+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 (@sihang0592)
+at [Weierstrass Institute for Applied Analysis and Stochastics, (WIAS) Berlin](https://www.wias-berlin.de).
+This repository provides the source code of the most recent versions of TetGen as repository releases:
+
+- [v1.4.3, 2011](https://github.com/TetGen/TetGen/archive/refs/tags/v1.4.3.tar.gz): [MIT licensed with noncommercial clause](https://raw.githubusercontent.com/TetGen/TetGen/refs/tags/v1.4.3/LICENSE)
+- [v1.5.0, 2013](https://github.com/TetGen/TetGen/archive/refs/tags/v1.5.0.tar.gz): [AGPLv3](https://www.gnu.org/licenses/agpl-3.0.html) licensed
+- [v1.5.1, 2018](https://github.com/TetGen/TetGen/archive/refs/tags/v1.5.1.tar.gz): [AGPLv3](https://www.gnu.org/licenses/agpl-3.0.html) licensed, recommended as most stable version
+- [v1.6.0, 2020](https://github.com/TetGen/TetGen/archive/refs/tags/v1.6.0.tar.gz): [AGPLv3](https://www.gnu.org/licenses/agpl-3.0.html) licensed, latest version with some rough edges
+
+
+In addition, it is planned to publish future versions of TetGen via this repository.
+
+## Documentation
+- Manuals are available in https://github.com/TetGen/Manuals.
+- A technical paper about TetGen is available at [Hang Si, "TetGen, a Delaunay-Based Quality Tetrahedral Mesh Generator". ACM Trans. on Mathematical Software. 41 (2), 2015](http://doi.acm.org/10.1145/2629697)
+
+
+## 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 affiliation of Hang Si, the contination of this dual licensing scheme for
+future versions of TetGen is uncertain.
