PROBLEM TO BE SOLVED: To enable to search and distribute time-space models at high speed in response to a request from a user in a time-space model distributing system implemented in a network.;SOLUTION: In a model distributing server 1, from model information of a distribution target, geometry information and scene information are generated in a scene generator 11 and index information is generated in an index generator 12, and then stored in a model database 16. A model display client 2 generates distribution request information in a distribution request defining portion 22 by using a point of view and time information which are displayed and indicated. The model distribution server 1 distributes non-distributed geometry information which is not shielded by request point-of-view information, and display control information thereby by using the point of view of the distribution request information, the time information, the distribution point-of-view and the time information. The client 2 sets the geometry information of an addition-instructed face ID as a display target and deletes the geometry information of a deletion-instructed face ID, and controls the display in a display controlnortion 23.;COPYRIGHT: (C)2003,JPO
