PURPOSE:To correctly maintain its state, even in the case a smooth line is plotted by performing an antialiasing processing once, and thereafter, a different graphic is plotted behind its graphic, in a three-dimensional graphic. CONSTITUTION:The system is provided with a storage means 24 corresponding to a frame buffer having a display subjected to antialiasing processing, a storage means 23 corresponding to a Z buffer having Z value information for a three- dimensional processing, and also, a storage means 22 for storing a graphic image which is not subjected to antialiasing processing, by which in the case a different graphic is plotted behind a graphic subjected to antialiasing processing once, the antialiasing processing can be executed again with regard to its superposed part. |
