Computer graphics data display device and method based on a high-speed generation of a changed image
First Claim
1. A computer graphics data display device for displaying an object in a computer graphics world comprising:
- attribute defining/setting means for defining and setting an attribute indicating a type of calculation to determine a state change for at least one object in the computer graphics world;
attribute memory means for storing the attribute of the at least one object set by said attribute defining/setting means;
state change calculating means for calculating the state change of a displayed object according to the attribute of at least one related object in response to one of a movement of the displayed object in the computer graphics world and receipt of an external activation instruction, the at least one related object including one of the displayed object and an other object; and
result display means for displaying a result of a calculation.

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.
