Openscenegraph Quick Start Guide : A Quick Introduction to the Cross-Platform Source Scene Graph API

This book is a concise introduction to OpenSceneGraph (OSG)-the open source, cross-platform scene graph application programmer interface (API). OSG plays a key role in the 3D application software stack. It's the middleware above the lower-level OpenGL hardware abstraction layer (HAL), providing extensive higher-level rendering, I/O, and spatial organization functionality to the 3D application.
