  abstract = {In parallel with the well-known developments in computer graphics
              to produce photorealistic imagery there have been a number of
              interesting attempts to widen the range of output possibilities.
              In particular, there has been a thrust towards creating systems
              that simulate the sort of natural media that artists use. Some of
              these attempts are reviewed and, from them, the concept of
              'expressive' or non-photorealistic rendering is developed.
              Expressive rendering goes further than simulation of natural
              media: it aims to encourage new forms of image-making. Some of the
              possibilities are illustrated by output from the Piranesi
              system.},
