以VC++作为开发平台，利用C++标准IO库的ifstream类型定义对象并绑定STL文件，再用标准库string类型中的getline逐行读取绑定的STL文件，最后，应用OPenGL绘制三角面片编程技术实现对STL文件格式的直观显示-Ifstream type definition object using the C++ standard IO library with VC++ as a development platform, and bind the STL file, getline read line by line and then the standard library string type in the binding of the STL file, and finally, the application of OpenGL drawing triangular patches programmingtechnology to achieve a visual display of the STL file format
