PURPOSE:To increase the circle drawing speed. CONSTITUTION:This circle drawing method in an information processing system having no graphic drawing controllers consists of an angle discrimination processing 1 which discriminates the angle of a circle to be drawn, a coordinate calculation processing 2 which calculates coordinates of the circle based on the angle obtained by the angle discrimination processing, and a circle drawing processing 3 which draws coordinates calculated by the coordinate calculation processing. |
