Non-Uniform Rational B-Spline. This is the most general form of a B-spline commonly being used by CAD programs. Non-Uniform allows uneven spacing of the B-spline knots for more control over the shape of the curve or surface. Rational allows for exact representation of conic shapes and simpler perspective projections.

Non-Uniform Rational B-Spline - modelling technique.

(Non-Uniform Rational B-spline). A parametric surface that can be trimmed with nonuniform rational B-spline curves and piecewise linear curves.

Nonuniform Rational B-Spline: a type of spline that can represent more complex shapes than a Bezier spline.

an acronym for "Non Uniform Rational B-Spline", it is a mathematical model commonly used for generating and representing curves and surfaces

Non-Uniform Rational B-Spline - a mathematical definition for a surface element used in CAD modeling.

(n) Acronym for nonuniform rational B-spline, a type of free-form curve that uses rational B-splines and allows for a weighting value at each point on the surface. Because NURBS can also precisely describe conic surfaces, they are gaining popularity in tasks previously done with other types of 3-D modelers.
