Abstract:
Traditional hand animation is in many cases superior to simulated
motion for conveying information about character and events.
Much of this superiority comes from an animator's ability to abstract
motion and play to human perceptual effects. However, experienced
animators are difficult to come by and the resulting motion
is typically not interactive. On the other hand, procedural models
for generating motion, such as physical simulation, can create motion
on the fly but are poor at stylizing movement. We start to bridge
this gap with a technique that creates cartoon style deformations automatically
while preserving desirable qualities of the object's appearance
and motion. Our method is focused on squash-and-stretch
deformations based on the velocity and collision parameters of the
object, making it suitable for procedural animation systems. The
user has direct control of the object's motion through a set of simple
parameters that drive specific features of the motion, such as
the degree of squash and stretch. We demonstrate our approach
with examples from our prototype system.
