接下来讲卷包裹算法: 我们先找到一个在凸包上的点,然后卷过去 伪代码如下: 初始化st[]=0,j=0,endpoint=P0 do { 将endpoint加入队列st. 找到任意从P0点出发,转向最右的点P endpoint=P }until endpoint=P0 1. 2. #include<cstdio> #include<iostream> #include<cstdlib> #include<cstring> #include<algor...
一组平面上的点,求一个包含所有点的最小的凸多边形,这就是凸包问题了,这可以形象地想象成在地上放置一些不可移动的木桩,用一根绳子把他们尽量紧地圈起来,并且为凸边形,这就是凸包了。 二.GiftWrapping算法 又叫卷包裹算法,复杂度O(n*h),n表示共几个点,h表示极点个数。 理论准备 向量叉积:也被称为矢量...
1) gift-wrapping algorithm 卷包裹算法例句>> 2) Gift wrapping method 卷包裹法 1. Gift wrapping method and Graham method are traditional arithmethic of converx hull calculating,and arithmetic steps is very complex. 卷包裹法和格雷厄姆法是凸包求解的经典算法,但其算法步骤较为复杂。 2. Finally,...
The principle of the algorithm is based on duality and especially on the fact that the vertices of the preimage correspond to faces of the input set S or of its chords set S S ∪ { ( 0 , 0 , 1 ) }. It allows to go from one vertex to another by gift-wrapping until the whole ...

A conventional gift-wrapping algorithm for constructing the three-dimensional convex hull is revised into a numerically robust one. The proposed algorithm places the highest priority on the topological condition that the boundary of the ... K Sugihara - 《J.comput.syst.sci》 被引量: 68发表: 199...
