I'm looking for a simple (if exists) algorithm to find the Voronoi diagram for a set of points on the surface of a sphere. Source code would be great. I'm a Delphi man (yes, I know...), but I eat C-code too.
Here's a paper on spherical Voronoi diagrams.
Or if you grok Fortran (bleah!) there's this site.
