[vtkusers] Converting triangulated data to voxels

[Mathieu Bosi]

Hi Santosh

I'm new too to vtk so I couldn't suggest a way to accomplish your task using
this library.
Anyway reading your post I remembered having just recently read an article
about trimesh->voxels, I think you may find it useful:

   http://kurtm.flipcode.com/cgi-bin/fcj.cgi?category=1&page=1

the article of interest is in the bottom of the page and is called "Voxel
Mesh Creation and Rendering".

Hope this helps =)
