I create the website osgHelp to share some of the basic knowledge of using the OpenSceneGraph library. I don’t work too much on the osgHelp website anymore, but once in a while I add some new content. I have recently discovered Unity3D and I really like this engine/framework, so most of my free time will be working on Unity3D.
