I'm no expert but I did spend a fair bit of 'hobby' time last year
doing Java/VRML EAI on a little personal project. I'd say it's a good
place to get started, there is a lot you can do considering the some
what bolted together interface. You can get nice 3D stuff going very
quickly with VRML once you have the basics and with a bit of bodging you
can get some better control of that 3D stuff from Java.
But it is limited and you spend a lot of time working around the
interface rather then the interface working for you! You also can only
use Java 1.1 at the moment, which I found a pain as I wanted to learn
Java2 while doing this project and had a nice pile of Java 1.3 books
that I couldn't use. Plus it's a little kludgey as the VRML can only
talk to the JavaScript engine of the Browser which then has to talk to
the JVM of the Browser and then the program. When that works it's fine,
with occasional timing problems but normally does what it should.
I've now moved to writing a second version of that project in Java3D,
only been doing it for a month but already I can see HUGE new
possibilities that just couldn't work in EAI. I can also reuse all the
models from VRML but now I just can't code fast enough to do all the
ideas I have, as they are actually possible now!
As with any lower level approach to programming it is harder to get
things started but when you get it going there is almost no limit to
what you can do with it as you have complete control!
My needs are not complex 3D modelling or animation, but I do require
upwards to 1000 simple objects in the same scene with interaction and no
clipping. Plus full access to Java2 and the file system, which is just
so much easier without the browser and is more portable.
