<p>PROBLEM TO BE SOLVED: To provide an image generation system capable of realizing realistic environment mapping with a small processing burden and information storage medium. SOLUTION: This system maps an environment texture onto an object (automobile) while shifting or turning an original image area on the basis of course information (course distance, course width and course direction). Deformation processing such as polar coordinate transform is applied to an environment texture of a short-distance view to be composited with an environment texture of a long-distance view. An image obtained by mapping the environment texture onto a virtual object is plotted in a texture space, and the plotted deformed environment texture that has undergone deformation processing is mapped onto the object. A 1st environment texture is subjected to a fade-out processing and a 2nd environment texture is subjected to fade-in processing when the 1st environment texture is switched to the 2nd environment texture. A map object for environment texture switching is arranged at a connection area for switching the environment textures. The environment textures are switched over on the basis of the course information.</p> |
