Broad Area Colloquium For AI-Geometry-Graphics-Robotics-Vision
Physical Simulation in Visual Effects

The art of visual effects can be neatly divided into two
camps: character animation and everything else. Good character
animators have unique abilities to coax the illusion of life
out of an object. That is not what this talk is about! We're
going to examine the everything else: The art of simulating
physical things in movies. This started with simple particle
systems moving small masses using f = m a, but has now grown
to encompass all natural (and unnatural) phenomena.
The process usually starts simply with a line in a screenplay
like, "The dam starts to collapse." This is then drawn as a picture
by a storyboard artist collaborating with the director.
After that, a visual effects company gets it with the command,
"Make it look cool. And real." Then the fun begins.
Using fluid dynamics as an example, we will go through the process
and technology of physical simulation in a visual effects company,
how artists work and how the software is developed. We will
concentrate on the current state of the art and what challenges
lie ahead for us.
About the Speaker
Dr. Doug Roble is the Creative Director of the Software Department at
Digital Domain, the multiple Academy Award-winning visual effects
studio located in Venice, CA. He has been writing software and doing
research since he joined the company in 1993. In 1999, Doug won a
Scientific and Technical Achievement Academy Award for his 3D
tracking/scene reconstruction program, "track".
Doug's interests cover widely different areas of computer graphics.
He has written many different software tools including a fluid
dynamics package, a motion capture editing and manipulation tool, a
complete computer vision toolkit and many others.
Before Digital Domain, Doug received his Ph.D. in Computer Science
from The Ohio State University in 1993. He received his Master's
from Ohio State and his Bachelor's degree in Electrical Engineering
from the University of Colorado.
