Our goal is to create a community-led, cross-platform, open source Software Development Kit that would contain up-to-date documentation, sample code, tutorials and utility libraries for OpenGL 3.0 and beyond. We want to make it easier and simpler to introduce newbie programmers to the world of OpenGL while giving also a centralized location of reference materials for other developers.

Meta, is a WebKit port suited to embedding in OpenGL and 3D applications

CGLX (Cross-Platform Cluster Graphic Library ) is a flexible transparent OpenGL-based graphics framework for distributed high performance visualization systems in a master-slave setup. The framework was developed to enable OpenGL programs to be executed on visualization clusters such as a high resolution tiled display system and to maximize the achievable performance and resolution for OpenGL based applications on such systems.

LÖVE is an open-source 2D game engine which uses the versatile Lua scripting language to create dynamic gaming experiences. It relies on OpenGL graphics and the SDL interface library to allow for cross-platform implementation and is an all-encompassing gaming environment for the development and enjoyment of 2D games.

Agar is a toolkit for graphical applications. Agar is integration-friendly, extensible, highly portable, and can use different graphics APIs such as SDL and OpenGL. Agar consists of two libraries: Agar-Core provides generic object functions and portability interfaces. Agar-GUI includes the base GUI system and a comprehensive set of standard widgets. Both are implemented in C, but are usable from other languages. When compiled with threads support, both libraries are efficiently thread-safe. The distribution also includes some more specialized libraries aimed at specific applications. Agar is free software. Its source code is freely usable and re-usable by everyone under a BSD license, which allows use in commercial applications free of charge. Agar is stable, well-maintained and has been growing organically since early 2002.

Visualization Library is an open source C++ middleware for 2D/3D graphics applications based on the industry standard OpenGL, designed to develop portable applications for the Windows XP, Windows Vista and Linux/X11 operating systems.

GLV (Graphics Library of Views) is a GUI building toolkit written in C++ for Linux, OSX, and Win32. GLV is specially designed for creating interfaces to real-time, multimedia applications using hardware accelerated graphics. GLV has no dependencies on other libraries other than OpenGL which is provided by all modern operating systems. Although windowing is technically not a part of GLV, it does provide an abstraction layer for creating bindings to a particular windowing system for creating an OpenGL context and getting mouse and keyboard input

Lumina is a free crossplatform development environment for GLSL shaders. An ECMA script based language is used for tools and rendering control. Lumina provides maximum flexibility that allows the user to build renderer prototypes for deferred shading, depth peeling or HDR rendering, as well as vertex shader and instancing accelerated bezier objects, skinng or GPU based particle systems.
