ioquake3 is built upon id Software’s tech 3 game engine. It is an open source project that aims to clean up the code, fix bugs and to add new features.
Usage
ioquake3 is released under the GPLv2 license, and a number of games have been released using this engine. A more detailed list which also includes products using the proprietary license is located here.
Additional comments
id’s next iteration of their game engine, tech 4, is expected to be released under the GPL license in 2010.
Skeletal animation
ioquake3 doesn’t have skeletal animation in its true sense. Instead, it relies on MD3 meshes. The animations contained in an MD3-file are vertex based.
This can be seen as a draw-back compared to skeletal animation, and is worth pointing out.
Benefits
ioquake3 along with id’s tech 3 have proven to be a reliable, high-performance game engine.
Bottom line
ioquake3 lacks support for Skeletal Animation. Therefore, it is not suitable for our work, although it has some very nice benefits.
