Does anybody have C source for a program to compute the CONVEX HULL of a set of points in 3D? INPUT : a set of points (Xi,Yi,Zi). OUTPUT: the polygons forming the convex hull surface OR the half-spaces defined by the facets of the hull. A fast algorithm would be nice, but brute force would be OK since the point sets will not be very large. Thanks for any help. andy dean dean@cis.ohio-state.edu
