Function Documentation

approximate_angle() [1/2]

template<typename Kernel >

Kernel::FT CGAL::approximate_angle	(	const CGAL::Point_3< Kernel > &	p,
		const CGAL::Point_3< Kernel > &	q,
		const CGAL::Point_3< Kernel > &	r
	)

#include <CGAL/Kernel/global_functions.h>

returns an approximation of the angle between p-q and r-q.

The angle is given in degrees.

Precondition

p != q and r != q.

approximate_angle() [2/2]

template<typename Kernel >

Kernel::FT CGAL::approximate_angle	(	const CGAL::Vector_3< Kernel > &	u,
		const CGAL::Vector_3< Kernel > &	v
	)

#include <CGAL/Kernel/global_functions.h>

returns an approximation of the angle between u and v.

The angle is given in degrees.

Precondition

u and v are not equal to the null vector.
