Abstract: In this paper we provide methods that allow for path-based editing of existing motion data. We begin by exploring the concept of path as an abstraction of motion, and show how many of the common motion editing tools fail to provide proper control over this useful property. We provide a simple extension to displacement mapping methods that provide better control over the path in a manner that is easy to implement in current systems. We then extend this simple method to avoid violation of geometric constraints such as foot-skate.
