Thanks. That was what I need.
Maybe I should read the javadoc a bit more... ;)

Given a scene graph node (a shape3d, a Primitive, etc), I need
to know which is the total transformation (actually only the
translation, not the rotation) realtive to the origin applied over
this node.
This can help you to understand what I need: I pick an 3D object

I'm getting an java.lang.OutOfMemoryError in my program
after trying to add several thousands of scene nodes to
my scene graph. OK: "no problemo", I suppose it's not
possible to avoid such an error when you try to render
"too much" 3D objects. But I have some questions:

Hi all.
This is my question on a similar subject:
I would like to know how Java3D links to OpenGL.
I posted a similar message here in the list in April,
and Mauricio Vices reply to me (thanks, Mauricio),
but I still am not sure about how this works.
The question is:
I know I have at least 2 Op
Don´t be confused: I agree with you that Java3D is a
very well designed-implemented-documented API.
And sure: native windows render faster.
However, I can´t succesfully get such simple things as
popups menus over a Canvas3D or adding a Canvas3D to
a JInternalFrame in my MDI application.
I'll tak
I would like to know if the Java3D development team
has in mind to include a Swing, lightweigth component
for rendering in near releases of Java3D.
Canvas3D is good, but try to integrate it with a
Swing application
Thanks.
Does anybody knows if it is available the Java3D API Documentation
in Windows Format (.hlp) ?
Where?
Thanks.

I would like to know how Java3D links to OpenGL.
I know I have at least 2 Open GL renderers installed in my system:

When I run a game or a 3D benchmark (like 3DVillageMark)

That's my problem.
I want to rotate my 3D model using a RotationInterpolator.
It works fine, but while it's working, the CPU usage is 100%.
This is my interpolator code:

Dear Dr. Michael,
I recommend you the Java3D Api Specification, you can find it in
http://java.sun.com/products/java-media/3D/releases.html#spec_1_3
It is better than the Api Tutorial. Im sure you will clarify main concepts.
Maybe you have gotten it already. I don't know. I tell you because I

Please Sorry for my english!!
This is from Specification Java 3D:
The effects of transformations in the scene graph are cumulative. The
concatena-tion
of the transformations of each TransformGroup in a direct path from the
Locale to a Leaf node defines a composite model transformation (CMT) that
I've built a QuadArray which contains non-planar quads (quads
without all vertices in the same plane)...
...this is impossible in theory, so I guess Java3D internally
divides every quad into 2 triangles.
My questions are:
Is this true?
How are divided the quads?
Does it depend on the the order
Finally I have been able to put a background geometry into my scene.
I wanted to render some clouds in the background of my terrain scene.
I've got it using a Sphere of radius 1.0 as a background geometry,
flipping the normals, and mapping my "clouds.jpg" into the sphere:
Appearance app = new
I have not tested it, but I suppose this could work well for you:
public void processAWTEvent(AWTEvent[] events)
{
int x = ((MouseEvent) events[0]).getX();
int y = ((MouseEvent) events[0]).getY();
myPickCanvas.setShapeLocation(x, y);
PickResult pR = pickCanvas.pickClosest();
Thank you for your answer, but I was working yet with OpenGL version of Java3D and my
fog still doesn't work. My specific question is:
Is it necessary to add the fog leaf node to the scene graph?
or is it quite enough to do myCanvas.getGraphicsContext3D().setFog(myFog)?
or both of them?
Thank
I want to add fog to may scene, and I don´t know how to do it.
This is my code:
ExponentialFog fog = new ExponentialFog(150, 150, 180, 0.25f);
fog.setInfluencingBoundingLeaf(myBoundingLeaf);
fog.addScope(mySceneGraph.getRoot());
myCanvas3d.getGraphicsContext3D().setFog(fog);
