- Open MITK-Data/3D+t-Heart
- Switch on volume visualization 💣
- Crash 💥
Segmentation fault occurs in vtkAOSDataArrayTemplate::GetTypedComponent(vtkIdType tupleIdx, int comp) after accessing the buffer.
Crash only occurs with the DICOM 3D+t image which also causes trouble in T24767 and T24766. Seems to work with all other 3d+t images in MITKData. Volume visualization works for the image if it is exported to .nrrd first.
We found out that volume visualization works as expected when following the described steps:
- Close rendering display
- Open MITK-Data/3D+t-Heart (rendering display is opened automatically)
- Switch on volume visualization
- No crash :)
We couldn't find out the difference between the initial rendering display and the second rendering display so far.
The issue still occurs on both Windows and Linux systems. The transfer function widget seems to be initialized correctly. The last MITK method called before diving into VTK internals mentioned above is VtkMapper::MitkRenderVolumetricGeometry.
