Non-Uniform Rational B-Spline (Non-Uniform Rational Basis Spline): a mathematical model used in computer graphics for generating and representing curves and surfaces
A NURBS surface is obtained as the tensor product of two NURBS curves, thus using two independent parameters u and v (with indices i and j respectively): Piegl and Tiller, chapter 4, sec. 4 : with : as rational basis functions. Source: Internet
Included as part of Spatial's suite of 3D modeling development technologies, 3D Deformable Modeling uses local and global editing features that allow for the easy creation and manipulation of free-form B-spline and NURBS curves and surfaces. Source: Internet
By evaluating a NURBS at various values of the parameters, the curve can be traced through space; likewise, by evaluating a NURBS surface at various values of the two parameters, the surface can be represented in Cartesian space. Source: Internet
Like B-splines, NURBS control points determine the shape of the curve. Source: Internet
Most applications support solid modeling with boundary representation (B-Rep) and NURBS geometry, and enable the same to be published in a variety of formats. Source: Internet
The knot vector is a sequence of parameter values that determines where and how the control points affect the NURBS curve. Source: Internet
