Detailed Description

template<class T>
class al::Plane< T >

A plane in Euclidean space

Member Function Documentation

from3Points()

template<class T >

Plane< T > & al::Plane< T >::from3Points	(	const Vec3 &	v1,
		const Vec3 &	v2,
		const Vec3 &	v3
	)

Set from three points lying on the plane.

The normal is computed according to a right-handed coordinate system. For left-handed, swap the first and last vertices.
