【for Beginners】怎样开始学习OpenGL

  怎样开始学习OpenGL

什么是OpenGL:
OpenGL（“Open Graphics Library”）是图形硬件的软件接口。OpenGL包括大约250个不同的函数，程序员可以使用这些函数设定要绘制的物体和操作，来制作交互的三维应用程序。

OpenGL是专业图形处理，科学计算等高端应用领域的标准图形库。它的主要竞争对手是微软的Direct3D。OpenGL曾长期处于技术上的领先地位,但近年来Direct3D也迎头赶上。目前这两种图形API在性能上可说是旗鼓相当。不过OpenGL支持众多的操作系统，而Direct3D只在Windows平台上可用。因此OpenGL仍然广受瞩目。

有哪些游戏采用了OpenGL渲染？
多了去了，魔兽3啊，cs啊，doom啊，quake啊，等等等等等等......

怎样开始学习OpenGL:
你可以在OpenGL的官方网站http://www.OpenGL.org的Documentation中下载到官方教程和例子程序：
The OpenGL Programming Guide,这就是著名的red book（“红皮书”）

如果你英语不好，那么推荐你阅读:
《OpenGL超级宝典》是一本相当不错的中文教程。可以在http://www.vrforum.cn/forumdisplay.php?fid=29找到它的例子代码
《OpenGL编程权威指南》他是red book的中文译本，它的例子也就是red book的例子。

*Nate Robin的例子对你理解OpenGL很有帮助。http://www.gamedev.net/reference/articles/article839.asp

*The OpenGL Reference Manual（blue book）并不是一本入门教材，而是一本函数参考手册，可以从http://www.OpenGL.org的Documentation中下载下来，在实际学习中查询用

*NeHe的例子也是大家所喜爱的初学者例子。http://nehe.gamedev.net，在http://www.chinagamedev.net还有一部分的中文译文

***nehe的简单窗口例子（第二课）几乎含盖世界上的所有语言，如果想用自己喜欢的独特语言，可以参考http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=02最下方的联接，并结合C++的例子学习（大多数教材都是基于C++的，不过幸好我们真正关注的是OpenGL本身）
***Nehe这一课关注于窗口的建立，并以下语言的移植版本，按字母排序（我就不删除这些厄余信息了，这实在太多了>_< !）
