3D Without Boundaries
VirtualGL redirects 3D commands from a Unix/Linux OpenGL application onto a server-side GPU and converts the rendered 3D images into a video stream with which remote clients can interact to view and control the 3D application in real time.
Open Source Solid Modeling CAD
BRL-CAD is a powerful cross-platform constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing for rendering & geometric analyses, network distributed framebuffer support, image & signal-processing tools.
3D game engine (more powerful redesign of the Cube engine) and FPS game
for the latest release see either - https://github.com/OGRECave/ogre - https://bitbucket.org/sinbad/ogre/ An efficient, object-oriented hardware accelerated 3D engine. It abstracts the differences between APIs and platforms and allows scene-oriented coding through an easy to use object model. Adaptable to multiple scene types (indoor, outdoor, whatever)
QuteScoop is a platform-independent status indicator for VATSIM. It's available for Windows, Mac and Linux.
Maxwell Render for Blender
B-Maxwell add-on offers seamless integration with Maxwell Render and Blender
Equalizer is the standard middleware to create parallel OpenGL-based applications. Please visit https://github.com/Eyescale for current development information.
A techonogically advanced engine using C++ and ASM as languages.
A techonogically advanced engine using C++ and ASM as languages, with improved performance and a almost virtually infinite triangle count support, even on slower and older machines. It haves a full shader system, physics system (DOE Based), 100% physically correct lightning and colour grading, and supports various popular formats in 3D modelling and gaming scene. It was previously under a heavy eula policy, but now is under GPL because of internal problems.
Horde3D is a small 3D rendering and animation engine. It is written in an effort to create a graphics engine that offers the visual effects expected in next-generation games while at the same time being as lightweight and conceptually clean as possible. Further development has moved to https://github.com/horde3d/Horde3D where you're also able to download new releases.
Parallel GLUT is a parallel implementation of the OpenGL utility toolkit (GLUT) library. It adds a minimal set of constraints and extensions to the GLUT API, allowing the usage of multiple GPU's for multiple display devices and/or increased performance.
Pear3DEngine is a modern and modular 3D development framework
Pear3DEngine is a modern and modular 3D development framework that lets you create professional games, simulations and more. You are free to develop your program in C + +, XML or LUA and publish it as open source software or selling it as a commercial program. The rendering engine uses internally OpenGL or DirectX optionally. The planned editor supports software development on Linux, Windows and maybe MacOS X. DirectX 9 and therefore Windows XP are currently not supported and support is not planned in the future. One goal of the Pear3DEngine Framework is to use the latest and most promising algorithms and techniques from the 3D and IT scene.
3D tool for visualizing and developing shaders
Shadow Grounds is a shader development environment focused on providing a dynamic 3D environment for quick and comprehensive testing /visualization of shaders. At present, the project uses the OpenSceneGraph rendering API, and is thus limited to GLSL shaders. Support for other rendering API's (and other shader languages) is planned. Interface is console-driven with eventual plans for a GUI.
The Zenipex Library is a game development framework, created with the goal of allowing someone with some knowledge of C++ to create 3D games for platforms including Windows, MacOS X, and Linux. OpenGL and Direct3D 9 are both supported.
