Opis

cross-disciplinary perspectives of its participants. For example, Marc de Mey, a psychologist, used threedimensional computer graphic ren dering to reconstruct Masaccio's Trinity, in order to understand this early Renaissance painter's use of perspective; Thomas Hubbard, a photo journalist, engaged the entire audience in interactive image analysis; or Robert Williams, a computer scientist and musician, who performed Mussorgsky's Pictures at an Exhibition on a com puter assisted classical guitar, demonstrating a guitarist's ability to translate simple gestures for enhanced sonic expression. Each paper in this proceedings is a point on the perceptual hori zon. Together they form a Gestalt that organizes the visual land scape, highlighting reconverging paths of art, science, and technology toward a future Renaissance. Just as the fifteenth century Renais sance painter reinvented the technology of perspective to organize and represent images, future Renaissance communicators will rein vent computer technology to help us better understand visual reality. This conference would have not been successful without support from a few dedicated individuals. Specifically, I would like to thank Jean Coppola (conference coordinator), the NYC ACM SIGGRAPH board of directors, Dr. Carol Wolf (Chair, Computer Science Depart ment), Kenneth Norz (Assistant Dean), Dr. Susan Merritt ( Dean, School of Computer Science and Information Systems), and the di rector and staff of Pace University's Downtown Theater. 1.1 REFERENCES 1] Barlow, H., Blackmore, C., and Weston-Smith, M.
