✦ Synopsis

Tools for assisting with editing human motion have become one of the most active research areas in the field of computer animation. Not surprisingly, the area has demonstrated some stunning successes in both research and practice. This paper explores the range of constraint-based techniques used to alter motions while preserving specific spatial features. We examine a variety of methods, defining a taxonomy of these methods that is categorized by the mechanism employed to enforce temporal constraints. We pay particular attention to a less explored category of techniques that we term per-frame inverse kinematics plus filtering, and we show how these methods may provide an easier to implement while retaining the benefits of other approaches.
