NURB - Computer Definition
(NonUniform Rational B-spline) A type of b-spline that is very flexible. NURB curves can represent any shape from a straight line to a circle or ellipse with very little data. They can also be used for guiding animation paths, for approximating data and for controlling the shapes of 3D surfaces. NURBs are known for their ability to control the smoothness of a curve. See spline and b-spline.
