    In this paper, we present a method for editing a pre-existing motion such that it meets new needs yet preserves as much of the original quality as possible. Our approach enables the user to interactively position characters using direct manipulation. A spacetime constraints solver finds these positions while considering the entire motion. This paper discusses the three central challenges of creating such an approach: defining a constraint formulation that is rich enough to be effective, yet simple enough to afford fast solution; providing a solver that is fast enough to solve the constraint problems at interactive rates; and creating an interface that allows users to specify and visualize changes to entire motions. We present examples with a prototype system that permits interactive motion editing for articulated 3D characters on personal computers.
