Draw line--Bresenham Algorithm Basic1、Bresenham算法绘制三角形边框使用Bresenham算法绘制三角形边框,我们先获得取值范围在-1.0f~1.0f的三个点坐标,分别乘500。将三个点两两配对,通过Bresenham算法获得绘制直线的所有点的坐标,除以500再存在数组中,最后通过glDrawArrays(GL_POINTS, 0, length)绘制直线,三条直线组合成...
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...
