Problem with volume rendering
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I use vtkImageImport as a source for volume rendering. The first rendering is ok but when I change the values of the source and render again, there are black faces. Surprisingly, changing the source back to the original yields again a fine image. For details please refer to the attached sample program. This program creates a cuboid, sets the values and renders, then changes the values and renders again. One of the faces gets black although it should look the same as the other faces.
