Abstract: An algorithm on the bi-hyperbola approximation of cubic Bezier curves is given in this pa-per. It aims at the smoothness of the resulting curve.The precision is higher and the speed is faster than that with arcs approximation[2]. It can save a half drawing information for a given precision.
