“…In [26] the estimation of a character's motion is cast as an optimization problem in a low-dimensional subspace, but one limitation of the method is that for defining this subspace a suitable set of motions must be selected by the user. Fang and Pollard [9] also use optimization as a way to generate new animations and, for this purpose, they consider certain physics constraints which are shown to lead to fast optimization algorithms. In [33], Yamane et al make use of a motion capture database to synthesize animations of a human manipulating an object and they also provide a planning algorithm for generating the object's collision-free path.…”

“…The first one consists in optimizing the joint angles and torques until a correct motion is obtained [12], [13]. Some authors have proposed to control simpler dynamic constraints (such as the linear and angular momentum [14] or the aggregate-force constraints [15]) instead of joint torques leading to lower computation time. However, these methods are clearly designed for off-line simulation.…”
