Detailed Description

Callback used to implement the reading of external files, allowing support for paged databases to be integrated with IntersectionVisitor. A concrete implementation can be found in osgDB. Note, this loose coupling approach is required as osgUtil is independent from osgDB where the file reading is implemented, and osgDB itself is dependent upon osgUtil so a circular dependency would result from tighter integration.
