I'm a newbie for java3d. I'developing a degning tool with java3d, and
need to change the geometry frequently therefore. However, the 3d
result always shows the initial data only. Can someone give a hint,
what's the problem, and how can I solve it?

I was looking at some sample code QuickTime programming in Java that
makes use of:
net.java.games.jogl
This library seems to be depreciated by the newer version of jogl.
