Prof. dr. Jan J Koenderink Department of Physics and Astronomy, Universiteit Utrecht, The Netherlands Jan Koenderink graduated in Physics and Mathematics in 1967 at Utrecht University. He moved to Experimental Psychology of the Universiteit Groningen, then in 1974 returned to the Universiteit Utrecht where he presently holds a chair in the Department of Physics and Astronomy. There he founded the Helmholtz Instituut in which multidisciplinary work in biology, medicine, physics and computer science is coordinated. He has received an honorific degree (D.Sc.) in Medicine from the University of Leuven and is a member of the Royal Netherlands Academy of Arts and Sciences. His present research interests include: psychophysics of human visual perception representation of spatiotemporal and material properties in the mind ecological optics computer vision and image processing multiscale representation differential geometry and singularity theory art historical research in image interpretation and pictorial representation Abstract: Geometry of Object Colors Because the colors of objects are only weakly correlated with the spectra of the corresponding beams of radiation is it commonly assumed that "object colors" are subjective entities and that they are properly discussed in psychological contexts only. However, it is very well possible to construct an entirely objective account of object color in the context of colorimetry. Colorimetry is an objective science because it only deals with judgments of indiscriminability, thus observers in colorimetric experiment never have to venture an opinion as to the "redness" or "greennes" of a particular beam. This apparent weakness proves to be a major strength because it allows one to do quantitative predictions. This science was pioneered by Maxwell and Grassmann in the mid 19th century and perfected by Helmholtz and Schroedinger around the turn of the century (1850's to 1920's). The theory of object colors has a history that runs from Goethe (18th c.) and Schopenhauer (19th c.) to Ostwald (1910's). Novel perspectives in colorimetry were disclosed by Cohen in the 1970's. Building on this work it is possible to frame an essentially geometric account of object colors that is far more sophisticated and useful than the standard accounts in current use.

Christopher Hery Lead Research & Development Engineer Industrial Light & Magic Christophe Hery joined Industrial Light & Magic in 1993 as a senior technical director on The Flintstones. Prior to that, he was working for Acteurs Auteurs Associes (AAA) studio in France setting up a CG facility devoted to feature film production. Christophe majored in architecture and electricity at Ecole Superieure des Travaux Publics, where he received his degree in 1989. While a student in Paris he freelanced as a technical director at BUF, a special effects house, as well as Thomson Digital Images. After graduation, Christophe took a job as director of research and development at Label 35, a Parisian cartoon studio. As a research and development lead, Hery has been working on skin research as well as supporting shaders and rendering issues. In 2003, Hery was the recipient of a Technical Achievement Award for the development of practical methods for rendering skin and other translucent materials using subsurface scattering techniques. He is currently working on a project on creating talking digital clones and all associated tools and developing processes. Abstract: Rendering evolution at ILM From Jurassic Park to Van Helsing, the rendering technologies have evolved over the last 10 years at ILM in order to sustain the high demands of our clients and public. State of the art rendering techniques such as volume rendering, ambient occlusion, image-based rendering, sub-surface scattering and global illumination are now in common use. This talk will give a survey of how rendering schemes came to be deployed (and fairly often pionneered) at our facility, and what challenges they brought with them.
