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

#include <CGAL/Nef_polyhedron_S2.h>

Definition

Figures figureNefS2SVertexIncidences and figureNefS2SHalfloopIncidences illustrate the incidences of an sface.

An sface is described by its boundaries. An entry item to each boundary cycle can be accessed using the iterator range (sface_cycles_begin()/sface_cycles_end()). Additionally, Nef_polyhedron_S2 provides the macro CGAL_forall_sface_cylces_of. The iterators are of type SFace_cycle_const_iterator and represent either a shalfedge, a shalfloop, or a svertex.

Creation

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