TetGen is a quality tetrahedral mesh generator and 3-dimensional Delaunay triangulator. Based on the the-state-of-the-art algorithms for Delaunay tetrahedralization and mesh generation, this program has been specifically designed to fulfill the task of automatically generating high quality tetrahedral meshes, which are suitable for scientific computing using numerical methods such as finite element and finite volume methods. The purpose of this document is to give a brief explanation of the problems solved by TetGen and to provide a detailed user's documentation. In this document, the user will learn how to create tetrahedral meshes using TetGen's input files and command line switches. In the following section, the programming interface of TetGen for calling TetGen from another program is explained. Various examples are given to simplify the ``getting started''.
