摘要
给出了有理五次Bézier曲线精确表示0<2θ<2π(θ为圆心角)的圆弧及整圆的充要条件,加以了证明并给出了图例..
We give necessary and sufficient conditions for rational pentagonal Bézier curves representation of circular arcs whose circular angle are more than zero and less than 2n and whole circle. The proofs are also given and examples are presented.
