[Insight-users] bug in vtk6 itkvtkglue itkhead

[Jose Ignacio Prieto]

Hi all, I have a bug but I'm not sure if its vtk or itk fault.
I load a 4D image with itk, then use a pipeline similar to

itkImageExtractionRegionFilter->SetInput(reader->GetOutput)
( I set correctly the index and see the 3D image, the time frame I choose)

ImageToVTKImageFilter->SetInput(itkImageExtractionRegionFilter->GetOutput)

vtkGPUVolumeRayCastMapper->SetInput(itkImageToVTKImageFilter->GetOutput)

vtkOpenGLRenderer->SetInput(vtkGPUVolumeRayCastMapper->GetOutput)

The code above works nice in VTK 5.10 and ITK head. The problem is when I
try to run the same using the VTK head version. The ray cast mapper works
ok and I can see the selected 3D volume, but I have a callback to change
the fframe and It doesn't work now. The callback changes the index in the
extraction filter and then calls qvtkwidget ->render

On vtk6 I am connecting the vtkopenglrenderer and raycastmapper using
SetInputData(xxxxxx->GetOutput) instead of SetInput->(xxx->GetOutput) I was
using on vtk5. Is that the problem??

Thank you very much
