Definition

The class Alpha_shape_vertex_base_2 is the default model for the concept AlphaShapeVertex_2.

Template Parameters
Traitshas to be a model of AlphaShapeTraits_2.
Vbhas to be a model of TriangulationVertexBase_2 (or RegularTriangulationVertexBase_2) if Alpha_shape_vertex_base_2 is intended to be used with an alpha-shape class based on a Delaunay_triangulation_2 (or a Regular_triangulation_2).
ExactAlphaComparisonTagis a tag that, when set to Tag_true, triggers exact comparisons between alpha values. See the description provided in the documentation of Alpha_shape_2 for more details. The default value is Tag_false.
Is Model Of:
AlphaShapeVertex_2
