## ConvexHullPolyhedronFacet_3

### Definition

The requirements of the facet type of a polyhedron to be built by the function convex_hull_3.

### Has Models

CGAL::Polyhedron_3<Traits>::Facet

### Types

ConvexHullPolyhedronFacet_3::Plane
| plane equation type stored in facets.
ConvexHullPolyhedronFacet_3::Halfedge_handle
| handle to halfedge.
ConvexHullPolyhedronFacet_3::Halfedge_around_facet_circulator
| circulator of halfedges around a facet.

### Creation

ConvexHullPolyhedronFacet_3 f;
| default constructor.

### Operations

Plane& | f.plane ()
const Plane& | f.plane () const | plane equation.
Halfedge_handle | f.halfedge () | an incident halfedge that points to f.
Halfedge_around_facet_circulator
| f.facet_begin () | circulator of halfedges around the facet (counterclockwise).
