Abstract
A three-dimensional model is created without carrying out complicated modeling by incorporating elements of a two-dimensional image into the three-dimensional model. A two-dimensional image inputted to a two-dimensional image input section is stored in a two-dimensional image storing section, while information on a predetermined element of the two-dimensional image is extracted in a processing section in relation to three-dimensional information, and thereafter transformed to three-dimensional information. A three-dimensional modeling data producing section adds the three-dimensional information transformed from the element information to modeling data which expresses a three-dimensional shape which is previously prepared, and thereby creates a three-dimensional model. A rendering section subjects the three-dimensional model thus created to bump mapping, texture mapping or the like, and thereafter, a three-dimensional image is displayed by a display section.
