Motion modeling method and device using virtual joint sphere

초록

Disclosed herein is a motion modeling method and device using a virtual joint sphere. The motion modeling method using the virtual joint sphere includes (a) modeling a 3D virtual character, wherein the 3D virtual character sets a virtual joint sphere for each body part; and (b) forming a trajectory for a motion of a target body part of the 3D virtual character as a specific motion is performed on a surface of the virtual joint sphere assigned to the target body part, when reconstructing the motion of the 3D virtual character according to the specific motion.
