CGAL 5.1.2 - 2D Periodic Hyperbolic Triangulations
|
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. | |
