THREE-DIMENSIONAL OBJECT DEFORMING METHOD FOR VIDEO GAME, VIDEO GAME DEVICE AND COMPUTER READABLE RECORDING MEDIUM WITH RECORDED PROGRAM FOR VIDEO GAME

摘要

PROBLEM TO BE SOLVED: To precisely deform a three-dimensional(3D) object in a virtual space by simple processing. SOLUTION: A non-processed cluster index and parallel moving amounts Tx, Ty and Tz are acquired (S33 and S35). In the case of the same frame, the order of clusters to be processed can be ignored. Next, concerning a non- processed apex corresponding to the acquired cluster index, an apex index and weight(w) of the relevant apex are acquired (S37-S43) On the basis of the parallel moving amounts and the weight(w) of the present frame, the coordinate value of an apex buffer is changed (S45). In this case, since the cluster is deformed by parallel moving, the order of clusters to be processed can be ignored and the apex coordinate after deformation can be calculated only by simple product and sum operation without performing matrix operation.
