摘要
利用椭圆的参数方程,给出了以等分角度为增量的绘椭圆的一种算法,并分析了算法的误差.采用正弦和余弦的泰勒展开式构造的迭代公式,计算一个绘图点只需9次加法.
This paper makes use of the elliptical parameter equation, present a generation algorithm of ellipse with division angle increments,and makes error analysis. Adopt the iterative formula that forms Taylor's expansion of sine and cosine,and compute a graphic points are only calculated by 9 times addition.
