1. An image generation method for generating a two-dimensional image by texture mapping to three-dimensional polygons including textures that have been mapped to generate an overall pattern on a polygon, and modulation textures, comprising the steps of:
multiplying each texture that has been mapped by each modulation texture, wherein an amplitude of a modulation texture is changed as a distance from a vicinity of a viewpoint is changed; and
displaying on a display apparatus the generated two-dimensional image.
