NURBS curve

A NURBS curve is a primitive representing a 3D NURBS curve. These curves are smooth mathematical spline interpolations of a set of control points. A NURBS curve is parametrised along a U coordinate, varying between 0 and 1.

A NURBS curve has following notable properties:

• control points: a list of 3D vectors representing the 3D coordinates of the points that define the curves's mathematical spline function.
• order: a positive integer defining the number of nearby control points that influence any given point on the curve. Practically: the higher the number, the smoother the curve. Order 2 effectively turns the curve into a polyline connecting the control points with straight line segments.
