I'm trying to slap randomly distributed objects onto an isosurface in the 
shape of a lumpy torus.  The only tool that I've found to help is the 
trace(OBJECT_IDENTIFIER, A, B, [VECTOR_IDENTIFIER]) function.  
Unfortunately, it only returns points on the "outside" part of the torus 
(ie. not inside the donut hole).  Is there any way I can make it trace to 
the entire torus?  Is there another function or macro that will do the 
job?

I can put the objects in a regular torus through some inventive vector 
math, but conquering the lumpiness is beyond my abilities, it seems.
