Controlling the movement of an articulated figure using parametric frame-space interpolation

This paper describes parametric frame space interpolation, a new technique for motion control which allows an animator to define a range of movements using a set of reference movements (a frame space). Once this frame space has been constructed, an animator can specify an envisioned movement in terms of these reference movements or, more precisely, as an interpolation between these reference movements. The result is a high-level motion control mechanism which, while powerful, retains the artistic expressiveness and visual emphasis characteristic of parametric keyframing. Then we will develop simple human locomotion model that illustrates the use of this parametric frame space interpolation technique. This locomotion model blends a range of walking and running movements to form a unified motion framework.
