[vtkusers] Rigid Volume Rotation (transformation)

[Marius S Giurgi]

Hi, all VTK gurus.

I was hoping someone could point out for me what are the VTK classes to 
use to do a rigid volume rotation. (obviously I'm new to VTK). I know 
there must be a VTK (cubic and nearest neighbor interpolation) rigid 
rotation somewhere in the VTK library but I can't find one. I came 
across a paper on "fast rigid volume transformation" recently where the 
author was referencing a VTK equivalent of such transformation, but 
without giving any specifics on what vtk class (method) does such a 
transformation. I'd really appreciate it if someone could give me some 
hints .

thanks,
marius
