Detailed Description

Defines plane.

Constructor & Destructor Documentation

Plane	(	const Vec3 &	p1,
		const Vec3 &	p2,
		const Vec3 &	p3
	)

Create plane from tree point.

The point #1 which's in the plane. The point #2 which's in the plane. The point #3 which's in the plane.

Plane	(	const Vec3 &	normal,
		float	dist
	)

Create plane from normal and dist.

The normal vector of the plane. The distance from the origin along the normal.

Plane	(	const Vec3 &	normal,
		const Vec3 &	point
	)

Create plane from normal and a point on plane.

The normal vector of the plane. The point which's in the plane.
