NURBS Curve
A nonuniform rational B-Spline curve defined by
where
is the order, 
are the B-Spline basis functions, 
are control points, andthe weight 
of is the last ordinate of the homogeneous point 
. These curves areclosed under perspective transformations and can represent Conic Sections exactly. See also B-Spline, Bézier Curve, NURBS Surface
