应用八叉树编码法划分点云邻域空间为多个指定边长的子立方体，保留每个子立方体中距中心点最近的点，实现从空间整体角度对点云的精简。对三维模型数据进行了精简测试，证明了该算法的有效性和实用性。 -Octree encoding application point cloud into space for the neighborhood more than the specified sub-cube side, keep away from each sub-cube in the center o

用OpenTK做的点云浏览程序，使用八叉树管理点云数据，采用视景体切割和显示列表加速，打开常用的LAS格式点云(Using OpenTK to do point cloud browsing program, using octree management point cloud data, using visual cutting and display list acceleration, open the commonly used LAS format point cloud)
