Detailed Description

This query object will search the specified scene graph for all the OSG components that comprise a particular Feature ID. It searched the graph for a UserData structure containing a FeatureGeometryIndex. When found, it searches that index for the Feature ID. If found, it returns the record; otherwise it continues searching.
