when I use CGAL LSCM，I find there are some overlaps. there are some descriptions in CGAL doc. But I still want to use CGAL LSCM to achieve Mesh Parameterization，so what can I do to solve the problem.

Solution

  • The LSCM parameterization is not guaranteed to create a 1-to-1 mapping, so folds can indeed happen.

    You can attempt to improve the parameterization by using the class MVC_post_processor_3, which uses mean value coordinates to try and recover a 1-to-1 parameterization.
