[vtkusers] Get output from ray tracer for every voxel

[KS Jothybasu]

Hi all,

I have a vtkImageDATA. Now I want to ray trace from a distance, let's say
from 50 cm from the image data surface(I think this should be set y the
camera).

While tracing the ray, I want to get the voxels it travels through and the
length traveled in each of those voxels.

Is there any way to control the number of rays, we generate.


Thanks

Jothy
