CGAL::Nef_polyhedron_3<Traits>::SFace
Definition
Figures 29.10
and 29.10
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.

Types
The following types are the same as in Nef_polyhedron_3<Traits>.
|
Nef_polyhedron_3<Traits>::SFace::Mark
|
|
type of mark.
|
|
|
Nef_polyhedron_3<Traits>::SFace::Object_list
|
|
list of Object handles.
|
|
|
Nef_polyhedron_3<Traits>::SFace::Vertex_const_handle
|
|
const handle to Vertex.
|
|
Nef_polyhedron_3<Traits>::SFace::Volume_const_handle
|
|
const handle to Volume.
|
|
Nef_polyhedron_3<Traits>::SFace::SFace_const_handle
|
|
const handle to SFace.
|
|
Nef_polyhedron_3<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_3<Traits> manages the needed sfaces internally.
Operations
|
Mark
|
sf.mark () const
|
the mark of sf .
|
|
|
Vertex_const_handle
|
sf.center_vertex () const
|
the center vertex of the sphere map sf belongs to.
|
|
|
Volume_const_handle
|
sf.volume () const
|
the volume that corresponds to sf in the 3D incidence structure.
|
|
|
SFace_cycle_const_iterator
|
sf.sface_cycle_begin () const
|
iterator over the entries to all sface cycles of sf .
|
|
|
SFace_cycle_const_iterator
|
sf.sface_cycle_end () const
|
past-the-end iterator.
