FaceGraph Concept Reference
Concepts

Definition

The concept FaceGraph refines the concept HalfedgeGraph. It adds the requirements for a graph to explicitly maintain faces described by halfedges, to provide access from a face to an incident halfedge, and to provide access from a halfedge to its incident face.

Refines:
HalfedgeGraph
Has Models:

CGAL::Polyhedron_3

CGAL::Surface_mesh

CGAL::Linear_cell_complex_for_combinatorial_map
