WebBeziers, B-Splines and Nurbs - University of Cambridge WebPlotting shows the closed spline: Closed NURBS. Going from B-Splines to NURBS means the addition of weights and non-uniform knots. Weights are straightforward since they correspond directly to points. As for knots, an unclosed NURBS spline requires n + degree + 1 knots, where n is the number of points.

In computer graphics, a T-spline is a mathematical model for defining freeform surfaces. A T-spline surface is a type of surface defined by a network of control points where a row of control points is allowed to terminate without traversing the entire surface. The control net at a terminated row resembles the letter "T". Modeling surfaces with T-splines can reduce the number of control points in comparison to NUR…
