Detailed Description

A ray is a half-line P(t) = mOrig + mDir * t, with 0 <= t <= +infinity.

Member Function Documentation

Parameters

point	can be NULL
distance	can be NULL

int CShapeRay::IntersectPlane	(	const Plane *	plane,
		Vector3 *	point,
		float *	distance
	)		const

Returns: : 1:intersected -1:The plane is parallel to the ray; -2:The plane is facing away from the ray so no intersection occurs. -3:The intersection occurs behind the ray's origin.

std::pair< bool, float > CShapeRay::intersects	(	const CShapeAABB &	box,
		const Matrix4 *	world = `NULL`
	)		const

Tests whether this ray intersects the given box.

Parameters

box	aabb box
world	a rotation transform applied to AABB. This can be NULL.

Returns: A pair structure where the first element indicates whether an intersection occurs, and if true, the second element will indicate the distance along the ray at which it intersects.
