VRML 2.0 Group Concepts

• Group nodes can hold many other nodes, associating them in some fashion
• The list of grouping nodes is:
  • Anchor
  • Billboard
  • Collision
  • Group
  • Transform
• Strictly speaking, all nodes in the scene should be children of grouping nodes although most browsers currently ignore this .
• There may be more than one scene graph in the scene however.
• Typical syntax is:

<Grouping Node> {
       children [
            <other nodes>
       ]
       <field>
       <field>
         .
         .
         .
}
