Thommas,
I can only guess you have a lack of z buffer precision in your particular scene.
This can depend on both your scene dimensions and parameter and the
graphics hardware.
Check that you have set the backClipDistance to the
distance of the furthest object in your scene and that the

John,
Q: what precision of numbers for z depth is passed between the graphics card and
Java3D: single precision floats? The reason I
ask is that if J3D is restricting itself to
single precision then there is not enough precision to handle the range Thomas Auinger
required for his planets while
We use that technique in several places right now and have found there to be
a performance hit also. The biggest hit is sliding the cloud textures, so
much so that we now move the clouds less frequently than we would like.
Does anyone know if this transform is being done on the 3d card or if Java
We are having a setTextureTransform performance problem in our GDC demo.
We are setting 10 different texture transforms for about 200-300 vertices.
The code is simple:
texTrans.setTranslation( new Vector3d( cur[0].getFloat(),
cur[1].getFloat(), 0.0f ));
myTexAtt.setTextureTransform( texTrans );

The closest that you can get to this is based on the viewpoint
information. Either use ViewpointEntry/Exit or Activation conditions. We

I want to do some behaviour controlled animation. I do not want it to
run when player looks in other direction - it is a waste of resources.

You might try using the detach method in the BranchGroup class, but I don't
know if this will work.

Hi. I have been out of this world for quite a long time. But the scenarios

possible Scenarios are:
a) Game development
b) Engine Development
c) visualization in

Yes, you can do overlays. No, you
can't really do them practically. You'll see your framerate diminish to
almost nothing. Java does not blt worth didly, yet. But there's

I'm new to Java3d, so excuse me if this has been answered before. Is there a way to do UI overlays onto the 3d screen? I'm starting to program a 3d multiplayer game similar to Everquest and Asheron's Call. Both of these games have the UI over the 3d screen.

I've looked at a few 3DS loaders, though none in depth. And I've written
one once, too, though in C++ for an OpenGL project. I think the Starfire
loader is the best one available currently.

Hi!
Good day! I am going to create a program that is the same as the Moleculeviewer found
in the Jdk1.2.2 or Jdk1.3 demo applets.
In my case, I would like to create an applet that enables users to combine molecules
to form a new compound. The program is limited to 8 molecules only.

Strangely enough, I couldn't find it either. But this page has a small
example:
http://java.sun.com/products/java-media/3D/forDevelopers/J3D_1_2_API/j3dguide/AppendixExamples.html
This page contains several other things, so you'll have to search for it.
I hope this helps some.

Thanks for your answer Darren ..
I tried to find in the docs about pickCanvas but nothing !!
Think, I don't have the adresses of all the docs and the examples ?
Thanks again for any help

Pretty cool...been waiting on this ever since I heard Intel and Macromedia signed a
pact some time back. The quality is similar to Blender and WildTangent. I think you
are looking at different markets, though.
I would imagine Java3D will lose out to tools such as Director, WT, Blender in the
