Nora Willett will be presenting her general exam on Tuesday, May 10, 2016 at 10am in CS 402.

The members of her committee are Adam Finkelstein (adviser), Tom Funkhouser, and Szymon Rusinkiewicz.

Everyone is invited to attend her talk, and those faculty wishing to remain for the oral exam following are welcome to do so.  Her abstract and reading list follow below.

When bringing animated characters to life, artists often augment the
primary motion of a character by adding secondary animation such as
wrinkling cloth, jiggling bulges, or hair and leaves blown by wind.  Such
effects can often be achieved for 3D animation through physical
simulation.  However, 2D animations typically lack sufficient information
about the structure of the characters to support such simulations.
Animators therefore can only add secondary motion to animated illustrations
through arduous manual effort.  This paper presents a set of
physically-inspired building blocks that attach to layered, illustrated
characters in order to propagate motion in a way that produces
controllable, composable secondary animation.  These components can be
easily rigged and controlled via a small number of parameters that produce
an expressive range of effects.  Our approach supports a wide range of the
most common secondary effects, which we demonstrate with an assortment of
characters of varying complexity.
