Myths & truths of volume graphics
Wednesday April 21 2004 — 7:30 PM
Volume Graphics is an area of Computer Graphics dealing with points and objects made of points. This seeming lack of descriptiveness turns out to be very powerful in describing many natural and complex phenomena from weather patterns to fuel cells to our human body.
Within the 3D graphic industry, there are many myths surrounding the use and effectiveness of volume graphics and its voxel representation. The most common – that voxels produce poor image quality and slow performance, require a lot of memory and are not amenable to compression – prevent many applications from seriously considering voxels as a viable representation for their needs.
In this presentation, Torsten Möller and Andrew Woo will give an overview of the field of Volume Graphics, examine, and dispel the most common myths associated with voxel technologies, from an academic and industry perspective, respectively. Further we will give an overview of the current state of the art in Volume Graphics.

Torsten Möller is an assistant professor at the School of Computing Science at Simon Fraser University. His research interests include the fields of Scientific Visualization and Computer Graphics, especially the mathematical foundations of visualization and graphics. He is codirector of the Graphics, Usability and Visualization Lab and serves on the Board of Advisors for the Centre for Scientific Computing at Simon Fraser University. He has been appointed Vice Chair for Publications of the IEEE Technical Committee of Visualization and Graphics. He received his PhD in Computer and Information Science from Ohio State University in 1999 and a Vordiplom (BSc) in mathematical computer science from Humboldt University of Berlin, Germany. Torsten is a member of IEEE, ACM, Eurographics and CIPS and currently a Siggraph Vancouver volunteer.

Andrew Woo is director of engineering at NGRAIN Corporation, a leading developer of interactive 3D visualization and simulation software tools based in Vancouver, British Columbia. Prior to NGRAIN, Andrew was senior R&D manager at Alias|Wavefront, having worked on Sketch!, PowerAnimator, Studio, and Maya (which received an Oscar for technical achievement in March 2003). Andrew received a B.S. in computer science and commerce at the University of Toronto in 1987, and a M.S. in computer science at the University of Toronto in 1989. Andrew’s professional interests include rendering and visualization techniques, and he has published papers on rendering and visualization in the domains of CAD, video, film, e-learning, dynamic simulations, etc. Andrew was the treasurer of the Toronto SIGGRAPH Chapter in 1989-1992, and is currently the acting chair in the Vancouver SIGGRAPH Chapter. Andrew is a member of ACM, IEEE and CIPS.
