Visit SIGGRAPH 99 Sketches & Applications and experience what it is like to spend 20 minutes inside the mind of some of the most creative thinkers in the field of computer graphics and interactive techniques, to capture the gem of an idea, and glimpse at the moment of inspiration.
 
Creative thinkers will share the "behind-the-scenes" problem solving inspirations that went into the making of ground breaking visual effects seen recently on theater screens. Some of the inspirations include the impressionist painted scenery through which Robin Williams and Cuba Gooding, Jr. walk in "What Dreams May Come," the brush strokes that come enchantingly alive in Disney's "Tarzan," convincingly engaging creature effects from "The Mummy" and Star Wars: Episode 1 "The Phantom Menace," clever enhancement techniques on traditional animation in "The Prince of Egypt," and the wet and messy mouse in the soon-to-be-released "Stuart Little." Attendees will learn the stories behind the computer graphics in entertainment.
 
Another session on commercial successes offers the opportunity to witness and take part in current paradigm shifts as animators and 3D characters create a storytelling experience from a 30-second advertising spot. New possibilities for consumer experiences will push the marketing envelope and spark the next bright idea in advertising as a digitally enhanced auto showroom is explored.
 
Next year's collaborators will engage in excited hallway brainstorming following presentations on simple yet powerfully novel uses of attraction and "noise" in imagery to enhance interaction and visual appeal. Issues of immersion, simple changes that make a world of difference to users' experience, and a HoloDeck also will be presented. Sketches embody the spectrum of new visual and interactive techniques combined with clever graphics gems to address a broad range of applications including medical visualization, artistic methods, collaborative technologies, film and television visual effects, and much more. This program is the SIGGRAPH 99 forum that best captures the energy of fast-paced change, exchange of ideas, the "Aha!" of inspired perception, and the late-breaking results of a dynamic community.
 
SIGGRAPH 99 offers 26 Sketches & Applications sessions with a total of 93 presentations in three key areas:
 
Animation

Richard Kidd, Sony Pictures Imageworks, is SIGGRAPH 99 Sketches & Applications Chair.
 
SIGGRAPH 99 Sketches & Applications Highlights
 
Animation
 
Cloth Animation for Star Wars: Episode 1 "The Phantom Menace"
Tim McLaughlin and John Anderson, Industrial Light & Magic
Two key challenges in designing the procedural animation software for the clothing are discussed. The development of appropriate representations for the physical properties of the large range of materials that were needed and the development of a set of controls to be used to define the performance aspects of the clothing are presented.
 
Digital Cars
Bob Hoffman, Digital Domain
The goal of the 1999 Pontiac Campaign was to create digital camera moves intended to “mime” the characteristics of practical photography. This commercial succeeded in pushing the animation to the next level -- tricking the viewer into believing that a practical vehicle had been shot and composited into a digital universe.
 
Technical Animation Issues for the Battle of the Droids of Star Wars: Episode 1 "The Phantom Menace"
James Tooley and Jim Horihan, Industrial Light & Magic
This presentation describes the issues critical to the successful use of motion-capture technology for Battle Droids that are very humanoid in nature and required a hyper-realistic range of motions. They also appear in large numbers that made the duplication of basic actions and motions a necessity for completing a shot.
 
Wet and Messy Fur
Armin Bruderlin, Sony Pictures Imageworks
In this presentation, two new effects implemented as part of a hybrid geometric/rendering hair/fur pipeline are covered, including the production of a wet fur look by clumping of individual hairs and the breaking up of combed hair along fur tracks on the skin.
 
Art, Design & Multimedia
 
The Application of Non-Periodic Tiling Patterns in the Creation of Artistic Images
Kenneth A. Huff
The physical world contains infinite examples of patterns of repetition. Computer-generated imagery often contains similar patterns, but frequently without the subtle imperfections found in nature. The use of a non-periodic tiling pattern allows for an appealing structure along with natural randomness.
 
Computational Expressionism: A Model for Drawing with Computation
Joanna Berzowska, Massachusetts Institute of Technology
The computational method suggests a new approach to the act of drawing. Instead of duplicating the methods and materials known from traditional media, a different perspective on visual thinking is sought that involves a more active participation in the higher-level design of drawing tools.
 
Nami
Kelly B. Heato, Robert V. Poor, and Andrew J. Wheeler, Massachusetts of Technology
Nami is a decentralized community of identical “orbs,” that provide a novel system for graphical animation of physical objects through a combination of distributed networking, touch interface, and mutable colors of light.
 
Nicholson NY/Pequot Interactives
Wells Packard, Nicholson NY
This sketch presents the design aspects of the site-specific, interactive installations commissioned to create the Mashantucket Pequot Museum. Touchscreens allow users to easily navigate an enormous amount of information in the form of 3D animations, documentary footage, traditional media, and even hand-painted cell animations, presented in broadcast-quality digital video.
 
Technical
 
Application of Computer Graphics for Design and Delivery of Conformal Radiation Therapy
Marc L. Kessler, Daniel L. McShan, and Benedick A. Fraass, The University of Michigan
Visualization techniques exploiting 3D computer graphics and medical image data are making it possible to safely escalate radiation doses in many tumor sites well beyond previously defined levels of “tolerance” and achieve improved local control and better cure rates.
 
Modeling HIV
Teresa Larsen and David Goodsell, The Scripps Research Institute
This sketch presents an accurate physical model of HIV at a scale of one million times actual size. The physical model can now be put into researcher's and student's hands so they can assemble and disassemble its various components and learn their structural interrelationships.
 
Virtual Car
Chrisoph Stratmann, ART + COM Medientechnologie und Gestaltung AG
The development of a sales support tool for DaimlerChrysler using VR technology is described. The Virtual Car system presents all possible variants of the vehicle and is intended for long-term use in the show room.
