Hello,
I have the following very urgent question:
How can I get the heading, pitch and bank out of a quaternion or a matrix,
which I do need for the KBKeyFrame-Class which I want to use instead of
TCBKeyFrame whose corresponding TCB..Interpolator does not use cubic
interpolation for orientation.

Ok, for the article - clarification point - even if you are have
USE_GEOMETRY,
Due to popular demand :) I took a bunch of the stuff over the last few
days about collision detection in J3D and wrote up a document about it.
It's relatively high level, but I hope that is will be useful enough for
the likes of Karin to take a peek at and help in their decision making
process.

You could export to 3DS format and use our loader. Our loader does

Have you tried connecting an external monitor to the Toshiba laptop? It

Depending on the complexity of your application and the quality you want to

right. Also, center distance calculations might not be good enough if you

Hi Harry,
What problem did you encounter when using v1.2.1 beta ?
Please send us a test case for investigation. I don't know
if there is workaround for this without using v1.2.1 beta2.
Thanks.

This optimization is not possible. Collision is a rendering independent
feature. It only depends upon the geometry in the scene graph. Imagine
someone walking backwards with the view platform. Rendering based
semantics would prevent a collision from being detected behind the viewer.

You will have to do something like;
Set the TransformGroup to the original Transform3D values
or
Keep a copy of the initial Transform3D of that TransformGroup and when u reset the
button just do tg.setTransform(t3d)

Okay, let's try this from a different angle. I'm hearing basically
two separate complaints. First, the implementation is buggy. Second,
the documentation lacks much of the philospohy or architecture behind each
feature.
So, why is the implementation buggy. If you look at the history of

I believe I misread this. Never Mind. :^)

This is a pretty good synopsis of the overall features of the different
collision alternatives. I have a couple of comments on this. I'm sending
this to the interest list because some of the comments relate to behaviors
in general.
Behaviours Background
I was reading the OpenGL forum and they recommended disabling VSync in the
driver. I changed mine to "off always" and my framerate jumped up
considerably in my application.
I wonder what else is worth tweaking in the drivers

Great, thanks. I pull these in
Yes, this is correct. The BehaviorScheduler is bounded by the Renderer
threads as well as the other way around. It is just for the reasons
that you mention. At one point in time (early 1.1 developement), we
let the BehaviorScheduler run wild, and had some really cool effects. :^)

Is this particular to a given card/driver? If not, mind sharing some
info on where to go to set these
Definitely add it to the FAQ. For the longest time I was convinced that
Java3D was not properly synching itself with the monitor. It turned out the
VSync option was disabled by default for my driver!
One thing to be aware of when disabling VSync, you may get better frame
rates, but your scene may
Justin, as far as I know Voodoo drivers have had this option for a few
years now (I haven't been able to find a way to do this on Matrox
cards). It is driver dependent. NVidia's detonator drivers allow you to

Thanks for your help!
Can I ask if there is a possibility that I can get the parent of the viewplatform and
modify the rotation component of the set transform3d.I want to simulate a set of
buttons that
show a rotation along the x and y axes by modifying the transformgroup above the
viewplatfor
Yes,it is a very interesting topic for Java3D to tackle on. And hope we be able to
make our own simulator and finish our course!
