These are classes that I am using.

This is one approach I tried. When I did like this I could attain a
dragging. But the approach taken is not correct.I am not able to
maintain lock on the object. Here I passed the object to be dragged
from one class into the DraggingClassUsingDrag3D. Then I made the
object follow the sphere which inturn is following the mouse.
