POLYGON DRAWING METHOD AND DEVICE

摘要

PURPOSE: A polygon drawing method and a device are provided to obtain clear drawings without greatly increasing processing load and perform various displays without using a memory of great capacitance. CONSTITUTION: A polygon drawing method comprises steps of: performing an exclusive OR process per unit amount forming outer edge information representing the outline of the polygon; generating mask information ordering coloring interior of the outline; and drawing the polygon using the generated mask information. The polygon drawing device comprises an outline coordinate information memory(101), an outline information generator(102), a control plain(103), a mask information generator(104), a sequencer(105), a definite straight line generator(106) and a drawing plain(107).
