Grouping nodes are used to group shapes to compose complex shapes.

  • The Switch node creates a switched group where only one child node in the group is displayed, children implicitly numbered from 0 and a whichChoice value of -1 selects no children.
  • Transform creates a group with its own coordinate system where every child node in the group is displayed.
  • Billboard creates a group with a special coordinate system that turns to face the viewer.

These X3D scenes are adapted directly from the original VRML 2.0 Sourcebook chapter examples. Also available: Introduction to VRML97 SIGGRAPH98 course notes.
