*
Illustrate Viewpoint binding operations (in gory detail!) as described in Chapter 4 concepts. Scene design: a TimeSensor clock drives and IntegerSequencer for each t0/t1/etc. event, and a customized Script node sends bind/unbind events to the correct Viewpoint. Display the browser console to see occurrence of each event.

This program uses the
X3D Java Scene Access Interface Library (X3DJSAIL).
It has been produced using the
X3dToJava.xslt
stylesheet to create Java source code from an .x3d
