Function Documentation

angle() [1/3]

template<typename Kernel >

Angle CGAL::angle	(	const CGAL::Point_2< Kernel > &	p,
		const CGAL::Point_2< Kernel > &	q,
		const CGAL::Point_2< Kernel > &	r
	)

#include <CGAL/Kernel/global_functions.h>

returns CGAL::OBTUSE, CGAL::RIGHT or CGAL::ACUTE depending on the angle formed by the three points p, q, r (q being the vertex of the angle).

The returned value is the same as angle(p - q, r - q).

angle() [2/3]

template<typename Kernel >

Angle CGAL::angle	(	const CGAL::Point_2< Kernel > &	p,
		const CGAL::Point_2< Kernel > &	q,
		const CGAL::Point_2< Kernel > &	r,
		const CGAL::Point_2< Kernel > &	s
	)

#include <CGAL/Kernel/global_functions.h>

returns CGAL::OBTUSE, CGAL::RIGHT or CGAL::ACUTE depending on the angle formed by the two vectors pq, rs.

The returned value is the same as angle(q - p, s - r).

angle() [3/3]

template<typename Kernel >

Angle CGAL::angle	(	const CGAL::Point_3< Kernel > &	p,
		const CGAL::Point_3< Kernel > &	q,
		const CGAL::Point_3< Kernel > &	r,
		const CGAL::Point_3< Kernel > &	s
	)

#include <CGAL/Kernel/global_functions.h>

returns CGAL::OBTUSE, CGAL::RIGHT or CGAL::ACUTE depending on the angle formed by the two vectors pq, rs.

The returned value is the same as angle(q - p, s - r).
