Volume of communication necessary for displaying moving images is minimized. When an object is moved on a client terminal (13-1), a message indicating the movement of the object is transmitted to a server terminal (11-1). The server terminal (11-1) transmits the message to client terminals (13-2 and 13-3). Each of the client terminals (13-1) through (13-3) stores a message table in advance to execute the message. According the message table, an image for locally moving an object (101) is generated and displayed. This novel setup transmits information about the update of an update objects composed of a plurality of sub objects each of which state is subject to change, in a minimum transmission volume. This, in turn, allows cooperative operations of the plurality of sub objects to be smoothly displayed in a three-dimensional virtual reality space shared by a plurality of users. <IMAGE> |
