Papers Fact Sheet


Thirteen paper sessions and 52 papers were presented at SIGGRAPH 96. SIGGRAPH Papers are an annual forum for intellectual achievement and advancements in computer graphics technology. Following each Paper presentation, attendees and presenters were invited to meet in the Papers breakout room for continued discussion.

"SIGGRAPH 96 Papers are selected for the novelty and importance of the research, system, or applications they describe. The ideas from the research Papers will soon find their way into new products and new development trends," said Holly Rushmeier, SIGGRAPH 96 Papers Chair.

Image-based Modeling and Rendering

Papers in this category showed how researchers are developing new data structures for representing scenes that enable user walk-through without accessing the original scene geometry. The new data structures also allow the use of captured imagery beyond simply mapping the images onto the surfaces.

Light Field Rendering
Marc Levoy
Pat Hanrahan
Stanford University

The Lumigraph
Steven Fortler
Radek Grzeszczuk
Richard Szeliski
Michael Cohen
Microsoft Research

Light Field Rendering and The Lumigraph describe new structures for representing scenes. The techniques outlined offer the possibility of viewing very complex objects and scenes without being bounded by the limited number of polygons per second a device can display.

Storytelling

Computer graphics is not just about the mechanics of displaying objects on the screen, but about displaying images that convey meaning effectively. The Papers in the storytelling sessions described high-level methods to specify and evaluate imagery.

Disney's Aladdin: First Steps Toward Storytelling in Virtual Reality
Randy Pausch
University of Virginia

Jon Snoddy
Robert Taylor
Scott Watson
Eric Halestine
Walt Disney Imagineering

Disney's Aladdin: First Steps Toward Storytelling in Virtual Reality is a landmark study of the effectiveness of virtual reality to tell a story by analyzing the response of over 45,000 people who experienced a high-fidelity virtual reality system.

Comic Chat
David Kurlander
Tim Skelly
Microsoft Research

David Salesin
University of Washington

Comic Chat presented a method to construct deceptively simple-looking graphics -- graphics similar to those in newspaper comic strips -- that allow groups of people to communicate on an online service.

Illustration

At one time, all computer graphics imagery looked like it was generated on a computer. As technology advanced, imagery became more realistic looking, like simulated photography. Illustration Papers described efforts to develop powerful tools to simulate expression in other traditional media, such as pen and ink and oil or water paint.

Rendering Freeform Surfaces in Pen and Ink
Georges Winkenback
David Salesin
University of Washington

Rendering Freeform Surfaces in Pen and Ink described a method for automatic generation of pen-and-ink-style drawings of complicated smooth surfaces.

Painterly Rendering for Animation
Barbara Meier
Walt Disney Feature Animation

Painterly Rendering for Animation presented an elegant technique for generating animation that looks like it was produced entirely by traditional methods of painting.

Virtual Reality

Virtual reality systems use a number of perceptual cues, such as stereo displays and haptic feedback, to give the user the illusion of being in an environment that exists only on the computer. Two SIGGRAPH 96 Papers addressed the performance issues that have prevented virtual reality systems from being used in practical applications.

Adding Force Feedback to Graphics Systems: Issues and Solutions
William Mark
Scott Randolph
Mark Finch
James Van Verth
Russell M. Taylor II
University of North Carolina at Chapel Hill

Adding Force Feedback to Graphics Systems: Issues and Solutions described the design of a new system that allows the virtual reality user to reach out and touch objects in a virtual environment and feel push back from the system without the latency that has made other systems impractical.

Superior Augmented Reality Registration by Integrating Landmark Tracking and Magnetic Tracking
Andrei State
Gentaro Hirota
David T. Chen
Bill Garrett
Mark Livingston
University of North Carolina at Chapel Hill

Superior Augmented Reality Registration by Integrating Landmark Tracking and Magnetic Tracking also addressed virtual reality performance issues. It looked at the combination of two new techniques that allow virtual objects to be placed more accurately into a view of a real scene than has been possible in the past.

Natural Phenomena

The Papers presented in this area addressed the greatest challenge in computer graphics: simulating the complex geometries, textures, and colors that are the result of forces of nature.

Visual Models of Plants Interacting with Their Environment
Radomir Mech
Przemyslaw Prusinkiewicz
University of Calgary

In Visual Models of Plants Interacting with Their Environment, the authors went beyond generating static images of plants and looked at how the natural shapes of plants evolve as a function of the availability of sunlight or water in a particular environment.

Modeling and Rendering of Metallic Patinas
Julie Dorsey
Massachusetts Institute of Technology

Pat Hanrahan
Stanford University

Modeling and Rendering of Metallic Patinas went beyond simply modeling the appearance of a new metal surface. Models simulated how the effects of atmospheric composition and rain result in changes in the appearance of metal objects over time.
