Definition

The concept FixedWeightedAlphaShapeTraits_3 describes the requirements for the geometric traits class of the underlying regular triangulation of a weighted alpha shape with fixed alpha value.

Refines:: RegularTriangulationTraits_3

In addition to the requirements described in the concept RegularTriangulationTraits_3, the geometric traits class of a regular triangulation plugged in a weighted alpha shape with fixed alpha value provides the following.

◆ Compare_weighted_squared_radius_3

typedef unspecified_type FixedWeightedAlphaShapeTraits_3::Compare_weighted_squared_radius_3

An object constructor able to compare the squared radius of the smallest sphere orthogonal to either four, three, two or one weighted point(s) to a given value of alpha.

It provides:

Comparison_result operator()(Weighted_point_3 ,Weighted_point_3 ,Weighted_point_3 ,Weighted_point_3 )
Comparison_result operator()(Weighted_point_3 ,Weighted_point_3 ,Weighted_point_3 )
Comparison_result operator()(Weighted_point_3 ,Weighted_point_3 )
Comparison_result operator()(Weighted_point_3 )
