Examples of javax.media.j3d.Group

javax.media.j3d.Group
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.
