CGAL 4.7 - 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.
