椭圆的高质量、快速生成算法

更新时间：2026-09-14

本文给出一个等分角度为增量的绘椭圆算法，通过构造的几个表达式，减少了计算量，预处理后，计算每对绘图点只需９次减法．构造的表达式是直接对ｓｉｎθ，ｃｏｓθ的泰勒展开式进行的，因而计算精度高，并经过上机验证．

This paper presents a generation algorithm of ellipses with sectrin increments. By utilizing a few expressions

the calculation amount is reduced. Afterpreprocess

a couple of graphic points are only calculated by 9 times subtraction.The provided expression is based on Taylor expansion of sing and cosθ

so the calculation is very prevue. Algorithms are tested on computer

and the results arevery well.
