Triangulations for boundary recovery. (a)-(d) obtained from INRIA's mesh database ( https://www.rocq.inria.fr/gamma/gamma/download/download.php). (e)-(f) obtained from the CAVS Sims Center at MSU.

  • (a) Mohne
  • (b) Anc101
  • (c) Thru-maze
  • (d) Mech-shell
  • (e) Submesh1
  • (f) Nozzle
Evaluation results on boundary recovery. CDT3D is compared with the state-of-the-art open-source technology TetGen v1.5.0. #Spts is the number of Steiner points. The experiments were performed on a Linux desktop machine with an Intel Core 17-2600 CPU @3.40GHz, and 16 GB RAM.
