Drawing the Curve of Implicit Function ard Calculation using Positive-Negative Algorithm;
利用正负法绘制隐函数曲线及运算
By analysing the algorithms of Bresenham drawcircle,right-and-lose drawcircle and midpoint drawcircle,comparing their proceduze,run speeds and the small circle radiuses they display,the virtues and defects of the three algorithms are analysed synthetically.
通过对B resenham画圆法、正负画圆法、中点画圆法的算法分析,以及实现算法的程序运行速度和程序存储空间分析的比较,对此3种算法进行综合的优劣分析。
