<p><P>PROBLEM TO BE SOLVED: To provide a program, an information storage medium, and an image generation system, enhancing specular and diffuse texture expressions. <P>SOLUTION: This image generation system includes a specular normal vector acquiring part for finding a specular normal vector whose direction is perturbed by a specular normal perturbation component, a diffuse normal vector acquiring part for finding a diffuse normal vector whose direction is perturbed by a diffuse normal perturbation component, and a writing processing part for applying lighting processing to an object based on an illumination model, by finding a specular color of the object, based on the specular normal vector, by finding a diffuse color of the object, based on the diffuse normal vector, and by finding a color of the object, based on the diffuse color and the specular color. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
