Abstract: A computer graphics data display device and method simplify a movement interference calculation by use of an interference attribute of an object, and control a process time by predicting a display time of a frame. Furthermore, the number of simultaneously calculated moving objects is restricted to speed up the calculation, and a retrieving process can also be performed at a high speed using display data obtained by compressing editing data. If any change has arisen in the editing data, only change data are transmitted to a display data memory unit, and the editing data and the display data are concurrently processed. Thus, dynamic images can be successfully displayed with reality.

Abstract: A computer graphics image is moved on a display by executing an image data calculating process and an image data displaying process in parallel. A calculating section calculates moving image data and accumulates the result into a calculation result accumulating section. A display section forms and displays image data on the basis of the moving image data read out from the calculation result accumulating section. A control section controls the processes of the calculating section and display section to be executed in parallel. To provide parallel processing, the control section first sends an activation command to the calculating section, thereby allowing the calculation of the moving image data to be previously executed. After a predetermined amount of calculation result, for example, the calculation result of one frame is accumulated in the calculation result accumulating section, the control section sends an activation command to the display section thereby starting the display of the moving image.
