CGAL::Nef_polyhedron_S2<Traits>::SVertex

Definition

The figure on page \icon illustrate 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.

#include <CGAL/Nef_polyhedron_S2.h>

Types

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

Nef_polyhedron_S2<Traits>::SVertex::Mark
	type of mark.
Nef_polyhedron_S2<Traits>::SVertex::Sphere_point
	sphere point type stored in SVertex.
Nef_polyhedron_S2<Traits>::SVertex::SVertex_const_handle
	const handle to SVertex.
Nef_polyhedron_S2<Traits>::SVertex::SHalfedge_const_handle
	const handle to SHalfedge.
Nef_polyhedron_S2<Traits>::SVertex::SFace_const_handle
	const handle to 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.

Operations

Mark	e.mark ()	the mark of e .
Sphere_point	e.point ()	the sphere point of e .
bool	e.is_isolated ()	returns |true| if e has no adjacent sedges.
SVertex_const_handle
	e.twin ()	the twin of e .
SHalfedge_const_handle
	e.out_sedge ()	the first out sedege of e .
SFace_const_handle	e.incident_sface ()
		the incident sface of e .
