Actually, I know how to do that. What I really need to know is how to create interior points for a non-planar surface that will let me triangulate it into lots of little polygons, so the generated surface will look smooth. My specific application is a filled spinning globe. Currently I only show the outlines of continents; I would like to fill them in. I CAN triangulate the x,y,z of the outlines, but that's not enough. I need to introduce lots of interior points to the outlines so that small triangles will be produced. This is like a finite element analysis problem, but the FEA stuff I've seen is only good for planar polygons. Is there a method for generating interior points to a curved surface? Or do I compute the interior points in 2-D and then do the triangulation in 3-D? Pointers to references, ideas, or code (of course) would be most appreciated. -- Randy Schrickel randy@aplcomm.jhuapl.edu Johns Hopkins Applied Physics Lab Laurel, MD 20723 "Life goes on, long after the thrill of living has gone."
