Apparatus and method for drawing figures
摘要:
An apparatus and a method for drawing figures. The apparatus includes a memory apparatus for storing part figures having drawing order judging rules whereby a target figure is drawn, a selecting apparatus for selecting part figures from the memory apparatus according to the user's instructions, and an apparatus for determining the drawing order based on the drawing order rules of a plurality of part figures that were selected from the memory apparatus. The part figures including a given figure are stored in the memory apparatus along with their respective drawing order rules. A second apparatus is provided whereby these part figures are searched for and transferred into a temporary memory area in accordance with the user's instructions. A drawing order determining apparatus determines drawing orders based on the drawing order rules of the user-selected part figures transferred into the temporary memory area. The part figures are drawn on a display unit in accordance with the drawing orders thus determined.
