Program, recording medium, three-dimensional grouped character controlling method and game apparatus

摘要

A program which can control a movement of grouped characters which move in a three-dimensional virtual space with a reality and great interest is provided. A three-dimensional polygon model is prepared, and each agent character is imparted an acceleration as kinematical performance where a force is obtained by multiplying a predetermined constant and a position vector together so as to follow each vertex of the polygon model (steps 208 and 210). Thereby, a group form of the agent characters having some fluctuation and a chaotic group form of the agent characters having some tendency are realized at the same time. A state that the group of the agent characters moves as if they were one creature as a whole is rendered by imparting a motion to the polygon model that the agent characters follow.
