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.
TetGen versions up to v1.6.0 have been developed by Hang Si during his affiliation with Weierstrass Institute for Applied Analysis and Stochastics, (WIAS) Berlin.
This repository provides the source code of the most recent versions of TetGen. The following releases are provided:
- v1.4.3, 2011: MIT license with noncommercial clause
- v1.5.0, 2013: AGPLv3 license
- v1.5.1, 2018: AGPLv3 license recommended as most stable version
- v1.6.0, 2020: AGPLv3 license most recent version with some rough edges
It is planned to resume active development of TetGen and to publish future versions of TetGen via this repository.

Commercial licensing
TetGen versions developed at WIAS are distributed under a dual licensing scheme. As an alternative to the use of TetGen under the AGPLv3 license, consider the option to obtain a commercial license for a fee. These licenses are offered by the Weierstrass Institute for Applied Analysis and Stochastics (WIAS). As a rule, licenses are provided "as-is", unlimited in time for a one time fee. Please send corresponding requests to: tetgen at wias-berlin.de. Please do not forget to include some description of your company and the realm of its activities.
Due to the change of affilliation of Hang Si, the continuation of this dual licensing scheme for future versions of TetGen is uncertain.
