Action Gear — The Action Quake 2 Accessories Archive, by MarlPoro

"The site was founded 7th February 2005 to serve the players of Action Quake 2 — the greatest game of them all. Here we provide all kinds of material to help the players make their gaming experience even more enjoyable, you can see everything we offer at the moment in the left-side menu. Remember — there is always new stuff coming, so pay us a visit every now and then :-) In matter of fact, the project was started already in year 2003, but it drained out cause of lack of interest. If you remember 'Action Adrenaline', then you'll know what we're talking about. What-so-ever, now we're here to finish the job. And for all of you developers: Please share your work, because it keeps this scene fresh and more alive."

Chaos Quake 2 Mod — Chaotic Maps, by Ilya Mikhajlov

"Quite a few years have passed when maps were made for the network component of Quake 2 Chaos. It seems that everything, the game is hopelessly outdated, but no - even now, during the break of working days, it is possible to get a portion of the crazy adrenaline in the slaughterhouse under the modification for the legendary game — Chaos. The OpenGL engine, new textures, a crazy arsenal of weapons and fun bots give the game a chance to run to this day. Well, if there are like-minded Old Believers for a network game … In this blog, over time... screenshots and descriptions of all the material that has seen the light here will also be presented."

The G3D Innovation Engine, by Morgan McGuire — 3D Player Models for Quake 2

"The G3D Innovation Engine is a commercial-grade C++ 3D engine available as Open Source. G3D supports hardware accelerated real-time rendering, off-line rendering like ray tracing, and general purpose computation on GPUs. Its design emphasizes rapid prototyping and innovation, particularly of rendering and game algorithms. G3D provides a set of routines and structures so common that they are needed in almost every graphics program. It makes low-level libraries like OpenGL, network sockets, and audio channels easier to use without limiting functionality or performance. G3D is a carefully designed, feature-rich base on which to prototype your 3D application. The contributors span the graphics industry. The engine is primarily maintained by Morgan McGuire, Zander Majercik, and Josef Spjut at NVIDIA, Corey Taylor, and Michael Mara at Stanford University & Oculus Research. It includes contributions from professional game developers, CAD and DCC developers, students, industry researchers, and professors."
