Definition

template<typename Traits, typename Vb, typename ExactAlphaComparisonTag, typename WeightedTag>
class CGAL::Alpha_shape_vertex_base_3< Traits, Vb, ExactAlphaComparisonTag, WeightedTag >

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

Template Parameters

Traits	is the geometric traits class that is provided to the `Alpha_shape_3` class.
Vb	must 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.
ExactAlphaComparisonTag	is 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`.
WeightedTag	is 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`.
