Hello,
1)I posted a question on the Java3D perspective model the last three days.
The
persons that answered me have been claiming that the reason of my problem
is a bug in the keyNavigator but my problem happens even if I control
directly
the viewpoint transformation instead of having the keyNavigator do that for
me.
Is there anybody in the Java3D team in charge of the perspective projection
module that can answer my question?
2) Is there any way to draw Java3D graphics in a browser in the background
under the html text? This would allow me to do a dynamic background.
I wwould appreciate any comments
Thanks
Yohan

Dear Michael, and others,
I will take your advice and experiment with this modification of the
KeyNavigator,
however this is not our principal device. I actually detected the problem
with the
perspective projection in Java3D while I was wearing a see-through HMD
tracked
by an orientation tracker and a position tracker. These devices have been
calibrated
are reporting resonable results. Well, when I turn my head, so that I always
see
the real counterpart of 1 and 2 aligned, It is not the case with Java.
However, like I
said before, a rotation only is applied to the viewplatform. So this problem
is not
only related to the KeyNavigator.
I can attach a picture if needed to understand the problem. Please try to
experiment
with that and you will see. Place a cube in the world (let say in 0, 0, 0
and of size
2 on any side). and place the viewplatform in (1, -5, 0) so that one side of
the cube
appears as a line. If you only rotate the transform applied to the
viewplatform then
you should always see this side as a line. In my case it does not work this
way,
I see the side as I turn.
Any idea?
Thanks
Yohan
