Continuous and synchronized whole-body motions are essential for achieving believable autonomous virtual humans in interactive applications. We present a new motion control architecture based on generic controllers that can be hierarchically interconnected and reused in real-time. The hierarchical organization implies that leaf controllers are motion generators while the other nodes are connectors, performing operations such as interpolation, blending, and precise scheduling of children
