In this paper, a G(1), C(1), C(2) PH-spline is employed as an approximation for a given Bézier curve within error bound and further renders offset which can be regarded as an approximate offset to the Bézier curve. The errors between PH-spline and the Bézier curve, the offset to PH-spline and the offset to the given Bézier curve are also estimated. A new algorithm for constructing offset to the Bézier curve is proposed.
本文采用G(1)、C(1)、C(2) PH样条在误差范围内逼近给定的贝塞尔曲线,并进一步生成偏移量,该偏移量可视为贝塞尔曲线的近似偏移量。同时还估计了PH样条与贝塞尔曲线之间的误差、PH样条的偏移量与给定贝塞尔曲线的偏移量之间的误差。提出了一种构造贝塞尔曲线偏移量的新算法。
