首先加入两个点 A 和 B。 然后插入第三个点 C,并计算AB→×BC→的向量积,却发现向量积系数小于(等于)0,也就是说BC→ 在AB→的顺时针方向上。 于是删去 B 点。 按照这样的方法依次扫描,找完 "下壳" 后,再找 "上壳"。 cpp #include<algorithm>structPoint{doublex, y;// 重载减法运算符,用于计算向...
Convex hull: the smallest polygon that covers all the points in the given set. Application: Farthest pair problem, shortest Path across the boundary. Algorithm: Find the point with the lowest y-coordinates p, then iterate through all the points in the order of polar-angle relative to the p....

凸包计算通常使用Convex Hull Algorithm,这是一种考虑所有点的有效计算凸包的算法。它首先考虑所有点的范围,然后从该框架中求出最大边缘。它有效地建立了点的位置,以确定一组点的几何结构,并建立最外层边缘的凸多边形。 凸包也可以用于几何图形模型,用于形成所有离散点的关联。它涵盖了一组离散点,为多边形提供多边形形...
Better algorithm: However, we should see that sometimes that there are lines we don’t need. For example, a line that can’t produce the minimum value among all the lines in the set for allxvalue. “Bshould be ignored since eitherAorChas a loweryvalue thanBfor allx.” ...

I used the following algorithm to draw the Convex hull. First of all, I found the point p1 with the smallest x coordinate. Then, I chose a vector v1 pointing up the y axis. Then I found the point p2 for which the line p1p2 made the smallest angle with v1, and let v2 be a ve...
