Abstract
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 equal to or lower than a predetermined threshold value. The skeleton compressing part conducts first skeleton compression with respect to a skeleton having no 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 skeleton compression. A polygon file is generated based on compression skeleton data, model information of a polygon and a texture, and scenario information.
