This tutorial surveys the state-of-the-art techniques for interactive non-photorealistic rendering with an emphasis on applications to volume visualization. This first section begins by giving a general motivation behind the need for interactivity in NPR and discusses some of the general approaches toward achieving high-speed rendering. The second section surveys methods that have been developed for interactive non-photorealistic rendering of polygonal surfaces, the area where the vast majority of the research in the field has been devoted. The third section describes an approach for how nonphotorealistic rendering can be applied to interactive volume visualization, while the fourth section concludes this tutorial.
