'
' This example demonstrates how to find groups under the
' scene root or under a specific model given the
' following structure:
'
' Scene_Root Model Group
' + RootGroup *
' + ChildModel *
' + ChildGroup *
' + AnotherChildModel *
' + AnotherChildGroup *
' + GrandChildModel *
' + GrandChildGroup *
' ===== =====
' 3 4
'
' NB: The Model.Groups property has a limitation of only
' getting the immediate children of that model
' (whereas you can get every all models in all
' generations with the X3DObject.Models property).
