The wizard of ethereal pictures and virtual places

Renaissance artists constructed pictorial space using algorithms based on Euclidean geometry. Computer artists use algorithms based on the analytic geometry of Descartes to compute pictures as well as the subjects in them. An examination of the workings of these two different types of algorithm reveals that the computer offers a radical new approach to making art, which is not yet well understood. Postmodern algorithms for picturemaking are more evanescent than their Renaissance counterparts because computers process information conceptually instead of storing it physically. The computer is neither a passive medium nor a pliant tool, but an active creative partner.
