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.

A partial specialization must be provided for CGAL::graph_has_property for each internal property map available.

Associated Types
boost::graph_traits<FaceGraph>::face_descriptor

A face descriptor corresponds to a unique face in an abstract graph instance. A face descriptor must be DefaultConstructible, Assignable, EqualityComparable, and Hashable.
