Groups

• The Group class is the most general-purpose of the group nodes

  • Has exactly one parent

  • Can have any number of children

• You can add, insert, remove, and get children in a group

  • Children are implicitly numbered starting with 0

  • Child rendering order is up to Java 3D!

• Java 3D can sort shapes for better rendering efficiency

The Group node object is a general-purpose grouping node. Group nodes have exactly one parent and an arbitrary number of children that are rendered in an unspecified order (or in parallel). Null children are allowed; no operation is performed on a null child node. Operations on Group node objects include adding, removing, and enumerating the children of the Group node. The subclasses of Group node add additional semantics.
