摘要
应用扩展的三次均匀 B样条曲线 ,给出了逼近椭圆曲线的高精确逼近方法 ,论证了该方法精度 ,扩展了多项式参数曲线的应用。文中给出了逼近曲线的图例。
By using the extensive cubic uniform B-spline curves, a high accurate approximation method for ellipse curves is presented in this paper. We proved the approximating precision of the method and then the application of polynomial curves is extended. Some approximating curves are given.
