Abstract: The present invention provides an image generation system and a program embodied on an information storage medium or in a carrier wave which can generate an image in real-time of an object that distorts in accordance with an impact position, with a reduced quantity of data and computational load. There is provided an image generation system which generates an image of an object formed by a primitive surface. It comprises an impact computation section (114) which computes an impact position at which an impact is imparted to the object and a distortion computation section (116) which performs computations for causing the distortion of the primitive surface in the vicinity of that impact position, to generate an image of the object formed by the primitive surface that has been distorted when the object has been subjected to an impact.

Abstract: Am image generating system and program which can generate an image in which the change of state in an object propagate with less amount of data and reduced load in computation is provided. The image generating system generates an aggregate object (600) which is formed by a plurality of elemental objects. Each of the elemental objects (610-1 to 610-9) has means (620-1 to 620-9) for holding its own state in its own state buffer (622-1 to 622-9), means (640-1 to 640-9) for monitoring the other elemental objects belonging to the same aggregate object, and means (650-1 to 650-9) for changing the state of that elemental object when the states of the other elemental objects having a predetermined relationship relative to the elemental object are changed.

Abstract: An image generation device and an information storage medium that make it possible to increase the virtual realism and dramatic effect of a shooting, game in an efficient manner. A plurality of objects such as target objects are set within an object space, and a hit check is performed on shots from 1P and 2P players and the target objects. First and second viewpoints for the 1P and 2P players are controlled and images as seen from those first and second viewpoints are output to first and second display screens, respectively. Although the viewpoints of the 1P and 2P players are the same in the prior art, they can be made different in this game. The first and second viewpoints move along first and second movement paths, and the first and second viewpoints are controlled in such a manner that the first and second movement paths diverge when a given circumstance occurs.

Abstract: This game system enables the entry of a new game terminal into a currently operating multiplayer game system, or the isolation of a specific game terminal from a currently operating multiplayer game system. Each game terminal includes a master/slave setting section which detects whether or not data is being transferred over data transfer lines when that game terminal starts up, and either sets itself to be the master machine if transfer data is not present, or sets itself to be a slave machine if transfer data is already present. The game system also includes an entry acceptance signal transfer section wherein the master machine transfers an entry acceptance signal between game terminals for accepting entries into the game system.
