CGAL::Nef_polyhedron_S2< Traits >::SVertex Class Reference

#include <CGAL/Nef_polyhedron_S2.h>

Definition

Figure figureNefS2SVertexIncidences illustrates the incidence of a svertex on a sphere map.

The member function out_sedge() returns the first outgoing shalfedge, and incident_sface() returns the incident sface.

Creation

There is no need for a user to create a SVertex explicitly. The class Nef_polyhedron_S2<Traits> manages the needed svertices internally.
