java3d question

I apologize if this is not the correct group to ask this question but
comp.lang.java.3d seems to be very unactive...

Here is my java3d question:
I would like to know how to change simple object properties.
E.g.:
I have a geometry.Box object. During the execution of the program (by that I
mean that the object is already live and compiled)   I would like to change
two properties of this box:
- color
- size

how can I do that?

thanks,
Saso Zagoranski

I don't know much about Java3D, but wouldn't it work just like any other
method call?

Sure :)
But you need to know which methods to call...

Java3D has a pretty complicated way of defining shape and appearance.
You don't have Box.setSize(...) or Box.setColor(...) methods...
(unfortunately :( ).

Well, you can find a *lot* of information about Java3D programming on
the Internet. Too bad for you I just cleaned my bookmarks (and removed
my Java3D section...)

Google this:
tutorial Java3D
First result:
<developer.java.sun.com/developer/onlineTraining/java3d/>

Thanks for the answer but I was hoping for a direct answer...
I did download and print out almost the entire tutorial published by sun and
couldn't
find that very simple information. It's true that I quickly looked at some
of the chapters because they
didn't seem to have what I needed and it is possible that it actually was
there and I didn't see it.

So... quick and direct answer anyone? :)

Sorry, no direct awnser, but this got me interested again. :)

I found out that you actually can't resize a geometry.Box :(
Neither can you resize any of the other primitives, such as:
Cone, Sphere, ...

I personally think that this sucks!
And to be honest... I'm not all that excited about java3d too. I've been
using
it for a few ws and I think that it's design is very bad... but that's
just me.

Saso, I update my 3D-stuff in a separate method, like so (it's for a
surface, not a box, but anyway..):

public void updateGeometry() {

// ...set new values for surfCoordBase and surfColorBase here...
surfaceQuadArray.setCoordinates(0, surfCoordBase);
surfaceQuadArray.setColors(0, surfColorBase);
}

Not sure how Java3D does the updating though, "behind the curtain" so to
speak (and there's been a couple of years since I wrote it)...
Cheers,
