(57)Abstract:
PROBLEM TO BE SOLVED: To provide bump mapping processing which brings about the feeling of materials of a mirror having irregularities on the surface and has a high effect though being simple.
SOLUTION: A gray pattern image Ib different in density by positions is synthesized with an original texture image Ia being a color image by a first synthesizing means 108 to obtain a first synthesized texture image Ie. Next, the original texture image Ia is enlarged on the basis of the direction or the like of a normal vector being an attribute OPA of a polygon Op to obtain an enlarged original texture image If. The enlarged original texture image If and a negative-positive inverted gray pattern image Id are synthesized by a second synthesizing means 112 to obtain a second synthesized texture image Ig. Finally, the second synthesized texture image Ig and the first synthesized texture image Ie are synthesized to produce a third synthesized texture image Ih. The feeling of materials of a mirror having the irregularities on the surface (metallic surface) is represented by the third synthesized texture image Ih.
