Periodic_4HyperbolicTriangulationVertexBase_2 Concept Reference

Definition

Refines:

TriangulationVertexBase_2

A refinement of the concept TriangulationVertexBase_2 that adds an interface for hyperbolic translations.

For periodic hyperbolic triangulations, the vertex base class needs to temporarily store a hyperbolic translation during the insertion process. A boolean flag indicates whether the face stores a translation or not. The value of the flag is automatically set when storing or removing a translation.

Creation
	Periodic_4HyperbolicTriangulationVertexBase_2 ()
	Default constructor.
	Periodic_4HyperbolicTriangulationVertexBase_2 (const Point &p)
	Construct a vertex that stores the point p.
	Periodic_4HyperbolicTriangulationVertexBase_2 (const Point &p, Face_handle fh)
	Constructs a vertex that stores the point p and is incident to the face fh.
	Periodic_4HyperbolicTriangulationVertexBase_2 (const Face_handle &fh)
	Constructs a vertex that is incident to the face fh.

Hyperbolic translations API
void	set_translation (const Hyperbolic_translation &tr)
	Stores the translation tr in the vertex, and sets the translation flag to true.
Hyperbolic_translation	translation ()
	Returns the translation stored in the vertex.
void	clear_translation ()
	Removes the translation stored in the vertex, and sets the translation flag to false.
bool	get_translation_flag ()
	Returns the value of the translation flag.
