Non-Uniform Rational Basis Spline (NURBS)

Definition - What does Non-Uniform Rational Basis Spline (NURBS) mean?

A non-uniform rational basis spline (NURBS) is a type of mathematical function used to create two-dimensional and three-dimensional objects. NURBS is used in computer graphics as a way to construct shapes and models mathematically.

Techopedia explains Non-Uniform Rational Basis Spline (NURBS)

In general, a spline is a numerical construct that is put together using polynomials. Polynomials are mathematical expressions of a variable equation that can be plotted on a graph. As a particular type of spline, a NURBS is considered "non-uniform" in that certain sections of the spline can be changed relative to other sections. It is also considered "rational" in that elements of the design can be weighted. NURBS helps designers to work with curves and contours in digital and mathematically constructed designs. For example, a NURBS equation could help to support digital or virtual coordinates for a 3-D model of a human or other character, or a complex object to be rendered in a computer graphics system.
