We propose a method to animate a 3D virtual human generating keyframes of the model and interpolating to achieve a realistic animation. The first two steps refer to the human modeling, the rigging and the skinning. The third step deals with the human in a programming environment to obtain the animation by quadratic interpolation and consists of the parallel version to display the human movements. The method has shown to produce real animations of an articulated object in an easy and fast manner, optimizing the memory usage of the GPU parallel implementation.
