OpenGL函数库相关的API有核心库(gl)、实用库(glu)、辅助库(aux)、实用工具库(glut)、窗口库(glx、agl、wgl)和扩展函数库等。从图可以看出,gl是核心,glu是对gl的部分封装。glx、agl、wgl 是针对不同窗口系统的函数。glut是为跨平台的OpenGL程序的工具包,比aux功能强大。扩展函数库是硬件厂商为实现硬件更新利用OpenGL的扩展机制开发的函数。  

目前OpenGL的函数主要包含在3个库中:GL 函数库、GLU 函数库、GLUT 函数库

 GLU 库函数

包含有43个函数,函数名的前缀为glu。OpenGL提供了强大的但是为数不多的绘图命令,所有较复杂的绘图都必须从点、线、面开始。Glu 为了减轻繁重的编程工作,封装了OpenGL函数,Glu函数通过调用核心库的函数,为开发者提供相对简单的用法,实现一些较为复杂的操作。此函数由glu.dll来负责解释执行。OpenGL中的核心库和实用库可以在所有的OpenGL平台上运行。

 GLUT 库函数

包含大约30多个函数,函数名前缀为glut。glut是不依赖于窗口平台的OpenGL工具包,由Mark KLilgrad在SGI编写(现在在Nvidia),目的是隐藏不同窗口平台API的复杂度。 函数以glut开头,它们作为aux库功能更强的替代品,提供更为复杂的绘制功能,此函数由glut.dll来负责解释执行。由于glut中的窗口管理函数是不依赖于运行环境的,因此OpenGL中的工具库可以在X-Window, Windows NT, OS/2等系统下运行,特别适合于开发不需要复杂界面的OpenGL示例程序。对于有经验的程序员来说,一般先用glut理顺3D图形代码,然后再集成为完整的应用程序。
