[vtkusers] Bug in VTK 4.0 with vtkVolumeRayCastCompositeFunction???

[Sepp^ Huber]

Hello all,

I've written a program with VTK 3.2 that does some volume rendering on
scalar data. In the program the user can choose between
vtkVolumeRayCastCompositeFunction and vtkVolumeRayCastMIPFunction for visualization. After I upgraded
to VTK 4.0 I get some strange behavior. If I use vtkVolumeRayCastMIPFunction
then everything is fine and e.g a cube is rendered. On the other hand if I use
vtkVolumeRayCastCompositeFunction I would expect to receive a transparent
cube but as it looks I only get some kind of cutplane through my data which can
be rotated using the interactor. As I haven't changed my code this behavior
is a little strange. Does anybody know how to fix this or what might be the
reason?

Thanks in advance
Sepp
