摘要
本文提出了四条圆弧近似代替椭圆,利用画圆弧算法中其主循环中无乘、除、开方等运算的优点,使画椭圆的计算量大大减少。本文同时对该近似算法所产生的误差进行了分析。
This paper puts forward an algorithm that draws an ellipse with four circle-arcs. In the algorithm of drawing an arc,no any arithmetics such as multiplication, division and extraction are fully used, so it diminishes the calculating magnitude in large quantities. We also analyse the error produced by this approximate algorithm.
