By Martin Held. Copes with polygons with holes and degeneracies/self-intersections; based on repeatedly clipping ears. Source code on request.

Mesh generation in 2D and 3D on Unix and NT, and related software by Steven Vavasis.

J-D. Boissonnat et al.'s code for Delaunay meshing in 2 and 3 dimensions in C++.

C code for orientation and incircle tests using adaptive-precision floating-point arithmetic

Summary of major CG problems and implementations of their solutions

Two Java applets for editing polygons and point sets for input to computational geometry software.

Gmsh is a three-dimensional finite element mesh generator, primarily Delaunay, with built-in pre- and post-processing facilities. Gmsh is freely available for Windows and most UNIX platforms.

Open-source library for manipulating 3D triangular surface meshes. Delaunay triangulations, robust geometric predicates, robust boolean set operations on surfaces, surface refinement and coarsening, level-of-detail, k-d trees, volume and curvature, strips generation.

Jonathan Richard Shewchuk's Two-Dimensional Quality Mesh Generator and Delaunay Triangulator.

Produces commercial software that creates a surface model out of a pointcloud or polymesh [Balingen, Germany].

Fast and robust C++ code available under GNU license. Handles arbitrary dimensions, and has high numerical stability.

Lot of categories and links.

A collaborative effort to develop a robust, easy to use, and efficient C++ software library of geometric data structures and algorithms.

Computes convex hulls, Delaunay triangulations, Voronoi diagrams, half-space intersections about a point, furthest-site Delaunay triangulations, and furthest-site Voronoi diagrams. It runs in 2-d, 3-d, 4-d, and higher dimensions.
