template<typename _tType , typename _tVecType , typename _tPlaneType >

static LSE_INLINE LSBOOL LSE_CALL lsp::CIntersect::LineSegPlane	(	const _tVecType &	_vStart,
		const _tVecType &	_vEnd,
		const _tPlaneType &	_pPlane,
		_tType &	_fT,
		_tVecType &	_vRet
	)		[inline, static]

If the given line segment intersects the given plane, true is returned and the point where the line segment intersects the plane is returned.

Parameters:

_vStart	The starting point of the line segment to test for intersection against the given plane.
_vEnd	The end point of the line segment to test for intersection against the given plane.
_pPlane	The plane against which to test for intersection.
_fT	The returned intersection T value, if any.
_vRet	The returned intersection point, if any.

Returns:

Returns true if the line segment intersects the plane.

template<typename _tType , typename _tVecType , typename _tPlaneType >

static LSE_INLINE LSVOID LSE_CALL lsp::CIntersect::LineSegPlaneFast	(	const _tVecType &	_vStart,
		const _tVecType &	_vEnd,
		const _tPlaneType &	_pPlane,
		_tVecType &	_vRet
	)		[inline, static]

Assumes the line segment is known to intersect the given plane and returns the point of intersection.

Parameters:

_vStart	The starting point of the line segment to test for intersection against the given plane.
_vEnd	The end point of the line segment to test for intersection against the given plane.
_pPlane	The plane against which to test for intersection.
_vRet	The returned intersection point.

template<typename _tType , typename _tPlaneType , typename _tVecType >

static LSE_INLINE LSBOOL LSE_CALL lsp::CIntersect::ThreePlanes	(	const _tPlaneType &	_pP0,
		const _tPlaneType &	_pP1,
		const _tPlaneType &	_pP2,
		_tVecType &	_vRet
	)		[inline, static]

Gets the intersection point of 3 planes if there is one. If not, false is returned.

Parameters:

_pP0	Plane 1.
_pP1	Plane 2.
_pP2	Plane 3.
_vRet	The returned intersection point, valid only if true is returned.

Returns:

Returns true if the 3 planes intersect at a single point.

template<typename _tType , typename _tPlaneType , typename _tRayType >

static LSE_INLINE LSBOOL LSE_CALL lsp::CIntersect::TwoPlanes	(	const _tPlaneType &	_pP0,
		const _tPlaneType &	_pP1,
		_tRayType &	_rRay
	)		[inline, static]

If the given planes intersect, the ray defining the intersection is returned. Planes must be normalized.

Parameters:

_pP0	Plane 1.
_pP1	Plane 2.
_rRay	The return ray.

Returns:

Returns true if the 2 planes intersect.
