WeightedAlphaShapeTraits_3 Concept Reference

Definition

The concept WeightedAlphaShapeTraits_3 describes the requirements for the geometric traits class of the underlying regular triangulation of a weighted alpha shape.

Refines

RegularTriangulationTraits_3 if the underlying triangulation of the alpha shape is a regular triangulation
