Abstract: The present disclosure relates to a motion retargeting method and apparatus for character animation, and the method may include generating an intermediate object including at least one of a skeleton and a mesh based on a source motion and a target character, extracting keyframes of the intermediate object, constituting target rig parameters based on the extracted keyframes, and performing spacetime optimization on the target rig parameters to minimize a pose error between the intermediate object and the target character.
