ABSTRACT:
A curve generator has a group of registers, a group of files, an operator, a comparator and a sequencer. The curve generator interpolates for a curve in the vicinity of a plurality of designated control points, 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. The curve generator realizes, an exclusive hardware, from an algorithm for generating the curve and, therefore, is capable of generating the curve at extremely high speed.
