Hi 

Problem: Given a set of xyz coordinates for an object how does 
one find the set of points that are on the surface ?. 
Alternatively the set of polygons that describe the surface of 
an irregular object.

I would appreciate if someone sent pesudocode. Pointer to references
will suffice otherwise. C/FORTRAN code would be manna!!
Thanks
