Difference (from prior major revision) (minor diff)

Changed: 1c1

Nonuniform Rational B-Splines.

Nonuniform Rational B-Splines are a mathematical tool for the definition of geometric shapes.

Changed: 3c3

A tool for the definition of geometry.

Used extensively in the CAD? industry and more widely in computing for 3D geometry generation and modelling because of their accuracy, flexibility, commonality of mathematical form for both standard geometric shapes and free-form shapes, fast algorithms, invariance under affine and perspective transformations, and that they are generalizations of non-rational B-splines? and both types of [Bezier curves]? and surfaces.
