TetGen is a mesh generator
developed by Hang Si which is designed to partition any 3D geometry into tetrahedrons by employing a form of Delaunay triangulation
whose algorithm was developed by the author.
TetGen has since been incorporated into other software packages such as Mathematica
and Gmsh
Mesh generation
Mesh generation is the practice of generating a polygonal or polyhedral mesh that approximates a geometric domain. The term "grid generation" is often used interchangeably. Typical uses are for rendering to a computer screen or for physical simulation such as finite element analysis or...

Delaunay triangulation
In mathematics and computational geometry, a Delaunay triangulation for a set P of points in a plane is a triangulation DT such that no point in P is inside the circumcircle of any triangle in DT. Delaunay triangulations maximize the minimum angle of all the angles of the triangles in the...
