OpenGL加载STL类型文件，进行显示，简单的旋转平移交互等操作，代码比较粗糙。-OpenGL load STL file types, display, simple operations such as interactive rotation and translation, the code is relatively rough.

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 TestM
