Hmmm....
I use the OrbitBehavior in one of our utility programs. As a test I created
a button which did this:
void jButton1_actionPerformed(ActionEvent e) {
Transform3D t = new Transform3D();
t.lookAt(new Point3d(100,0,100),new Point3d(0,0,0),new
Vector3d(0,1,0));
t.invert();
vp.getViewPlatformTransform().setTransform(t);
}
The setup code was like this:
orbit = new OrbitBehavior(canvas);
orbit.setMinRadius(20);
orbit.setSchedulingBounds(new BoundingSphere(new
Point3d(0.0,0.0,0.0), 2000.0));
u.getViewingPlatform().setViewPlatformBehavior(orbit);
Transform3D t = new Transform3D();
t.lookAt(new Point3d(100,0,100),new Point3d(0,0,0),new
Vector3d(0,1,0));
t.invert();
vp.getViewPlatformTransform().setTransform(t);
And it works fine. After I press the button the view resets and rotations
and scale work fine after that.
Maybe the secret is this line:
u.getViewingPlatform().setViewPlatformBehavior(orbit);

Subject: [JAVA3D] Resetting OrbitBehavior
Just started playing with OrbitBehavior. Is there an (easy) way to
reset the view once you have orbited/translated into nowhere? I tried
doing a ViewPlatform.setNominalViewTransform(), which brings things back
into view, but OrbitBehavior remembers his last
translation/rotation/zoom settings and restores them as soon as you
start rotating again.
