Non-uniform rational B-spline - WikipediaA NURBS curve. (See also: the animated creation of a NURBS spline.) A NURBS surface Non-uniform rational basis spline (NURBS) is a mathematical model using basis splines (B-splines) that is commonly used in computer graphics for representing curves and surfaces. It offers great flexibility and precision for handling both analytic (defined by common mathematical formulae) and modeled shapes. It is
