CGAL 5.5 - Advancing Front Surface Reconstruction
|
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.
