hello,
Can anyone please tell me if there is a transform matrix
associated with the PickRotateBehaviour?
PickRotateBehavior behavior1 = new PickRotateBehavior(BranchGroup,
Canvas3D, BoundingSphere);
I wanted to obtained the Transform3D Matrix and modified it..

I have no idea if this will work, but while you're waiting for a better answer,
you could try passing your KeyEvents on to

Thanks to all of you who try to answer my 'not so clear' previous message.
I'm not sure that I've explain my problem very well. I'll try to be clearer
this time...

Hello,
How can I apply a geometric transformation (rotation, translation and scale) in
a 3D object (for example, a cube), trigged by a AWT button instead of using the
mouse?
PS: I don't want to use the MouseRotate class.
Thanks a lot.

I don't develop under Linux (yet) so I have no solid experience to back

Hi Ingo,
Bug 4357974 (with a test program)
- Mouse behavior no longer work after replaceBranchGraph
is already submit for it
and we'll take a look at this before next beta release.
Thanks.

1) I would like to know, if someone has tried to use Java3D and the JMF, for
example to create a video texture and a PointSound from a JMF stream.
2) And I would like to know if Sun is planning to create an interface
between those two.

I read something in the Java3D forums (sorry - I'll have to search for the

Carolyn,
I don't agree with your implication that 100% CPU usage is necessarily synonymous
with 'poor performance'.
If you are using Java3D is such a way as to want it to render as many frames-per-second
as possble, then you would expect to see 100% CPU usage. This is typically a
scenario that o
Carolyn,
I've seen this CPU usage change as well. From what I can figure, if the

scene when the window needs to be redrawn. If the scene IS changing,
then J3D turns into a real-time renderer, drawing the scene as fast as

Hi !
The PointLight's attenuation does not seem to have any effect on the light.
Is this a problem of Java3D or is this just not implemented in many OpenGL

Has anybody got a working attenuated PointLight ?
