摘要
本文给出了有理四次Ｂéｚｉｅｒ曲线精确地表示圆弧的充分必要条件，并证明了其能表示任意圆弧但不可能表示整个圆周．
In this paper, the necessary and sufficient condition and the sufficient condition for rational cubic Bezier curves representation of circular arcs are given. The similar results for rational cubic B-spline curves and Ball curves are presented.These algorithms are useful in shape design, numerical control and particularly in geometric modeling.
