Abstract: A technology for improving the reality of images created by computer graphics. A modeling unit performs basic modeling on objects. An object classification unit determines the presence or absence of target objects of coordinate transformation. If there is any target object of coordinate transformation, a coordinate transformation unit performs coordinate transformation on the target object of the coordinate transformation. An object adjustment unit adjusts the positional relationship between the object given coordinate transformation and objects given no coordinate transformation, thereby reflecting the positional relationship between the objects before the coordinate transformation.

Abstract: In the distributed processing system, a user terminal receives an event information generated in the other user terminals and transmitted from a server. During a period that the event information is transmitted in a network, a model in a processing server becomes already different from a model in the user terminal. Then, a state change compensation portion (210) continuously changes a state of a model processed in a processing portion (208) so that it becomes the same as the state of the model in the processing server, whereby an influence of delay generated by a communication can be reduced.
