Definition

The class Alpha_shape_vertex_base_3 is the default model for the concept AlphaShapeVertex_3.

Template Parameters
Traitsis the geometric traits class that is provided to the Alpha_shape_3 class.
Vbmust be a vertex base class adapted to the type of triangulation that is being used. By default, it is instantiated with Triangulation_vertex_base_3<Traits>, which is appropriate for basic alpha shapes.
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_3 for more details. The default value is Tag_false.
WeightedTagis used only if ExactAlphaComparisonTag is Tag_true. It must be Tag_true if the underlying triangulation of the alpha shape to be used is a regular triangulation and Tag_false otherwise. The default is Tag_false.
Is Model Of:
