[JAVA3D] picking from the specified canvas

[A. Murat Tanyer]

Hello all,

I wrote a class for my picking application. I have a tabbed pane with 3
tabs and on each tab I have different canvasses. I want my code select
objects from one of the canvas. So I pass one of the canvas name in my
code. But in reality, the code selects the objects on all of the
canvasses. What is the reason for this? How can I correct this?

Thanks for any help.


//MY CODE
public class MousePickBehaviour extends MouseClickedBehaviour
{

           PickRay ray = createPickRay(canvas_vr, x, y);

           SceneGraphPath sgp = Solid.pickClosest(ray);
           //number of objects in spg returns 1
           if (sgp!=null)
           {
               Node object = sgp.getObject();
               ...// rest of the code
           }

   private PickRay createPickRay(Canvas3D canvas_vr, int x, int y)
   {
       Point3d eye_pos = new Point3d();
       Point3d mouse_pos = new Point3d();

       canvas_vr.getCenterEyeInImagePlate(eye_pos);
       canvas_vr.getPixelLocationInImagePlate(x, y, mouse_pos);

       Transform3D motion = new Transform3D();
       canvas_vr.getImagePlateToVworld(motion);
       motion.transform(eye_pos);
       motion.transform(mouse_pos);

       Vector3d direction = new Vector3d(mouse_pos);
       direction.sub(eye_pos);

       return new PickRay(eye_pos, direction);
   }
}
