In addition to the requirements described in the concept DelaunayTriangulationTraits_3, the geometric traits class of a Delaunay triangulation plugged in a basic alpha shape with fixed alpha value provides the following.
FixedAlphaShapeTraits_3::Comparison_result | |
CGAL::Comparison_result or Uncertain<CGAL::Comparison_result>
| |
FixedAlphaShapeTraits_3::Compare_squared_radius_3 | |
An object constructor able to compare the squared radius of the smallest circumscribing sphere of either four, three, two or one point(s) with a given value of alpha. It provides: Comparison_result operator()(Point_3,Point_3,Point_3,Point_3) Comparison_result operator()(Point_3,Point_3,Point_3) Comparison_result operator()(Point_3,Point_3) Comparison_result operator()(Point_3)
