[vtkusers] Volume Rendering - Using different scalars for opacity and color transfer function

[Taha Ceritli]

Hi,

I think you need to use vtkVolumeRayCastFunction instead of
vtkVolumeRayCastCompositeFunction as follows:

CastFunction = vtkVolumeRayCastFunction()
volumeMapper.SetVolumeRayCastFunction(CastFunction)

It's not appropriate to send a composite function to
raycastcompositefunction. Let me know if it works or not.

Good luck paule :)
