CGAL::Nef_polyhedron_S2<Traits>::SVertex

Figure 21.2 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.

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.

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

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 .
