Non-Uniform Rational B-Splines, are mathematical representations of 3-D geometry that can accurately describe any shape from a simple 2-D line, circle, arc, or curve to the most complex 3-D organic free-form surface or solid.

See this overview of NURBS geometry for more information.

A NURBS curve is defined by four things: degree, control points, knots, and an evaluation rule.

## Aggregation

A joined collection of NURBS Curves (and perhaps other kinds of curves) is a Polycurve
