AdvancingFrontSurfaceReconstructionTraits_3 Concept Reference

Definition

The concept AdvancingFrontSurfaceReconstructionTraits_3 describes the requirements for the the geometric traits of the class CGAL::Delaunay_triangulation_3 used in the class CGAL::Advancing_front_surface_reconstruction. It defines the geometric objects (points, segments...) forming the triangulation together with a few geometric predicates and constructions on these objects.
