If you are working with isosurfaces (and if you don't care about
shadows), then you can calculate how much a light source illuminates
a point on the surface by using functions in SDL. (I.e. you don't
need to patch POV-Ray to do this.)
I once used such a technique to make a few simple images.
Some of them can be found in this thread:

It should also be possible to do something similar with meshes
made up of (small) triangles.
