Consider a line with negative slope between 0 and 1 (i.e., small negative slope. Given that a linedrawing algorithm has plotted a point at (x,y), its choice about where to plot the next point is between (x+1,y-1) and (x+1,y). As usual there will be an error, , associated...
This process consists of two stages: clipping and drawing. These two stages are separated in current graphical applications. In this paper a new approach to line generation is proposed, which unifies these stages. The proposed algorithm is based on Bresenham's line generation algorithm to include...

2.1.如果线段ax+by+c=0与x=x1+1的交点y坐标大于(y+*y+1)/2则选右上那个点2.2.否则选右下那个点。3.画点4.跳回第2步5.结束算法的具体过程是怎样的呢,其实就是在每次画点的时候选取与实现直线的交点y坐标的差最小的那个点,例如下图:关键是如何找最近的点,每次x都递增1,y则增1或者不增1,由上图...
