Detailed Description

Registry is a singleton factory which stores the reader/writers which are linked in at runtime for reading non-native file formats.

The RegisterDotOsgWrapperProxy can be used to automatically register DotOsgWrappers, at runtime with the Registry. A DotOsgWrapper encapsulates the functions that can read and write to the .osg for each osg::Object.

The RegisterReaderWriterProxy can be used to automatically register at runtime a reader/writer with the Registry.
