KD Tree KNN This source code implement KD Tree in C# This is for my research Performance very good Using Parralel proceessing

实现构建k-d树并且实现k-d树上的最邻近查找算法-Build a kd-tree and kd tree nearest neighbor search algorithm

kd树，分割k维数据空间的数据结构。主要应用于多维空间关键数据的搜索（如：范围搜索和最近邻搜索）。K-D树是二进制空间分割树的特殊的情况。-KD tree, the data structure of K dimensional data space. It is mainly used in the search of key data in multidimensional space (such as range search and nearest neighbor search). K
