I would be very interested in any programs which can translate 3-D object
descriptions (either from CSG or a boundary representation which can
handle curves) into a polgonal approximation of the boundary
representation of the same object.  Actually, any input description
technique sufficiently powerful enough to easily describe complex
objects would be fine.  The important thing is that the output be a
polygonal description of the boundary of the object.  The types of
objects I would like to describe easily are primarily assembly parts.  I
am familiar with the PADL-2 system which uses CSG to describe such
parts, but as far as I know, it does not handle polygonal approximation.

Any help (pointers or code) would be appreciated.

Thanks,
