Detailed Description

A 2D plane class

Represents plane with a normal and offset such that x on the plane satisfy dot(normal,x) = offset.

Member Function Documentation

int Math3D::Plane2D::allIntersections	(	const Plane2D &	p,
		Vector2 &	pt
	)		const

returns the dimension of the intersection of the 2 planes.
if 0, they don't intersect, pt is intersection "point at infinty".
1, it's a point returned in pt
2, the planes are identical
