Non-uniform rational basis spline (NURBS) is a mathematical model using basis splines (B-splines) that is commonly used in computer graphics for representing curves and surfaces. It offers great flexibility and precision for handling both analytic (defined by common mathematical formulae) and modeled … Meer weergeven Before computers, designs were drawn by hand on paper with various drafting tools. Rulers were used for straight lines, compasses for circles, and protractors for angles. But many shapes, such as the freeform curve of … Meer weergeven A number of transformations can be applied to a NURBS object. For instance, if some curve is defined using a certain degree and N control points, the same curve can be expressed using the same degree and N+1 control points. In the process a … Meer weergeven • Spline • Bézier surface • de Boor's algorithm • Triangle mesh Meer weergeven A surface under construction, e.g. the hull of a motor yacht, is usually composed of several NURBS surfaces known as NURBS patches (or just patches).

It offers … WebOne of the more powerful features of QuickDraw 3D is its ability to work with curves and surfaces of arbitrary shape. The mathematical model it uses to represent them is known as NURB, for nonuniform rational B-splines. The NURB model is flexible and powerful, but for those unfamiliar with the mathematics, it can appear dauntingly complex.
