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. </p> <p> These X3D scenes are adapted directly from the <a href="http://www.wiley.com/legacy/compbooks/vrml2sbk/toc/ch28.htm" target="_Vrml2Sourcebook">original VRML 2.0 Sourcebook chapter examples</a>.
