This project, ioquake3 (or ioq3 for short,) aims to build upon id Software’s Quake 3 source code release. The source code was released on August 20, 2005 under the GPLv2. Since then, we have been cleaning up, fixing bugs, and adding features.

Our permanent goal is to create the open source Quake 3 distribution upon which people base their games and projects. We also seek to have the perfect version of the engine for playing Quake 3: Arena, Team Arena, and all popular mods.

Here are some of the great improvements that the ioquake3 engine brings you:

  • Ports to new platforms
  • Off-server data downloads (http redirection) via HTTP and FTP with cURL
  • OpenAL sound rendering allowing for surround (5.1 and 7.1) speaker layouts and generally improved sound

    quality. Especially on the Windows Vista Operating System.

  • Ogg Vorbis audio decoding.
  • In-engine VOIP support, with optional Mumble player-location support.
  • IPV6 Networking. We’re ready to frag on the net of the future!
  • SDL backend for the OpenGL context, window management, and input. This also improves portability.
  • 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 auto-completion
  • Persistent console command history
  • Improved QVM (Quake Virtual Machine) tools
  • Colored terminal output on POSIX operating systems
  • GUID System
  • Multiuser support on Windows systems (user-specific game data is stored in their respective Application Data folders)
  • PNG format support for textures
  • Numerous security fixes

Great engine "fix"/tweak project.
However SDL makes it very difficult/nearly impossible to implement OpenGL 4.2 on ioquake3 rendering code.

I think you have to own Quake 3.

Reply Good karma Bad karma0 votes

The download for the engine is on the website. It is open source, so you do not need to own Quake III.

you need to own Quake 3 if you wish to play Quake 3: Arena or Team Arena, if you wish to play a standalone game based on this engine you do not need to own Quake 3.

Does exactly what it should. Runs much better than the version from ID on linux, plays nicely with compiz and pulse audio and didn't break anything. What else could you ask for?
