读取包含顶点和面的ASCII STL文件，并将其构造为矩阵“顶点”、“颜色”和“面”。之后，使用各小模块在Matlab上建立模型。
Read ASCII STL file which contains vertexes and faces and structure it to matrixes "vertexes", "colors" and "faces". after that I use patch to build model on matlab.
本代码使用C++ mex函数读取STL文件，使它运行得比Matlab函数的读取速度快得多。
I used C++ mex function to read STL file so it can run much faster than read on matlab function.
本代码的运行环境为MacOS version 10.14.5，Matlab 2018a。
It was built on MacOS version 10.14.5
Matlab 2018a
