The idea here is that it would provide a class that holds the result of the triangulation. Yes, it would use the existing delaunay code by default, and hopefully optionally use the not-as-good-a-license code the Robert Kern put in SciPy. In the future, I hope we can find a robust and well-licensed code -- I may be able to release some in-house code of ours for that some day. > 2) Separate the storage of and creation of contour sets so that you > can create your own. > 3) tricontour and tricontourf functions to contour a Triangulation. > 4) Python utility plotting functions for a Triangulation (triplot, > tripcolor, etc). > 5) Simple wrappers for 3 and 4 so you can just pass in the points and > the Triangulation is created for you behind the scenes. yup -- that all sounds great! > I am happy to make a start with this; wonderful! > no doubt it will take me a while.

Maybe this can be revisited when I'm done. hopefully, there still doesn't appear to be a really good delaunay code with a flexible license out there -- pity. > Do you want it all in one go, or one unit of functionality at a time > (my preference)?

Most of those folks are on this list, to, but may not be following this thread. By the way, it sounds like your contouring code is in C++ -- is that important? I don't expect it should be that computationally expensive, though maybe hard to vectorize -- C++ does make portability harder, though there's a bunch in MPL already. If I was starting from scratch, I'd use Cython, if pure Python didn't cut it. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
