CGAL 5.1.4 - 3D Alpha Shapes
|
The concept WeightedAlphaShapeTraits_3
describes the requirements for the geometric traits class of the underlying regular triangulation of a weighted alpha shape.
In addition to the requirements described in the concept RegularTriangulationTraits_3
, the geometric traits class of a regular triangulation plugged in a basic alpha shapes provides the following.
