<p>PROBLEM TO BE SOLVED: To provide a method for forming an animation picture in real time in a picture processor such as a game machine which plots a model with plural polygons by general computer graphic processing. SOLUTION: Plural polygons are acquired which have normal data in apex data and constitute the model, and the model comprising plural polygons is divided into polygons of a first color part and those of a second color part by boundaries in accordance with the direction of a light source and the normal of the model, and a first monochromatic texture is stuck to divided polygons of the first color part, and a second monochromatic texture is stuck to divided polygons of the second color part, and polygons crossing the boundaries are divided along the boundaries, and the first monochromatic texture is stuck to polygons belonging to the first color part out of divided polygons, and the second monochromatic texture is stuck to polygons belonging to the second color part.</p> |
