1. A method of generating a new path to a destination node in a virtual environment comprising a plurality of nodes, the method comprising:
- storing nodal information identifying one or more nodes associated with a previously created path to said destination node;
dynamically reconfiguring the topology of the virtual environment to define a start node for said new path; and
processing said stored nodal information to determine the new path to said destination by including at least one node of said previously created path.

Abstract
A method of generating a new path to a destination node (29G) in a virtual environment comprising a plurality of nodes (29A-G). The method comprises nodal information identifying one or more nodes associated with a previously created path to said destination node, dynamically reconfiguring the topology of the virtual environment to define a start node (29A) for said new path, and processing said stored nodal information to determine the new path to said destination (29G) by including at least one node of said previously created path.

14. A method of generating a return path to a portion of a previously created path in a virtual environment, wherein a user is able to be automatically navigated along the previously created path from a start node to a destination node, the virtual environment supporting the ability of the user to switch at their own volition from an automatic navigation mode along said previously created path to a manual navigation mode generating a second path which deviates from said previously created path in said virtual environment, the method comprising:
-
storing information identifying said start node, destination node and any intermediate nodes of said previously created path in said virtual environment;
dynamically reconfiguring the topology of the virtual environment to define a second start node at the point where said second path terminates; and
processing said nodal stored information to determine a return path from said second start node which intersects said previously created path at a re-entry node. - View Dependent Claims (15, 16, 17, 18, 19, 20)

22. A system arranged to support the generation of a new path to a destination node in a virtual environment comprising a plurality of nodes, the system comprising:
-
means to store nodal information identifying one or more nodes associated with a previously created path to said destination node;
means to dynamically reconfigure the topology of the virtual environment to define a start node for said new path; and
processing means to process said stored nodal information to determine the new path to said destination by including at least one node of said previously created path. - View Dependent Claims (24, 25, 26, 29, 30, 31)
