◆ normal()

template<typename Kernel >
CGAL::Vector_3<Kernel> CGAL::normal ( const CGAL::Point_3< Kernel > &  p,
const CGAL::Point_3< Kernel > &  q,
const CGAL::Point_3< Kernel > &  r 
)

#include <CGAL/Kernel/global_functions.h>

computes the normal vector for the vectors q-p and r-p.

Precondition
The points p, q, and r must not be collinear.
