I need help. Do you know such a library for 3D triangulation - CGAL? How to get from it the order of joining the vertices to enter into your variable? Found nothing on the official site. Thanks!

I know nothing of CGAL, but have you tried TetGen?

  • $\begingroup$ actually, I don't understand how to use it (what functions to call for triangulation) $\endgroup$ Commented Nov 18, 2021 at 16:37
  • $\begingroup$ Read its documentation? (wias-berlin.de/software/tetgen/1.5/doc/manual/index.html). Seems pretty decent to me. $\endgroup$

  • $\begingroup$ Yeah. I read this, but also cant understand. )) $\endgroup$ Commented Nov 18, 2021 at 16:55
  • $\begingroup$ If you google with "tetgen examples", there are lots of hits. I don't use tets in my code, but hexahedra, so I can't help you use tetgen, I only knew that it existed. $\endgroup$
