Use sample :

Creation with two dimensions, a length and three Vector3D : Vector3D origin = new Vector3D(1.0, 6.0, -2.0); Vector3D direction = new Vector3D(6.0, -3.0, -1.0); double length = 2.0; LineSegment segment = new LineSegment(origin, direction, length); Distance to a line : double distance = segment.distanceTo(line);

Concurrency :

immutable
