The topic of how Java 3D 1.4 will evolve, and what it will eventually
look like is not simple. Since Java 3D 1.4 is going though the major
specification request process, the look of Java 3D 1.4 going into
the expert group may not look the same once the expert group releases
the specification into public review. In terms of extensibility, we
are looking at supporting a number of the things you mention below.
If you are at JavaOne this week, and you want more information on 1.4,
come to the BOF on Wednesday evening. I will be presenting on the topic.
Also make sure to come to the Java 3D 1.3 session on Wednesday afternoon.
