Vincent is an open source project for developing a compliant software implementation of the OpenGL ES API for mobile devices. The initial target platform are Pocket PCs and Smartphones operating under Windows Mobile 2003. A unique aspect of Vincent is a runtime compilation infrastructure that creates optimized rasterizer code for the current graphics context settings using a JIT compiler. This runtime compilation approach, which is otherwise only available in commercial products, distinguishes the current project significantly from other similar open source projects that aim for providing implementations of the OpenGL API. All code created by this project is released under a liberal BSD-style license, which allows for the creation of commercial derivatives and commercial distributions. The project is registered as an official adopter of the OpenGL ES API and has access to the conformance test suite. A beta version of this library is available for download.
GPUmesh offers developers a simple way to send geometry to the GPU. The user chooses which type of mesh storage is desired (display list, vertex buffer, indexed vertex buffer, ...) and GPUmesh automatically performs the required conversions. The same mesh specification mechanism is used for Direct3D and OpenGL, thus simplifying the task of writing mesh loaders. GPUmesh relies on a mechanism similar to the begin/end approach of standard OpenGL which has proven to be easy to use and very convenient. A complete vertex format specification mechanism is also provided to manage vertex attributes. GPUmesh is free. Full source code and examples are included in the package.
The v1.2 of the Gizmo3D scene graph adds full support for hierarhical OpenGL Shading Language shaders with fallback to ARB vp/fp or fixed function pipeline, physics integration with Meqon physics library, improved window integration with Mac OS X, QT, X11, Win32, wxWindows, and real time distributed network graphic objects. The Gizmo3D is now part of a larger framework called GizmoSDK wich is free for non commercial applications.
zeGraph is an object rendering system designed for scientific data visualization and yet can be used to create 3D arts in a broad scope. It is small, fast, and easy to use. The OpenGL API is used as the rendering engine. This distribution is a binding of zeGraph to Lua, a platform independent, light weighted, simple, and powerful script language.
breve is an OpenGL-based simulation environment which allows users to define the behaviors and interactions of different types of agents in a simulated 3D world and observe the emergent behaviors. This new v1.9 features MPEG movie and PNG image export on all platforms; a fullscreen mode for Linux and Windows; improvements to shadows and reflections; and general improvements and optimizations in the OpenGL-based rendering engine.
SGL is a mature and robust cross-platform OpenGL-based 3D Scene Graph API, written in C++. SGL supports a number of 3D file formats (obj, 3ds, TXP, OpenFlight 15.7, VRML 2.0, MD3), and a variety of image file formats. SGL provides build environments for Linux, Solaris, IRIX, Windows (VC++ and cygwin), VxWorks, and MAC OSX. The latest v0.7.0 release adds support for OpenGL Shading Language, Image Caching, Qt improvements, Nvidia’s Cg, Shadow Mapping, multisampling, various ARB extensions, new build platforms, and bug fixes and improvements. (check the downloads link for this new build).
SuperSpriteSurface v1.0 2D OpenGL-Accelerated Game Engine for REALbasic
SuperSpriteSurface is a middleware solution for REALbasic developers that allows REALbasic developers to create Macintosh games that utilize the OpenGL API, advanced collision detection and time-based animation.

VRizer takes conventional OpenGL-based games or software for virtual reality and creates a library that, when preloaded, intercepts the proper OpenGL/SDL calls to create 2 stereoscopic views out of 1 single frame stream. The original software is not altered in any way but the output is stereoscopic.
This paper and OpenGL API demo with source shows how to to real-time atmospheric scattering. It is based on the SIGGRAPH93 publication: “Display of The Earth Taking into Account Atmospheric Scattering”, which is a mathematically-heavy non-realtime algorithm. The demo focuses on optimizations that allow the algorithm to run in real-time without creating large lookup buffers, which allows almost all of the scattering coefficients to be changed quickly at run-time.
Crystal Space is an Open Source 3D engine that runs on Linux, Windows, and MacOS/X. The new in-development renders supports OpenGL 1.5 features like shaders (CG, vertex and fragment shaders), stencil shadows, etc. The renderer design is working and most important things are done. However, there are still a lot of missing features and there is a lot of testing, performance tweaking, and bug hunting that needs to be done.
GUN-TACTYX is a more advanced version of a programming game called CROBOTS. Players must program the AI algorithms of their own team of bots and follow the fights against other warriors in a 3D arena. The engine (source code available) is based on the OpenGL APIand renders QUAKE3-style graphics to improve the realism of the battle field and involve more the players. This release extends the simulator with support of Soccer-like matches and adds grenades to the usual Fight mode. It also includes support for ARB extensions texture_env_combine, texture_cube_map, vertex_buffer_object and vertex_program. The extensions are used for simple pex-pixel lighting and for models animation. However the game does not require any extension to work properly, but the use of the latest OpenGL 1.5 drivers and a GeForce1 or Radeon graphics card class are recommended.
Bloxter is an OpenGL-based arcade/puzzle game with 3D graphics, falling blocks, bonus lamps, alien monsters and more. For Win and Mac OS X.
The new RADEON X800 graphics technology features an HD pixel shader engine with up to 16 parallel pixel pipelines. it support the OpenGL Shading Language and is ready to suppport the next generation of the OpenGL API.
The new release of the Sylphis 3D game engine adds support for OpenGL 1.5 and the newer video cards with fragment programs support. The engine already supports stencil shadows and realistic physics.
