What is TetGen?

TetGen is a program to generate tetrahedral meshes of any 3D polyhedral domains. TetGen generates exact constrained Delaunay tetrahedralizations, boundary conforming Delaunay meshes, and Voronoi partitions. The following pictures respectively illustrate a 3D polyhedral domain (left), a boundary conforming Delaunay tetrahedral mesh (middle), and its dual - a Voronoi partition (right).
