Grouping Shapes
BranchGroups
- A BranchGroup is a major sub-tree of the scene graph
- Can be attached to a Locale
- Can be compiled as a unit
- Can be included as a child of a group
node in another subgraph
- Can be reparented or removed at runtime
- Adding a BranchGroup to a Locale makes
the group live
- Once live, changes are constrained to those enabled
by capabilities
