CGAL 5.3 - 3D Boolean Operations on Nef Polyhedra
CGAL::Nef_polyhedron_3< Nef_polyhedronTraits_3, Nef_polyhedronItems_3 >::SFace Class Reference

#include <CGAL/Nef_polyhedron_3.h>


template<class Nef_polyhedronTraits_3, class Nef_polyhedronItems_3 = CGAL::Default_items<Nef_polyhedronTraits_3> class Nef_polyhedronMarks = bool>
class CGAL::Nef_polyhedron_3< Nef_polyhedronTraits_3, Nef_polyhedronItems_3 >::SFace

An sface is described by its boundaries.

Figures figureNef3HalfedgeIncidences and figureNef3HalfloopIncidences illustrate the incidences of an sface. 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.


There is no need for a user to create a SFace explicitly. The class Nef_polyhedron_3<Traits> manages the needed sfaces internally.
