The Be´zier representation of curves is commonly used in computer graphics. A different, less advanced way of representing a curve is that of using a polyline, i.e., a sequence of short straight lines. This paper describes a “curve builder” that converts a polyline into a sequence of one or more Be´zier curves.Part of the method is based on mathematical groundwork by Pat Beirne of Corel Systems Corporation, with extensions by the authors.The project was implemented in APL and could not otherwise have been completed with the resources and time available.
