Bisection Algorithms for Approximating Quadratic Bézier Curves by G1 Biarc Splines
二次Bézier曲线的双圆弧样条插值二分算法

In CNC,it is often required to approximate Bézier curves by G1 arc splines with as few arc segments as possible. A bisection algorithm for approximating a quadratic Bézier curve by a G1 Biarc spline is presented. The new method reduces the number of the segments in the resultant arc spline under the given error tolerance.Some numerical results are given to illustrate the efficiency of the algorithm.
