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 headed by [Hang Si](https://github.com/sihang0592) during his affiliation with [Weierstrass Institute for Applied Analysis and Stochastics, (WIAS) Berlin](https://www.wias-berlin.de/software/tetgen).
|
|
|
|
The primary development repository is [https://codeberg.org/TetGen/TetGen](https://codeberg.org/TetGen/TetGen). Please
|
|
open any issues in this repository. The github repository [https://github.com/TetGen/Tetgen](https://github.com/TetGen/Tetgen)
|
|
is a mirror of the codeberg repository.
|
|
|
|
This repository provides the source code of the most recent versions of TetGen.
|

## 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.
|
|
|
|
Details about the extension of this dual licensing scheme for future versions of TetGen will be announced in due time.
