	Name	Description
	IsPoint	If true, the segment is a degenerated one (a point).
	Length	Gets the 3D segment length.
	LengthSquared	Gets the 3D segment length squared.
	MidPoint	Gets the 3D segment middle point.

	Name	Description
	AreCollinear	Returns true if the two segments are collinear.
	Clone	Creates a deep copy of this 3D segment.
	ClosestPointTo	Finds the point inside the segment that is closest to given point.
	ExtendTo	Extends (if necessary) the segment to the provided 3D point.
	Intersection	Overloaded. Gets the end points of the shortest segment perpendicular to two 3D segments, when it exists and is unique.
	IntersectWith	Overloaded. Intersects a 3D segment with a plane.
	IntersectWithInternal	Intersects the 3D segment with a plane. (For internal use only)
	IsInPlane	Checks if the 3D segment lays on the specified plane.
	IsOnAxis	Returns true if the segment lays on the axis defined by the 3D point center and the direction dir.
	PointAt	Evaluates a point on (infinite) segment.
	Project	Finds the point on the (infinite) line that is closest to given point.
	ToString	Converts this 3D segment to a human readable string.
