Abstract
The emergence of non-photorealistic rendering (NPR) over the greater part of a decade has created an intriguing new eld espousing expression, abstraction and stylisation in preference to the traditional computer graphics concerns for photorealism. By lifting the burden of realism, NPR is capable of engaging with users, providing compelling and unique experiences through devices such as abstraction and stylisation. Many artistic and visual styles have been achieved by NPR including interactive and automated systems for drawing and painting. In this paper we outline the current state-of-the-art of NPR for visualisation and identify some current and future trends in NPR research.
