Function Documentation

template<typename Kernel >
CGAL::Point_2<Kernel> CGAL::circumcenter ( const CGAL::Point_2< Kernel > &  p,
const CGAL::Point_2< Kernel > &  q 
)

compute the center of the smallest circle passing through the points p and q.

Note: this is the same as CGAL::midpoint(p, q) but is provided for homogeneity.

#include <CGAL/Kernel/global_functions.h>

template<typename Kernel >
CGAL::Point_2<Kernel> CGAL::circumcenter ( const CGAL::Point_2< Kernel > &  p,
const CGAL::Point_2< Kernel > &  q,
const CGAL::Point_2< Kernel > &  r 
)

compute the center of the circle passing through the points p, q, and r.

Precondition
p, q, and r are not collinear.

#include <CGAL/Kernel/global_functions.h>

template<typename Kernel >
CGAL::Point_2<Kernel> CGAL::circumcenter ( const CGAL::Triangle_2< Kernel > &  t)

compute the center of the circle passing through the vertices of t.

Precondition
t is not degenerate.

#include <CGAL/Kernel/global_functions.h>

template<typename Kernel >
CGAL::Point_3<Kernel> CGAL::circumcenter ( const CGAL::Point_3< Kernel > &  p,
const CGAL::Point_3< Kernel > &  q 
)

template<typename Kernel >
CGAL::Point_3<Kernel> CGAL::circumcenter ( const CGAL::Point_3< Kernel > &  p,
const CGAL::Point_3< Kernel > &  q,
const CGAL::Point_3< Kernel > &  r 
)

compute the center of the circle passing through the points p, q, and r.

Precondition
