直接运行TestMyCrust.m, 读取点云txt,或者直接加载mat文件 运行需要几分钟，耐心等待 完成后运行trianglenormal.m, 生成三角面片的法向量 运行完成得到tri.txt（组成三角面片的点的编号信息）,trinormal.txt(每个三角面片法向量数值)，diandian.txt(每个点云信息) 然后将三个数据当做stl_gen.exe的输入文件，得到trisuface.stl文件(run TestMyCrust.m, read point cloud file txt, or load mat file)

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)

用matlab编写的Delaunay三角化的程序，在points里面修改自己的初始点。(Delaunay triangulation using matlab program to modify the initial point, the points inside.)

一个简单的三3D环境漫游系统,终于可以实现三维环境渲染了(a simple three roaming 3D environment, can finally achieve a 3D environment exaggerated)

利用连续两张图片中莫尔条纹实现位移测量，对条纹区域像素灰度值采用正弦函数拟合(Moire fringe displacement measurement in two consecutive pictures, fitting the gray value of pixels in fringe region with sinusoidal function.)

土木工程-边坡工程-离散元3dec软件-边坡的建模和安全系数求解的命令流(Civil Engineering- Slope- Discrete Element 3dec software- modeling and solving safety factor of order flow)

说明：  重叠文字避让程序及lisp源代码,地形图里重叠文字一次性解决问题。(Procedures and avoid overlapping text lisp source code, topographic maps in overlapping text disposable solve the problem.)

用vrmlscript制作的三维场景绿化植树功能源代码及图片，用BS浏览器可查看，在控制台可以直接打印出生成的源代码，生成源代码可直接复制到场景中永久保存，相当于一个可视化的vrml绿化编辑器。(Produced by using three-dimensional scenes vrmlscript greening and tree planting function source code and pictures, with BS browser can view in the console can directly print out the generated source code to generate the source code can be directly copied to the permanent preservation of the scene, which is equivalent to a Visualization of VRML Green editor.)
