Elliptical, hyperbolic and parabolic interpolation algorithms are introduced in this dissertation, which are based on central angle division. At the same time, the arc-length of ordinary and higher order ellipse are calculated.
介绍了基于圆心角时间分割的圆弧、椭圆、双曲线、抛物线等插补算法;同时推证了椭圆和高阶椭圆的弧长计算公式,并以此为基础介绍了等弧长法与等角度法。
