Abstract: A method of generating a ball model of an object for generating realistic poses includes receiving a wire mesh model of the object, which has a skeletal structure, generating a first ball model from the wire mesh model, generating a second ball model from the first ball model by determining, for each ball of the first ball model, a number of nearest points of the wire mesh model, and, for each of one or more joints of the skeletal structure, calculating a weight for the balls by averaging the weights of the points nearest to the joint, and assigning the calculated weight to the ball.
