The SIGGRAPH 2005 Papers program is the premier forum for presenting the finest research in computer graphics and interactive techniques. A total of 461 submissions were received by the deadline and 98 Papers were selected for presentation at SIGGRAPH 2005. The leading contributors to this year's Papers program include: Microsoft Research, Massachusetts Institute of Technology, University of North Carolina at Chapel Hill, Stanford University, Mitsubishi Electric Research Labs, the University of Washington, Carnegie-Mellon University, California Institute of Technology, and ETH Zurich. "The SIGGRAPH Papers program constitutes the core of all SIGGRAPH programs," stated Markus Gross, SIGGRAPH 2005 Papers Chair from the Swiss Federal Institute of Technology. "It continues to define excellence in research in computer graphics and interactive techniques. It has long been the finest international forum for disseminating groundbreaking, provocative, and important new work -- this year is no different. From increasingly sophisticated simulation of physics to advanced picture and video processing, this year's program provides a full spectrum of topics and cutting-edge thinking. Our selection criteria follow the highest standards, are very rigorous and only accept outstanding innovations in our field. The acceptance number clearly demonstrates the large body of excellent research in computer graphics." According to Gross, three major trends are surfacing in the research arena. The first is that graphics researchers are bringing reality into the computer. Complex lighting and shading models are becoming "data-driven" or based on samples from the real world. He concludes that this advancement, for instance, makes it possible to alter and simulate the appearance of human faces photo-realistically. Given this development, novel camera and acquisition devices have been created. A second trend that the Papers Chair noted is the increasingly sophisticated simulation of physics. He points out that various Papers deal with simulation of the complex interaction of media, such as liquids, smoke, or gas, and solid materials. He also notes that various innovations make physics simulations interactive and real time on personal computers. "This is very important for the development of more realistic games and will be supported by novel hardware architectures and processing units to be released by the industry very soon," stated Gross. "In particular, novel chip generations and physics processing units will accelerate computations in computer games." He concludes that a third trend points toward advanced image and video processing. Specifically, the public will soon experience a variety of methods for panoramic stitching of videos, 3-D photo creation, and intelligent and user-friendly editing of video. According to Gross, such methods will soon become tools the public utilizes to take their home videos to an entirely new level. A Few Highlights From the SIGGRAPH 2005 Papers Program: Capturing reality deals with novel methods to bring reality into the computer by acquiring complex shape and appearance information from real world objects. This allows for unprecedented realism and novel effects in visual simulation.
