thank you all for the judicious answers. It was indeed only a problem of order of
transformation.
As a corollary, has someone ever used a mousewheel in a java3D app ? :) or is that too
machine specific.

In my project the user "orbits" around the object in the scene, always
looking at the object.
What doesn't work? I'm guessing that your object goes out of view.
That's
probably because you're only translating, not rotating to keep the z-axis
pointing directly away from the object you want to see. To do that uses a
little trig, or you can use the LookAt method.

Subject: [JAVA3D] View Rotation
Hi all, i am trying to create a HomeWorld style visualization, ie :
Rotation
of the camera around selected objects controlled via the mouse.
So i modified the mouse rotate behavior, attached it to the
viewingplatform
of a simpleUniverse.
In the behavior, i set translation to Origin, then perform an Euler
transform upon the viewingplatform's transform
and then translate back.
This doesnt work however and i would like some feedback. ( i hope it isn't
a
view_attach_policy or anything of the sort, otherwise i am
gonna shoot myself)
Thanks alot.
Hans
