Abstract
An interactive picture providing method comprising the steps of preparing, in a server, three-dimensional pictures of a virtual reality space from predetermined positions; supplying data of a position in the virtual reality space from a user terminal to the server via a network; providing a picture of the virtual reality space corresponding to the position from the server to the user terminal via the network; providing, from the server to the user terminal, a part such as a background of the picture seen from a predetermined position in the virtual reality space; generating, in the user terminal, another part such as a foreground of the picture seen from the specified position in the virtual reality; and compositing and displaying, in the user terminal, the picture generated in the user terminal and the picture provided from the server. According to this method, efficient generation of pictures is achievable, and a high-definition picture can be provided to each of the user terminals at low cost.

5. An interactive picture providing method which comprises the steps of:
-
preparing, in a server, three dimensional pictures of a virtual reality space from predetermined positions, each predetermined position having a predetermined visual point; supplying data of a position in said virtual reality space from a user terminal to said server via a network; providing a picture of said virtual reality space corresponding to the position from said server to said user terminal via said network; dividing said virtual reality space into multiple partial worlds in such a manner that objects having a high probability to cause an interaction are grouped together within the same partial world; providing, from said server to said user terminal, a picture of a partial world containing grouped together objects seen from a predetermined visual point outside of the partial world containing grouped together objects; and generating, in said user terminal, a picture corresponding to the specified position supplied from said user terminal, in accordance with a deviation of the specified position from the predetermined visual point.
