<p>A curve generator of the present invention has a group of registers (1-4), a group of files (5-7), an operator (9), a comparator (13) and a sequencer (11). The curve generator interpolates for a curve in the vicinity of a plurality of designated control points (A-D), for example, a Bezier curve or a Spline curve, by calculating coordinate values of middle points between the control points on the basis of coordinate values of said control points (A-D). The curve generator of the present invention realizes, by means of an exclusive hardware, the processing of an algorithm of generating the curve and, therefore, is capable of generating the curve at extremely high speed. <IMAGE></p> |
