<p>Combining lessons learned from established scene graphs like

and Open Inventor, with modern software engineering methods like Design
Patterns, along with a great deal of feedback early on in the
development cycle, it has been possible to design a library that is
clean and extensible. This has made it easy for users to adopt to the
OpenSceneGraph and to integrate it with their own applications.
