[vtkusers] multiple volumes rendering

[eugen]

Hi!

I've already asked about overlapping multiple volumes rendering (Sat Jun 9  
10:24:33 EDT 2007), but got no answer, so this is just a second, but  
shorter try:-)

Why is it that complicated to introduce overlapping multiple volumes  
rendering in vtk, that no one has done it before?
Where to start if one want to add overlapping multiple volumes rendering  
(with 3D texture mapping) to vtk?

Maybe I'm missing something and vtk already is capable of overlapping  
multiple volumes rendering...

Please, can someone give me a hint?


Thanks it advance!!!
