Proceedings of the 7th International Symposium on Non-Photorealistic Animation and Rendering

Welcome to NPAR 2009, the seventh International Symposium on Non-Photorealistic Animation and Rendering. As in 2007, this symposium is co-located with ACM SIGGRAPH, and takes place August 1--2, 2009, in New Orleans, Louisiana, USA. Non-photorealistic animation and rendering (NPAR) refers to techniques for visually communicating ideas and information. Such techniques usually generate imagery which is expressive, rather than photorealistic. The papers presented in this volume showcase new research on both the mechanisms of non-photorealistic animation and rendering techniques as well as principles of visual communication via such artistic animation and rendering. This research area continues to show great promise, as evidenced by the growing use of non-photorealistic techniques in film and games. This year we received 21 paper submissions, each of which was assigned to four members of the program committee. Papers for which one of the program chairs had a conflict were assigned and completely handled by the other program chair. After the end of the reviewing period, the reviewers of each paper discussed the reviews and ultimately came to a consensus on accepting or rejecting the paper. Several papers were accepted conditionally, in which case the authors were given the chance to address some required changes suggested by the reviewers. The outcome of this process is the set of seven papers that are collected in this volume.
