The OpenGL Extension Wrangler Library is a simple tool that helps C/C++ developers initialize extensions and write portable applications. GLEW currently supports a variety of operating systems, including Windows, Linux, Darwin, Irix, and Solaris.
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.
PyOpenGL is the binding layer between Python and OpenGL.
UPDATE: Chromium is no longer updated or maintained. The project is frozen. Chromium is a flexible framework for scalable real-time rendering on clusters of workstations, derived from the Stanford WireGL project code base.
G3D is a commercial-grade C++ 3D engine. It is used in commercial games, research papers, military simulators, and university courses. G3D supports real-time rendering, off-line rendering like ray tracing, and general purpose computation on GPUs. As of January 16, 2018, SourceForge is again the home of the active repository for G3D.
Ayam is a free 3D modelling environment for the RenderMan interface.
Earth orbits and coverage display in 3D on your laptop.
SaVi - simulate Iridium, Globalstar, O3b, Sirius Radio, GPS, Galileo and other satellite constellations, modify them, or design your own. Uses Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.
3D rendering and scene graph library
High-level 3D graphics library. Supports retained and immediate mode rendering, an extensible file format, plug-in renderers, a wide range of high level geometries, hierarchical models, and a consistent and object-orientated API.
A graphics program which allows to model and render 3D objects and scenes.
PyOSG is a python wrapper for the OpenSceneGraph. Version number corresponds to the version of OpenSceneGraph that PyOSG should work with (e.g. PyOSG 2.8 should work with OpenSceneGraph 2.8.x). Still in early stages, so email mday299 if any problems!
lucille is a parallel global illumination renderer with RenderMan interface support
The Alhacen Ray Tracer is an open source real time ray tracer aimed at achieving competitive 3d graphics performance on everyday computers while allowing for dynamic reflections and global illumination. It is written in the C programming language.
The Baja Engine is an advanced, easy to use 3D game engine for Mac, Windows, and Linux. Baja provides world-class 3D, 2D, audio, shader, scripting, editing, special effect, animation, and networking capabilities.
Death3D is a lightweight 3D rendering engine.
A fork of Sauerbraten/Cube2 (sauerbraten.org) with several multiplayer modes, online map editing, dynamic mapmodel physics, enhanced particle effects, unique weapons and powerups, and more. This project is currently not under active development.
Ignproj is an open source program developed by four students from EPITA, an engineer school in France. This program is able to transform a 2 dimensional map into an 3 dimensional map.
A C++ wrapper and utility classes for the mental ray API.
MyWorld is an open virtual reality and game engine. It is written and usable in C/C++. It has own abstract layers for Graphics and Physics. Actually we use Irrlicht for 3D-Rendering and GUI, and ODE for Physics. It is smart, powerful and easy to extend.
A Free Distributed Photon Mapping. It´s developed for a University project. Use MPI for distributed processing and OpenMP for internal parralelism.
A powerful cross-platform and open-source 3-D rendering engine.
Panda3D is a powerful 3-D rendering engine for many Unix-based and Windows platforms. See the Panda3D home page at https://www.panda3d.org for more information and for forums and downloads. The source code is no longer hosted at SourceForge, but is now available from GitHub: https://github.com/panda3d/panda3d
A web like collection of panels, browsable through a flash interface running in a regular browser. Uses The Object Machine as the component environment and Flash Sandy as the user interface engine.
Game-engine for windows- and unix-systems. Supports shader, scenemanagment, interface to the common render-apis, basic tools and a scripting support.
SandApple-PRT is open-source library for working with precomputed radiance transfer (PRT) using spherical harmonics (SH).
A simple 2D (2.5D) OpenGL graphics library, for creating GUIs, in the same style as Clutter.
Straylight is a geometry visualization system which is tightly integrated with the Geomatrix geometry engine.
