【CImg】三角形绘制算法实现
这周的CV基础练习是简单的图形绘制:比如说矩形、三角形和圆心什么的。会发现其实矩形和圆形的实现思路都很直白,矩形只需要确认两个对角坐标就可以了,圆心只需要确认圆心和半径,接着就是简单的遍历各个像素点判断。但是,三角形的绘制把数学渣的我难住了,然后去查了一下资料,受到了知乎某位大神的启发:如下截图:于...

[BJWC2011]最小三角形(分治+最近点对)
题面:BJWC2011 最小三角形$ solution: $昨天才学完平面最近点对,今天就要求平面最近的三个点,显然不是巧合。仔细一思考,我们用来求平面最近点对的方法不就可以用到三个点上吗?就是按x轴排序,然后不断二分,在向上回溯的同时更新我们的ans,比如当前这个区间,距离中点水平距离超过ans/...
