A drawing processing apparatus is disclosed. A graphic index of a graphic included in a display screen or graphic description information which includes a setting parameter to be applied to the graphic is determined for each of regions dividing the display screen. A data size of the graphic description information is aggregated for the regions. A start address in a memory is determined to store the graphic description information into a successive storage area in the memory, based on the aggregated data size. The data size of an area of an overflow occurrence target is stored when the overflow occurs. The graphic description information of the regions is successively written from the start address when the overflow does not occur. A write process is stopped, and resumed from the area of the overflow occurrence target by using the data size when the overflow occurs.

A drawing apparatus has dividing unit for dividing a rectangle frame circumscribing a triangle displayed on a display screen into a plurality of rectangle segments. A determining unit sequentially determines whether each rectangle segment included in the rectangle frame overlaps the triangle in a predetermined direction and outputs a determination result of overlap or nonoverlap. The sequential determination of overlap or nonoverlap is stopped in the predetermined direction, if a determination result output from the determining unit changes from the overlap to the nonoverlap. A drawing process is performed on the rectangle segment determined to overlap the triangle.
