Non-uniform rational basis spline (NURBS) is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces. It offers great flexibility and precision for handling both analytic (surfaces defined by common mathematical formulae) and modeled shapes. They can be efficiently handled by the computer programs and yet allow for easy human interaction. NURBS surfaces can represent simple geometrical shapes in a compact form.

Depending on the type of user interface, editing can be realized via an element’s control points, which are most obvious and common for Bézier curves, or via higher level tools such as spline modeling or hierarchical editing.

This hat can be made into a beanie, Tam or slouch. I hope that you will discover your favorite style, then make one for you and one for a friend.
