In our tests, on Linux, XFree86 4.0.1, and a Voodoo 3 DRI driver, fog
density is proportional to window size.
In other words, if I resize a window down to, say 400x400 pixels, the fog
is so dense that I cannot see anything rendered in my environment. If I
resize up to around 800x800, it looks ab

Routes are not classified as behaviours. They are really co
Using the Text2D class, I've created a Text2D object as follows:
Text2D frontText = new Text2D("New string",
new Color3f(1.0f, 1.0f, 0.0f), "Helvetica", 100, Font.BOLD);
This displays OK. I now attempt to double the size of the text using:
frontText.setRectangleScaleFactor(2.0f);
I've waited all week to see any response to this posting, so in
desperation I figured I would mail it straight to some of the Sun
engineers. Can you please direct this to someone who can give me an
answer?

If you want to rotate about an arbitrary axis then you can do it by
accessing the geometry of the shape and using a standard arbitrary rotation
transformation on the individual vertices of the shape. Then set the
coordinates back into the shapes geometry.
Im not sure if J3D actually supplies a sta

Maybe im out a little deep here, but what about the DemoJMFJ3D demo
which projects a movie on an object using Java3D and JMF?

No, you're not off base. I've heard ppl at Sun saying that they plan on
integrating JMF interfaces into the MediaContainer in J3D. But as it
stands today, that interoperability does not exist. Plus, JMF is a big
chunk that I'm not really interested in forcing users to download.
Instead, we hav

to. However, I am confused as to

I am interseted in getting a copy of the MultiGeomApp.java

Thank you.

Hi Don,
the Spaceball is very similar to the Spacemouse.
You can find Java3D classes for the Spacemouse at
http://www.spacemouse.de/software/drivers/WIN-Java3D.html
I'm not sure if it works, but may be it does the job.
You need to install the COMM package to use these classes.

Hi Raymond,
The error message indicates that you are using the wrong constructor
when you create your RotationInterpolator.
You must use either

Did anybody try setting AlternateAppearance on a large scene?

many nodes will actually be under an AlternateAppearance node.
I think alot of time is being spent on juggling arrays from some

The loader class does not attempt to convert VRML interpolators to J3D
interpolators. If you want the interpolators to run you will need to use the
player which will give you a complete VRML event model.
Basicly the loader is time-zero, meaning you will get all the geometry and
looks but no event
