open source about openGL

Crystal Space is our main project. It is a free cross-platform software development kit for realtime 3D graphics, with particular focus on games.

 

GLFW is a free, Open Source, multi-platform library for creating OpenGL contexts and managing input, including keyboard, mouse, joystick and time. It is intended to be simple to integrate into existing applications and does not lay claim to the main loop.

 

AntTweakBar is a small and easy-to-use C/C++ library that allows programmers to quickly add a light and intuitive graphical user interface into graphic applications based on OpenGL, DirectX 9 or DirectX 10 to interactively tweak their parameters on-screen.

 

OpenSceneGraph is an OpenSource, cross platform graphics toolkit for the development of high performance graphics applications such as flight simulators, games, virtual reality and scientific visualization. Based around the concept of a SceneGraph, it provides an object oriented framework on top of OpenGL freeing the developer from implementing and optimizing low level graphics calls, and provides many additional utilities for rapid development of graphics applications.

 

Horde3D is a small open source 3D rendering engine. It is written in an effort to create a graphics engine that offers the stunning visual effects expected in next-generation games while at the same time being as lightweight and conceptually clean as possible. Horde3D has a simple and intuitive interface accessible from virtually any programming language and is particularly suitable for rendering large crowds of animated characters in next-generation quality.
