Hi!
Just wondering, what is the use of pickIntersection.getClosestPoint()?
pickIntersection.getClosestPointVW() gives me the intersection point in
world coordinates.
I have tested it and it is working. But the other one tells me some
coordinates which
are located somewhere but not in the near of

Hi,
I have written code for saving the scene to my own file format. In this file I save
all the vertex and the material of the shape3d.
When I load the scene if I set a material to the shape3d appearance, the object
disappears. What is happening?
I think all is working fine if I dont set the

Java3D itself does not have a software emulation layer, it relies on
OpenGl or Direct3D. If the underlying operating system does not have
either of these then you won't be able

Is it possible to develop a Java 3D application that runs on mobile devices such as

Hope someone can help me with this. Thanks.

Hi Fergus,
Create a behavior that wakes up on WakeupOnBehaviorPost. Then whenever your
program gets a request from your stream to update the scene graph, wake up
your Behavior by calling its postID() method. Your Behavior will wake up and
execute processStimulus(). If you define your Behavior's p

Good morning ,
Given an object's whose maximum and minimum coordinates you know how do you:
a. center it on the screen?
b. Make sure that it is "contained" in the 3D canvas?
Any help greatly appreciated!!!

Hi
Guys
Is there a way
i can know when the alpha finishes ? this is of course
without using the
finished() method as i need the alpha to do something
when it is done.
do i have to extend
alpha for this ?

Perhaps I'm just being dense, but I get the impression that Java3D
Behaviors and Interpolators are good for doing things which you know the
'shape' of in advance, and/or things which are triggered by user
interaction, but not so great if you want to do something like read a
stream from a network a
No, not in Java 1.3.x. Java 1.4 has support for fullscreen. This is an AWT
limitiation, not a Java3D one. I say that because of OpenGL.
Java3D has support for fullscreen exclusive mode if you use the DirectX
runtime and the -Dj3d.fullscreen=PREFERED
The OpenGL version doesn't have any equivela
Remember, you can always give the VM more memory to work with by using
the -Xmx# parameter. This increases the heap available to the VM. I don't
know the default value the VM receives when it starts up without the -X
param, but it's a modest amount. Try this:
java -Xms256
Assuming, of course
No, only BranchGroups may be added or removed from a live scene.
You can add a BranchGroup to another BranchGroup.
So, assuming you wanted to add a Shape3D to a live scene.
Your shape is represented by /S2\
Your current live scene could be represented by

Well not quite. Normaly the VM starts up default with a specified memory

setting first. To the original

Riana,
When I suggested on comp.lang.java.3d that you look at the Java3D Interest
group as a resource, I didn't expect you to ignore the other suggestions I
gave you.
Please read the Chapter 0 and Chapter 1 of the Java3D Tutorial at

Someone posted this code (Virtual.java) awhile back to the list.
UniverseBuilder.java was an example from The Java3D 1.1 API Specification.
I don't see it in the 1.2 specification and I don't have a copy of it here.
But it's basically the same thing, just broken out into ColorCube and

Hello,
yes, I'm using a high resolution (1600x1200).
But many applications support it, only Java3D doesn't.
So I wondered how many graphics card memory is used by Java3D.
(roughly calculating, 1600x1200x16bit = 4MB; the graphics card has
32MB; even with double buffering there should be plenty of

But if I change my desktop resolution to 1024x768 it works fin
