Abstract:
A transmitter of three-dimensional skeleton structure motions in which motion data of a skeleton structure in three-dimensional computer graphics (CG) is transmitted from a transmitting end to a receiving end and, based on the transmitted skeleton structure motion data, to create animation at the receiving end, the transmitter comprising:(1) means for disassembling the motion data of the skeleton structure into element data characterizing the motions in three-dimensional virtual space and transmitting the element data as time series data in which the disassembled element data is accompanied by connection methods thereto, and for transmitting an initial information as CG animation data, the initial information including hierarchy data for defining a hierarchical relationship of the skeleton structure, an initial state of the hierarchy data, constraint of the joints of skeletons, shape data to be attached to the skeletons, and data relative to the attachment to the skeleton structure; and(2) transferring means for transferring the CG animation data from a transmitting end computer to a receiving end computer.
