The 3D model represents a 3D VRML representation of the environment  with a 3D graphical avatar of the platform at its current location. It is possible to see the mobile platform avatar moving synchronously with the real motion.

The advantage of the 3D representation lies on the fact it is possible for the operator  to "watch" the scene from any viewpoint.

The 3D model of the environment cat be based either on CAD data or, more realistically, on the real world.
