An Anchor node creates a group that acts as a clickable anchor where every child node in the group is displayed, and clicking one follows a url to another scene or another Web link. An Anchor can also bring the user to another Viewpoint location in the scene. A description field names each Anchor so that the user knows its purpose.

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