I have tried a new approach and it is looking better.
case1:
I am passing the 3D object to be dragged from DragTestCube into the
BasicDragging class which is the class where dragging is implemented.
Things are looking better now but there is always an offset. I am
using the Perspective lens.
These are the classes I am using. The ultimate purpose is drag objects
so in a room so the mouse positions and object must coincide.
case2:
Funniest thing is that when I am not using two classes and doing
everything in a single class there is no offset !!!!!!
Thats what puzzles me the most.
I am using Away3d 2.5.0. Drag3D class is in away3d.tools.utils.Drag3D

HERE EVERYTHING SEEMS TO BE FINE. But since I have to use it many
objects and I am developing as a part of OOP architecture I need to do
it in two classes.
