I looked at the license (http://java.sun.com/products/java-media/3D/java3d-license.txt)
and it does not clearly give us the right to distribute the Java3D jar and

Hello Guillaume,
To answer your first question, the way that I've used to get the menu items
to appear on top of the Canvas3D is to use a java.awt.MenuBar instead of a
java.swing.JMenuBar and use Menu and MenuItem instead of JMenu and
JMenuItem.
This is because the Canvas3D is heavyweight and th

I saw similar exceptions on with jdk1.3 beta_refresh on Solaris they have been
fixed in the next release.

Hi,
In order to have things more practical I join some source code (It is
derived
from one Java3D demo and is quite bad at that time).
The application I want to design is a scientific visualisation application.
Roughly
we want to visualize a large number of triangles (millions) and put colors

Agreed. The problem is most of the content on j3d.org has not been

In Java palance, the 'void' return means the result comes back in 'this'
(the object on which the method was called).

Be careful. Have a friend sit with you the first couple of times.

ATI has had hardware acceleration on the Rage Pro chips with some of their
beta drivers and I believe the current release drivers do support it now.
It's a bit tricky though because they don't support hardware acceleration at
all color resolutions with the Rage Pro. For example, in the past, only

Justin,
True the j3d.org site has install procedures (I know I've seen them
somewhere) but they need to be one of the FIRST things a first time
visitor sees! I just looked and couldn't find it on casual glance. I
found it under "Running Java 3D" and then it wasn't under "Requirements

The only
solution I found to this problem was to use a
Transform3D. The following code

is parallel to the x axis
but passes through y = 1, so I used an AxisAngle4f to create

don't the basic operators on the tuple objects return self rather than

I had the mode set to GEOMETRY and each object had its own Appearance

done a bit more fiddling with the program, and it seems that if I

the problem disappears. If

Hello Thijs!
Whatever attribute you change on the live object,
you should set this capability on it's appearence.
in your case I think you need to do the following:
Appearance look;

.
look.setCapability(Appearance.ALLOW_POLYGON_ATTRIBUTES_READ);
look.setCapability(Appearance.ALLO

Two possible reasons:
1) Do you use USE_BOUNDS or USE_GEOMETRY pickMode?
Try using USE_GEOMETRY, it will give you better presission
in piking.
2) Do you use the same appearance (or Material, or Coloring attributes)
for diffrent objects? In that case if you change values inside one of
