Particle Systems for Artistic Expression

Particle systems can be thought of as a general technique within the field of computer graphics for creating a wide range of effects. To illustrate the range of effects, this paper begins by quickly reviewing the existing research on particle systems in the field of computer graphics. It then discuss in more details two particular areas of particle systems research : first a technique for sculpting surfaces, and second a work in progress for an interactive art installation. A common goal of both projects is to provide flexible tools to aid in personal expression. The focus is to move away from the analytical and point and click style of interface, and towards a more humanistic interface which re-embodies the user in the physical world.

Biography

Dr. David Tonnesen's research interests are in computer graphics, shape modeling, virtual environments, human-computer interaction, and the confluence of art and technology. Recently he has been working with GMD, Germany and INRIA Rocquencourt, France researching the interactive sculpting of three-dimensional shapes in a virtual environment. While working in Hollywood he developed new computer models, based on the merging of physics and geometry, to create special effects for a number of feature length animated films. He has also worked with Digital Equipment Corporation's Cambridge Research Lab (now Compaq), Lawrence Livermore National Laboratories, Cray Research, and Alias|Wavefront, a leader in high end computer graphic software systems. He is participating in Starlab's new spin-off, the Foundation of Affordable Mysticism (FOAM) to help create interactive art installations. He received his Ph.D. in computer science from the University of Toronto.
