[comp.graphics] Question about convex polyhedral solids

Imhotep@cup.portal.com (STEVE CARL MAHER) (11/07/88)

I have a question about closed convel polyhedral solids.  If I am given two 
arbitrary solids whose surface consists of convex polyhedra, and if the solids
themselves are convex, does anyone know of an algorithm for finding a separatin
plane?  All the algorithms that I have been able to devise are of order
N^3.  It seems to me that the convexity is such a strong restriction that
an algorithm of lower order should exist.  

Thanks in advance for any possible help with this.
