Parametric Motion Graphs
Proceedings of the Symposium on Computer Animation: Short Papers — sep 2006
We present a motion synthesis technique that allows automated authoring of high-fidelity, controllable motion
streams for interactive applications, such as video games and simulations. Our technique uses a new data structure
called a parametric motion graph (PMGs) that describes valid ways of producing streams of motion by concatenating
motion clips dynamically generated through parametric synthesis. PMGs can provide accurate control
of individual motion clips while generating seamless linear blend transitions between them in realtime. The key to
our technique is using sampling methods to identify and represent good transitions between parameterized spaces
of motion. Because PMGs contain a single, controllable node for each type of motion, they are highly structured,
facilitating fast decision-making for interactive character control. We have created characters that seamlessly
perform requested actions in realtime using different kinds of motion, such as cartwheeling and boxing.
