Abstract

A first texture including first color information, a second texture including second color information, and a third texture including height information are managed. The first color information, of the first texture corresponding to a surface of an object, obtained on the basis of a first correspondence relationship is obtained. A second correspondence relationship which is a relationship between the surface of the object and the second texture is corrected on the basis of a relationship between a line-of-sight direction of a virtual camera and orientation of the surface of the object and the height information specified on the basis of a third correspondence relationship, and the second color information is obtained from the second texture on the basis of the corrected second correspondence relationship. Then, a rendering color is determined using the obtained color information, and the surface of the object is rendered.
