OpenGL實用開源代碼列表

有了網絡的最大好處就是可以資源共享。網絡是最大的知識庫，也是最好的老師，正所謂“沒有你想不到的，只有你找不到的”。以下是我收集的以遊戲編程，OpenGL 3D編程相關的免費擴展庫資料。不斷更新中，如果你有好的建義，也請把函數庫名及大概功能寫上，本人負責收集整理。免費共享

SDL

在3D的世界裏，SDL可真所胃是大名頂頂，正所謂“爲人不知陳近南，自稱英雄也枉然”，因此呢，如果你是做OpenGL開發的，一定要認識一下SDL。我們都知道，在windows系統中，有一個DirectX是遊戲開發商的首選的開發包，其背後只支持的Direct3D作爲三維圖形接口。而SDL就被認爲是非window系統中的DirectX，而且是開源的。SDL所使用的3D圖形接口是OpenGL。但除了圖形之外，它還支持對聲音、鍵盤、鼠標、操縱桿、2D圖像等等的底層處理。現在已有不少遊戲使用這個開發包進行開發。

SDL是跨平臺的，目前支持的系統有：Linux, Windows, Windows CE, BeOS, MacOS, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX

SDL 是用C語言寫的，但是能很好地兼容C++語言。並且能被其它語言綁定使用，如： Ada, C#, Eiffel, Erlang, Euphoria, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP, Pike, Pliant, Python, Ruby, and Smalltalk.

SDL發佈支持GNU LGPL v2.0 許可協議。也就是說SDL可以免費用於商業應用。

glew(OpenGL Extension Wrangler Library )

GLEW是一個跨平臺的C++擴展庫，基於OpenGL圖形接口。使用OpenGL的朋友都知道，window目前只支持OpenGL1.1的涵數，但OpenGL現在都發展到2.0以上了，要使用這些OpenGL的高級特性，就必須下載最新的擴展，另外，不同的顯卡公司，也會發布一些只有自家顯卡才支持的擴展函數，你要想用這數涵數，不得不去尋找最新的glext.h,有了GLEW擴展庫，你就再也不用爲找不到函數的接口而煩惱，因爲GLEW能自動識別你的平臺所支持的全部OpenGL高級擴展涵數。也就是說，只要包含一個glew.h頭文件，你就能使用gl,glu,glext,wgl,glx的全部函數。GLEW支持目前流行的各種操作系統（including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris）。

ShaderGen 提供簡單的UI接口讓你可以產生固定管線(Fixed Pipeline)的Shader.如果你對Shader不熟悉的話,這是一個不錯的入門工具.詳細網址如下:

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] 一個基於OpenGL的界面庫
Crazy Eddie's GUI (another GUI lib)另一個比較有名氣的遊戲界面庫，被OGRE遊戲引擎收錄使用。

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.一個物理引擎，現在被收購了，改名爲：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.
