voidline(intx0,inty0,intx1,inty1,TGAImage ,TGAColorcolor){boolsteep=false;//判断斜率高的那一个if(std::abs(x0-x1)<std::abs(y0-y1)){std::swap(x0,y0);std::swap(x1,y1);steep=true;}//判断左右if(x0>x1){std::swap(x0,x1);std::swap(y0,y1);}intdx=x1-x0;intdy=y1-y0;fl...

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...
The present paper focuses on effective approach to minimize the error in the existing Bresenham's Line Drawing Algorithm (BLDA) in computer graphics. In this method, we consider three different values of h, i.e., 1, 0.5 and 0.1. For h=1, all the results of BLDA have been verified and...
A simple implementation of Bresenham's line drawing algorithm. See the Wikipedia entry for details on what that is. Note that this is a simple implementation. It is written in Pure Python (without e.g. numpy), so it is relatively slow. I found some beauty in combining the classic algorith...
