Because some Bay Area sites get their news feeds from outside the BA, I'm reposting the announcement of our November meeting. - Bruce --------------------------------------------------------------------- The Bay Area chapter of ACM/Siggraph - the Special Interest Group on Computer Graphics and Interactive Techniques - invites everyone to attend its November meeting: ARTISTIC DEVICES AND PHOTOREALISM IN SCIENTIFIC VISUALIZATION Marc Levoy Computer Science Department Stanford University 8:00 pm Tuesday, Nov. 27 Xerox PARC Auditorium 3333 Coyote Hill Road Palo Alto, CA The scientific and medical communities are deeply divided over the merit of incorporating artistic devices and photorealism into data visualizations. Techniques such as metallic shading, shadow- casting, surface and solid texturing, and selective defocusing are common in hand-drawn illustrations, but their use in computer- mediated data exploration is not widely accepted. Marc will argue that these techniques, if properly used, improve spatial comprehension and hence the utility of computer-generated visualizations. To illustrate his argument, Marc will describe the application of volume rendering - a technique for displaying sampled 3D data - to two problems: 1) interpretation of molecular electron density maps; and 2) planning of radiotherapy for cancer patients. Marc Levoy is an assistant professor of computer science and electrical engineering at Stanford University. He holds an M.S. degree in computer graphics from Cornell University and a Ph.D. in computer science from the University of North Carolina. Levoy headed the Hanna-Barbera Studios Computer Animation project for several years and has chaired two courses at Siggraph on computer animation. His current research interests include scientific visualization, volume rendering, medical imaging, and molecular graphics. * Directions to Xerox From 280, take the Page Mill Road exit. Take Page Mill 1 mile east to Coyote Hill Road. Follow Coyote Hill 1/2 mile, and Xerox will be on the left. Follow the signs to the auditorium and visitor parking area. From 101, take the Oregon Expressway exit west 2 miles to El Camino Real. Oregon Expressway becomes Page Mill Road at El Camino Real. Follow Page Mill Road 1.7 miles to Coyote Hill Road and turn left. Go 1/2 mile and Xerox will be on the left. Follow the signs to the auditorium and visitor parking area. The auditorium entrance is at the north end of the building, at the bottom of the stairs. * About Bay Area Siggraph Meetings Bay Area Siggraph meetings are free and open to everyone.
