TITLE:
Toward Greater Artistic Control for Interactive Evolution
of Images and Animation
by David Hart, Disney Interactive Studios
ABSTRACT:
We present several practical improvements to the interactive
evolution of 2D images, some of which are also applicable to more
general genetic programming problems. Two new expressive mutation
types are given, and genotype transforms are introduced as a way to
make genotypes more receptive to mutation. For evolving animation, we
introduce tree alignments in order to eliminate previous limitations
using the genetic cross dissolve. We create an algorithm for
constructing the dissolve expression using an alignment, and present
several alignment methods, each with different advantages. The goal
of these improvements is to strengthen the interactive evolution
toolset and give the artist greater control and expressive power.
BIO:
David A. Hart earned his B.S. in computer science with honors from the
University of Utah in 1997, and M.S. in computer graphics with honors
from Cornell University in 1999. After completing the M.S., he
returned to the University of Utah to work with the Scientific
Computing and Imaging group for a year researching remote
visualization techniques. In 2000, he joined the effects department
at PDI/DreamWorks where he developed and animated effects for a half
dozen feature films including the "Shrek" series, and led new shader
development for "Madagascar". David again returned to Utah in 2005,
