Abstract

A game system in which a game field is configured in a virtual three-dimensional space and a display image of said game field visible from a predetermined viewpoint is formed to thereby be displayed as a game picture. The system comprises a texture storing device for storing in advance a texture representing a three-dimensional configuration as a two-dimensional pattern, a mapping surface setting device for setting a mapping surface of the texture in the game field, a texture processing device for processing the texture readout from the texture storing device in accordance with a dispositional relationship between the viewpoint and the mapping surface, and a texture mapping device for mapping the processed texture on the mapping surface.
