ABSTRACT:
A method of drawing figures for a multi-window system in which a plurality of window regions are set on a display screen, and in which a window which is partly overlapped on other windows and is partly concealed is controlled by being divided into a plurality of display or non-display subregions, and the displayed content is changed by designating the window. If a dot constituting the figure is generated from a dot generator, coordinate values of the dot are compared with position data of the designated window to select a dot located in the window. The selected dot is compared with position data of a subregion that constitutes the designated window to find a particular subregion in which the dot exists. If the particular subregion is a display region, the dot located therein is produced on the display screen. A dot generated next is compared with the particular subregion and is determined to be displayed or not. When the dot lies outside the particular subregion, the region to be compared to the dot position data is changed, and the dot position is compared with another subregion or with the designated window.
