A patterned polygon rendering apparatus has an edge dot attribute setting section 1 that assigns an attribute dot, which indicates an edge of a polygon, to respective dots located in an edge line of the polygon and stores the assigned attribute dots in work memory 2 on a per-dot basis, to thus perform edge processing; an internal attribute dot setting section 3 that assigns an attribute dot, which indicates the inside of the polygon, to respective dots located in an internal region of the polygon by reference to the work memory 2 and stores the assigned attribute dots into the work memory 2, to thus perform painting processing; and a pattern setting section 4 that sets edge color data to the dots assigned the attribute dots, which indicate the edges of the polygon, by reference to the work memory 2, sets pattern data to the dots assigned the attribute dots indicating the inside of the polygon, and renders the data stored in the work memory 2 to the frame memory 6, to thus perform pattern setting processing.
