I've tried using the Anaconda distribution of VTK 7.1.0, but this causes
mysterious problems when I use py2exe. I've also tried compiling VTK on my
own in Windows, but I've had a lot of trouble. I can't get CMake to play
nice with Microsoft Visual C++ Compiler for Python 2.7 (
https://www.microsoft.com/en-us/download/details.aspx?id=44266 ) -- it
can't seem to locate the compiler. If possible, I would prefer to just use
someone else's compiled windows binary Python package.

Thanks!

Subject: [vtkusers] VTK without the V(isualization)
Message-ID: <CADsa1k26FxbjuSu34LutrDiL=t2hMhKLh+btzQo-BY-7vcTbZA@mail.gmail.com>

I understand that VTK is all about visualization (the V), however I am
working on an app that uses VTK in the background and never shows a
renderwindow.  Ok well not quite true as it can/should also be capable of
rendering the same pipleine/steps as the app can also be run with
visualization and manual interaction rendering.  So the app should be
capable with the V and without the V ideally with little to no changes.

Problem I seem to be running into is that some of the code to create say
clip planes using a vtkBoxWidget is not possible without a render window or
inter actor as is my understanding.  When trying to find non visual
"replacements" such as using vtkBoxRepresentation or vtkBox or (put
whatever option here) the api does not seem to have a similar or same api
interface such as GetPlanes() for what I think may be non visual
replacements

So If i use vtkBoxWidget in the V mode.

boxWidget = vtkSmartPointer<vtkBoxWidget>::New();

It works great.  Then I look for a GetPlanes() replacemnt in non V mode here

http://www.vtk.org/doc/nightly/html/functions_g.html#index_g

and find:

GetPlanes() : vtkBoxRepresentation , vtkBoxWidget , vtkClipConvexPolyData ,
vtkFrustumSource

so I try

box = vtkSmartPointer<vtkBoxRepresentation>::New();

and I then get a bizarre warning as at the error window:
Generic Warning: in C\yada\yada\VTK\Rendering\Core\vtkPropety.cxx, line 45
Error: no override found for vtkProperty

The odd part is that at one point I could use vtkBoxRepresentation as a
replacement in the past as it worked.This seems as though I am trying to
create an abstract class or something.

as stack trace yeilds:

>    mydll.dll!vtkSmartPointer<vtkBoxRepresentation>::New() Line 117    C++

where 117 in vtkSmartPointer.h is:

  // Description:
  // Create an instance of a VTK object.
  static vtkSmartPointer<T> New()
    {
117:    return vtkSmartPointer<T>(T::New(), NoReference());
    }

and

     vtkInteractionWidgets-7.0.dll!000007fed708f9ba()    Unknown

before finally going kittywampus at:

     vtkInteractionWidgets-7.0.dll!000007fed708f9ba()    Unknown


Is there any advice for using VTK in both modes "visualized" and "not
Visualized" and just using it as a non visual processing pipeline.


If I try using vtkBox inplace of vtkBoxWidget then I have to start
diverging from the original code pipeline and use AddBounds and what ever
the replacement would be for GetPlanes(clipFunc).

Any thoughts on the problem?

I found the solution using the following code

   reader->UpdateInformation();
   vtkInformation* outInfo =
reader->GetExecutive()->GetOutputInformation(0);
   outInfo->Set(vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEP(), 1.5);
   reader->Update();

instead of

   reader->SetTimeValue(1.5); 
   reader->Update();

Investigating

?GetPlanes() : vtkBoxRepresentation

<http://www.vtk.org/doc/nightly/html/classvtkFrustumSource.html#ad258e57d67508896a08a24c4c9e1b88a>

a little further reveals

virtual vtkPlaneCollection
<http://www.vtk.org/doc/nightly/html/classvtkPlaneCollection.html>*
vtkClipConvexPolyData::GetPlanes ( )

is not the same as

void vtkBoxRepresentation::GetPlanes ( vtkPlanes
<http://www.vtk.org/doc/nightly/html/classvtkPlanes.html> *  *planes*)

and

void vtkBoxWidget::GetPlanes ( vtkPlanes
<http://www.vtk.org/doc/nightly/html/classvtkPlanes.html> *  *planes*)

and hey... why would it be for consistency sake?

or for that matter:

virtual vtkPlanes <http://www.vtk.org/doc/nightly/html/classvtkPlanes.html>*
vtkFrustumSource::GetPlanes ( )

Not that I need a Frustrum.

So I look into vtkClipConvexPolyData and vtkPlaneCollecion to see if I can
get vtkPlanes* and of course I can't.  I get the feeling that vtk is a bit
fractured.

Can someone explain to me why what is seemingly similar things in vtk have
such different interfaces that don't seem to play nice with (itself) it's
own api?
