Hi there,

I would like to translate and zoom some spheres I put in my universe.

I used mouse behavior class PickTranslateBehavior and PickZoomBehavior.
Every thing is fine. However, when I add an OrbitBehavior to the
ViewingPlatform, the behavior of the PickBehavior classes is overridden
by the OrbitBehavior one. In other words, I can not translate and zoom
my spheres without moving the whole graph.

My question is: is it possible to tell the system to apply
PickTranslateBehavior, when I click on a sphere, and OrbitBehavior
otherwise?

Thanks a lot,
Marco

My code:

// add orbit behavior to ViewingPlatform
OrbitBehavior orbit = new OrbitBehavior(canvas,
OrbitBehavior.REVERSE_ALL );
BoundingSphere bounds = new BoundingSphere(new Point3d(0.0, 0.0, 0.0),
100.0);
orbit.setSchedulingBounds(bounds);
viewingPlatform.setViewPlatformBehavior(orbit);

....

Sphere sphere = new Sphere(0.10f,
Sphere.GENERATE_NORMALS | Sphere.ENABLE_GEOMETRY_PICKING,
sphereAppearance);
