## ConvexHullPolyhedronHalfedge_3

### Definition

The requirements of the halfedge type required for the polyhedron built by the function convex_hull_3.

### Has Models

CGAL::Polyhedron_3<Traits>::Halfedge

### Creation

ConvexHullPolyhedronHalfedge_3 h;
| default constructor.

### Operations

Halfedge_handle | h.opposite () | the opposite halfedge.
Halfedge_handle | h.next () | the next halfedge around the facet.
Halfedge_handle | h.prev () | the previous halfedge around the facet.
bool | h.is_border () const
|  | is true if h is a border halfedge.
Halfedge_around_facet_circulator
| h.facet_begin () | circulator of halfedges around the facet (counterclockwise).
Vertex_handle | h.vertex () | the incident vertex of h.
Facet_handle | h.facet () | the incident facet of h. If h is a border halfedge the result is default construction of the handle.
