Scape

Fast polygonal approximation of a height field by a Triangulated Irregular Network (TIN). Greedy insertion algorithm inserts the point with greatest error at each step.

In C++. Papers and source code available from the Web page. Also has a lot of pointers to other GIS sites.

By Michael Garland, a student of Paul Heckbert at CMU.
