SIGGRAPH 2004 Sketches Program Shows Record Growth

(Chicago, IL - June 18, 2004) - ACM SIGGRAPH announced the content of the Sketches program for SIGGRAPH 2004, the 31st International Conference on Computer Graphics and Interactive Techniques, being held 8 -12 August, at the Los Angeles Convention Center. A record 423 submissions were submitted to Sketches and 153 were chosen for presentation at the conference.

The SIGGRAPH 2004 Sketches program is a premier forum for presenting the latest new ideas, methods, interdisciplinary applications, and uses of computer graphics and interactive techniques. Presentations cover a broad spectrum of topics in art, design, science, engineering, academic research, industrial development, practical tools, and behind-the-scenes explanations of commercial and artistic works.

"The record number of submissions is due in large part to an increase in submissions from animation and special-effects studios -- reflecting the role of the Sketches program as the primary venue for presentations in the industry," said Ronen Barzel, SIGGRAPH 2004 Sketches Chair. "The jury selected submissions that not only have spectacular results, but also showcase new techniques and insights for achieving those results."

Highlights from the SIGGRAPH 2004 Sketches Program:

The Art of SSX3
Henry LaBounta, Electronic Arts Canada
A behind-the-scenes look at the visual development of the SSX3 videogame. The creative process used to develop the visuals that support and enhance gameplay will also be discussed.

Artifacts of the Presence Era: Visualizing Presence for Posterity
Judith Donath, Ethan Howe, Ethan Perry, and Fernanda B. Viégas, Massachusetts Institute of Technology Media Lab
This powerful art installation uses a geological metaphor to create an impressionistic visualization of the evolving history in a museum gallery.

Controsenso But Not So Much: Digital Artifacts to Ease Communication and Exchange With Seeing-Impaired People
Maria Alberta Alberti, Università degli Studi di Milano
Andrea Brogi, Luca Dusio, and Manuela Garcia, Politecnico di Milano
Stephan Knobloch, Köln International School of Design
Paola Trapani, Università degli Studi di Milano

A truly unique perspective on Genoa, Italy as it has never been seen before. A tour guided by seeing-impaired people to reveal city life in poetry. Engaging and interactive storytelling enhanced by sound and images.

Experimental Validation of Analytical BRDF Models
Addy Ngan, Frédo Durand, and Wojciech Matusik, Massachusetts Institute of Technology
A guide to the performance of several popular BRDF models based on experimental validations employing a large dataset of real BRDFs measured with high precision.

Making of the Superpunch
George Borshukov, Ken Faiman, John Jack, Oystein Larsen, Tadao Mihashi, Kody Sabourin, and Masuo Suzuki, ESC Entertainment
Oliver James and Scot Schinderman, formerly ESC Entertainment

The Superpunch was considered the most difficult shot in all "The Matrix" sequels, most notably due to the challenge of showing a full-frame computer-generated face of a well-known human actor.

Modeling Expressive 3D Caricatures
Ergun Akleman and Jon Reisch, Texas A&M University
An educational method to teach students artistic concepts of abstraction and exaggeration by modeling expressive 3D caricatures. All students, regardless of artistic abilities or experience, are able to create convincing caricatures.

Photometric Stereo for Archeological Inscriptions
Per Einarsson, Linköpings universitet
Paul Debevec and Tim Hawkins, USC Institute for Creative Technologies

A low-cost system suitable for use in the field for acquiring high-resolution geometry and reflectance properties using photometric stereo.

Unlighting the Parthenon
Christopher Tchou, Paul Debevec, Per Einarsson, Marcos Fajardo, and Jessi Stumpfel, USC Institute for Creative Technologies
A method for calculating the reflectance of a complex diffuse object's surface in arbitrary natural lighting. Computer animation techniques are used to transport viewers back to Athens and the building's original sculptures, which are presently scattered in museums around the world. This impressive animation was also selected for the SIGGRAPH 2004 Computer Animation Festival.

The SIGGRAPH 2004 Sketches program is Sunday, 8 August through Thursday, 12 August.
