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.
