射包(Convex Hull)是计算几何中的一个重要概念,指的是给定点集的最小凸包。具体来说,射包是包含点集PPP 的最小凸多边形(或凸多面体)。从几何上看,射包可以被认为是用橡皮筋包裹点集后形成的形状。 1. 射包的定义 给定一个点集P={p1,p2,…,pn}射包(Convex Hull)是满足以下条件的集合: 包含P...
大数据算法课程笔记2:2D Convex Hull 技术标签:大数据算法 1. 题目简介 Input: n points in the plane p1,p2,⋯,pn, where pi=(xi,yi) Output: 包含所有点的最小凸多边形的所有边 2. 基本思想 :Divide and Conquer 先把点集一分为二,分别求取相应凸多边形,然后对两个凸多边形合并。 3. 具体算法 sort...
Convex Hull using Divide and Conquer Algorithm in C - In this tutorial, we will be discussing a program to find the convex hull of a given set of points.Convex hull is the smallest polygon convex figure containing all the given points either on the boun
