Definition

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

Template Parameters
Traitsmust be a geometric traits class which provides the type for the points or the weighted points.
Vbmust be a vertex base class instantiated by default with CGAL::Triangulation_vertex_base_3<Traits>.
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:
AlphaShapeVertex_3
