PolyhedronItems_3::Vertex Concept Reference

## Definition

The `PolyhedronItems_3::Vertex` concept refines the `HalfedgeDSItems::Vertex` concept. This concept adds the requirement for the support of the geometry.

Refines:
  `HalfedgeDSItems::Vertex`

## Types in PolyhedronItems_3::Vertex_wrapper<Refs,Traits>::Vertex

typedef unspecified_type | Point
| point type stored in vertices. More...
typedef unspecified_type | Supports_vertex_point
| \(\equiv\) `CGAL::Tag_true`. A point is always required.

## Creation

| Vertex ()
| Default constructor.
| Vertex (Point)
| Constructor from a point.

## Operations

Point & | point ()
const Point & | point () const

## Member Typedef Documentation

typedef unspecified_type PolyhedronItems_3::Vertex::Point

point type stored in vertices.

A `HalfedgeDS has no dimension, so this type is named Point` and not `Point_3`
