Gift-wrapping算法
WebNov 19, 2014 · 其实这种说法，和GiftWrapping算法的实现也有点异曲同工的感觉。 也就是先确定一个最边缘的点A，然后逆时针顺序寻找下一个与A构成的向量在逆时针方向上旋转角度最小的点。如果寻找到下一个点B，则继续用B点做基础点，寻找下一个点。 Web目录Unity 算法 之 点集中计算绘制 凸包 的简单整理一、简单介绍二、Graham扫描法第一种说明：第二种说明：三、代码（第二种说明） 四、参考文献算法（Algorithm）是指解题方案的准确而完整的描述，是一系列解决问题的清晰指令，算法代表着用系统的方法描述解决问题 …

In the two-dimensional case the algorithm is also known as Jarvis march, after R. A. Jarvis, who published it in 1973; it has O(nh) time complexity, where n is the number of points and h is the number of points on the convex hull. Its real-life performance compared with other convex hull algorithms is favorable when n … See more In computational geometry, the gift wrapping algorithm is an algorithm for computing the convex hull of a given set of points. See more The inner loop checks every point in the set S, and the outer loop repeats for each point on the hull. Hence the total run time is $${\displaystyle O(nh)}$$. The run time depends on the size of the output, so Jarvis's march is an output-sensitive algorithm See more For the sake of simplicity, the description below assumes that the points are in general position, i.e., no three points are collinear. The algorithm may be easily modified to deal with collinearity, including the choice whether it should report only extreme points (vertices … See more • Convex hull algorithms See more Web回顾凸包构造算法：极点法、极边法和增量构造法，其复杂度分别为O(n^4^)、O(n^3^)和O(n^2^)，效率经过优化已经大大提高了。接下来引入一种新的算法——Jarvis March，其复杂度也是O(n^2^)，但是相较于增量构造在最好情况下效率是较高的。 ...
