COMPRESSION METHOD FOR ANIMATION INFORMATION AND COMPUTER READABLE RECORDING MEDIUM RECORDING COMPRESSION PROGRAM OF ANIMATION INFORMATION

摘要

PROBLEM TO BE SOLVED: To effectively compress the animation information of a key frame animation. SOLUTION: When the animation information of a key frame system is compressed, the reference key frame information is read, recorded or transmitted (S6 and S12). Then the next key frame information is read in response to the end of output of the immediately preceding key frame information (S14). The object information included in the read key frame information is compared with the corresponding object information included in the immediately preceding key frame information, and the compressed key frame information including the object information that includes only the state information different from the link information is recorded or transmitted (S9 or S11). Then the 2nd output step (S9 or S11) is repeated until the compression of all information to be compressed is over (S2 to S14).
