Class

CGAL::Alpha_shape_vertex_base_3<Traits,Vb,ExactAlphaComparisonTag,WeightedTag>

Definition

The class Alpha_shape_vertex_base_3<Traits,Vb,ExactAlphaComparisonTag,WeightedTag> is the default model for the concept AlphaShapeVertex_3.

The class has four parameters : the traits class Traits which provides the type for the points or the weighted points. The second parameter Vb is a base class instantiated by default with CGAL::Triangulation_vertex_base_3<Traits>. The third parameter ExactAlphaComparisonTag is a tag that, when set to CGAL::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 CGAL::Tag_false. The fourth parameter WeightedTag is used only if ExactAlphaComparisonTag is CGAL::Tag_true. It must be CGAL::Tag_true if the underlying triangulation of the alpha shape to be used is a regular triangulation and CGAL::Tag_false otherwise. The default is CGAL::Tag_false.
