Uair is the working title of the game framework that I've been working on for longer than I'd ever admit. It's gone through many incarnations (I even ported one version over to javascript) but has always been written C++ using OpenGL for rendering. The current version uses C++11 and OpenGL 3.3 and is nearing a useable stage.
The purpose of this project is to both give me a platform I am comfortable with in any future projects I might undertake, and as an educational tool so that I can better understand the lower level workings of such a framework (I feel using one of the existing great game engines out there would obscure some of the stuff under the hood which I would really like to learn). It is licensed under the zlib licence so that others might be able to learn from it too.
