Hi,
I've used j3d for a few years but had no opengl/3d graphics experience
prior to that.
I came across the screensavers at www.voodoolights.com and I was wondering
if anyone had thoughts about:

hi all
I've tried to make a java3d program with key
behavior.
When arbitrary key pressed, 3D object rotate 5
degree.
So, I used the Robot class, this is a role to generate key
event, to make 10-time key event(press).
But the 3D object directly rotated from 0 degree to

Thank you for your instruction. I checked the PureImmediateStereo.java file

My graphic card does support the stereo. I am not perfectly sure whether

Hi Artur,
You can store 'normal' java serialized objects in the userData structure
of scene graph nodes or in the BranchGraph user data or in
the file user data so you should be able to achieve what you want.

Ok, then I have another question about serializing objects. I understand
that if I refer to other scenegraph objects, I need to use
SceneGraphObjectReferenceControl. This is more or less obvious. But it
works only with subclasses of javax.media.j3d.SceneGraphObject.
I have an animation behavior.

Hi Artur,
Problem 1 below can be resolved by setting the class loader used by
the scene graph io api. Use setClassLoader in SceneGraphFileReader and
SceneGraphStreamReader.
As for problem 2, you should be able to use a property
System.setProperty("j3d.io.UseSuperClassIfNoChildClass", "")

Very nice texture mapping. It looks more realistic than others. and the
speed in the moving is similar as my program has. Imagine that it runs at 5

While I work for Sun, I don't speak for the Java3D team.

are included in J3D.

This means that nvoglnt.dll was compiled without debugging info and jvm

I'm thinking about creating interface similar to Loader, but working in
other direction. Having such interface would allow writing basic
