#include <CGAL/Min_sphere_of_spheres_d_traits_d.h>

Definition

The class Min_sphere_of_spheres_d_traits_d<K,FT,Dim,UseSqrt,Algorithm> is a model for concept MinSphereOfSpheresTraits.

It uses the CGAL type Point_d to represent circles.

Is Model Of:

MinSphereOfSpheresTraits

Template Parameters

K	is a model for Kernel.
FT	is a number type, which fulfills the requirements of type FT of concept MinSphereOfSpheresTraits: It must be either double or float, or an exact number type.
UseSqrt	fulfills the requirements of type Use_square_roots of concept MinSphereOfSpheresTraits: It must be either Tag_true or Tag_false and it defaults to Tag_false.
Algorithm	fulfills the requirements of type Algorithm of concept MinSphereOfSpheresTraits: It must be either Default_algorithm, LP_algorithm or Farthest_first_heuristic, and it defaults to Default_algorithm.

Examples:

Min_sphere_of_spheres_d/min_sphere_of_spheres_d_d.cpp.

Constants
typedef unspecified_type	D
	is the constant Dim.

Types
In addition to the types required by the concept MinSphereOfSpheresTraits, this model also defines the types Radius and Point. Here's the complete list of defined types:
typedef unspecified_type	FT
typedef unspecified_type	Use_square_roots
typedef unspecified_type	Algorithm
typedef unspecified_type	Radius
	is a typedef to the template parameter FT
typedef unspecified_type	Point
	is a typedef to K::Point_d.
typedef unspecified_type	Sphere
	is a typedef to std::pair<Point,Radius>.
typedef unspecified_type	Cartesian_const_iterator
	is a typedef to K::Cartesian_const_iterator_d.

Access Functions
The class provides the access functions required by the concept MinSphereOfSpheresTraits; they simply map to the corresponding routines of class K::Point_d:
FT	radius (const Sphere &s)
	maps to s.second.
Cartesian_const_iterator	center_cartesian_begin (const Sphere &s)
	maps to s.first.cartesian_begin().
