Abstract:
A method of sharing a three-dimensional virtual reality space comprising the steps of:connecting a plurality of client terminals for displaying a three-dimensional virtual reality space, including a plurality of three-dimensional objects, to a shared server terminal for controlling states of the plurality of three-dimensional objects via a communication network;setting a plurality of local identification codes, each local identification code uniquely identifying each of the plurality of three-dimensional objects displayed on each of the plurality of client terminals; andcontrolling the states of the plurality of three-dimensional objects in the plurality of client terminals by converting on the shared server terminal the local identification codes identifying the three-dimensional objects whose states are to be controlled into a corresponding global identification code by use of a conversion table registered in the shared server terminal in advance,wherein the conversion allows the shared server terminal to use the local identification code of a three-dimensional object displayed within one client terminal and the corresponding global identification code to identify associated local identification codes, and wherein the conversion allows other client terminals to receive the associated local identification codes and associated update information and in accordance therewith update corresponding three-dimensional objects within the three-dimensional virtual reality space displayed on the other client terminals.
