I don't think there are any public implementations of Delaunay triangulation in pure Python, though, if that's what you want. You can easily find more sample code in other languages by googling. http://svn.scipy.org/svn/scipy/branches/newscipy/Lib/sandbox/delaunay/ -- Robert Kern rkern(a)ucsd.edu "In the fields of hell where the grass grows high Are the graves of dreams allowed to die." -- Richard Harter

I want to see some in Python because it is hard for me to figure out using python to do Fortune's sweeping line algorithm. Is python is not good in doing that kind of computation or some other reason? Thanks a lot for all of your responses!!!

I know someone once mentioned that they tried writing one of the Delaunay triangulation algorithms in pure Python and abandoned it for being unusably slow. -- Robert Kern rkern(a)ucsd.edu "In the fields of hell where the grass grows high Are the graves of dreams allowed to die." -- Richard Harter |
