I recently released new version of Spin-X Platform sources to Sourceforge. Spin-X Platform is rather large multi-platform game code base (~200kLOC) containing game related code such as math/multi-processing/container/stream libs, light pre-pass renderer (DX9, DX11 & OpenGL), physics library integrations (PhysX, Bullet), extensible WYSIWYG world editor, etc. The platform has been built modularity in mind, and is made increasingly modular to make it easy to plug-in components that fit your team & project the best, or integrate your own proprietary components for the platform (e.g. a graphics renderer).
Here's also an overview video of the world editor demonstrating basic level editing, different asset editors and asset import pipeline for 3d meshes & textures: http://www.vimeo.com/25654850
The community website for Spin-X Engine has been launched at community.spinxengine.com. In addition to Spin-X Engine related stuff, there's also general game technology discussion forums and private forums for more experienced game industry pros that might interest some of you. You can also have your own blog, write game tech articles, build your sub-communities, promote your Spin-X Engine projects, etc. More info can be found here.
The first Spin-X Editor screenshots were just released!
"Spin-X Editor project has been committed to SourceForge and below are couple of screenshots of the editor. The development of the editor is progressing nicely, but there are still many things to do and improve, so stay tuned!"
