To answer myself and for anyone else who also might need the vtkTrimmedExtrusionFilter now:


The filter is indeed only part of the vtk nightly version which unfortunately does not work out of the box yet.

But the two files "vtkTrimmedExtrusionFilter.h" and "vtkTrimmedExtrusionFilter.cxx" can be simply copied from the repository and included in a vtk 8.1 program and added to the CMakeLists.txt without any additional work.


Regards,

Berti


PS: If anyone already knows if this will be part of vtk 8.2 it would be nice to know.

Hello everyone.

I stumbled upon the vtkTrimmedExtrusionFilter (https://www.vtk.org/doc/nightly/html/classvtkTrimmedExtrusionFilter.html) which might be very useful for the project i am working on.

Unfortunately when i try to include it, i get a compiler error that the include file could not be found.


Is this filter not yet part of the newest vtk 8.1?

And if so, will it be part of vtk 8.2 or vtk 9.0?


Best regards,

Berti

Subject: [vtkusers] DPI scaling in QVTKWidget
Message-ID: <1538387610923-0.post@n5.nabble.com>

	We are building an application based on QT using QVTKWidget. 

QApplication::setAttribute(Qt::AA_EnableHighDpiScaling); enables automatic
scaling of application except the widget part. 

Can anybody help me with the problem?

Hi,

You may want to use QVTKOpenGLWidget or QVTKOpenGLNativeWidget as
QVTKWidget is now deprecated.

Best,

Mathieu Westphal

Major (8) and minor (2) releases are created from master. So since it is in
master now it will be in 8.2.0.

note: patch releases contain only fixes over an earlier release. Those come
from the release branch.

Thanks for the input everyone.

It seems that noone objects to changing master's name off of 9.0, so I will
go ahead and finish up the merge request
<https://gitlab.kitware.com/vtk/vtk/merge_requests/4700> to reset it to
8.2.0 today.

I'll defer the numbering scheme for subsequent releases for a little while.

Hi David,

thank you very much for the information.

Do you know approximately when VTK 8.2 will be released?


Cheers,

Hi David,

thank you very much again for your reply.

You are right in that the approach of doing rasterization with the graphics card in an offscreen buffer and then reading the pixel values out has its own problems and i stopped going that way.

Even if it didn't sound like that, alltogether i am quite satisfied with the majority voting solution with the vtkPolyDataToImageStencil filter so far. It seems to be precise enough most of the time.

But if it is not so much more work and if i have some time left, i will try to complete the solution with the rasterization of the polygons themselves.

I already stumbled upon the vtkImplicitModeller, but to be honest, from the class documentation alone i didn't completely "get" what it is really doing, e.g. what is the "output" of it.

Does it compute a distance field where the cell values of the grid contain the distances from the cell to the isosurface?

Something like:

delta is a constant which determines how far from the edge of the letter the anti-aliasing extends. The actual shader code I use in bulldog is slightly more complex as it handles borders and reversed characters (such as when selecting text in a textbox), as well as adjusting the anti-aliasing for different font sizes.

Hi David,


Is there some way with the available vtk filters to rasterize the polygons themselves instead of rasterizing the volume enclosed by the polygons?

That's what vtkImplicitModeller does, so you could combine its results with the results that you already have.


I know, i could in some way misuse the vtk renderer to do this by rendering the mesh without any shading, only in ambient, completely white with orthogonal projection etc. in a black render window, sized to the voxel resolution, then read the resulting screen pixels with the vtkWindowToImage Filter, fill the vtkImageData where i have white pixels, change the clipping planes to the next slice, draw the mesh again, read again ... and do that slice by slice for the depth part of the voxel resolution:

This won't work for polygons that face the camera edge-on, since they are invisible in the rendering.  So you would have to do it from three directions and then combine the results.  Even then, I'm not sure how good the quality would be.

It computes unsigned distance.  No, it doesn't compute distance from an
isosurface: it computes the distance to the actual polygon, which is a
vectorized (not yet rasterized) object. All that remains to be done is
binarization via thresholding.

Hi David,


thanks again.


I am sorry, i don't want to get on your nerves. I know that all of you have a lot of work to do yourselves and i am thankful for every effort everybody takes on this mailing list in helping others and especially for your support in my problem.


You are right in that since vtk is an open source project everybody can look at the code if the documentation alone is not clear enough to them.


But as a vtk beginner, what i found out though is, that the amount of comments in the vtk filter classes vary a lot. While some classes are self explanatory, greatly commented and have some example code in the github repository others can require more research.


Then some of the classes are self-contained where reading the source code of the class alone is enough, others depend on a lot of other vtk classes and you have to read through nearly all of them or at least the corresponding class documentation to get to know what is going on which can take a long time.


So your explanation that it computes an unsigned distance to the actual polygon is completely to the point and is all what i wanted to know and saved me a lot of time.



Cheers,


Berti

Hi Berti,

I just wanted to make it clear that I'm only closely familiar with a small
fraction of the VTK classes... when I do anything in VTK that involves
unfamiliar classes, of course I also have to delve into the documentation
and often into the code.  The vtkImplicitModeller falls into "unfamiliar"
territory for me: I'm vaguely aware of what it does, but I've never used it
and I'm hardly an expert on it.

Subject: [vtkusers] Problem coloring actor
Message-ID: <CAKuw5X31ROG0LY9yaZd5pCOQUGugLC+wtSAydOPgPZxJ5Qz3=g@mail.gmail.com>

Dear All,

I am using vtk7.1 in my project. I am trying to color the actor using the
below code, while it works for some colors other are rendered as white or
in something else. The same code used to work well in vtk6.

Does ambient, diffuse, etc... has any effect? I tried setting the color in
[0,1] and [0,255] format and no change in behavior.

Any suggestions?

 // Create plane actor

    vtkSmartPointer<vtkActor>cutROI=

            vtkSmartPointer<vtkActor>::New();

    //qDebug()<<R<<G<<B<<"RGB...";

    //unsigned char color1[3] = {255, 180, 255};

    cutROI->GetProperty()->SetColor(255.0,180,255.0);

    cutROI->SetMapper(cutterMapper);

    cutROI->GetProperty()->SetAmbient(1.0);

    cutROI->GetProperty()->SetDiffuse(0.5);

    cutROI->GetProperty()->SetSpecular(0.0);

    cutROI->GetProperty()->SetOpacity(0.95);

    cutROI->GetProperty()->EdgeVisibilityOff();

    //cutROI->GetProperty()->SetEdgeColor(R,G,B);

    cutROI->GetProperty()->SetLineWidth(1.5);

Thanks

Ia m using Mesa software based rendering rather than hardware based one
since I don't have  graphics card on my server.

Hi,

QVTKOpenGLWidget do support HighDpi.

Just a small warning about QVTKOpenGLNativeWidget (the one you need to
use if you require a native widget): It will not properly support
fractional device pixel ratios (e.g. 150% or 250%), only integer ones
(100%, 200%, ...).

I have an old MR here to fix this:
https://gitlab.kitware.com/vtk/vtk/merge_requests/3973 . It's been on
my TODO to update this MR after the new QVTKOpenGLWidget was merged
and the old one was renamed to QVTKOpenGLNativeWidget, but work has
just kept me so busy that I haven't found time for it.

Hi Folks,

My apology for answering late, I was literally our of town without any
connection for the past two weeks and didn't have a chance to comment
earlier.

While 3D Slicer itself can easily be updated, there are projects that build
against 3D Slicer and/or dependent on 3D Slicer while supporting being
built against different of VTK. To avoid the burden of updating each one of
these projects, I am writing an email to the list to check if others would
support reverting back to version 9.0.0 ?

Thanks
Jc

Subject: [vtkusers] smoothen binarized vtkImageData
Message-ID: <1538561858096-0.post@n5.nabble.com>

I want to smoothen binarized vtkImageData like image below from right to left
<http://vtk.1045678.n5.nabble.com/file/t281986/123132.png> 

I followed
https://stackoverflow.com/questions/45365727/vtk-volume-visualization-issue
and had results like below
<http://vtk.1045678.n5.nabble.com/file/t281986/22222.png> 

Then I tried using linear interpolation, the colors turned to be abnormal

<http://vtk.1045678.n5.nabble.com/file/t281986/33333.png> 

Below are my code pieces:

//Declaring Variables
	vtkSmartPointer<vtkVolumeProperty> volumeProperty;
	vtkSmartPointer<vtkPiecewiseFunction> compositeOpacity;
	vtkSmartPointer<vtkColorTransferFunction> color;
	vtkSmartPointer<vtkVolume> volume;
	vtkGPUVolumeRayCastMapper* mapper = vtkGPUVolumeRayCastMapper::New();
	
	volumeProperty = vtkSmartPointer<vtkVolumeProperty>::New();
	compositeOpacity = vtkSmartPointer<vtkPiecewiseFunction>::New();
	color = vtkSmartPointer<vtkColorTransferFunction>::New();
	volume = vtkSmartPointer<vtkVolume>::New();

	mapper->SetAutoAdjustSampleDistances(0);
	
	double spacing[3];
	m_RegionImageData->GetSpacing(spacing);
	

	double distance = spacing[0];
	if (distance>spacing[1])
	{
		distance = spacing[1];
	}
	if (distance>spacing[2])
	{
		distance = spacing[2];
	}
	distance = distance / 2.0;



	mapper->SetSampleDistance(static_cast<float>(distance));
	volumeProperty->ShadeOn();
	volumeProperty->SetIndependentComponents(1);
	volumeProperty->SetInterpolationTypeToLinear();
	volumeProperty->SetColor(color);
	volumeProperty->SetScalarOpacity(compositeOpacity);
    mapper->SetBlendModeToComposite();
	m_RegionImageData->UpdateCellGhostArrayCache();
	mapper->SetInputData(m_ReigonGrowing->m_RegionImageData);
	mapper->SetMaskTypeToLabelMap();
	mapper->SetMaskBlendFactor(0.8);
	volume->SetMapper(mapper);
	volume->SetProperty(volumeProperty);
	m_cImage3DViewer->getRenderer()->AddViewProp(volume);
	//Setting Voxel Data and Its Properties
	compositeOpacity->AddPoint(0, 0);
	for (int i = 1; i <
m_ReigonGrowing->m_lookupTable->GetNumberOfTableValues(); i++)
	{
	
		compositeOpacity->AddPoint(i, 1);
		color->AddRGBPoint(i, m_ReigonGrowing->m_lookupTable->GetTableValue(i)[0],
m_ReigonGrowing->m_lookupTable->GetTableValue(i)[1],
m_ReigonGrowing->m_lookupTable->GetTableValue(i)[2]);
	}

	m_cImage3DViewer->getRenderer()->ResetCamera();
	

/*m_cImage3DViewer->assignImageToVolume(m_pProjectData->GetActivePatientData()->GetOriginImageDataPtr(),
m_cImage3DViewer->m_k3DLUT);
	
	StartAdjustCropRegionWidget();*/

m_cImage3DViewer->getRenderer()->GetRenderWindow()->GetInteractor()->Render();

Does anyone has any ways to smoothen binarized vtkImageData?

To interpolate a discrete segmentation you must use nearest neighbor
interpolation.

Hi Bill,

thanks for your help,


In your case, you did convert vtkImageData to vtkPolyData and use
vtkWindowedSincPolyDataFilter to smooth vtkpolyData.

If I don?t want to convert vtkImageData to vtkPolyData , can I obtain smooth
result in 3D view using vtkImageData?

While it might be tempting to hook into the templated vtkDataArray
subclasses 'vtkAOSDataArrayTemplate' or 'vtkSOADataArrayTemplate', this
will likely cause headaches as these ValueTypes expect to be implicitly
convertible to/from double.

Your best option here would be to write your own subclass of
vtkAbstractArray (the superclass of vtkDataArray), since that has much less
stringent requirements and is already used for things like strings, etc.
See vtkStringArray for an example subclass that doesn't just hold a trivial
numeric type.

Allie

Message-ID: <1047b72226116c14c1660cf45b54fb65@dornheim-medical-images.com>

Hey Guys,
Has anyone of you been able to use the vtkOpenVR classes on Linux?
I can run Steam with SteamVR on a Ubuntu 18.04 system, but when I try to run the HelloWorld Example of VTK modified for VR, I encounter a segmentation fault.
You can find the code I used here: https://pastebin.com/gjsvKy58 (https://pastebin.com/gjsvKy58)
The whole project with binary and core dump can be found here: https://transfer.sh/6vONY/build.zip (https://transfer.sh/6vONY/build.zip)

Do you have any suggestions on how to get this working?

Thanks in advance!

Best regards,
Max.Deubel

You need to create an use an OpenVRCamera. From your code it doesn't look
like you are. I doubt that is the crash but it could be.

Does the example work on windows? Since linux is an unknown I would think
it would be best to make sure you have something working on windows, then
port to linux.

Subject: [vtkusers] Qt, vtkImageView2, image and mask
Message-ID: <62ED5F8C-8E62-4B22-ACB4-7222C190E389@gmail.com>

Hello everyone,

I try to add a mask to a 3D image (dicom) with no success.

I followed this example:
https://cmake.org/Wiki/VTK/Examples/Cxx/Images/Transparency

This is the step I follow:

// Load the dicom
vtkSmartPointer<vtkImageData> image = loadDicom(filename);
imageViewer2D->SetInputData(image);
imageViewer2D->GetRenderer()->ResetCamera();
imageViewer2D->Render();

// In a second time

// Load the mask (with the same dimension, origin, spacing as the dicom image
vtkSmartPointer<vtkImageData> maskImage = loadMask(filename_mask);

vtkSmartPointer<vtkLookupTable> lookupTable =
					vtkSmartPointer<vtkLookupTable>::New();
lookupTable->SetNumberOfTableValues(3);
lookupTable->SetRange(0.0,2.0);
lookupTable->SetTableValue( 0, 0.0, 0.0, 0.0, 0.0 ); //label 0 is transparent
lookupTable->SetTableValue( 1, 1.0, 0.0, 0.0, 1.0 ); //label 1 is opaque and red
lookupTable->Build();

vtkSmartPointer<vtkImageMapToColors> mapTransparency = vtkSmartPointer<vtkImageMapToColors>::New();
mapTransparency->SetLookupTable(lookupTable);
mapTransparency->PassAlphaToOutputOn();
mapTransparency->SetInputData(maskImage);
mapTransparency->Update();

vtkSmartPointer<vtkImageActor> maskActor = vtkSmartPointer<vtkImageActor>::New();
maskActor->GetMapper()->SetInputConnection(mapTransparency->GetOutputPort());
maskActor->Update();

imageViewer2D->GetRenderer()->AddActor(maskActor);
imageViewer2D->GetRenderer()->ResetCamera();
imageViewer2D->Render();



When I load my mask and add it using vtkImageViewer2D::SetInputData method, I see correctly my mask.

Is it possible that the image is in first plane and not the mask is hidden by it? If it?s the case, how can I change this behavior?

Thank you,

Romain

Subject: [vtkusers] Picking an Actor only works with TrackballCamera?
Message-ID: <1538677455302-0.post@n5.nabble.com>

Hello guys,

I'm trying to implement the picking mechanic in my project and the examples
worked perfectly fine for me. Now I have problems when trying to implement
the example (under CXX/Interaction/Picking) in my project.

When I derive a class (so I can override OnLeftButtonDown) from
vtkInteractorStyleTrackballCamera, like in the examples, it works in my
project, but if I derive it from vtkInteractorStyleSwitch then the mouse
event doesn't work. The OnLeftButtonDown just won't get called and I don't
get why.

I need the vtkInteractorStyleSwitch since I want the user to be able to
switch styles.

I hope someone can help.
Thanks in advance!

Andras,


As you said , using vtkflyingEdge3DFilter and vtkWindowedSincPolyDataFilter
take much time to compute and I evaluate segmentation  result by using
volume rendering for displaying in  real time.


Could you share your code?

thanks.

All of our source code is publicly available: https://github.com/Slicer/Slicer

More specifically:
- Slice and 3D visualization of overlapping segments: https://github.com/Slicer/Slicer/tree/master/Modules/Loadable/Segmentations/MRMLDM
- Conversion between different representations (binary labelmap, closed surface, fractional labelmap): https://github.com/Slicer/Slicer/tree/master/Libs/vtkSegmentationCore

You can take any code you find useful, there is no restriction of using the code or the entire application for any purpose. As you can see, there has been a lot of work put into this and it is constantly improved, so instead of re-developing segmentation tools from scratch (and keep maintaining and improving them), you can build your tools based on 3D Slicer and sit back and let others develop, test, maintain, optimize the underlying infrastructure.

Subject: [vtkusers] Adding and coloring data to a vtkLineSource

Hi,

vtkLineSource creates a polyline with n points. Consequently, it
outputs a single cell and the computed cell data contains just one
value and you cannot get the colormap for this. Since there are
multiple points, the point data should be used in stead of the cell
data.

Subject: [vtkusers] Qt, vtkImageView2, image and mask
In-Reply-To: <62ED5F8C-8E62-4B22-ACB4-7222C190E389@gmail.com>

Hi Romain,

The vtkImageViewer2 is only designed for one image, so adding another
vtkImageActor to it will usually not give good results.  Your guess that it
is not showing the same slice is probably correct, but even if it did show
the same slice, the mask might be invisible if it is rendered first instead
of last.

Since your mask is the same size as the image, you can use vtkImageBlend to
combine them into a single image for vtkImageViewer2.  To do this, the
DICOM image would have to go through vtkImageMapToColors to convert it from
grayscale to RGB or RGBA, then the RGBA mask can be added with
vtkImageBlend.

The other option is to create your own vtkRenderWindow instead of using
vtkImageViewer2.  This will give you more flexibility in terms of what you
add to the window and how you interact with it.  For example, see the
following example:
https://github.com/Kitware/VTK/blob/9ac8f74/Examples/ImageProcessing/Python/ImageInteractorReslice.py

Also, in for your mask lookup table you have SetNumberOfTableValues(3) and
SetRange(0,2).  I'm guessing that these were just experimental values,
since a mask should use SetNumberOfTableValues(2) and SetRange(0,1).

Cheers,
 - David

Subject: [vtkusers] vtk.js How to read my *.vti file using
 vtkHttpDataSetReader?
Message-ID: <1538778124656-0.post@n5.nabble.com>

I have uploaded a volume data *.vti file to my server and setting up the URL
reader.setUrl(`http://xyz.com/files/test.vti`). It never loaded in my
application? But when I set a URL from vtk.js samples it works fine. I
observed there is a index.json file that needs to be loaded but couldn't get
what's that and where to put in my website? Is there any documentation on
index.json file? Or any reference or utility to create my own data file
compatible to vtk.js loaders?

Thanks.

In the example for the HttpDataSetReader we have the following comment:

*Caution*: The example is not actually loading a vtp file but a data
structure that was coming from a vtp file. For more details please
read the vtkHttpDataSetReader
API <https://kitware.github.io/vtk-js/api/IO_Core_HttpDataSetReader.html>;

For your file format, you want to use that following reader:

Thanks for the answer. 
That's where I got confused. Did several tests to load but never worked. 
I have already checked these links and try to follow but couldn't get file
loaded.
So, you mean I have to manual create an index.json metadata file that should
contain *.vti file information? Actually, I am interested to load the file
from the internet (urlfile), not from the local disk, so that's why I guess
I have to use HttpDataSetReader?

Glad that you figure it out.

The HttpDataSet reader was created to load some pre-processed dataset
before we had any reader that could understand vtki/vtp format.
We use that script [1] with ParaView to load any dataset and convert into
that json + binary format that was easy to load in JavaScript over http.
It is still an interesting format as it is well designed for dataset over
the network when you don't want/need to load everything right away.

Subject: [vtkusers] Light follow camera in QVTKWidget and OpenGL 1/2 build
Message-ID: <1538814784169-0.post@n5.nabble.com>

Hello! I use QVTKWidget to render 3D object and take it 2D projections with
different light params and positions. Only standard headlight is used. VTK
build with OpenGL1 work fine, but in OpenGL2 I cant disable light follow
camera:
    Interactor->SetLightFollowCamera(false);
    Renderer->SetLightFollowCamera(false); //disable light follow camera in
OpenGL1, but not OpenGL2
What would you recommend doing?
Use manually created light and on/off following light by camera observer?
vtkLightKit?

PS. I know that QVTKWidget is deprecated, but it provide simplest way to
change OpenGL 1/2 build type. Or I'm wrong, is there an easier way?

Rasoul,

What kind of data do you expect as a result of the segmentation? If it is
polygonal data, you can use vtkPolyDataMapper for the segmentation. If it
is volumetric, you can use the vtkGPUVolumeRayCastMapper.

As for the MPR view, take a look at vtkImageActor (or
vtkImageResliceMapper, if you expect oblique slices).

Take a look at VTK examples for setting up pipelines for MPR and volume
rendering.
As for showing them in the same window, you just have to make sure that all
the actors/props should be added to the same renderer.

Hope that helps.

Subject: [vtkusers] Correct use of vtkClipVolume in volume rendering?
Message-ID: <1539072589362-0.post@n5.nabble.com>

Hi everyone,

It is indeed a basic question but I've striven to find any example or
explanation in the mailing list or forum or stack overflow concerning this. 

I have a .mhd file that I render in volume following the medical volume
rendering example.

I'd like to implement volume exploration for this, so I think about using a
plane (then spheres etc.) to clip the volume. 
But my following code has no effect, and I guess I need to use
vtkClipVolume, but there zero information about how to use it in the
documentation.

  Code :
//Plane clipping 
vtkSmartPointer<vtkPlane> cuttingPlane = 
  vtkSmartPointer<vtkPlane>::New();
cuttingPlane->SetOrigin(0, 0, 0);

volumeMapper->AddClippingPlane(cuttingPlane);


Thank you very much for your help, 
I find learning VTK is drastically slowed down because of missing
information.
Severin

Dear Ken,
I finally managed to get my code building and running on both Windows and Linux.
You can find it here:
https://transfer.sh/gJ1Sg/vtkOpenVRHelloWorld.zip (https://transfer.sh/gJ1Sg/vtkOpenVRHelloWorld.zip)

Unfortunately, it doesn't work with the latest VTK-Version from https://gitlab.kitware.com/vtk/vtk (https://gitlab.kitware.com/vtk/vtk)
After some testing, I found the first commit it doesn't build with: https://gitlab.kitware.com/vtk/vtk/commit/61bc6b5b4b8f0d2d111f6c10af3dd79488f919cc (https://gitlab.kitware.com/vtk/vtk/commit/61bc6b5b4b8f0d2d111f6c10af3dd79488f919cc)
(VTK builds, but my program doesn't build with this VTK Version)

Even though I already use the vtkOpenVR* classes explicitly, it doesn't build.
Is there something else I have to change to make it compatible?

Make produces the following Linker error:

[ 50%] Linking CXX executable vtkOpenVRHelloWorld
CMakeFiles/vtkOpenVRHelloWorld.dir/CylinderRenderingProperties.cxx.o: In function `vtkRenderingOpenGL2_AutoInit::vtkRenderingOpenGL2_AutoInit()':

Any help would be appreciated!

Best regards,
Max.D.

Does the example work on windows? Since linux is an unknown I would think it would be best to make sure you have something working on windows, then port to linux.

Hey Guys,
Has anyone of you been able to use the vtkOpenVR classes on Linux?
I can run Steam with SteamVR on a Ubuntu 18.04 system, but when I try to run the HelloWorld Example of VTK modified for VR, I encounter a segmentation fault.
You can find the code I used here: https://pastebin.com/gjsvKy58 (https://pastebin.com/gjsvKy58)
The whole project with binary and core dump can be found here: https://transfer.sh/6vONY/build.zip (https://transfer.sh/6vONY/build.zip)

Do you have any suggestions on how to get this working?

Thanks in advance!

You have to explicitly instantiate the OpenVR classes. Basically change

  vtkNew<vtkRenderWindow> renderWindow;

to

vtkNew<vtkOpenVRRenderWindow> renderWindow;

for renderwindow, renderer, interactor and camera.  Give that a shot.

Thanks!
Ken

Great!

Once you?ve loaded the volume into a vtkImageData, you could use
vtkFlyingEdges3D to create isosurfaces from the volume.

Please keep replies on the list for the benefit of other users.

Thanks,

You may need

#include "vtkAutoInit.h"
VTK_MODULE_INIT(vtkRenderingOpenGL2)
VTK_MODULE_INIT(vtkRenderingOpenVR)


or similar.  Give that a shot - Ken

Resurrecting this - I cannot even get it to work in inverse mode, it only
keeps the points, not the cells. I have tried using vtkExtractSelection and
vtkExtractSelectedIds, but neither will extract the cells. Any idea what I
am missing here?

                        std::cout << "Removing " <<
ids_for_removal->GetNumberOfTuples() << " points on boundary" << std::endl;
			// Run the extraction filter (inverted)
			vtkSmartPointer<vtkSelectionNode> selectionNode =
vtkSmartPointer<vtkSelectionNode>::New();
			selectionNode->SetFieldType(vtkSelectionNode::POINT);
			selectionNode->SetContentType(vtkSelectionNode::INDICES);
			selectionNode->SetSelectionList(ids_for_removal);
			selectionNode->GetProperties()->Set(vtkSelectionNode::INVERSE(), 1);
//invert the selection so we extract everything NOT labelled
			selectionNode->GetProperties()->Set(vtkSelectionNode::CONTAINING_CELLS(),
1);
			
			vtkSmartPointer<vtkSelection> selection =
vtkSmartPointer<vtkSelection>::New();
			selection->AddNode(selectionNode);

			vtkSmartPointer<vtkExtractSelectedIds> extractSelectedIds =
vtkSmartPointer<vtkExtractSelectedIds>::New();
			extractSelectedIds->SetInputData(0, mesh_in_out);
			extractSelectedIds->SetInputData(1, selection);
			extractSelectedIds->Update();

			// Back up the data
			vtkSmartPointer<vtkPolyData> temp2 = vtkSmartPointer<vtkPolyData>::New();
			temp2->DeepCopy(extractSelectedIds->GetOutput());
			std::cout << "Before mesh has : " << mesh_in_out->GetNumberOfCells() << "
cells and " << mesh_in_out->GetNumberOfPoints() << " points" << std::endl;

			std::cout << "Extracted mesh has : " << temp2->GetNumberOfCells() << "
cells and " << temp2->GetNumberOfPoints() << " points" << std::endl;


My output is :

Removing 216 points on boundary
Before mesh has : 125688 cells and 62941 points
Extracted mesh has : 0 cells and 62725 points

Maybe try something like the following in your CMakeLists. It works for me
without adding any autoinit stuff.

find_package(VTK REQUIRED)
vtk_module_config(VTK
  vtkCommonCore
  vtkCommonDataModel
  vtkFiltersGeneral
  vtkIOImage
  vtkIOXML
  vtkInteractionStyle
  vtkRenderingOpenGL2
  vtkRenderingOpenVR
)
include(${VTK_USE_FILE})

Subject: [vtkusers] Color a contour from a Niftii image
Message-ID: <1539139292633-0.post@n5.nabble.com>

Hello,

I am trying to generate a visualization of a contour of a Niftii file, but
with colors interpolated from that same image, not a monochrome
representation. The resulting image shows the color variation, but it does
not use the colors I set in my lookup table. Do you know why this could be
happening? I wonder if it is because of the interpolation affecting not only
hue, but also saturation and value parameters.

My code is below.

NiftiReader = vtk.vtkNIFTIImageReader()  

ren = vtk.vtkRenderer()
ren.SetBackground(0, 0, 0)
renWin = vtk.vtkRenderWindow()
renWin.SetSize(800, 600)
renWin.AddRenderer(ren)
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)
iren.SetInteractorStyle(vtk.vtkInteractorStyleTrackballCamera())

surface = vtk.vtkContourFilter()
surface.SetInputConnection(NiftiReader.GetOutputPort())
surface.SetValue(0,300)

#Colors
lut = vtk.vtkLookupTable()
lut.SetNumberOfColors(256)
lut.SetTableRange(400, 905)
lut.SetHueRange(0.0, 0.75)
lut.SetSaturationRange(1.0, 1.0)
lut.SetValueRange(1.0, 1.0)
lut.Build()

#Map to colors
mapToC = vtk.vtkImageMapToColors()
mapToC.PassAlphaToOutputOn()
mapToC.SetLookupTable(lut)
mapToC.SetInputConnection(NiftiReader.GetOutputPort()) 
#mapToC.SetOutputFormatToLuminance()
mapToC.Update()

#Probe
probe = vtk.vtkProbeFilter()
probe.SetInputConnection(surface.GetOutputPort())
probe.SetSourceConnection(mapToC.GetOutputPort())
probe.Update()

# Create a mapper and an actor for the extracted surface
smapper = vtk.vtkPolyDataMapper()
smapper.SetInputConnection(probe.GetOutputPort())
#smapper.ScalarVisibilityOn()
#smapper.SetLookupTable(lut)
#smapper.SetScalarRange(400, 905)
#smapper.SetScalarModeToUseCellData() 

actor = vtk.vtkActor()
actor.SetMapper(smapper)
ren.AddActor(actor)

iren.Initialize()
renWin.Render()
iren.Start()

The code that you shared extracts an isosurface at intensity value of 300, which means that all the voxels at the surface have this same intensity value. No matter what lookup table you specify because all point scalars retrieved by probe filter will have the value of 300.

If I understand correctly, you would like to extract a colored model from a volume, without segmentation - similarly to how a volume rendered image would look like, just with surface models. The issue is that this is not possible - see detailed discussion here: https://discourse.slicer.org/t/save-volume-rendering-as-stl-file/524. If the goal is to 3D print  volume rendering in then you can do it with special 3D printers as described here (not from surface meshes): https://discourse.slicer.org/t/printing-volume-renderings-in-plastic/3017.

Subject: [vtkusers] Multiplanar reconstruction(MPR) for MR
Message-ID: <CAPPKgL3_SxxjAzvfR0ZDxSVacCv1CFcaYtjVO0tQiBL-8QcC6g@mail.gmail.com>

Hey Guys,

I'm facing problem in creating MPR for particular MR data set which is
having image orientation:

*0.08153987675905\0.77476596832275\0.62696808576583\0.03836457058787\0.62615668773651\-0.7787528038024*

By using this orientation how can i able to find out in which plane the MR
data has been acquired. whether it is Axial/Sagittal / Coronal?

Is there any class in VTK which gives this output.

PFA Image1 is the output i'm getting and Image2 is the expected output.

Subject: [vtkusers] VTK compilation with ExternalRendering
Message-ID: <1539161249299-0.post@n5.nabble.com>

Hi Everyone,

I woud try to use the vtkExternalOpenGLCamera to set my own view and
projection matrices. So after a git clone, I have tried to compile the last
version of the master branch with Visual Studio 14. The compilation failed
due to line 130:
if ((ren->GetRenderWindow())->GetErase() && ren->GetErase() &&
!ren->GetIsPicking() )
-> vtkRenderer has no GetIsPicking member.
If I comment this last part, everything compiles well but maybe it's not a
good solution to remove this last test. What do you think?
Best Regards

Sophie

Hello community,

We sometimes get an ugly crash in our app, for the first rendering on a 3D

We are using QT 5.9.4, and VTK 8.1.

Here is the stacktrace, does that ring a bell to anyone ?

You will need to set the volume property, e.g.:

Subject: [vtkusers] using vtkLandmarkTransform to align two nii volumes
Message-ID: <CALbMNizhx=kAau7xFKt3wt71pzGhtJJg1Jti+LZgVc+tAKnhvQ@mail.gmail.com>

Hi VTK experts,
   I am trying to using vtkLandmarkTransform  to align two nii volumes and
am getting puzzling results. I identify the landmarks in the two 3D volumes
by visualizing the volumes in VTK and using the GetPickPosition method. The
coordinates I get are in units of mm with the origin being one corner of 3D
volume.
    I then use vtkLandmarkTransform to get an affine transformation to
align the points. The points align great, but when I apply that same
transform to the analogous nii volume via vtkImageReslice, the results are
wildly off (e.g., the volume is flipped upside down).
   Is the qform matrix of each nii file somehow causing this? Do I need to
first apply the qform matrix to the landmark points to get them in scanner
coordinates before using vtkLandmarkTransform?
       thank you for any advice you can provide,
            -Ms. Merps

Thank you for your answer. To simplify the analysis of correctness, I created
a test image. Added volume property code:

vtkNew <vtkVolumeProperty> volumeProperty;
volumeProperty->SetInterpolationTypeToLinear();
volumeProperty-> ShadeOn ();

v-> SetMapper (volumeMapper);
v-> SetProperty (volumeProperty);

However, this solution did not help correctly display the loaded image. I
also tried to set the parameters Ambient, Diffuse, Specular. I attach the
original object and the result of the visualization.

<http://vtk.1045678.n5.nabble.com/file/t342584/test.png> 
<http://vtk.1045678.n5.nabble.com/file/t342584/test_result.png> 

Maybe tell me what could I miss? On the original image, different levels of
brightness of the object are clearly visible, while rendering the brightness
is completely different.

The property needs a color transfer function and an opacity transfer function.
Please read all the comments in the example, the comments will answer
most of your questions. There is also a description of the volume rendering
process in the VTK textbook:

https://lorensen.github.io/VTKExamples/site/VTKBook/07Chapter7/#77-volume-classification

To keep things simple at first, you can use ShadeOff() and you can ignore
the gradient opacity function.  But the color transfer function and the opacity
transfer function are always required.

Subject: [vtkusers] slicing ploydata with plane
Message-ID: <CAJZDnTiotAQLcgmYi3qwmyvLVb9oO4o=1GBHCHidLC0-PgWZiw@mail.gmail.com>

dear all,

I am displaying a volume with an interactor style  vtkInteractorStyleImage
. That means I'm looking at slices.

I'm overlaying a group of points in space as a polydata. The expected
behaviour would be to be able to see the points which are in the current
slice. The slice is updated by a MouseWheelForwardEvent and
MouseWheelBackwardEvent.

I attach a small drawing to clarify.
1) the drawing depicts a side view (say XZ). The camera is looking from the
top on the XY plane
2) the points I am talking about are the circles connected with line.
3) the slice I'm showing is 1 voxel thick, is colored in red and is at
Z_slice
4) in red are also the points I expect to see

If I display the polydata as is, I will see every point whose Z >= Z_slice,
as the one below the slice will be hidden by it. Therefore:

1) I use a vtkClipPolyData with a plane implicit function.
2) I added an observer to update the plane position on mouse wheel
back/forward events.
3) I attached the observers to the same callback.
4) the callback puts the plane at Z_slice


While the MouseWheelBackwardEvent works fine, the MouseWheelForwardEvent
does what I expect only if I shift the plane of +2 voxels in Z.

Do you have any explanation on why should I add that +2 voxel shift?

Thanks

Edo

Hi,
I'd dare to say that the short answer is yes.

Long answer is that VTK deals with world coordinates, and according to
the right hand rule. NIfTI uses RAS convention. According to the
vtkNIFTIImageReader::GetQFormMatrix documentation, NIfTI does not
ensure that coordinates are stored following that convention, so you
should definitely use the matrix given.

The following Slicer 3D wiki page and David Gobbi's document be
helpful to this end:
https://www.slicer.org/wiki/Coordinate_systems
http://calgaryimageanalysis.ca/wiki/images/5/52/Image-orientation.pdf

May be David himself can chime in and be able to provide a better or
cleaner explanation.

HTH,
JON HAITZ

Hi Jon,

The vtkNIFTIImageReader ensures that the vtkImageData that it produces
follows the right-hand-rule, even if the slices were ordered in
reverse in the NIFTI file itself. As the documentation states:

  ...if QFac is -1, then the first slice in the VTK image data is the
last slice in the NIFTI file...

All the details of qfac are documented in the nifti header file:
https://nifti.nimh.nih.gov/pub/dist/src/niftilib/nifti1.h

Use of the qform in VTK is optional.  Use it if you want to work in
RAS coordinates.  But often it is both simpler and more appropriate to
work in VTK data coordinates instead, and to me it sounds like this is
the case for the original question.  In any case, vtkImageReslice uses
VTK data coordinates (not VTK world coordinates, nor RAS coordinates).

I know this isn't a very clear explanation, but unfortunately it's all
I have time for (and all that my brain is capable of right now, given
the tiny amount of sleep I've had over the past few days).

Thanks very much for the speedy help, David & Jon.
Applying the inverse of the landmark transform derived from the points
solved the problem.
I still don't understand why for polydata you apply the landmark transform
and for image data you apply the inverse, but that's Ok for now.

I also want to write the transformed nii volume to file. In addition to
using SetInformationInput to set the transformed nii volume's spacing,
origin, and extent, is there any other information I should be modifying in
the transformed Nii's header?
   thank you again,
      -M

For writing a nifti file after registration, it's very important to
set the sform and qform for the writer to the sform and qform of the
reference image (I.e. _not_ the qform, sform of the image that was
resliced!)

writer->SetSFormMatrix(referenceReader->GetSFormMatrix());
writer->SetQFormMatrix(referenceReader->GetQFormMatrix());
if (referenceReader->GetQFac() < 1) {
    writer->SetQFac(-1.0);
}

The QFac setting ensures that the slices are written in the same order
as the reference image.

It's possible to copy other parts of the header, too, but you have to
be careful when you do so, since some parts of the header relate to
the reference image, other parts of the header relate to the image
that was resliced, and some parts relate to neither.  Just copying the
qform and sform is usually sufficient.

I made a typo in the code in my last reply.  It should be:

if (referenceReader->GetQFac() < 0.0) {
    writer->SetQFac(-1.0);
}

Subject: [vtkusers] Drawing custom image with depth buffer and a translucent
 plane
Message-ID: <4A2A9A281AE5D54CA205FB13069FD874017ACEF22D@US01WEMBX2.internal.synopsys.com>

Hi Everyone,

I'm trying to draw a vtkVolume and a vtkPlaneWidget both intersecting and the vtkPlaneWidget is translucent. I cannot achieve that, either the plane is totally behind or front.

For a vtkActor with the same box extent this works.

I tried to get the z-buffer from the context using vtkRenderer::GetZbufferData() method, but I only get 1s. (Is this correct?)
I also tried to write the z-buffer data I got with vtkRenderer::SetZbuferData() method, but the plane is still behind.

Any hints how to achieve this? Thanks in advance.

Subject: [vtkusers] Alternative to vtkDelaunay2D for surface reconstruction
 or how to get rid of "Edge not recovered, polygon fill suspect"
Message-ID: <HE1PR0801MB20734DF6515DAF5BF13A4C4981FC0@HE1PR0801MB2073.eurprd08.prod.outlook.com>

Hello everyone.

In my project i have a standard 3D triangle mesh surface where i select all vertices which lie inside a region (polygon) which is defined by a closed polyline created by an user interaction using the vtkContourWidget:

[cid:inline_01 at geary]

I then create a polygon mesh which has the shape of the vtkContourWidget polygon selection contour line plus the selected part of the underlying mesh and which lies like a sticker or texture on the the given stl mesh surface:

[cid:inline_00 at geary]

For the reconstruction of the surface i use the vtkDelaunay2D filter using all the points of the vtkContourWidget polygon and the mesh surface points as inputs.

This works absolutely great but depending on the used mesh i sometimes get the following error message from the vtkDelaunay2D filter:

"vtkDelaunay2D (0x556183dcfba0): Edge not recovered, polygon fill suspect"


Does anybody know why this happens and what i can do to get rid of this error?

While nice, but since i don't necessarily need the delaunay properties, is there an alternative to the vtkDelaunay2D filter to get a polygon surface mesh given a bunch of points as an input? (points -> surface)


Thank you very much in advance.

Regards,
Berti

Subject: [vtkusers] CMake custom class python wrapping doesn't work

Hello.
I have a common wrapping that previously worked on windows 8.1 with

Hi Evgeniya,

Based on my understanding, wrapping of custom classes without (1) creating
an external VTK module or (2) using the VTK build system (like Paraview
does) is not supported.

If possible, I suggest you re-organize your code to create a VTK external
module. That you will be able to use the VTK CMake API by including the
vtkExternalmoduleMacros.
For example, see
https://github.com/Kitware/VTK/blob/master/Rendering/OpenVR/CMakeLists.txt
(while this module can be built both as a built-in module and an external
module, it illustrates the idea)



If not possible, you need to make sure the python hierarchy files are
generated.
Here is a module we maintain in Slicer that enable this. It provides a
macro named "vtkMacroKitPythonWrap"
See
https://github.com/Slicer/Slicer/blob/master/CMake/vtkMacroKitPythonWrap.cmake

Here is an example of usage:

 include(vtkMacroKitPythonWrap)

  vtkMacroKitPythonWrap(
    KIT_NAME vtkFoo
    KIT_SRCS ${vtkFoo_SRCS}
  )

Subject: [vtkusers] A bug in Above/BelowRangeColor mapping?
Message-ID: <7917862a-e659-cc50-597b-058c752d2206@gmail.com>

Hi,

I think the behavior of UseBelowRangeColor in both VTK 8.1.1, and 
Parview 5.5 is wrong. As an example, I load a surface into Paraview, 
rescale the color range to point data (elevation in this case, fig. 
paraview.png), and enable the 'Use Below Range Color' checkbox. What you 
see is that part of the surface are colored with black (fig. 
paraview_wrong.png), although they are in fact within the automatically 
computed value range. So they should get the usual color from the lookup 
table.

I also observe wrong behavior when I color the surface by a constant 
value. In VTK, I set lower/upper bound on data values in vtkLookupTable 
to be the same. Say, my point data has value 50. I set the lookup table 
range to [60,60] and turn on Above/Below range color. Figure 
constant_wrong.png shows that my surface is colored with the in-range 
color, although it is below range. To get a correct coloring I need to 
spread the range a little bit, e.g., [60,61] (constant_below.png), or 
[40, 41] (constant_above.png). But even in this case we go back to the 
first problem: for point values that are on the edge of the range VTK 
uses out-of-range color (range [50,51], constant_extreme.png).

So the question is - is this behavior intended, and if so - how should I 
organize my color mapping and data ranges to get the expected behavior?

Regards,

Marcin Krotkiewski

Thanks, Mathieu,

I can do that. I might not have been very clear in the first paragraph, 
but the unexpected behavior comes from VTK. Paraview was mentioned here 
only as a simple way to reproduce the problem, and as an example. I'd 
like to avoid bothering too many people at once, but if you still think 
I should re-post, I can do that.

Thanks,

Marcin

Do you mean compared to an older version of VTK/Paraview?  There have been some changes to that code in the last year or so.... Might be revealing to try with older version of Paraview to see...

I've checked Paraview version 5.2 from November 2016. Same behavior.

To further clarify, the issue here is that the vtkLookupTable seems to 
be working with an exclusive interval:

(min, max)

instead of what I think it should do, i.e., working with an inclusive 
interval:

[min, max]

That is, if my point data is in range [min, max], and I use it to 
SetValueRange in a vtkLookupTable, then I would expect that the 
end-point values are also covered by the normal color map, and are not 
considered to be out of range.

Hello,
This is a stupid question from a first time VTK user: I would like to display data using vtkCubeAxisActor2D with custom units for the axes. For example, the physical object extends 15 micrometers into the x-direction, so the x-axis range should be 0 to 15 micrometers and not the length in pixels of the image representation. I do not want to modify the data, just custom display units on axes. How do I do this?

 views
Message-ID: <CALWdf_VxHjSCAB_onz-kO9359hvcoXUsrnZe15QSi9_f4dboFQ@mail.gmail.com>

1. Push the left mouse button.
2. Drag the mouse out of the view, do not release it
3. Click and release right mouse button (or middle button, any button which
was not grabbed). Release left mouse button.
4 In this state you can move mouse back to view. View will behave like left
mouse button is clicked.

Problem is that only left button was grabbing a mouse. Releasing right
mouse button will prevent interactorStyle from receiving  OnLeftButtonUp(),

so when you move mouse into the view  not even it will still remain  in
previously set interaction state, but the appropriate mouse button will not
be grabbed.

This seems like a bug and I would appreciate if anybody could at least
point on work around.
It does not appear on my version of paraview, but I am not sure what fixed
the behaviour.

(I use  vtk 8.1.1 with Qt 5.9)

Best regards,
      Alex

I  can't  help you with alternative and afraid that you can't use
vtkDelaunay2D here, since it assumes that all points lie on 2D plan, while
your points are not.

above or below color range values might be really below or above due to
precision.

I guess you could use SetUseBelowRangeColor and SetUseAboveRangeColor if
you want to enforce such behavior

Those examples seem deprecated, they throw a bunch of errors related to
vtkWidget.h (apparently now vtkOpenGLWidget replaces it?), or simply errors
related to the use of various components.

Which makes it very difficult for vtk/Qt beginners like me and plenty others
if you look at all the posts...

Do you know any reliable recent example? These all seem to strongly depend
on which version of vtk and Qt you're using, and it isn't mentioned.

Hoping to get it to work one day,
Thank you

Hi Oleksandr.


Thank you very much for your help.



I don't think that the problem here is that the vtkDelaunay2D filter is getting 3D points which don't lie on 2D plane.


The vtkDelaunay2D class documentation states:


"The input to this filter is a list of points specified in 3D, even though the triangulation is 2D. Thus the triangulation is constructed in the x-y plane, and the z coordinate is ignored (although carried through to the output)."



And in my program it works basicly most of the time absolutely perfect. Only in some situations it doesn't work and i get the error "Edge not recovered, polygon fill suspect".


I haven't found out when and why it happens and hoped maybe some of you have a clue here. I don't even understand, what this error message means. Some help here would also be great because it would help to find the error.



Or is the vtkDelaunay2D filter buggy?



I also tried using the vtkDelaunay2D filter with points which all lie in a 2D plane to test if your hypothesis is right:


[cid:5796291d-e8d6-41e1-8c7d-3b64b48d48a7]      [cid:ebff186b-999b-462d-a4e2-b289e41e9e06]


But that didn't change anything. Most of the time it works, but sometimes i get the error message above.



Is vtkDelaunay the only vtk triangulation algorithm built in or are there others i haven't found yet?

So far, when i looked through the documentation, i haven't found anything quite like it. If anybody knows some other triangulation filter in vtk (it can be a simple ear-cut algorithm i need nothing special) it would be great to know.



Thanks again.


Regard,

Berti

I then create a polygon mesh which has the shape of the vtkContourWidget polygon selection contour line plus the selected part of the underlying mesh and which lies like a sticker or texture on the the given stl mesh surface:

[cid:inline_00 at geary]

For the reconstruction of the surface i use the vtkDelaunay2D filter using all the points of the vtkContourWidget polygon and the mesh surface points as inputs.

This works absolutely great but depending on the used mesh i sometimes get the following error message from the vtkDelaunay2D filter:

"vtkDelaunay2D (0x556183dcfba0): Edge not recovered, polygon fill suspect"


Does anybody know why this happens and what i can do to get rid of this error?

While nice, but since i don't necessarily need the delaunay properties, is there an alternative to the vtkDelaunay2D filter to get a polygon surface mesh given a bunch of points as an input? (points -> surface)


Thank you very much in advance.

Regards,
Berti

Hi Ashef,

To complement Aron answer, if you would like to support distribution of
your code and leverage existing segmentation and visualization
capabilities, you could consider creating 3D Slicer plugin in either C++ or
Python. 3D Slicer is a medical imaging application built on top of ITK,
VTK, Qt and Python. See https://www.slicer.org/ and
https://www.slicer.org/wiki/Documentation/Nightly/Training

There is also an active forum where you can ask question:
http://discourse.slicer.org/

Doing so, you could leverage a proven and robust platform built on top of
mature libraries.

More specifically, if you already have processing code you could create a
command line module
<https://www.slicer.org/wiki/Documentation/Nightly/Developers/Modules>
implementing the Slicer Execution Model interface (basically an executable
describing itself by passing the --xml parameter), that way you could have
Slicer discover it, generate its UI and expose the processing capabilities
to users.

To illustrate, here are example of segmentation and visualization
capabilities:

 Whole heart segmentation from cardiac CT in 10 minutes:
https://www.youtube.com/watch?v=BJoIexIvtGo
 Creating femur model from CT volume using 3D Slicer:
https://www.youtube.com/watch?v=0at15gjk-Ns
 How to segment multiple vertebrae in spine CT for 3D printing:
https://www.youtube.com/watch?v=Uht6Fwtr9hE
 Quick manual segmentation with contour interpolation:
https://www.youtube.com/watch?v=u93kI1MG6Ic

Let me know if you have questions,
Jc

Hi Cimo,

The use of QVTKWidget is deprecated, please could you try using
QVTKOpenGLWidget instead ?

See

Subject: [vtkusers] Invalidating the OpenGL2 shader cache
Message-ID: <0f9ce3731aba49ac9e45f203ff39dc7c@vytronus.com>

Hi,

   I have come across an interesting problem with VTK and I wanted to ask if there is another way to work around it.


Using the OpenGL2 backend, we have discovered that if another system renders to the same opengl context as VTK,

then the shader cache is put into an invalidated state.


The root problem is that in Rendering/OpenGL2/vtkOpenGLShaderCache.cxx, in vtkOpenGLShaderCache::BindShader(), the lastShaderBound is assumed to not change. VTK assumes that it's the only system setting glUseProgram() for the opengl context.

So if another system clears the GL_CURRENT_PROGRAM value, then VTK doesn't know about it and the following calls to set program uniforms fails with an opengl error.


A suggested is to add a call to glGetIntegerv(GL_CURRENT_PROGRAM, ...) and compare it against this->Handle before returning.


I worked around this problem by clearing the shader cache before invoking vtkRenderWindow::Render() but this required knowing that the shader cache was invalid.


Sincerely,

Ben

Hi,

I need to write a vti file that can be opened in volView or paraveiw. 
I use the below code to convert a series of DICOM files into a vti file. But
the output file size is too big,I want to reduce the size of it.

// Read all the DICOM files in the specified directory.
vtkSmartPointer<vtkDICOMImageReader> reader =

reader->SetDirectoryName(inputFoldername.c_str());
reader->Update();

//write vti
vtkSmartPointer<vtkXMLImageDataWriter> writer =
vtkSmartPointer<vtkXMLImageDataWriter>::New();
writer->SetFileName("head.vti");
writer-> SetInputData(reader->GetOutput());
writer->Write();

I wrote a code in python to generate a depth map of a 3D model and save it

But when I wrote code to generate the point cloud from the image, only part
of the point cloud was generated.

I set the same camera parameters but not work. 

I attached the code and 3D model in this post.

Anyone have any idea? very appreciative.

something similar to this example, except modified for pyqt5:

https://www.vtk.org/Wiki/VTK/Examples/Python/Widgets/EmbedPyQt

Should I be using QVTKOpenGLWidget instead of the QVTKRenderWindowInteractor
with a QFrame? Everything seems to work fine for me. Does the OpenGL widget
have better performance? I've read on kitware blogs that there were recent
OpenGL rendering improvements, but I assumed I was already benefiting from
those since I'm on a recent version acquired through pip or conda.

Thanks!

Hi,

Using vtkExtractVOI is a convenient way of deducing image data size.
If specifying the SampleRate=(2,2,2), the result has a volume 1/8th
the original size.

  // Read all the DICOM files in the specified directory.
  auto reader = vtkSmartPointer<vtkDICOMImageReader>::New();
  reader->SetDirectoryName(inputFoldername.c_str());
  reader->Update();

  int* extent = reader->GetOutput()->GetExtent();

  auto extractVOI = vtkSmartPointer<vtkExtractVOI>::New();
  extractVOI->SetInputData(reader->GetOutput());
  extractVOI->SetVOI(extent);
  extractVOI->SetSampleRate(2, 2, 2);
  extractVOI->Update();

  // write vti
  auto writer = vtkSmartPointer<vtkXMLImageDataWriter>::New();
  writer->SetFileName("head.vti");
  writer->SetInputData(extractVOI->GetOutput());
  writer->Write();

Best

I think for Python, QVTKRenderWindowInteractor is the only option.
QVTKOpenGLWidget is unfortunately not wrapped for Python, since it's
not a vtkObjectBase-derived class (needed for the wrapper generator).

Subject: [vtkusers] QVtkWidget / vtkPointPicker wrong coordinates
Message-ID: <1539767135591-0.post@n5.nabble.com>

Hello,

i'm having trouble using the point picking (but also the "fly to point" from
PCL) when using the PCLVisualizer with QT5. It seems that the vtkPointPicker
does not compute the right x/y/z coordinates.

The problem shows when building eg this git repo:
https://github.com/lesterlo/cloud_annotation_tool and trying to use the fly
to point functionality (by clicking on the vtk widget and hitting the "f"
key). The fly to point jumps to the wrong point.
When instantiating and using a vtkPointPicker myself, i also get the wrong
x/y/z coords (of a point that was not under the mouse cursor)

Funny thing is that it works when using the pclvisualizer stand-alone (eg
not in QT), it seems to work fine.

I found some old questions (without answers) on the mailing list about
vtkPointPicker giving wrong coordinates. In one instance.
I'm using ubuntu bionic which bundles a rather old vtk version.

I don't really know where to start for debugging this problem. Could anybody
give me a hint ?

Frank

Maybe try starting with something like this

https://lorensen.github.io/VTKExamples/site/Cxx/GeometricObjects/Cylinder/

Get that built and running on your system. Then edit that to add in the
openvr codes.

Last I heard glGet calls can sometimes stall the pipeline so I have been
trying to avoid them. I usually use the method clearing the shader cache
when mixing opengl codes and that seems to work.

Dear Ken,

I did as you requested.
In 2D, it works just fine, but when including the vtkOpenVR headers, it cannot build anymore.
The make error message while linking is the same as before.
This is the modified code file: https://pastebin.com/NDk2kzhc (https://pastebin.com/NDk2kzhc)
And the modified CMakeLists: https://pastebin.com/Gs9szZGc (https://pastebin.com/Gs9szZGc)
(This builds and runs with the old vtk version)

Make error message:

	Dear Ken,
I finally managed to get my code building and running on both Windows and Linux.
You can find it here:
https://transfer.sh/gJ1Sg/vtkOpenVRHelloWorld.zip (https://transfer.sh/gJ1Sg/vtkOpenVRHelloWorld.zip)

Unfortunately, it doesn't work with the latest VTK-Version from https://gitlab.kitware.com/vtk/vtk (https://gitlab.kitware.com/vtk/vtk)
After some testing, I found the first commit it doesn't build with: https://gitlab.kitware.com/vtk/vtk/commit/61bc6b5b4b8f0d2d111f6c10af3dd79488f919cc (https://gitlab.kitware.com/vtk/vtk/commit/61bc6b5b4b8f0d2d111f6c10af3dd79488f919cc)
(VTK builds, but my program doesn't build with this VTK Version)

Even though I already use the vtkOpenVR* classes explicitly, it doesn't build.
Is there something else I have to change to make it compatible?

Make produces the following Linker error:

You need to create an use an OpenVRCamera. From your code it doesn't look like you are. I doubt that is the crash but it could be. 
Does the example work on windows? Since linux is an unknown I would think it would be best to make sure you have something working on windows, then port to linux.

Hmm everything looks fine. Maybe something is left over on your VTK build
causing openvr to try to link to factory methods. Make sure

VTK_OPENVR_OBJECT_FACTORY

is off/false in your cmake cache and do a clean rebuild of VTK.

Subject: [vtkusers] VR: Delay in objects following the vive controllers
Message-ID: <98874f317c22c4048d3a612dc69dff1c@dornheim-medical-images.com>

Hello!
I tried out using VTK(master) with openVR and a HTC Vive.
Using the default InteractorStyle(vtkOpenVRInteractorStyle), one can display hints for what the buttons do.
When moving the controllers quickly, these hints follow the controller models delayed.
This also happened in my own experiments with a custom InteractorStyle.

Do you know a way to circumvent this?

Best whishes,
Max.D.

Awesome! Glad you tracked it down and got it working. More recent versions
of VTK removed that option so hopefully it will not bite others like it did
you.

 funding!

Dear VTK community,

I wanted to write to you to ask your support for the Open Anatomy Project, which is the result of the medical imaging analysis and open source software development work done over the last 25 years at the Surgical Planning Lab at Brigham and Women's Hospital. 

If you haven't seen it yet, please visit: https://openanatomy.org

(While you are there, please vote for the Open Anatomy Project as part of a BWH research prize.  Anyone can vote!  Tell your friends!)

We are building ways to publish annotated, structured image and geometry data, the underlying data representation of anatomy atlases but also a great way to represent lots of meaningful visualization data.  The tools we are developing include an atlas data format, web-based data viewers, and a backend community portal for developing collaborative atlases.

Once completed, we hope to have "one button export" from VTK-based applications such as 3D Slicer to produce atlases that can then be published for easy viewing and data reuse.  The portal site will offer Wikipedia-like user access to atlases and a vaguely GitHub-like developer experience.

We are publishing atlases that we have developed over the years, but that's just the start.  We want to build up a rich library of atlases, the pieces of which can be used for any purpose (3D printing, VR, ...).  This site ultimately will be one-stop shopping for medical atlases of all sorts, including normal anatomy, anatomical variations, pathology, and surgical plans.

We already using these atlases for educational outreach around the globe. For instance, we are working with African medical partners to develop medical classroom materials to teach the next generation of African medical students.

This is a grand but important vision. We are just at the beginning of this project.  But the success of the VTK, ITK, and Slicer communities proves to us that vibrant communities can emerge around meaningful software and data projects.  Your help is welcome!

Could you please vote for our project by following the "Vote" link when you visit our home page at https://openanatomy.org ? It will help us secure next year's funding and raise the profile of the project.

Thanks so much.
Michael Halle
Ron Kikinis
and the rest of the Open Anatomy Team.

Hello,

For reference:

i managed to fix this by switching to QVTKOpenGLWidget. Unfortunately this
requires PCL from master (for reference: this
http://www.pcl-users.org/QVTKOpenGLWidget-Qt-PCLVisualizer-td4045158.html is
not yet in a released version).

Now i have some other issues: i need to run it with
MESA_GL_VERSION_OVERRIDE=3.2 otherwise i get this:

     vtkShaderProgram (0x563e8e366510): 0:1(10): error: GLSL 1.50 is not
supported

thanks,
Frank

Hello!
Is it possible to sample an implicit function into an existing vtkImageData Object?
Something the just replaces/fills all voxels 'inside' the function with a given value and leave the rest as-is.

Best wishes,

Subject: [vtkusers] vtkMultiVolume,
 vtkOpenGLGPUVolumeRayCastMapper::vtkInternal::ClearRemovedInputs()
 throws SegFault during/after Render
Message-ID: <2398843.lChJ16j1jy@hekate>

Hello,

I have a question about using vtkMultiVolume. I am using the nightly-master to 
use vtkMultiVolume for a bachelor thesis about multi-modal medical images 
rendering possibilities. I get a SegFault as soon as I have removed input 
connections of the mapper ports and wonder if there is an error in VTK or if I 
am using it wrong.

My simple prototype has no problem - it hardly does a thing, as it is roughly 
based on this (https://gitlab.kitware.com/vtk/vtk/blob/nightly-master/
Rendering/Volume/Testing/Cxx/TestGPURayCastMultiVolumeAddRemove.cxx).

But the "real" implementation has problems. It is inside a large code base 
with lots of GUI triggers that result in Rendering, so it might be a missing 
call to Render or one too many at the wrong time.

(After / While?) Rendering from vtkOpenGLRenderer::UpdateGeometry (https://
gitlab.kitware.com/vtk/vtk/blob/nightly-master/Rendering/OpenGL2/
vtkOpenGLRenderer.cxx#L335), vtkMultiVolume::RenderVolumetricGeometry 
(https://gitlab.kitware.com/vtk/vtk/blob/nightly-master/Rendering/Volume/
vtkMultiVolume.cxx#L275) calls its Mapper to Render and 
vtkOpenGLGPUVolumeRayCastMapper::GPURender (https://gitlab.kitware.com/vtk/
vtk/blame/b8ab2d693a54024b7e81cb57a32c289cb7dc8314/Rendering/VolumeOpenGL2/
vtkOpenGLGPUVolumeRayCastMapper.cxx#L3324) tries to clear up the removed 
inputs here: https://gitlab.kitware.com/vtk/vtk/blame/
b8ab2d693a54024b7e81cb57a32c289cb7dc8314/Rendering/VolumeOpenGL2/
vtkOpenGLGPUVolumeRayCastMapper.cxx#L3162

At that moment input.GradientOpacityTables, input.OpacityTables and 
input.RGBTables are vtkSmartPointer with a nullptr as pointed object.

A quick fix is to change the code like so:
if( input.GradientOpacityTables ) input.GradientOpacityTables-
>ReleaseGraphicsResources(win);

But I am concerned I might be masking the symptom of my using vtkMultiVolume 
the wrong way. Anybody out there who can help and tell me of a better way to 
fix that bug?

Regards,
A. Ophagen

For some reason I can't see my question in mail, so I am not sure was it
posted, but was not replied or never ended up in the mailing list.

1. Could anybody confirm that it was posted on mailing list?
2. Can anybody give a hint how to notify interactor style (reset mode) when
even propagated to other widget?

Best regards,
          Alex

I think VTK has wrong assumption about mesa gl version and capabilities.
And we found that setting MESA_GL_VERSION_OVERRIDE is the only workaround.
Why do you think this is a problem?

By the way you would have the same problem before, but for QVTKWidget that
was not a requirement.

I figure out the problem. When I use the vtkBMPReader, the output of this
class is a 3 channel vtkImageData, but the vtkDepthImageToPointCloud only
receive a 1 channel depth image. So We need to use vtkImageExtractComponents
to get the first channel of the vtkBMPReader output.  

But I still don't understand how vtk compute projection transform matrix.

Hi Alex,

I see your original message from Monday, so it seems it was posted successfully.

Regarding your question, I?m assuming each of the interactorstyles is in a different Qt widget?  If so, you could use Qt leave events to reset the state of the interactor whenever the mouse leaves the rendering area.  I?m not sure offhand if there?s a single method to reset the internal state of the interactorsyle, you may have to query GetState and then end whatever the interaction is.

Hope that helps,
Jason

For some reason I can't see my question in mail, so I am not sure was it posted, but was not replied or never ended up in the mailing list.

1. Could anybody confirm that it was posted on mailing list?
2. Can anybody give a hint how to notify interactor style (reset mode) when even propagated to other widget?

Best regards,

Problem is that only left button was grabbing a mouse. Releasing right mouse button will prevent interactorStyle from receiving  OnLeftButtonUp(),

so when you move mouse into the view  not even it will still remain  in previously set interaction state, but the appropriate mouse button will not be grabbed.

This seems like a bug and I would appreciate if anybody could at least point on work around.
It does not appear on my version of paraview, but I am not sure what fixed the behaviour.

(I use  vtk 8.1.1 with Qt 5.9)

Subject: [vtkusers] vtkOBJImporter can't read the whole mesh of an obj file
 including several parts
Message-ID: <1539985435003-0.post@n5.nabble.com>

Hi,everyone!

I use vtkOBJImporter to read an obj file including several parts (the file
is from shapenet  https://www.shapenet.org/ <https://www.shapenet.org/>  
models.zip <http://vtk.1045678.n5.nabble.com/file/t342591/models.zip>  ).
But it can only read part of it. I also try to use paraview, but get the
same results. The following is the code:(its's the example code on
website.). 

Thanks.


  vtkNew<vtkOBJImporter> importer;

  importer->SetFileName(filenameOBJ.data());
  importer->SetFileNameMTL(filenameMTL.data());
  importer->SetTexturePath(texturePath.data());

  vtkNew<vtkRenderer> ren;
  vtkNew<vtkRenderWindow> renWin;
  vtkNew<vtkRenderWindowInteractor> iren;

  renWin->AddRenderer(ren);
  iren->SetRenderWindow(renWin);
  importer->SetRenderWindow(renWin);
  importer->Update();

  renWin->SetSize(800,600);
  ren->SetBackground(0.4,0.5,0.6);
  ren->ResetCamera();
  renWin->Render();

Many thanks Jason for response!

I did manage to fix the problem
by adding
interactorStyle()->OnLeave();
interactorStyle()->OnLeftButtonUp();
interactorStyle()->OnMiddleButtonUp();
interactorStyle()->OnRightButtonUp();
interactorStyle()->OnFourthButtonUp();
interactorStyle()->OnFifthButtonUp();
to specific widget subclass

But this seems a wrong place for this fix.
QVTKOpenGLWidget should invoke such behavior (as I believe QVTKWidget was
doing).

Another problem is that I am not sure what function to call.
First impression is to call  OnLeave(), but it does not have any effect on
the vtkInteractorStyleTrackballCam.
I definitely can subclass every interactor style and override OnLeave() to
do a proper job,  but this seems was working with QVTKWidget  somehow, so I
would rather not subclass every vtkInteractorStyle to fix the behavior
which supposed to work already.

So I do have a workaround which requires a significant changes in
application, counting the number of places QVTKOpenGLWidget and
vtkInteractorStyle subclasses are used.

Hi,
I am trying to draw a cuboid in pcl viewer by clicking two diagonal points
in pcl viewer.The callback function does not return the accurate points
sometimes hence in certain cases either the cuboid drawn is larger than
required or the cuboid is shifted and doesn't get drawn at clicked points.

Could you please let me know what can be the issue and how to resolve it.

I import the file in blender. I find there are 2000+ components but
vtkOBJImporter said only 91 actors. Is this a bug of OBJImporter?

Looks like a bug. There are only 91 unique materials for all of the
components. Many components share materials and it seems the importer
can't handle it.

I'll take a look.

Hi,

I noticed that the class hierarchy of vtkAbstractMapper has non-virtual ShallowCopy methods whereas the vtkDataObject and vtkProp hierarchies have virtual ShallowCopy. To me this came as a surprise. Is it intentional to have non-virtual ShallowCopy or can I make a contribution to make these virtual?

Please do submit a merge request Andreas,

I don't see any reason for that not to be virtual.
It has been that way since at least 2001, maybe for efficiency.

Actually, the API looks odd to me. DeepCopy/ShallowCopy make sense for
data objects since the definition (and distinction) between the two is
reasonable. What does ShallowCopy mean for non-data objects? Unclear.
If the intent is to allow copying parameters (note, there's no API for
that for general VTK objects), we may want to rename it at the very
least.

Subject: [vtkusers] How's the Projection Transform Matrix computed in
 VTK?
Message-ID: <4A2A9A281AE5D54CA205FB13069FD874017ACF1764@US01WEMBX2.internal.synopsys.com>

Hi maskjp,

What I found so far, is that for some reason the depth buffer is filled with 1.0s and not 0.0s as one could expect. I asked about that before and I got no answer.

To get the correct projection matrix, you can use this in C++, assuming a vtkRenderer* renderer

vtkCamera* camera = renderer->GetActiveCamera();
vtkSmartPointer<vtkMatrix4x4> projection  = vtkSmartPointer<vtkMatrix4x4>::New();
projection->DeepCopy( camera->GetCompositeProjectionTransformMatrix( renderer->GetTiledAspectRation(), 0.0, 1.0) ); // This maps the z-buffer from 0.0 to 1.0.

I found this usage in classes like vtkRenderer and vtkVolume source code. Hope that helps.

Cheers,
Pato

Message-ID: <1540252201965-0.post@n5.nabble.com>

I have two overlapping mesh objects in my renderwindow. I have a small 3D
scan sticking on top of a larger scan of the same scene as a result of ICP
algorithm. Now I want to get rid of the part of the larger scan that is
close the surface of smaller 3D scan. How do I go about this?

Subject: [vtkusers] Print 2d Image on context
Message-ID: <CAJrRwvjCy_CBjmMJZNef3T9m4G4srWrjGopCBQUYBVqFbygVkw@mail.gmail.com>

Hello, I'm using vtk.js to render some nifti images, I have 3 "windows"
showing the same image on different angles, coronal, sagittal and
transverse, when I click on a specific point on one of the images, I set
the slices on the other images based on the point I clicked, so if I click
on the sagittal view on some point, it will grab the y and z slices from
that point and set the slices on the respective mappers.

What I need to do now is to add a "crosshair" png, setting the point I just
clicked on the window, I dont want that crosshair image to have zoom
applied to it (if possible) when I zoom the window. Should I use the
vtkActor2D and some imageMapper? I have not idea on where to begin or even
if thats possible at all.

I believe this is a limitation of VTK. Translucent polygonal geometry with
opacity != 1.0 can't be rendered intersected with a volume other than in a
back-to-front or front-to-back manner.

Someone correct me if I'm wrong (we'd also very much like to be able to do
this).

Hi Elvis and Ken,

Thanks for the help. What it seems to start to work for me, is to use layered renderers: using two renderers, and using the first for my volume and the second for the plane. Currently I?m dealing with the depth buffer definition as I couldn?t find its definition yet in VTK code, but so far, I could draw some extent of the translucent plane in front and the other back.

I think that by fixing the depth buffer definition in my code, I would be able to mimic this behavior. I will poke you again if I succeed.

Cheers,
Pato

Hi Pato,

You need to use vtkRenderer::SetUseDepthPeeling(true) along with
vtkRenderer::SetUseDepthPeelingForVolumes(true).

We have a test for this sort of thing - TestGPURayCastDepthPeelingTransVol
that renders two translucent spheres (polydata) and a volume (vase). See
the image below:

Sorry for the misinformation! Depth peeling indeed should make it possible.

Subject: [vtkusers] Problem compiling a project uses VTK
Message-ID: <CANxr+WSSqrGVJv1WsXeH9otstYmqaQ+MoOFAcC72QH5gh6WSMQ@mail.gmail.com>

I'm trying to build and use a project for my thesis (
https://miccai.creatis.insa-lyon.fr/miccai/core/EvaluationMetrics.zip)
which needs VTK libraries such as 'vtkProcessObject.h' to be accessible.
Unfortunately, these libraries seem to be removeed from VTK. I'm wondering
how I can compile a full version of VTK?

It looks like your file is available in vtk 5.  Vtk 5 is available for
installation on Ubuntu 16.04, so if that's the system you happen to be
developing on, you're good to go.

In the worst case, you can download vtk (tag 5.10.1) from the development
repository, and compile it yourself:
https://gitlab.kitware.com/vtk/vtk/tree/v5.10.1

Good luck.

Subject: [vtkusers] vtkDICOMImageReader
Message-ID: <1540375464363-0.post@n5.nabble.com>

Hi, 
I'm using ActiViz.NET by Kitware to create a Console App with Visual Studio.
I am trying to read some DICOM images and render them. I have been able to
do so, but I would like to improve my code. I have many DICOM series of a
single subject taken at different time. I aim to load all the DICOM
togheter, when my app starts, so that then I am able to switch between them
without waiting the DICOMImageReader loading process. I need some sort of
DICOMImageReader array, in which different series are loaded in different
array slots. In this way I would be able to select the DICOM series to
render simply thanks to an index selection. Unfortunately, DICOMImageReader
does not support time frames. Is there a class that I could use to store
multiple DICOMImageReader output? 
Thanks for your help.

Cmake: v3.12.2-win64-x64

I am building a program that requires an older version of vtk due to
compatibility issues. I have currently downloaded VTK v5.0.0 from (
https://gitlab.kitware.com/vtk/vtk/tree/v5.0.0) but I get missing library
error (cannot open input file......vtkRendering.lib) when i compile in
visual studio; this is after i have configured/generated in cmake. Any idea
how I might get this library or how to avoid this error to compile vtk 5.0?

Hi A,

Seems like you have a bug fix. Mind contributing it to VTK?

Take a look at

Subject: [vtkusers] Difference between vtkSmartPointer assignment operator
 and ShallowCopy
Message-ID: <HE1PR0801MB2073D9FA06557CF38AA7527981F60@HE1PR0801MB2073.eurprd08.prod.outlook.com>

Hello.

I (hopefully) already understand the difference between the ShallowCopy and the DeepCopy method (e.g. copying only the pointer vs. copying the pointer and the content pointed to).

But what i don't understand yet is, what is the difference between using the overloaded assignment operator of vtkSmartPointer and the ShallowCopy method, e.g. what is the difference between


vtkSmartPointer<vtkPolydata> myStrangePolydata = vtkSmartPointer<vtkPolydata>::New();


myStrangePolydata = vtkTransmogrifyFilter->GetOutput();


and


myStangePolydata->ShallowCopy(vtkTransmogrifyFilter->GetOutput();



Does it make a difference to the reference count of the vtkSmartPointer?


Thank you very much in advance.


Cheers,
Berti

vtkSmartPointer has nothing to do with neither deep or shallow copy.

if you assign vtk object to smartpointer the reference count of vtk object
is incremented,
there is only one vtkObject in the memory. Once smartpointer is released
(going out of scope  for example) vtk object reference count  it was
pointing is decremented.
In another words vtkSmartPointer is like a normal pointer, which adds does
reference couning.

Operations with smartpointer DO NOT copy any data related to the object
they point to.


While deep and shalow copy are always performed with 2 different objects.

Subject: [vtkusers] Difference between vtkSmartPointer assignment

Thanks Oleksandr for the great answer.

OK, i see, so when i use ShallowCopy, i copy the underlying structure of the vtk object e.g. attributes like the pointers the vtk object consists of without copying the content which the pointers point to.

So for example by using a ShallowCopy on a vtkPolydata object i copy all the underlying pointers to things like vtkPointSet, vtkDataSet, Cells, Lines, Vertices, Points etc. which a vtkPolydata object is composed of but unlike using a DeepCopy not the actual content (vertices and stuff arrays) which these pointers point to.

By using the vtkSmartPointer i get a reference counted pointer to the vtkObject without transfering the ownership of this object. It only increments the lease count by one and if the lease count becomes zero the destructor of the object is called.



Just one question:

Does every vtk filter copies the data it is given to?

e.g.

When using


    vtkNew<vtkTransformPolyDataFilter> transformFilter;

    transformFilter->SetInputData(polyData);

    transformFilter->SetTransform(transformation);

    transformFilter->Update();



does the polyData exists twice in memory (the original polyData and the filter keeps its own transformed copy of the polyData)?



Thanks and regards,


Berti

vtkSmartPointer has nothing to do with neither deep or shallow copy.

if you assign vtk object to smartpointer the reference count of vtk object is incremented,
there is only one vtkObject in the memory. Once smartpointer is released (going out of scope  for example) vtk object reference count  it was pointing is decremented.
In another words vtkSmartPointer is like a normal pointer, which adds does reference couning.

Operations with smartpointer DO NOT copy any data related to the object they point to.


While deep and shalow copy are always performed with 2 different objects.

Hello.

I (hopefully) already understand the difference between the ShallowCopy and the DeepCopy method (e.g. copying only the pointer vs. copying the pointer and the content pointed to).

But what i don't understand yet is, what is the difference between using the overloaded assignment operator of vtkSmartPointer and the ShallowCopy method, e.g. what is the difference between


vtkSmartPointer<vtkPolydata> myStrangePolydata = vtkSmartPointer<vtkPolydata>::New();


myStrangePolydata = vtkTransmogrifyFilter->GetOutput();


and


myStangePolydata->ShallowCopy(vtkTransmogrifyFilter->GetOutput();



Does it make a difference to the reference count of the vtkSmartPointer?


Thank you very much in advance.

Typical filter does not change the input.

vtkNew<vtkPolyData> polyData; // assume polydata reference count =1

{

    vtkNew<vtkTransformPolyDataFilter> transformFilter;
    transformFilter->SetInputData(polyData); // polyData reference
count is incremented = 2

    transformFilter->SetTransform(transformation);

    transformFilter->Update(); // filter produced new polydata with count 1

// at this point there are 2 polydata in the memory

}
// smartpointer deleted transformFilter

// output polydata is deleted since its reference count dropped to 0


// polyData reference count is incremented = 1

Funny that this would come up. I recently tracked down an unusually
high memory usage in our application. It turned out it was simple
matter of us not "terminating" a pipeline at the right place in a
function that creates an image data (valgrind's massif tool led me to
it).

E.g. we had something like

vtkSmartPointer<vtkVolume> createVolume(....) {
    auto reader = vtkSmartPointer<OurImageReader>::New();
    ...

    auto extract = vtkSmartPointer<vtkExtractVOI>::New();
    extract->SetInputConnection(reader->GetOutputPort());
    ...

    auto threshold = vtkSmartPointer<vtkImageThreshold>::New();
    threshold->SetInputConnection(extract->GetOutputPort());
    ...

    auto mapper = vtkSmartPointer<vtkGPUVolumeRayCastMapper>::New();
    mapper->SetInputConnection(threshold->GetOutputPort());
    ...

    auto volume = vtkSmartPointer<vtkVolume>::New();
    volume->SetMapper(mapper);
    volume->Update();
    ...

    return volume;
}

In this case, we had no need for keeping around the
reader/extract/threshold part of the pipeline, but since there there
were back-references back through the pipeline, these elements were
kept around and the copies of the data that they had were taking up
pretty big chunks of memory (or well, at least the threshold filter
did if I remember correctly).

The solution was simply to change

    auto threshold = vtkSmartPointer<vtkImageThreshold>::New();
    threshold->SetInputConnection(extract->GetOutputPort());
    ...

    auto mapper = vtkSmartPointer<vtkGPUVolumeRayCastMapper>::New();
    mapper->SetInputConnection(threshold->GetOutputPort());
    ...

to


    auto threshold = vtkSmartPointer<vtkImageThreshold>::New();
    threshold->SetInputConnection(extract->GetOutputPort());
    threshold->Update();
    ...

    auto mapper = vtkSmartPointer<vtkGPUVolumeRayCastMapper>::New();
    mapper->SetInputData(threshold->GetOutput());
    ...

in order to "cut off" the pipeline and let those parts of the pipeline
destruct when the function returns.

Just thought I should mention this as a potential gotcha, where you're
looking for issues where the memory usage is unusually high.

Hi all
I have installed VTK6.3 and i want to read a multi-frame DICOM image,
unfortunately the vtkDICOMImageReader can't open my files.
I also have tried to decompress the file using gdcm but it didn't work,
also tried to split the file into a series of images but i can't know which
tags are necessary to the reader in order to read the series, any help
would be appreciated.

Thanks

Hi Severin,

We are using cropping planes successfully - so they can be made to work. 

We set up our clipping plane in the same way, and similarly set the origin (and normal). So as the code looks OK, perhaps it is a problem with some of the values?

For investigating cropping planes we found modifying the "GPURenderDemo" example a helpful way of getting things working. We would make it work interactively there and then check/hard code the values in our application to achieve the same result and then work from there.

There is definitely a learning curve to VTK, so I hope you get it working soon.

Subject: [vtkusers] Correct use of vtkClipVolume in volume rendering?

Hi everyone,

It is indeed a basic question but I've striven to find any example or explanation in the mailing list or forum or stack overflow concerning this. 

I have a .mhd file that I render in volume following the medical volume rendering example.

I'd like to implement volume exploration for this, so I think about using a plane (then spheres etc.) to clip the volume. 
But my following code has no effect, and I guess I need to use vtkClipVolume, but there zero information about how to use it in the documentation.

  Code :
//Plane clipping
vtkSmartPointer<vtkPlane> cuttingPlane =
  vtkSmartPointer<vtkPlane>::New();
cuttingPlane->SetOrigin(0, 0, 0);

volumeMapper->AddClippingPlane(cuttingPlane);


Thank you very much for your help,
I find learning VTK is drastically slowed down because of missing information.
Severin

That's a solution. Unfortunately I don't know how many DICOM series the app
will need to read, since I could have a different time frame number for
different subjects. I would like to avoid to instatiate object that I won't
use (vtkDICOMImageReader number > time frame) or have a limit on the time
frame number that I can read.
Anyway thanks for your advice.

Subject: [vtkusers] Multi-texturing??
Message-ID: <YQBPR0101MB2084EA308CCD0542A5177DF7D1F70@YQBPR0101MB2084.CANPRD01.PROD.OUTLOOK.COM>

Hi.


I am trying to use a second texture in a fragment shader.


vtkActor::SetTexture(vtkTexture*) seems to only take a single texture image and no way to add more.


vtkActor::GetProperty()->SetTexture(textureUnit, vtkTexture*) is deprecated and shows an error in an output window, and doesn't seem to pass any other texture variable to the shader.


I've looked and looked, and I'm probably blind, but how do I do this seemingly simple task?


Thanks.

Patrick

Thank you very much, Jean-Christophe.

Finally managed to write hierarchy files wrapping on base of macro "vtkMacroKitPythonWrap", it solved the issue.

Best regards,

Subject: [vtkusers] vtkMultiVolume,
 vtkOpenGLGPUVolumeRayCastMapper - How to use
 vtkVolume->GetProperty()->SetScalarOpacity( vtkPiecewiseFunction )
 correctly?
Message-ID: <3103625.u6C8mHh0Y9@hekate>

Hello,

I am trying to use vtkMultiVolume for a rather large application for 3D medical image data to meld multiple data - as my bachelor thesis project. I have based my code on commit https://gitlab.kitware.com/vtk/vtk/commit/9db353bb72c5567c4b75573b79517ec090d8df02 of the VTK and on branch nightly-master.
I need color transfer functions, scalar opacity functions and image data separately for each volume. I cannot get the scalar opacity to do what I want, somehow. Even in a very small example*, alpha is 1 all over the volume in the end. Gradient opacity, which I do not need, afaik, will result in alpha values smaller 1.

I have debugged the shader source code right before they are given to openGL, I have stepped through the vtlVolumeInputHelper and vtkTextureObject and vtkOpenGLVolumeOpacityTable and checked the values of the actual float-Array and - kind of** - found my expected values in there until just before they were given to openGL. From all I have seen, there should be semi-transparent parts to my generated cuboids. I have not altered bias or scale of any volume or the multivolume and presume them to be 0 and 1 respectively.

I temporarily changed the fragment shader template to try and output the LUT values (for the 1st volume) instead of the image values***. The whole "volume" in my render window was opaque white. That was the trick I am most unfamiliar with, so it might have just failed to do what I wanted.

Have I not used vtkMultiVolume and  vtkOpenGLGPUVolumeRayCastMapper in the way they are supposed to be used?
Please have a look at my small example code*. 

Regards,
A. Ophagen

Hm, I tried your code and can't reproduce the problem. It would be
good with a screenshot of what you're seeing.

When I run it, volumes are showing some transparency. See attached
pic1.png and pic2.png.

Keep in mind that the value produced by the opacity transfer function
is how much opacity is accumulated by a cast ray over one
ScalarOpacityUnitDistance (see this property on vtkVolumeProperty). It
defaults to 1.0 VTK world unit.

This means that, given the opacity functions you've set up in your
code, your 64x64x64, which have a spacing of 1.0, are going to look
mostly opaque (but not completely).

As an example, I changed all your opacity functions to go from opacity
0.0 to 0.1 instead (see pic3.png). Now it's easier to see that there's
some transparency.

Put another way, with the ScalarOpacityUnitDistance set to its default
value (1.0) and a 1.0 voxel spacing, you can think of your opacity
transfer function as giving the opacity of one voxel. Since your
volumes are 64x64x64 voxels, they're going to look roughly 64 times
more opaque than your opacity function says.

There's really 4 things that influence the opacity of a rendered volume

- The number of voxels that you're "looking through" (the extent of your volume)
- The spacing between those voxels (the spacing of your volume)
- The scalar opacity unit distance (the ScalarOpacityUnitDistance property)
- The opacity transfer function

HTH,
Elvis

Thanks a lot!

If I understand you correctly, when I want my opacityTransferFunction to 
signify the transfer function for the whole dataset, I will need to set the 
ScalarOpacityUnitDistance to the maxValue - minValue of the dataset? Or is it 
the max size of the dataset? In this case they are the same values, because I 
was lazy with the test data.

I will immediately test that. We afaik never used ScalarOpacityUnitDistance 
before. Is it a new mechanism? As of now, we already use Release VTK 8.1 and 
it seems strange that our medical datasets look just like we want them when 
all we used to set were color and scalar opacity.

The example has a teeny weeny value range and I am not excluding any of its 
value range, which is very different from a 'real' dataset.

We are talking about medical images and they sometimes have a range that is 
already clamped by DICOM having only an amount of int16-range of values - of 
course you usually have invisible background, but in case of medical data - a 
LOT of the data is invisible most of the time. 

I am mapping the opacity to the grey values of the dataset. When I have a 
trapezoid function, I usually start at some grey value with 0 opacity then two 
nodes with some visibility and then another (lighter) grey value again with 
zero opacity. This function to me defines the opacity of the dataset, in it's 
entirety. Which additional information do I give the volume property with 
ScalarOpacityUnitDistance?

Should I put additional zero opacity nodes at the extremes of the dataset's 
value range, too? In case of a triangular function like so: _/\_ ?

To me, that seems weird, because I just presume anything below range-min is 
zero and anything above range-max is zero. Unless you use the clamping, that 
is.

Thanks again!

Subject: [vtkusers] Can't run build vtk from source with python wrappings
Message-ID: <72BCADE7-0FD5-4240-9CBC-6F2422A9291B@gmail.com>

Hello, I?m trying to run vtk with python wrappings build from source https://gitlab.kitware.com/vtk/vtk.git. Target os - MacOs, python version 3.6. The basic call of ?import vtk? from python gives error that libraries can?t be loaded (python program from https://www.vtk.org/Wiki/VTK/Examples/Python/Cylinder <https://www.vtk.org/Wiki/VTK/Examples/Python/Cylinder>):


Traceback (most recent call last):
  File "/Users/evgeniya/anaconda3/lib/python3.6/site-packages/vtk/vtkCommonCore.py", line 5, in <module>

  Referenced from: /Users/evgeniya/anaconda3/lib/python3.6/site-packages/vtk/vtkCommonCorePython.so

During handling of the above exception, another exception occurred:

    from vtkCommonCorePython import *
ModuleNotFoundError: No module named ?vtkCommonCorePython'

This is the error with added path to /Users/evgeniya/anaconda3/lib/python3.6/site-packages/vtk/ to PYTHONPATH variable.

Looks very much like libraries are found but can?t be loaded for some reasons. Any suggestions what can cause such an error?

Thank you very much in advance,
Best regards,
Evgeniya

Does the issue exist only when depth peeling is enabled? Do you see it
rendering correctly when depth peeling is disabled?

Ensure that the color and depth buffers are preserved with the renderer :

_renderer->SetPreserveColorBuffer(1);
_renderer->SetPreserveDepthBuffer(1);

?

Hi,

If you explicitly set or update DYLD_LIBRARY_PATH environment variable
first with the path"
/Users/evgeniya/anaconda3/lib/python3.6/site-packages/vtk/", are you able
to import ?

While sub-optimal, knowing that this work would provide good information.

No, looks like updating DYLS_LIBRARY_PATH didn?t solve the problem.

However, vtkpython works well. Just come across this description:
https://stackoverflow.com/questions/48148376/running-vtk-from-python-not-just-vtkpython

The similar check gives me similar list of dependencies with vtk python depending on libpython3.6m.dylib:
otool -L libvtkCommonCorePython36D-8.2.1.dylib
libvtkCommonCorePython36D-8.2.1.dylib:

Hi,

I see. As an alternative approach, you could also look into building VTK
python package using https://github.com/jcfr/VTKPythonPackage

This is what is used to build the VTK python wheels. That said, note that
we are are not yet officially supporting VTK python wheels.

Subject: [vtkusers] Creating a fly through in vtk
Message-ID: <1540625915077-0.post@n5.nabble.com>

I want to create a smooth 'fly though' like rendering in vtk. I have a 3D
scene and want to create a movie using successive camera poses. Can this be
done in vtk?

Just a suggestion. From what I see,  the code implements standard
medical image segmentation quality metrics, like HausdorffDistance and
etc. Those are implemented, well tested and fast in ITK
(https://itk.org/Doxygen/html/classitk_1_1HausdorffDistanceImageFilter.html),
and VTK main purpose of use is visualization tasks.  You can play with
the ITK algorithms from python (for example
http://insightsoftwareconsortium.github.io/SimpleITK-Notebooks/Python_html/34_Segmentation_Evaluation.html
or you can google other examples), before modifying and creating
something new on the base of existing algorithms.  That is of course
if you don't have a particular task to use the suggested vtk based
code.

Best regards,
Evgeniya

Subject: [vtkusers] Can't read image with VTK
Message-ID: <1540707920888-0.post@n5.nabble.com>

Hi,
I have a question when I use VTK with CLion. I'm using VTK 8.1 in c++ build
with cmake3.12. When I read image by using class *"vtkMetaImageReader"(other
class inheriting "vtkImageReader2" have the same problem*), the program
crash with "*Process finished with exit code -1073741515
(0xC0000135)*"(display in clion). But class "vtkStructuredPointsReader" can
run correctly. I think it may lack some libraries related with image. Now, I
have no idea with this problem.

CMakeLists.txt

  /cmake_minimum_required(VERSION 3.12)
  project(vtk_demo)

  set(CMAKE_CXX_STANDARD 14)

  aux_source_directory(src SOURCE_FILES)
  set(RES_FILES res/brain.mhd res/brain.raw)
  include_directories(include)

  #vtk
  set(VTK_DIR G:\\VTK)
  find_package(VTK REQUIRED)
  include(${VTK_USE_FILE})

  add_executable(vtk_demo ${SOURCE_FILES} ${RES_FILES})
  target_link_libraries(vtk_demo ${VTK_LIBRARIES})/



main.cpp

  /#include <vtkSmartPointer.h>
  #include <vtkImageViewer2.h>
  #include <vtkRenderWindow.h>
  #include <vtkRenderWindowInteractor.h>
  #include <vtkRenderer.h>
  #include <vtkMetaImageReader.h>


  int main(int argc, char* argv[])
  {

      auto reader =
              vtkSmartPointer<vtkMetaImageReader>::New();
      reader->SetFileName("../res/brain.mhd");
      reader->Update();

      auto imageViewer =
              vtkSmartPointer<vtkImageViewer2>::New();
      imageViewer->SetInputConnection(reader->GetOutputPort());

      auto renderWindowInteractor =
              vtkSmartPointer<vtkRenderWindowInteractor>::New();
      imageViewer->SetupInteractor(renderWindowInteractor);

      imageViewer->SetColorLevel(500);
      imageViewer->SetColorWindow(2000);
      imageViewer->SetSlice(40);
      imageViewer->SetSliceOrientationToXY();
      imageViewer->Render();

      imageViewer->GetRenderer()->SetBackground(1.0, 1.0, 1.0);
      imageViewer->SetSize(640, 480);
      imageViewer->GetRenderWindow()->SetWindowName("DisplayImageExample");

      renderWindowInteractor->Start();

      return 0;
  }

Thank you very much in advance,
Best regards,
Franks

Subject: [vtkusers] Image from OpenCV as texture
Message-ID: <D1F05588-DC36-400A-AF54-4B2F1733AEE3@gmail.com>

Dear list

My final goal is to render a movie (read by the openCV method VideoCapture) on a plane in 3D space (using VTK). 

As a first step I tried to map a single RGB-frame (a numpy nd.array (1020, 720,3)  ) as texture on a plane (see the code snippet below).
However this does not work. What I don?t get is how to create a 2D color image to map to the texture. Now it is recognized as a 3D texture map and returns the error: "3D texture maps currently are not supported!?.

As I am very new to VTK and do not know anything about C++, I find it difficult to orient myself in VTK through the C++ examples. 
So, any hints would be greatly appreciated!

Best
Andreas


# Python 3.6, VTK 8.1.1, OpenCV 3.4.2)

# Create a video capture object to read videos
cap = cv2.VideoCapture(VIDEOPATH)

# Read first frame
success, frame = cap.read()

frame_shape = frame.shape
vtk_array  = numpy_support.numpy_to_vtk(frame.transpose(2, 0, 1).ravel(), deep=True, array_type=vtk.VTK_UNSIGNED_CHAR)

# Convert vtkFloatArray to vtkImageData
vtk_image_data = vtk.vtkImageData()
vtk_image_data.SetDimensions(frame.shape)
vtk_image_data.SetSpacing([1,1,1])
vtk_image_data.GetPointData().SetScalars(vtk_array)
vtk_image_data.SetOrigin(0,0,0)

# create the texture
atext = vtk.vtkTexture()
atext.SetInputData(vtk_image_data)
atext.InterpolateOn()

plane = vtk.vtkPlaneSource()
?

I have solved this problem. Add your tiff path(tiff/bin) to environmental
variable and then vtk will work fine.

I came across a similar problem when I was working on a VTK application in
Python. There are few examples of how to do this (if any).

Take a look at this excerpt of code that I use to load in RGB data. In
short, the answer to your problem is to have the data is NxM where N is the
product of the size of the data (i.e. 10x10x10 => N = 1000) and M is the
number of color channels you have (1 for grayscale, 3 for RGB, 4 for RGBA).

# Use VTK support function to convert Numpy to VTK array
# The data is reshaped to one long 2D array where the first dimension is
the data and the second dimension is
# the color channels (1, 3 or 4 typically)
# Note: Fortran memory ordering is required to import the data correctly
# Type is not specified, default is to use type of Numpy array
vtkArray = numpy_support.numpy_to_vtk(self.data.reshape((-1,
self.channels), order='F'), deep=False)

# Create image, set parameters and import data
self.vtkImage = vtkImageData()

# For vtkImage, dimensions, spacing and origin is assumed to be 3D. VTK
images cannot be larger than 3D and if
# they are less than 3D, the remaining dimensions should be set to default
values. The function padRightMinimum
# adds default values to make the list 3D.
self.vtkImage.SetDimensions(padRightMinimum(self.size, 3, 1))
self.vtkImage.SetSpacing(padRightMinimum(self.spacing, 3, 1))
self.vtkImage.SetOrigin(padRightMinimum(self.origin, 3, 0))

# Import the data (vtkArray) into the vtkImage
self.vtkImage.GetPointData().SetScalars(vtkArray)

Dear Mr. Patel
   I have the same problem as you. I saw your problem, but still don't
understand why it works like that. Could you do me a favour to have a look
and tell me your understanding about *SetRange()*. 
   Thank you, and I look forward to hearing from you.
    Best regards,

Hello,


I have a problem with vtkStreamTracer.


Here is the code:


```

def generate_streamline(source_file, dest_file, axis, resolution=1):
    reader = vtk.vtkXMLImageDataReader()
    reader.SetFileName(source_file)
    reader.GetPointDataArraySelection().DisableArray('density')
    reader.Update()
    extent = reader.GetOutput().GetExtent()
    center = [np.mean(extent[0:2]), np.mean(extent[2:4]), np.mean(extent[4:6])]

    seeds = vtk.vtkPointSource()
    seeds.SetCenter(center)
    seeds.SetRadius(10.5)
    seeds.SetNumberOfPoints(100)
    seeds.Update()

    streamTracer = vtk.vtkStreamTracer()
    streamTracer.SetInterpolatorTypeToDataSetPointLocator()
    streamTracer.SetInputData(reader.GetOutputDataObject(0))
    streamTracer.SetSourceData(seeds.GetOutputDataObject(0))
    streamTracer.SetIntegratorTypeToRungeKutta45()
    streamTracer.SetMaximumPropagation(104)
    streamTracer.SetInitialIntegrationStep(0.2)
    streamTracer.SetMaximumIntegrationStep(0.5)
    streamTracer.SetIntegrationDirectionToBoth()
    streamTracer.SetStartPosition(center)
    streamTracer.SurfaceStreamlinesOn()
    streamTracer.Update()

    print(streamTracer.GetOutputDataObject(0))

```

The output is:
```

Hi

I am trying to create point cloud visualizer and editor and need to combine
three functions below:
- area picking inherited by rubber band picking interactor
- point picking inherited by trackball camera
- get to know of rotation given by trackball actor

How can I combine these three interactor classes?

Thanks.

Depending on settings, there are a few ways it can be computed.
vtkCamera::ComputeProjectionTransform is the starting point for tracking
down the specifics:

WarningThis algorithm is a very simple implementation that overlooks some
potential complexities. For example, if a vertex is multiply connected,
meaning that it is used by multiple distinct polylines, then the extra
topological constraints are ignored. This can produce less than optimal
results.

Is above warning code for  "crash at following lines"

  void Remove(vtkIdType vertexIdx)

in vtkDecimatePolylineFilter.cxx class vtkDecimatePolylineFilter::Polyline

?

I have multiple distinct polylines housed in vtkPolyData.  I can seem to do
batch mode operations, *not that this documented anywhere mind you*,  with
vtkParametricFunctionSource for splines and vtkSmoothPolyDataFilter for
smoothing.... decimation errr not so much.

The goal which seems to work for some vtk classes (
vtkParametricFunctionSource  and vtkSmoothPolyDataFilter ) but not for
others (vtkDecimatePolylineFilter) is to house a network of lines connected
in a graph, but not a simple graph node to node, which do not represent
some geometry say like a circle or polygon, but rather a network of paths
and nodes.  Goal was to put in pipeline with optional decimation, smoothing
or spline, but then goes the crash at decimation.

Just what are those "potential complexities" and the bit about overlooking
say like bad memory access.  next has a pointer, but prev pointer not so
much (NULL).  Hey what about overlooking error checking and null pointers.
Clearly it seems to be overlooking that.

Subject: [vtkusers] Point Smoothing
Message-ID: <1540995648660-0.post@n5.nabble.com>

Hi
I am working on a point cloud renderer with Qt which OpenGLWidget has been
promoted as custom class and all VTK related codes are included. That seems
working stable.

When I rendered point cloud, they seems as square and so I tried to apply 
GetRenderWindow()->PointSmoothingOn();
in the beginning of the load events.

Points seems as circle till I resize or move the window.
How can I keep them always circle?

Subject: [vtkusers] Writing a pvts file properly
Message-ID: <1541018487717-0.post@n5.nabble.com>

Hi all,

I'm trying to understand how to write a .pvts file properly. I have 50x50x50
point data on a cubic, uniform grid. The data is split into four different
processors, each having a slice (in the z direction) of the grid point
positions and point values (pressure, velocity, density). There is no
overlap between the datasets of each processor.

I can write .vts files using the vtk library just fine. Paraview reads each
one of them just fine. The vts file of the first processor "output_0.vts"
looks like this:

<?xml version="1.0"?>
<VTKFile type="StructuredGrid" version="0.1" byte_order="LittleEndian"
compressor="vtkZLibDataCompressor">
   <StructuredGrid WholeExtent="0 49 0 49 0 11">
     <Piece Extent="0 49 0 49 0 11">
       <PointData>
         <DataArray type="Float64" Name="Density" format="appended"
RangeMin="0.001178"             RangeMax="0.001178"                
offset="0"                   />
         <DataArray type="Float64" Name="u" format="appended"
RangeMin="-9960.5735066"        RangeMax="9960.5735066"         o   
ffset="916"                 />
         <DataArray type="Float64" Name="v" format="appended"
RangeMin="-9960.5735066"        RangeMax="9960.5735066"         o   
ffset="113492"              />
         <DataArray type="Float64" Name="w" format="appended" RangeMin="0"                   
RangeMax="0"                    o    ffset="229092"              />
         <DataArray type="Float64" Name="Pressure" format="appended"
RangeMin="955826.16262"         RangeMax="1043825.5135"            
offset="229684"              />
       </PointData>
       <CellData>
       </CellData>
       <Points>
         <DataArray type="Float64" Name="Points" NumberOfComponents="3"
format="appended" RangeMin="0.10882796185"        Range   
Max="8.9148192623"         offset="265460"              />
       </Points>
     </Piece>
   </StructuredGrid>
   <AppendedData encoding="base64">
   </AppendedData>
</VTKFile>

now I'd like to write the corresponding pvts file. What I have so far is the
following:

<?xml version="1.0"?>
<VTKFile type="PStructuredGrid" version="0.1" byte_order="LittleEndian"
compressor="vtkZLibDataCompressor">
  <PStructuredGrid WholeExtent="0 49 0 49 0 49" GhostLevel="1">
    <PPoints>
      <DataArray type="Float64" Name="Points" NumberOfComponents="3"/>
    </PPoints>
    <PPointData>
      <DataArray type="Float64" Name="Density"/>
      <DataArray type="Float64" Name="u"/>
      <DataArray type="Float64" Name="v"/>
      <DataArray type="Float64" Name="w"/>
      <DataArray type="Float64" Name="Pressure"/>
    </PPointData>
    <Piece Extent="0 49 0 49 0 11" Source="output_0.vts"/>
    <Piece Extent="0 49 0 49 12 23" Source="output_1.vts"/>
    <Piece Extent="0 49 0 49 24 35" Source="output_2.vts"/>
    <Piece Extent="0 49 0 49 36 49" Source="output_3.vts"/>
  </PStructuredGrid>
</VTKFile>

When I open this in paraview I get the error message:
"vtkXMLPStructuredGridReader (0x896d9c0): No available piece provides data
for the following extents:
    0 49  0 49  11 12
    0 49  0 49  23 24
    0 49  0 49  35 36
The UpdateExtent cannot be filled."

It's basically complaining that I don't provide data for the extents
separating the pieces... Do I have to or is there some modification to the
file I can make so that it works out? The data from two neighboring
processors do not overlap (is that a crime for paraview/vtk?) but the points
values at the boundary are one Mesh_spacing away from each other. 

Best
