vtkGPUVolumeRayCastMapper and UserMatrix with negative determinant VTK 7.0
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When I have user matrix with negative determinant, vtkGPUVolumeRayCastMapper does not render correctly. I am not sure if this is an intended use case, it does however work with vtkFixedPointVolumeRayCastMapper and has worked with many (all?) of the volume mappers in vtk 6.*
The problems persists as of 0c5ee0e8
I'll attach a small program that shows the issue.
