It is an objective to provide a image generating system and program capable of performing an environment mapping which can accurately represent the reflection of light source and the like. An environment texture to be viewed in an upward direction from an object is mapped onto the object in a direction toward the object from above the object without depending on the position or rotational angle of a virtual camera. A rotation matrix obtained from the rotational angle of the object about an axis in the world coordinate system is used to rotate the normal vector of the object. The coordinates NXW and NZW of the rotated normal vector are then used to obtain coordinates U and V. Another rotation matrix for transforming the local coordinate system to a coordinate system (XW, ZW, YW) may be used. With a surface of the object of which normal vector is oriented downwardly and slantingly with respect to the horizontal direction, an environment texture to be mapped when the normal vector is oriented to the horizontal direction is mapped, or the environment mapping may be omitted. The environment texture may be one that increases its brightness when the normal vector of the object is oriented toward a light source or shading processing.
