Abstract
An image processing program creates a gradation of a sharp edge shadow and a gradation of subtle colors. The program causes a computer to perform a step in which a diffuse reflection from a first and second object and a shadow of the first object on the second object in a lighting information texture which are generated by a virtual light hitting the first and second object are superimposed onto a base texture which represents details of the object so that a target object is mapped; a step in which a mirror reflection which is generated by the virtual light hitting the first and second object is calculated so that a specular reflection is generated to surfaces of the first and second object; and a step in which the specular reflection is masked based on mask information provided in the lighting information texture which is mapped to the second object.
