Expressive Rendering: A Review of Nonphotorealistic Techniques
IEEE Computer Graphics and Applications, May 1995
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.
