摘要

Hair is connected to a head portion of a character that is formed by multiple polygons. The positions of the respective bones provided to portions other than the half are calculated based on an operation of the character. A reference axis is fixed based on the positions of the bones of the portions other than the hair. A position of a bone arranged in the hair is calculated based on an external force. When an angle, which the bone of the hair forms with the reference axis, is not in the range of a predetermined reference angle, the position of the bone of the hair is corrected to be in the range of the reference angle. The positions of the polygons, which form the character, are determined based on only the positions of the bones provided to the character.
