[vtkusers] multiple volume rendering

[Ilinca, Radu]

Hello ! I am still a newbie in VTK :(. I want to perform  a standard 
raycasting using the vtkVolumeRayCastCompositeFunction class. The 
dataset is mapped around the vtkVolumeRayCastMapper. It works. However, 
I want to have 2 volumes and perform the raycasting using the same 
vtkVolumeRayCastCompositeFunction. So...how do I load the 2 volumes in 
the same mapper ???? Which class should I modify / use..which functions 
should I overrride..please give me some starter ideas !!  I tried so far 
to modify the vtkVolumeRayCastMapper but it didn't worked :(

Thanks,
