对于一个类似于其他程序结构制备的opengl程序…

代码说明：

OpenGL编写的程序结构类似于用其他语言编写的程序。实际上，OpenGL是一个丰富 的三维图形函数库，编写OpenGL程序并非难事，只需在基本C语言中调用这些函数，用法同-OpenGL procedures for the preparation of a structure similar to other procedural languages. In fact, OpenGL is a rich three-dimensional graphics library, OpenGL procedure is not difficult to prepare, just in the basic C language calls to these functions, use the same
