I think he was talking about using the object pattern in MegaPOV/POV 3.5 
to either generate the boxes or do the testing itself.

Seems like an awful lot of boxes to test against. A heirarchial oct-tree 
arrangement would be a lot more efficient, or even testing directly 
against the object.
Why are you coding for individual objects? It seems like doing things 
the hard way. Is this a patch or external program?
