Hmm. Couldn't you do a limited sort of this. Like.. use a pattern with a 
known mathematical "shape", for the density, then computer where the ray 
should end up, based on a computed curve, based on that pattern? It 
wouldn't be perfect, obviously, but... for those patterns that could be 
calculated in such a manner, it could come close. Mind, this is just 
guessing...
