Vertex of a Polyhedral Surface

Definition

A vertex optionally stores a point and a reference to an incident halfedge that points to the vertex. Type tags as defined in Polyhedron_3 indicate whether these member functions are supported. Figure  depicts the relationship between a halfedge and its incident halfedges, vertices, and facets.

Types

Vertex defines the same types as Polyhedron_3 except the traits class.
