PROBLEM TO BE SOLVED: To make respective texel coordinate values of a polygon surface individually adjustable. SOLUTION: This plotting processor is provided with an ordinary texture TX having respective texel values for expressing a texture color, and a table STX composed of a two-dimensional coordinate value st for shifting a texel coordinate value tex. In texture mapping, first of all, the two-dimensional coordinate value st is referred from the table STX by a reference address based on the texel coordinate value tex fomed from apex coordinates of a polygon PG, and next, the texel coordinate value tex is corrected by the two-dimensional coordinate value st, and a texel color tca of the ordinary texture TX is also referred by the texel coordinate value after correction, and is mapped on the polygon PG.
