Cool...I see...the WakeupOnElapsedFrame sounds most like what I was doing
with VRML (i.e. after each frame, update all objects, etc.)
So this processStimulus method is called by Java3D...does this mean that I
should make an object than extends javax.media.j3d.Behavior pass a
wakeupOnElapsedFrame to it's wakeupOn method, and then do all my updates to
all my objects in the processStimulus method, and then Java3D will
automatically re-draw the screen after the processStimulus method is done?
What I'm getting at here is that I want to update the positions of multiple
objects (transformgroups), but I don't want Java3D to update the screen
until all of the my objects have been updated. Does this make sense?
Thanks
Mike
