OpenGL实用开源代码列表

有了网络的最大好处就是可以资源共享。网络是最大的知识库，也是最好的老师，正所谓“没有你想不到的，只有你找不到的”。以下是我收集的以游戏编程，OpenGL 3D编程相关的免费扩展库资料。不断更新中，如果你有好的建义，也请把函数库名及大概功能写上，本人负责收集整理。免费共享

SDL

在3D的世界里，SDL可真所胃是大名顶顶，正所谓“为人不知陈近南，自称英雄也枉然”，因此呢，如果你是做OpenGL开发的，一定要认识一下SDL。我们都知道，在windows系统中，有一个DirectX是游戏开发商的首选的开发包，其背后只支持的Direct3D作为三维图形接口。而SDL就被认为是非window系统中的DirectX，而且是开源的。SDL所使用的3D图形接口是OpenGL。但除了图形之外，它还支持对声音、键盘、鼠标、操纵杆、2D图像等等的底层处理。现在已有不少游戏使用这个开发包进行开发。

SDL是跨平台的，目前支持的系统有：Linux, Windows, Windows CE, BeOS, MacOS, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX

SDL 是用C语言写的，但是能很好地兼容C++语言。并且能被其它语言绑定使用，如： Ada, C#, Eiffel, Erlang, Euphoria, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP, Pike, Pliant, Python, Ruby, and Smalltalk.

SDL发布支持GNU LGPL v2.0 许可协议。也就是说SDL可以免费用于商业应用。

glew(OpenGL Extension Wrangler Library )

GLEW是一个跨平台的C++扩展库，基于OpenGL图形接口。使用OpenGL的朋友都知道，window目前只支持OpenGL1.1的涵数，但OpenGL现在都发展到2.0以上了，要使用这些OpenGL的高级特性，就必须下载最新的扩展，另外，不同的显卡公司，也会发布一些只有自家显卡才支持的扩展函数，你要想用这数涵数，不得不去寻找最新的glext.h,有了GLEW扩展库，你就再也不用为找不到函数的接口而烦恼，因为GLEW能自动识别你的平台所支持的全部OpenGL高级扩展涵数。也就是说，只要包含一个glew.h头文件，你就能使用gl,glu,glext,wgl,glx的全部函数。GLEW支持目前流行的各种操作系统（including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris）。

NVSG

The NVIDIA Scene Graph Software Development Kit (NVSGSDK) is an object-oriented programming library for creating scenegraph-based applications. The NVSGSDK provides a comprehensive set of classes that developers can easily combine and extend to create fast and reliable graphics applications.

CG_GL

CG_GL is OpenGL API-based open source engine for creating 3D effects. The new release adds depth-of-field with lens blur, and motion blur using shaders. Older version of the engine work on GeForce4 and support full screen blur, transparent object distortion, and glow. Engine is available here: http://tweety3d.no-ip.org. There are also other 3D related programs.

OpenSteer for AI. [MIT license]
Fluid Studios provides a memory manager, matrix class, font generator, radiosity processor, and various other things.
Panda3D (Game/graphics lib, released by Disney after being used for Toontown Online)
math3d++ provides the normal matrix, vector and quaternion classes, and their associated operations.
BMF_Font bitmap font library (and font texture generator)
OpenSceneGraph - 3D engine.
Demeter Terrain Engine [LGPL]

OGLWFW （OpenGL Window Framework） and basically does what it says on the tin, acts as a framework to create OpenGL windows. here

ARToolKit An augmented reality toolkit, works really nice and very fun to play with. Documentation is still in the works though so you will have to do with the examples.
MXRToolKit I haven't used this one but it appears to offer about the same as ARToolKit except it comes with documentation.
MathGL++ MathGL++ is a class library for fast C++ maths for use in OpenGL C++ projects. Easy to use and similar to the OpenGL API. Matricies, Vectors, Quaternions, Linear polynomials with eigen systems are all going to be included.

ManagedGL - The cross-platform .NET game library. Development ManagedGL 1 is stalled in faviour of ManagedGL 2. Currently mostly 2D graphics.

LibUFO GUI library (for OpenGL) [LGPL] 一个基于OpenGL的界面库
Crazy Eddie's GUI (another GUI lib)另一个比较有名气的游戏界面库，被OGRE游戏引擎收录使用。

HGE is a greate library for creating hardware accelerated 2D games for windows that is free for freeware games.

Novodex under physics libraries, free for non-commercial use.一个物理引擎，现在被收购了，改名为：PhysX

Pixel Toaster
http://www.pixeltoaster.com/
Open source c++ library for realtime software rendering.
It gives you a truecolor or floating point framebuffer at your choice, then converts the pixels to the display on the fly. Keyboard and mouse input, and a high resolution timer are also provided.
Currently supports only Windows (DirectX9), but ports to MacOS X and Unix (XWindows etc) are underway.

PTK . PTK is a great Mac/Windows 2d library running on top of OpenGL (so it's fast). It's free for freeware but it does have a PTK Watermark in the corner

MMXRand Almost twice as fast as the original Wagner's C++ code using Pentium MMX instruction by Matthew Bellew:
Tao Framework - .Net libraries for Cg, DevIL, FreeGLUT, ODE, OpenAL, OpenGL, and SDL.

OPAL - Open Physics Abstraction Layer, currently wraps just ODE I think but could be adapted to use other libraries. Choice of BSD or LGPL license.

Blitz++ (math library for C++)

PortAudio does cross-platform audio output and input using callbacks.

GLFTFont - zlib license
Not exactly a library, but a simple class that bridges freetype and OpenGL allowing drawing of truetype fonts in OpenGL. It's functionality is requested often enough I figured I'd release it

Object-Oriented Input System (OIS)
OIS is a library for cross-platform input management. It is under the zlib/libpng license. The library supports keyboard, mouse, and joystick/gamepad input. Action mapping is included in one of the demos, and force feedback is planned for the 0.4.0 release (currently in development).

libMikMod is a audio module player and library supporting many formats, including mod, s3m, it, and xm. Originally a player for MS-DOS, MikMod has been ported to other platforms, such as Unix, Macintosh, BeOS, and Java. libMikMod falls under the LGPL agreement.

GLM - a Math Library for OpenGL

http://members.tripod.com/markus_ilmola

This library contains useful math functions that are needed when

programming with OpenGL. Mostly vector and matrix math.

GIMPACT : Collision detection library.
