Concept

Splitter

Definition

The concept Splitter defines the requirements for a function object class implementing a splitting rule.

Has Models

CGAL::Fair<Traits, SpatialSeparator>,
CGAL::Median_of_rectangle<Traits, SpatialSeparator>,
CGAL::Median_of_max_spread<Traits, SpatialSeparator>,
CGAL::Midpoint_of_rectangle<Traits, SpatialSeparator>,
CGAL::Midpoint_of_max_spread<Traits, SpatialSeparator>,
CGAL::Sliding_fair<Traits, SpatialSeparator>,
CGAL::Sliding_midpoint<Traits, SpatialSeparator>.

Types

Splitter::FT
Number type.


Splitter::Separator
Separator.


Splitter::Container
Typedef to an instantiation of CGAL::Point_container<Traits>.

The parameters aspect_ratio and bucket_size define the way in which k-d tree is constructed.

Operations

FT s.aspect_ratio () const Returns the maximal ratio between the largest and smallest side of a cell allowed for fair splitting.

unsigned int s.bucket_size () const Returns the bucket size of the leaf nodes.

void s ( Separator& sep , Container& c0 , Container& c1 ) const
Sets up sep and splits points of c0 into c0 and c1 using sep. Container c0 should contain at least two points and c1 must be empty.
