Re: [JAVA3D] reg:problem with mouse zoom

[Mike Pilone]

Quickly looking at the OrbitBehavior API it looks like it only supports a
min radius and not a max.

The image is probably disappearing because it is passing through your back
clipping plane. If you want more control over the movement you may have to
write your own behavior.

Subject: [JAVA3D] reg:problem with mouse zoom

Hello,

I am having problem with mouse zoom in my application.

The problem is :

When i am trying to room the image its zooming well but after certain point
the image is disappearing i.e i can't able to see the image.

So i want to know how to control the zoom , so that i can zoom exactly to
the size of my boundingsphere.

This is the coading i am using . pls correct my mistakes and advice me how
to get rid of this problem.

public ObjLoad(String args[]) {

   setLayout(new BorderLayout());

 GraphicsConfiguration config =

 SimpleUniverse.getPreferredConfiguration();
  Canvas3D c = new Canvas3D(config   );

  add( "Center", c);

 BranchGroup scene = createSceneGraph(args);

 u = new SimpleUniverse(c);
ViewingPlatform viewingPlatform = u.getViewingPlatform();

viewingPlatform.setNominalViewingTransform();

  if (!spin) {
OrbitBehavior orbit = new OrbitBehavior(c,
    OrbitBehavior.REVERSE_ALL | OrbitBehavior.STOP_ZOOM);


    TransformGroup objTrans = new TransformGroup BoundingSphere   bounds =
new BoundingSphere(new Point3d(0.0, 0.0, 0.0), 1000);

orbit.setSchedulingBounds( bounds  );

    viewingPlatform.setViewPlatformBehavior(orbit)  }
 u.addBranchGraph(scene);


 }
public void destroy() {

 u.removeAllLocales();

 }
