Member Function Documentation

intersectAABB()

bool U4DEngine::U4DRay::intersectAABB	(	U4DAABB &	uAABB,
		U4DPoint3n &	uIntersectionPoint,
		float &	uIntersectionTime
	)

test intersection with an AABB Box

Parameters

uAABB	AABB to test intersection
uIntersectionPoint	ray intersection point
uIntersectionTime	ray intersection time

Returns

true if the ray intersects the AABB

intersectPlane()

bool U4DEngine::U4DRay::intersectPlane	(	U4DPlane &	uPlane,
		U4DPoint3n &	uIntersectionPoint,
		float &	uIntersectionTime
	)

tests intersection with a plane

Parameters

uPlane	Plane to test intersection
uIntersectionPoint	ray intersection point
uIntersectionTime	ray intersection time

Returns

true if the ray intersects the plane

intersectTriangle()

bool U4DEngine::U4DRay::intersectTriangle	(	U4DTriangle &	uTriangle,
		U4DPoint3n &	uIntersectionPoint,
		float &	uIntersectionTime
	)

test intersection with a 3D triangle

Parameters

uTriangle	3D Triangle to test intersection
uIntersectionPoint	ray intersection point
uIntersectionTime	ray intersection time

Returns

true if the ray intersects the triangle

operator=()

U4DRay & U4DEngine::U4DRay::operator=

(

const U4DRay &

a

)

Copy constructor for the Ray.

Parameters

a	3D ray to copy

Returns

Returns a copy of the 3D ray
