访问最底层LOD模型路径，打开后获取顶点数据和PirmitiveSet，重绘模型的三角面片(Visit the bottom LOD model path, open it, get vertex Array and PirmitiveSet, and redraw the triangle of the model.)

用于求取三维点云数据的法向量，我的人脸建模就是用的这个，效果很好，但必须保证点云没有重叠的，否则会出现严重错误。(Strike a 3D point cloud data for normal vectors, and my face is to use this model, the effect is very good, but must ensure that there is no overlap of the point cloud, there would be a serious mistake.)

实现如何使用顶点vertex来创造一个正方体(Implement a cube by using vertex)

说明：  3d 地形渲染DEMO lod 采用lod技术　多层渲染(3d terrain rendering using DEMO lod multi-lod rendering technology)

基于LOD技术的3D海底地形仿真系统。主要讲述海底地形的绘制及仿真系统的组成。(Based on the LOD 3D seafloor topography simulation system. Focuses on the composition of the seabed topography mapping and simulation system.)

简单的三维高斯束正演程序啊，可以实现简单的高斯束正演(3d gaussian beam forward)

说明：  一个初学D3D的Demo,有望高手给点意见(D3D a beginner)

在P4P问题中,当空间4个点共面时,不仅摄像机坐标系与物体坐标系之间 的旋转矩阵R和平移向量t可以线性求解,而且可以同时确定摄像机的有效焦距f和像素比例，该程序设计模拟已知相机矩阵M情况下由已知三维空间点和图像坐标情况求解相机外参数矩阵(When space four points coplanar P4P problem, not only between the camera coordinate system and the object coordinate system rotation matrix R and translation vector t Can be solved linearly, and can determine the camera s effective focal length f and pixel ratio, the program is designed to simulate a known camera matrix M Camera outside the parameters matrix case solved by the known three-dimensional space points and image coordinates)

基于PCL的点云滤波中的体素栅格滤波算法，将点云数量过于庞杂的点云文件进行简化但保留其特征，减少后续处理的计算量(PCL VoxelGrid filter)
