I am aware of the difficulties, but there don't seem to be many 
alternatives...as far as I can tell, you would only be able to use the 
vertex information and would get a field of points, losing all 
"connectivity" information. POV does not use any algorithms like this 
and they would probably be difficult and slow to implement in the scene 
description language. As I mentioned, it is possible to test rays 
against a point field instead...this may be a better idea, but would 
require implementing a point field primitive for POV.
