Motion Editing: Principles, Practice, and Promise Motion editing techniques allow existing motions to be changed to meet new needs. Using these techniques, animators can fix imperfect motions, reuse motions from a library in multiple settings, and dynamically generate motions for interactive environments. This course began its survey of recent technologies for motion editing by analyzing actual motion editing problems, then reviewed the mathematical foundations for animation as a common vocabulary for discussing editing techniques. Some recent motion editing technologies, such as signal processing and space-time constraints, were introduced in a manner that presented their theory, implementation, and practical application. The course also reviewed the relationship among various motion editing tools and how they can be integrated.   Organizer Michael Gleicher University of Wisconsin, Madison   Lecturers Barton Gawboy Mark Schafe Anohana Production Management   Michael Gleicher University of Wisconsin, Madison   Zoran Popovic Carnegie Mellon University   Jeffrey Thingvold LambSoft, Inc.
