VlSFILES Interactivity is the Key to Expressive Visualization Eric B. Lum and Kwan-Liu Ma University of California, Davis Scientific visualization is widely used for gaining insight into phenomena through data exploration and creating imagery that can be used t o i l l u s t r a t e these phenomena t o others. Interactive rendering has long been valued in visualization as a means of facilitating more effective e x p l o r a t i o n . More recently, non-photorealistic rendering (NPR) has been applied to scientific visualization, which consists of using artistically inspired techniques for the creation of more expressive visualizations [3, 4, 5]. In many cases, NPR has been shown to be more effective than photorealistic rendering in communicating subtle information about physical structures or phenomena. How the user chooses to portray a data set can have a significant effect on how accurately and efficiently a visualization communicates the information the user seeks to reveal. It is our belief that when NPR is made interactive, particularly with respect to the control of how NPR is applied, the user is able to more quickly derive expressive visualizations. I n t e r
