If it's TIN generation from 3D points that you want, it's hard to beat Shewchuk's library called 'Triangle', as mentioned by Traian below.
For the related subject of triangulation of polygons, i've got a summary of all known open-source options at http://vterrain.org/Implementation/Libs/triangulate.html It turns out that 'Triangle' is great for that too. -Ben > -----Original Message----- > From: Traian Stanev > Sent: Monday, March 02, 2009 8:34 AM > Subject: [OSGeo-Discuss] RE: Open source TIN code? > > > Not sure about the BSD licensing part, but here are some cool TIN > triangulators which are open source. > > > This one (Streaming Delaunay) has BSD-like license, but may be overkill for > what you need: > > http://www.cs.unc.edu/~isenburg/sd/ > > > This one (FIST) has nebulous licensing (different for commercial and non- > commercial uses): > > http://www.cosy.sbg.ac.at/~held/projects/triang/triang.html > > > And finally, this one is pretty good, but also has unclear licensing: > > http://www.cs.cmu.edu/~quake/triangle.html > > > > Traian > > > > > -----Original Message----- > From: Michael P.
