https://github.com/MarcoAttene/CDT is used in a 2023 SIGGRAPH Asia paper. According to that paper, it is about 8.6% more robust than TetGen (https://github.com/libigl/tetgen).

Like TetGen, this code has GPL/LGPL licenses. I have asked Marco Attene whether he could re-license it as Apache 2.0 or BSD 3.

https://github.com/FabienPean/VegaFEM/blob/main/libraries/mesher/tetMesher.h is a re-implementation of TetGen with compatible licenses with Drake.

Nobody updated Vega FEM (https://viterbi-web.usc.edu/~jbarbic/vega/) at the University of Southern California for nearly five years. The latest release was v4.0 in 2018 (https://viterbi-web.usc.edu/~jbarbic/vega/download.html).

https://github.com/FabienPean/VegaFEM is an unofficial fork of Vega FEM 4.0.
