Embodiments of the present invention provide functionality simulating the physical behavior of at least one object in a three dimensional (3D) scene that is divided into a plurality of zones. One such example embodiment comprises: providing at least a first zone and a second zone topologically adjacent, each zone having its own computing resource, providing an object located in one or both zones, and simulating the physical behavior of the object, the simulation being performed by the computing resource of each one of said first and second zones.
