用于点云切片功能的实现，非常好用，可以计算密度、厚度、等内容(For point cloud slicing feature to achieve very easy to use, you can calculate the density, thickness, etc.)

Matlab-瑞利波模拟程序，用于面波入射模拟(Matlab-Rayleigh wave simulation program for surface wave incident simulation)

glTools oh god what i must wrote here?

DEM的读取与显示 实现大规模地形显示(DEM read and display of large-scale Terrain)

用于时延的三维定位，可用，麦克风阵列最好是立体面，这样不会出现奇异值(Three dimensional positioning for time delay is available, and microphone arrays are preferably stereo surfaces, so that no singular values appear)

迭代最邻近点算法进行3D点云的匹配，四元数方法求旋转(ICP algorithm for point clouds)

说明：  可以参考视频进行三维建模，使用三维建模软件catia(You can refer to the video for 3D modeling, and use the 3D modeling software CATIA.)

采用C++语言，Direct3D下用shader实现简单粒子的源码，初学者可借鉴(Using C++ language, achieved under Direct3D shader source code using simple particles, beginners can learn)

这是一个简单的3D光束图像的显示，用于描绘其射线传播过程(This is a simple 3D beam image used to describe the ray propagation)

三维均匀介质的高阶交错网格弹性波方程数值模拟（未加PML吸收边界条件），模拟结果以切边形式显示(Numerical simulation of three-dimensional homogeneous medium of high-order staggered elastic wave equation (not PML absorbing boundary conditions), the simulation results are displayed in the form of trimming)
