At the bottom level, a vertex stores a point and a provides access to one of its incident face through a void * pointer.

Types

Vertex_base::Point
	Must be the same as the point type Gt::Point defined by the geometric traits class of the triangulation.

Creation

Vertex_base v;
	Default constructor.
Vertex_base v ( Point p);
	Construct a vertex embedded in point p.
Vertex_base v ( Point p, void* f);
	Construct a vertex embedded in point p and pointing on face *f.

Access Functions

Point	v.point ()	Returns the point.
void*	v.face ()	A pointer to an incident face.

Setting

void	v.set_point ( Point p)
		Sets the point.
void	v.set_face ( void* f)
		Sets the incident face.

Checking

bool

v.is_valid ()

To perform any required geometrical test on a vertex.
