摘要

本文提出了一种用四次贝塞尔曲线逼近圆弧的方法。由于我们的四次近似误差函数的变化，我们的四次近似方法的误差比以前的四次近似方法小。我们的方法产生了一个封闭的误差形式，使得细分算法可用，并且曲率连续四次样条在等长圆弧下细分，直到误差小于公差。我们用一些数值例子来说明我们的方法。

CIRCLE APPROXIMATION BY QUARTIC G 2 SPLINE USING ALTERNATION OF ERROR FUNCTION

In this paper we present a method of circular arc approximation by quartic Bezier curve. Our quartic approximation method has a smaller error than previous quartic approximation methods due to the alternation of the error function of our quartic approximation. Our method yields a closed form of error so that subdivision algorithm is available, and curvaturecontinuous quartic spline under the subdivision of circular arc with equal-length until error is less than tolerance. We illustrate our method by some numerical examples.
