◆ circumcenter() [1/8]

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

#include <CGAL/Kernel/global_functions.h>

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.

◆ circumcenter() [2/8]

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

)

#include <CGAL/Kernel/global_functions.h>

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

Precondition
p, q, and r are not collinear.
