#include <CGAL/Fuzzy_iso_box.h>

Definition

The class Fuzzy_iso_box implements fuzzy d-dimensional iso boxes.

A fuzzy iso box with fuzziness value ϵ has as outer approximation a box dilated, and as inner approximation a box eroded by a d-dim square with side length ϵ.

Parameters

Expects for the template argument a model of the concept SearchTraits, for example CGAL::Search_traits_2<CGAL::Simple_cartesian<double> >.

Is Model Of:
FuzzyQueryItem

Examples:

Types

typedef Traits::Point_d Point_d
 Point type.
 
typedef Traits::FT FT
 Number type.
 

Creation

 Fuzzy_iso_box (Point_d p, Point_d q, FT epsilon=FT(0), Traits t=Traits())
 Constructs a fuzzy iso box specified by the minimal iso box containing p and q and fuzziness value epsilon. More...
 
 Fuzzy_iso_box (Traits::Base::Point_d p, Traits::Base::Point_d q, FT epsilon=FT(0), Traits t=Traits())
 Constructs a fuzzy iso box specified by the minimal iso box containing p and q and fuzziness value epsilon. More...
 

Operations

bool contains (Point_d p) const
 test whether the fuzzy iso box contains p.
 
bool inner_range_intersects (const Kd_tree_rectangle< FT > &rectangle) const
 test whether the inner box intersects the rectangle associated with a node of a tree.
 
bool outer_range_contains (const Kd_tree_rectangle< FT > &rectangle) const
 test whether the outer box encloses the rectangle associated with a node of a tree.
 

Constructor & Destructor Documentation

template<typename Traits >
CGAL::Fuzzy_iso_box< Traits >::Fuzzy_iso_box ( Point_d  p,
Point_d  q,
FT  epsilon = FT(0),
Traits  t = Traits() 
)

Constructs a fuzzy iso box specified by the minimal iso box containing p and q and fuzziness value epsilon.

Precondition
p must be lexicographically smaller than q.
template<typename Traits >
CGAL::Fuzzy_iso_box< Traits >::Fuzzy_iso_box ( Traits::Base::Point_d  p,
Traits::Base::Point_d  q,
FT  epsilon = FT(0),
Traits  t = Traits() 
)

Constructs a fuzzy iso box specified by the minimal iso box containing p and q and fuzziness value epsilon.

Attention
Only available in case Traits is Search_traits_adapter<Key,PointPropertyMap,BaseTraits>.
Precondition
p must be lexicographically smaller than q.
