Computer Animation Festival
The world's most accomplished digital artists presented 1997's best computer-generated animation in film and video at the SIGGRAPH 97 Computer Animation
Festival. There were daily showings in the Festival Screening Rooms at the Los
Angeles Convention Center, and four evening and two matinée showings of the
Electronic Theater at the historic Shrine Auditorium.
For SIGGRAPH 97, a record number of 538 submissions were considered by the jury,
and 55 were selected for the Electronic Theater. The entries were submitted from
a variety of sources:
Production and special effects companies
"The types of work submitted this year ranged from art/social comment and
visualizations to movie and feature film entries with high-end computer-generated characters," said Judith Crow, SIGGRAPH 97 Computer Animation Festival
chair. "The jury was particularly impressed to see technical developments from
recent SIGGRAPH conferences, such as techniques for rendering fur and skin, and
the use of scientific datasets, applied to the art and entertainment pieces."

Computer Animation Festival Highlights
Excerpts from "An American Werewolf in Paris"
John Grower and Diane Holland
Santa Barbara Studios, Inc.
Further pushing the photorealistic frontier, this feature film employs entirely
computer-generated werewolves. Digital fur, skin, and water shaken from the
animal's body combine with animated facial expressions and body motion to create
this mythical creature.
The Animation of M.C. Escher's "Belvedere"
Escher's lithograph of an impossible building led to an intriguing challenge
for this animator: how to look at this kind of impossible object in different
orientations. An illusory rotation and drawing method was developed for this
most unusual example of 3D reconstruction from 2D imagery.
A Cloud is Born
David S. Ebert
University of Maryland Baltimore County
John R. Anderson
Both these brief pieces use advanced rendering techniques for an enhanced
representation of natural phenomena. "A Cloud is Born" features the formation
and fly-through of a volumetric cloud created by combining implicit functions
and procedural turbulence-based volume density functions. The cloud geometry and
animation are procedurally controlled, and the illumination and shadowing are
physically-based. "Digital Smoke" is based on a direct physical simulation and
uses a hybrid volume rendering/radiosity approach.
Digital Truth in Tian An Men
By using live action footage from the demonstration
in Tian An Men Square and reconstructing the
scene as 3D graphics the animators "changed history ... to tell the digital
FACADE: Modeling and Rendering Architecture from Photographs
Paul E. Debevec
University of California, Berkeley
Continuing the theme of 3D reconstruction, a group of students have further
developed their SIGGRAPH 96 paper of the same name into a combined technical and
creative piece for the Electronic Theater. Matching a virtual flight path to
recovered camera motion, the team demonstrates a photorealistic reconstruction
of a large portion of the Berkeley campus.
"Fifth Element:" Leeloo's Reconstruction & Time Square Montage
Two years ago, Alexander Tsiara's Body Voyage Project was a visualization
highlight of the Electronic Theater. The same human body dataset is employed
here in the fantastical reconstruction scene from this recently released feature
Interactive Learning and Teaching Environment
Stefan Lehmann and Thomas Overberg
University of Wuppertal
This undergraduate degree project explores the use of computer graphics and
remote sensing for educational purposes. The animation focuses on an emergency
situation requiring repair of a pipeline disrupted by an earthquake. It
explores methods for fast identification of knowledge resources and
deployment of sophisticated simulation processes in order to solve the problem
of mending the damaged pipe.
Las Campanas Redshift Survey in 3D
University of WuppertalHome Run Pictures
This animation was created as part of the upcoming PBS series on mathematics:
"Life by the Numbers." Declination and right ascension coordinates, a redshift
value, and descriptive variables for approximately
26,000 galaxies were assembled and input. The resultant animation clearly shows
the clump-like texture of intergalactic space.
Simulation of 1994 Northridge Earthquake Aftershock
Pittsburgh Supercomputing Center
This educational video illustrates earthquake research at Carnegie Mellon
University through data visualization. Computer simulation data demonstrate how
an alluvial basin's structure and composition modify the horizontal
displacement effects caused by a Northridge earthquake aftershock.
School of Visual Arts
Raquel Coelho is using computer graphics animation as an extension to her work
as a children's book illustrator in this stylized depiction of an Amazonian
tribal story. Both visuals and sound track are richly layered. The visual
concept has nine scenes layered in 3D space, and the camera travels from scene 1
to scene 9, revealing the story as their nine layers come to life.
