Function Documentation

Intersection2d math::intersect	(	const Vector2d &	a1,
		const Vector2d &	a2,
		const Vector2d &	b1,
		const Vector2d &	b2
	)

Calculate the intersection between 2 segments.

The first segment is A:[a1, a2] The second segment is B:[b1, b2]

If the segments are parallel, kInfinity is returned
