#include <CGAL/Min_sphere_of_points_d_traits_3.h>

Definition

The class Min_sphere_of_points_d_traits_3<K,FT,UseSqrt,Algorithm> is a model for concept MinSphereOfSpheresTraits.

It uses the CGAL type Point_3 to represent spheres.

Template Parameters

K	must be 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 is by default `CGAL::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 is by default `CGAL::Default_algorithm`.

Constants
typedef unspecified_type	D
	is the constant 3, i.e. the dimension of \( \mathbb{R}^3\).

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_3`.

typedef unspecified_type	Sphere
	is a typedef to `Point`.

typedef unspecified_type	Cartesian_const_iterator
	is a typedef to `K::Cartesian_const_iterator_3`.

Access Functions
The class provides the access functions required by the concept `MinSphereOfSpheresTraits`; they simply map to the corresponding routines of class `K::Point_3`:
FT	radius (const Sphere &s)
	returns `0`.

Cartesian_const_iterator	center_cartesian_begin (const Sphere &s)
	maps to `s.first.cartesian_begin()`.
