WebDetailed Description. interface to a 2.5d polygon of arbitrary complexity. The DM polygon object can handle arbitrary nested polygons (often called multi part polygons). The implementation is based on the CGAL nef polygons, a 2d polyhedron representation. Hence, positive regions (=part of the polygon) may contain an arbitrary number of negative ... WebSep 8, 2024 · Added the function CGAL::regularize_face_selection_borders () , which uses this alpha expansion graphcut to regularize the borders of a selected faces on a triangle mesh. Added the function CGAL::set_triangulation_ids () , which must be used to initialize vertex, edge, and face indices of a triangulation meant to be used with BGL algorithms.
