In computer graphics, theDDA algorithmis the simplest algorithm among all other line generation algorithms. Here, theDDAis an abbreviation that stands for"Digital Differential Analyzer". It is an incremental method, i.e. it works by incrementing the source coordinate points according to the values...

https://github.com/xiaohuihuiold/computer_graphics/blob/master/line/dda.c 最后 DDA的计算方法比直接套用直线方程的效率要高得多。虽然从一个乘法一个加法缩减到了一个加法,但是在进行计算中的浮点运算和取整依旧比较耗时。后面会接触绘制直线的其它算法。

一、数字微分分析仪(digital differential analyzer, DDA)方法是一种线段扫描转换算法。在一个坐标轴上以单位间隔对线段取样,从而确定另一个坐标轴上最靠近线路径的对应整数值。主要是根据直线公式y = kx + b来推导出来的,其关键之处在于如何设定单位步进,即一个方向的步进为单位步进,另一个方向的步进必然是小于1...
