ioquake3 (or ioq3 for short; formerly known as icculus.org/quake3, which also used to be the URL of the project's website) is a game engine project which aims to build upon id Software's Quake 3 source code release. The source code was released on August 20, 2005 under the GPL.

The project's goal is to create a bug-free, enhanced open source Quake 3 source code distribution upon which new games and projects can be based, as well as an improved version (in relation to the original binaries) of the engine for playing Quake III: Arena, the Team Arena expansion pack and all the popular mods.

While the PunkBuster anti-cheat software is not supported (it is proprietary software), the security level is increased thanks to the bugfixes which are not present in the original executables.

Ioquake3 has been the basis of several id Tech 3-derivative games, including both stand-alone game projects, as well as former Quake III modifications exploiting the opportunity to become stand-alone thanks to the source code release. Examples include OpenArena^[1], Tremulous^[2], Urban Terror^[3] and World of Padman. There are also other engines based on ioq3, such as Evolution Q3, a Star Trek: Voyager: Elite Force engine recreation project or OpenMoHAA.

SDL backend for OpenGL context and window management and input
Anaglyph stereo rendering (for viewing with 3D glasses)
Full x86-64 architecture support
Rewritten PowerPC JIT compiler, with ppc64 support
Compilation with MinGW and cross-compilation for Windows for Linux
Improved console command autocompletion
Persistent console command history
Improved QVM (Quake Virtual Machine) tools

PNG format support for textures
Numerous security fixes

History

Contrary to what the name might suggest, the ioq3 project was not started by Ryan "Icculus" Gordon, but by Zachary "zakk" Slater, shortly after the release of the original Quake III version 1.32 source code release by id Software. Icculus actually maintains only a mentor role and provides some of the web services necessary to run the project, namely the mailing lists and the SVN repository.
