In computer graphics, a smooth, mathematically-defined curve or line defined by two endpoints (called anchor points) and two control points (called Bézier control points) in a region adjacent to the curve. Since the Bézier curves are defined mathematically, rather than as bitmaps, it is possible to print illustrations composed of them at as high a resolution as the output device is capable of. They are also processed by the computer much more rapidly. Bézier curves are used to create graphics in CAD programs, as well as vector-based illustration programs such as Adobe Illustrator. See also Encapsulated PostScript. The concept of the Bézier curve was invented by Paul Bézier to aid in the design of Renault automobiles. "Bézier" is pronounced "BEH-zee-ay."
