CGAL 4.10 - 3D Alpha Shapes
|
The concept FixedAlphaShapeTraits_3
describes the requirements for the geometric traits class of the underlying Delaunay triangulation of a basic alpha shape with a fixed value alpha.
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.

typedef unspecified_type | Comparison_result |
CGAL::Comparison_result or Uncertain<CGAL::Comparison_result> | |
typedef unspecified_type | 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. More... | |

Access Functions | |
Compare_squared_radius_3 | compare_squared_radius_3_object () |
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)
