Non-Photorealistic Rendering This course provided a working knowledge of techniques for non-photorealistic rendering (NPR). NPR may offer a more effective means of communication than photorealism, and for many applications provides a more natural form of visual expression. From the artist's perspective, the course covered approaches that support the effects of natural media, such as pencil, oil painting, or watercolor that are derived from a range of 2D and 3D algorithms.   Topics included details of a range of techniques for generating NPR imagery, including pen and ink and sketchy styles, using both interactive and off-line approaches.   Organizer Stuart Green LightWork Design Ltd.   Lecturers Cassidy Curtis Pacific Data Images   Bruce Gooch Amy Gooch University of Utah   Stuart Green LightWork Design Ltd.   Aaron Hertzmann New York University   Pete Litwinowicz RE:Vision   David Salesin University of Washington   Simon Schofield Miller Hare Ltd. and University College London
