Engineering
Professor Wins Academy Award
Technology has followed art in imitating life, and for his part in
marrying animation with human movement, Nels Madsen of Auburn Universitys
engineering faculty received an Academy Award for Technical Achievement
Feb. 12 in Pasadena, Calif.
Probably
best recognized for bringing to life the world of Gandalf and Frodo
in The Lord of the Rings trilogy and digitizing Tom
Hanks in The Polar Express, motion-capture technology
for computer character animation involves mapping human motion onto
the motion of a computer character. What these blockbuster films
have in common is their creation of animation under Giant Studios
direction using proprietary Motion Reality, Inc. (MRI) technology
that Madsen helped create.
Madsen
is an associate professor of mechanical engineering in Auburns
Samuel Ginn College of Engineering. He is recognized by the Board
of Governors of the Academy of Motion Picture Arts and Sciences
for his role in the software solution created by MRI and
licensed for entertainment to Giant Studios that applied
a unique biometric approach that has influenced the development
of motion-capture technology for motion pictures.
Madsen
shares the award with three former MRI colleagues Vaughn
Cato, Matthew Madden and Bill Lorton all now at Giant Studios.
Motion
capture is the recording of movement from simple change in
body position to complex contortions of the face and muscle masses
for real-time or delayed analysis. Markers placed on a subject
enable multiple video cameras to monitor movement. The video images
are digitized, the markers are recognized and a three-dimensional
computer model of the subject is derived.
What
I believe the Academy is recognizing us for, what we do so differently
than other groups in this area, and why the recognition is for software,
is the utilization of marker location, said Madsen, adding
that the traditional use of markers is to construct a stick image
of the subject by placing them on each joint.
The
problem with that is being required to have the markers in very
specific locations, he explained. You cant capture
subtle movement because you get a lot of incompatibilities. The
body is not connected together very well.
So
Atlanta-based MRI takes a systems approach that enables a more comprehensive
capture. More markers in more places on the body are viewed simultaneously
and understanding of body movement is used to deduce the most likely
associated human configuration. Madsen said this approach to the
body as a single integrated system as opposed to a collection of
unrelated elements enhances accuracy and real-time performance.
The software also allows captured human motion to be applied to
an animated character that is not human, making it especially appealing
in the entertainment field.
You
can use human motion to drive a model of something else, Madsen
said, opening the door to all kinds of things you dont
get with the marker-by-marker, point-by-point approach.
Madsen
said these software features led to Giant Studios selection
by director Peter Jackson to work on The Lord of the Rings
trilogy, which won an unprecedented three consecutive Academy Awards
for Visual Effects and whose third installment, The Lord of
the Rings: The Return of the King, earned the 2003 Academy
Award for Best Picture.
Giant
Studios, whose client list also includes Adidas, CNN and the Democratic
National Convention, was established in 1999 as the entertainment
licensee of MRI, formerly Biomechanics, Inc., founded in 1984 by
former Auburn faculty member Tom McLaughlin.
Our
technology represents more than 20 years of research in applying
sophisticated biomechanics and engineering methods to accurately
analyze 3-D motion, said McLaughlin, who in 1990 partnered
with Acclaim Entertainment to make the first use of 3-D human motion
in video games. That collaboration produced favorites like NFL Quarterback
Club, NBA Jam, Mortal Kombat, Turok, and Big Hurt Baseball featuring
Frank Thomas, an Auburn University baseball player from 1987-89
who began his all-star career with the Chicago White Sox as a first-round
draft pick and was American League Most Valuable Player in 1993
and 1994.
Also
in 1990 MRI developed the first real-time animation of human motion
and later that decade teamed with Acclaim and Warner Bros. to bring
cartoons to life in Batman Forever and Batman and Robin.
So
much of the credit for MRIs success goes to Nels, said
McLaughlin. The software hes written and advancements
hes made in motion-capture technology equivalent to
dozens of papers that he hasnt been able to write or have
published because of disclosure and patent issues are still
unrivaled anywhere else. Auburn University has an invaluable asset
in Nels Madsen.
Madsen
received his award in a ceremony at Pasadenas Ritz-Carlton
Huntington Hotel. He said it is an experience he will never forget.
It
was fun, Madsen said. About a week later I went to an
awards program for engineers in Montgomery. It's pretty clear that
movie stars know better how to party than engineers.
Actress
Scarlett Johansson, co-star of the 2003 blockbuster hit Lost
In Translation, hosted the event.
Some
of the guys had talked about trying to sneak kisses, but my wife
let me know well beforehand that I wouldn't be doing that,
Madsen said with a laugh. That was fine with me. I'm very
happy in my situation.
