Character‘s animation is the most complicated, but at the same time the most important field of the computer animation. The main problem is related with realistic, flexible representation of human motion, when complex and large computations occur. Hybrid, human motion analyzing algorithm has been introduced theoretically. This algorithm is based on input of constraints, and one of the main constrains is mass distribution of human parts. Transitional motion representations are build, and their adjustment are computed while using aproxsimation of multiresolution B-splines. Advantage of this algorithm is that for calculation universal spline handling metric can be used, but disadvantage – there is no optimal algorithm.
