The present invention relates to a three-dimensional skeleton data compression apparatus for compressing a skeleton data amount without degrading rendering quality of a three-dimensional object. A weight detecting part detects weight information that is a numerical value obtained from input skeleton data, showing a degree of the influence of the movement of a skeleton on a vertex, and a weight compressing part deletes a value equ al to or lower than a predetermined threshold value. The skeleton compressing part conducts first skeleton compression with respect to a skeleton having n o polygon vertex in which an effective weight value is set. The skeleton compressing part also detects relative movement between skeletons, and second skeleton compression is performed to reduce/integrate a skeleton group integrated without relative movement into a unified skeleton. If required, masks are put on skeletons that are not to be subjected to skeleto n compression. A polygon file is generated based on compression skeleton data, model information of a polygon and a texture, and scenario information.</SDO AB> |
