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.
