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.

Is Model Of:
MinSphereOfSpheresTraits
Template Parameters
Kmust be a model for Kernel.
FTis 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.
UseSqrtfulfills 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.
Algorithmfulfills 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().
