Detailed Description

This class is used for integration of the ESG with the OSG library. OSGAdapter contains methods that define interface for available oprations over the OSG library. Most of these methods are just abbreviations for the concept of explorers, i.e.. methods like rayIntersection() just instantiate appropriate explorer internaly and then returns the explorer's results.
