Title: Interactive Optimal Control for Passive Systems Using Model Reduction

In this talk, I will present my recent work on designing fast optimal

controllers for (fully-actuated) passive systems (3D deformable

objects, fluids). Such controllers make it possible for the animator

to edit physically based animations at (near-)interactive rates. I

will discuss how speed can be achieved by projecting the physical

system to a properly selected low-dimensional space, where the optimal

control problem can be (approximately) solved more quickly. I will

show how to accelerate, by orders of magnitude, two standard types of

control algorithms: a Linear-Quadratic Regulator for editing

pre-existing animations, and the Adjoint Method (space-time

optimization) for the creation of new animations from sparse artist

input (e.g., keyframes).
