Detailed Description

Index that lets you look up the OSG components that comprise a given Feature. Given the Feature ID, this index will return a set of Geode, Geometies, and PrimitiveSets that make up the feature.

Use a FeatureGeometryIndexBuilder to create an index. Typically you can then attach the index to a node in the scene graph that you used to create the index.
