CGAL 4.12 - 3D Triangulations
TriangulationVertexBase_3 Concept Reference

## Definition

The vertex base used by the geometric triangulation must store a point. We list here the additional requirements compared to a vertex base usable for the triangulation data structure.

Refines:
TriangulationDSVertexBase_3
Has Models:
TriangulationCellBase_3

## Types

typedef unspecified_type Point
Must be the same as the point type TriangulationTraits_3::Point_3 defined by the geometric traits class of the triangulation.

## Creation

TriangulationVertexBase_3 (const Point &p)
Constructs a vertex whose geometric embedding is point p.

TriangulationVertexBase_3 (const Point &p, Cell_handle c)
Constructs a vertex embedding the point p and pointing to cell c.

## Access Functions

Point point () const
Returns the point.

## Setting

void set_point (Point p)
Sets the point.

## I/O

istream & operator>> (istream &is, TriangulationVertexBase_3 &v)
Inputs the non-combinatorial information given by the vertex: the point and other possible information.

ostream & operator<< (ostream &os, const TriangulationVertexBase_3 &v)
Outputs the non-combinatorial information given by the vertex: the point and other possible information.
