Before implementing something, it would be good to find out just what the
intended use is.  The reason I say this is that "ray tracing" need not
result in images at all.  We rely heavily upon ray-tracing of solid models
here for computation having nothing to do with producing images.  I think
that, as you assumed, the fellow probably really wants some sort of
"lighting model" program, not ray tracing as such.
