对比不难看出,当k\in\left( 1,\infty \right)时,直线沿y轴方向的变化会“快于”沿x轴的变化。因此每次循环就从x坐标的递增改为y坐标的递增。如果不能理解,不妨动手画一画。 至此,我们就解决了k\in\left( 0,\infty \right)时,直线的绘制,那么类似的我们也可以写出k\in\left( -\infty,0\right)时,直...

For nearly thirty years Bresenham's algorithm has been the standard which subsequent efforts inline drawing have sought to surpass. The basic "line drawing" algorithm used in computer graphics is Bresenham's Algorithm. This paper describes a hybrid method which uses structural properties of raster ...

Bresenham's Algorithm for drawing lines is an efficient line-drawing algorithm widely used in computer graphics and image processing. Developed by Jack E. Bresenham, this algorithm determines the points of an n-dimensionalgrid that should be plotted in order to form a straight line between two gi...
Bresenham直线算法 Bresenham直线算法是用来描绘由两点所决定的直线的算法，它会算出一条线段在 n 维光栅上最接近的点。这个算法只会用到较为快速的整数加法、减法和位元移位，常用于绘制电脑画面中的直线。是计算机图形学中最先发展出来的算法。经过少量的延伸之后，原本用来画直线的算法也可用来画圆。且同样可用较...
