Abstract:
1. An action modeling device that models an action of a character having an extremity that is connected to a trunk via a first joint and has a second joint in the middle, the extremity being rotatable around the first joint as a center within predetermined motion ranges, the action modeling device comprising: a storage that stores a range of length of the extremity; the storage that further stores angle range data for a plurality of extremity lengths within the range of length of the extremity, the angle range data defining different angle range sets at which the second joint is rotatable for each of the plurality of extremity lengths, each angle range set including positions of a particular portion of the extremity relative to the first joint in association with angle ranges, the particular portion being located farther from the first joint than the second joint on the extremity; a processor; and a memory storing instructions that, when executed by the processor, cause the processor to perform operations including: determining a position of the particular portion of the extremity having the length changed by the processor using the first joint as a reference position; and determining a position of the second joint, based on one of the angle range sets corresponding to the length of the extremity changed by the processor stored in the storage in accordance with the position of the particular portion determined by the processor and a corresponding one of the angle ranges.
