我是新手
不太懂啊

哪位高手给我注释以下啊
----------------解决方案--------------------------------------------------------
既然可以写出来
怎么会看不懂呢???
奇怪ing~~~~~~~~

----------------解决方案--------------------------------------------------------
不是我写的啊

我想学学

能注释一下吗???谢谢啊
----------------解决方案--------------------------------------------------------
我也不会````LZ``可以问问这个程序的作者``

首先``我问你``单独看每条语句``你懂不``

不懂``你就要看了``

我还想知道怎么写WINDOWS呢``
----------------解决方案--------------------------------------------------------
看了这才发现我的图形学算是白学习了，
----------------解决方案--------------------------------------------------------
OpenGL才是图形学的王道，何必叹息
----------------解决方案--------------------------------------------------------
不错的东东.
