CGAL::Nef_polyhedron_S2<Traits>::SFace

Definition

Figure  and figure  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.

#include <CGAL/Nef_polyhedron_S2.h>

Types

The following types are the same as in Nef_polyhedron_S2<Traits>.

Nef_polyhedron_S2<Traits>::SFace::Mark
	type of mark.
Nef_polyhedron_S2<Traits>::SFace::Object_list
	list of Object handles.
Nef_polyhedron_S2<Traits>::SFace::Vertex_const_handle
	const handle to Vertex.
Nef_polyhedron_S2<Traits>::SFace::Volume_const_handle
	const handle to Volume.
Nef_polyhedron_S2<Traits>::SFace::SFace_const_handle
	const handle to SFace.
Nef_polyhedron_S2<Traits>::SFace::SFace_cycle_const_iterator
	const iterator over the entries to all sface cycles of a sface.

Creation

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

Operations

Mark	sf.mark ()	the mark of sf .
SFace_cycle_const_iterator
	sf.sface_cycle_begin ()
		iterator over the entries to all sface cycles of sf .
SFace_cycle_const_iterator
	sf.sface_cycle_end ()
		past-the-end iterator.
