中文说明：利用MATLAB直接读取数据文件（.obj），计算离散化高斯曲率，高斯曲率矩不变量。文件按函数分散，便于组合和修改，很方便。
English Description：
Using MATLAB to read data files directly (.Obj), to calculate the discrete Gauss curvature, Gauss curvature moment invariants. The file is dispersed by function, which is convenient for combination and modification.
