-Scenes are containers for other Renderables.  This is a base class that can't
-be instantiated.  Examples of available Scene types are SimpleScene,
-InstancedScene and OrderedScene.
+Container for other renderables.  Subclasses provide different ways of
+rendering the contents.
+
+All types of Scenes perform frustum culling on the contents, skipping
+renderables whose bounding sphere is fully outside the view volume.  If a
+bounding sphere cannot be determined, culling is not performed on that
+renderable.
+
+SimpleScene is a good default choice if there are no specific requirements.
