Raven released both Jedi Knight 2 Jedi Outcast and Jedi Knight 3 Jedi Academy sources under the GLP licence after Lucas Arts got shut down by Disney.
SourceForge links:
Jedi Academy sources -> http://sourceforge.net/projects/jediacademy/
Jedi Outcast sources -> http://sourceforge.net/projects/jedioutcast/
And there is already a project to upgrade the sources (mainly via backporting ioQuake3 they said) in GitHub called OpenJK
Link -> https://github.com/Razish/OpenJK
ioquake is also working on their own versions of each:
Jedi Academy - https://github.com/ioquake/jedi-academy
Jedi Outcast - https://github.com/ioquake/jedi-outcast
Sweet! I hope they can organize a grouped effort fast instead of having so many forks.
I'd have loved they (Raven) had released it sooner though.
One thing I was thinking about, ID Tech 3 derived projects never used OpenGL 3.x right? It would be nice to inspect such project with a modern OpenGL approach.
Yeah, apparently I'm the only one who has commited to the jedi-academy repo so far. I know ioq3 was talking about cleaning up the code (switch to CMake and remove Xbox-specific code), and then backporting ioq3 and iodoom code.
Yes, I believe id Tech 3 uses OpenGL 1.2 and id Tech 4 uses 1.5 since they were both released before OpenGL 2 was released (although sadly, Doom 3 was released just a month before OpenGL 2.0 was announced 
).
Yep I was aware that id tech 3 uses OpenGL 1, seems like Jedi Academy references a SGI implementation :D (for that matter, how do you compile that? Ask SGI nicely for 15 year old libraries and headers?). Though I didn't knew id tech 4 used OpenGL 1.5, I thought they had at least OpenGL 2 going.
Coincidentally, Doom 3 running on a 12Mb Voodoo 2 http://www.3dfxzone.it/enboard/topic.asp?TOPIC_ID=1462 hahaha
I was asking about recent open source derived projects, not original id tech 3 itself. No one upgraded it to OpenGL 3.0 right? At least I don't recall any project like that.
No, I don't think anyone has managed to get a id Tech engine up to OpenGL 3.X yet.
Although, I believe the renderergl2 sub-project in ioq3 uses is an alternative renderer that uses OpenGL 2 rather than 1.
