Image generation system, program, and information storage medium
First Claim
1. An image generation method comprising:
- assigning, to a given object or a given topographic surface disposed in a virtual three-dimensional space, a virtual object which has at least one of nonuniform brightness or nonuniform color and is used for representing a light reflection effect on the object or the topographic surface, and storing the virtual object in a storage section;
determining a position of the virtual object so that the virtual object moves to follow a virtual camera or a player'"'"'s character, and disposing the virtual object at the determined position; and
generating an image of the virtual three-dimensional space viewed from the virtual camera by performing translucent blending processing of the object or the topographic surface and the virtual object assigned to the object or the topographic surface.

Abstract
An image generation system, program, and information storage medium can realistically represent reflection of light on a given object or topographic surface with a reduced computation load. The image generation system includes a section which assigns, to a given object or topographic surface disposed in a virtual three-dimensional space, a virtual object which has at least one of nonuniform brightness or color and is used for representing a light reflection effect on the object or topographic surface; a section which determines a position of the virtual object so that the virtual object moves to follow a virtual camera or player'"'"'s character, and disposes the virtual object at the determined position; and a section which generates an image of the virtual three-dimensional space viewed from the virtual camera by performing translucent blending processing of the object or topographic surface and the virtual object assigned to the object or topographic surface.
