Result intersect ( const Plane3D< T, EPPlane, NPPlane > & plane, const LineSegment3D< T, PPRay > & lineSegment, T & t )

related

Find the intersection of a plane and line segment by their parameter t on the ray.

Parameters

plane	[in] the plane
lineSegment	[in] the line segment
t	[out] the parameter of the intersection point > tMin.
tMin	[in] the minimum t that may be returned as valid intersection.

Returns

• rNone no intersections found t is not assigned.
• rOne exactly one intersection found t represents it.
• rInfinite infinite many intersections found (segment is coincident with plane), t is not assigned.
• rInvalid plane or lineSegment is invalid, no intersection. t is not assigned.
