 Interacting with VRML objects

Hi,

I have basic knowledge of vrml and  Java.
i.e in VRML, I know how to create various primitives - cylinder, cube,...

What I would like to learn now, is to how
to interact with VRML primitives.
A good example is in the following location
http://www.*-*-*.com/

In the above model, angle, height, etc of various components can be
changed by simple drag operation in the accompanying windows below.

It looks like they have done this with Java.
If any one can tell me how to do this in Java with a simple example
OR point me to a location where I could find tutorials on this kind
of topics, I would be very greatful.

REgards,

Thiru

Thiru,

The interaction is doen within VRML, with JavaScript (really ECMAScript),
Java, or some combination of the three.  There are several sources that
describe the interaction.  First there is the VRML spec at
http://www.vrml.org/.  Bob Crispen has a wonderful FAQ that answers some of
your questions.  I maintain a page of VRML examples.  Bob's page is linked
from mine.  Mine is at http://www.realism.com/vrml/example.html.

There are also a number of other sources including web based tutorials,
books, and classes.  Digital University offers an on-line class that has just
started.  I am the instructor.  You can sign up at http://www.digitaledu.com/

Since you like that example, why not just take a peek at how _they_ did it?

The *.wrl files, etc., are all stored (very temporarily) my Win95's
Temporary Internet Folder.  Might work like that one your system too, right?

It's a hidden directory, of course.
