Marching Cubes算法是三维离散数据场中提取等值面的经典算法,其主要应用于医学领域的可视化场景,例如CT扫描和MRI扫描的3D重建等. 算法主要的思想是在三维离散数据场中通过线性插值来逼近等值面,具体如下:三维离散数据场中每个栅格单元作为一个体素,体素的每个顶点都存在对应的标量值.如果体素顶点上的值大于或等于等值面值,则定义该顶点位于等值面之外,标记为“0”:而如果体素顶点上的值小于等值面值,则定义该顶点位于等值面之内,标记为“1”.由于每个体素单元有8个顶点,那么共存在2^8 = 2…

这题是学主席树的时候就想写的,,, 但是当时没写(懒) 现在来填坑 = =日常调半天lca(考虑以后背板) 主席树还是蛮好写的,但是代码出现重复,不太好,导致调试的时候心里没底(虽然事实证明主席树部分没出问题) #include <cstdio> #include <algorithm> using namespace std; ]; ]; ,N=,lastans=; ],nex[],list[]; ],h[],fir[],root[],f[],pos[]; ],near[],rm…
在某些数据访问层框架中,会使用show full tables from test like 'demo',来检查数据库的状态.当数据库中表的数量较少时,并没有出现严重的问题.但是当数据库中的表数量多余千个时,且并发数较高时,通过show processlist就会发现show full tables语句绝大部分处于checking permissions状态 | 2 | test | 192.168.15.128:57656 | NULL | Query | 0 | checking perm…
