NPAR 2013 — Call For Papers Submission deadline April 7, 2013 We invite you to submit your work to NPAR 2013, the 11th international symposium dedicated to non-photorealistic animation and rendering, sponsored by ACM SIGGRAPH and in cooperation with Eurographics. Non-Photorealistic Animation and Rendering (NPAR) refers to computational techniques for visual communication. Such techniques usually generate imagery and motion which is expressive, rather than photorealistic, although they may incorporate realistic elements. NPAR 2013 is part of Expressive 2013, a joint symposium that combines NPAR with Computational Aesthetics (CAe) and Sketch-Based Interfaces and Modeling (SBIM). It will be co-located with SIGGRAPH and will take place in Anaheim, California, July 19th-21st, 2013. A single registration for Expressive 2013 will include all three symposia. The Expressive 2013 web site can be found at <http://www.cl.cam.ac.uk/conference/expressive-2013/> http://www.cl.cam.ac.uk/conference/expressive-2013/. We invite researchers, artists, and practitioners of all areas connected to non-photorealistic animation and rendering to submit papers and posters on their work. Submitted papers should be self-classified into one of the following three categories: • Research: new algorithms, scientific studies, analysis, or data (i.e., traditional NPAR papers) These must contain novel results that make a substantial contribution to the field. • Production: candid discussion of the process of creating a work (e.g., film, image, game) or art tool (e.g., paint or CAD program, software library). • Meta: statements about research that do not contain new results, e.g.: grand challenges, position papers, evaluation standards, surveys, and primers on art / aesthetics / psychophysics for a computer science audience. All work must be previously unpublished and contain a novel contribution. Production and Meta papers need not contain original research or results. Topic areas of the conference include but are not limited to: • Expressive character animation and physics • Abstraction and stylization of images/video • Interaction techniques • Accounts of real productions (e.g., animated films) • NPAR in real software products (e.g., modeling, visualization, presentation software) • Visual composition • Hardware acceleration • Evaluation methods for NPAR algorithms • Psychophysics of NPAR • Rendering and layout for text and presentation graphics • Quantitative analysis of human artists • Generative or evolutionary approaches • Style transfer • Temporal and spatial coherence • Adapting classic CG effects like motion blur, depth of field, and lighting for NPAR • Simulation of natural media and traditional styles • Non-traditional camera models • Position papers on grand challenges There is no absolute maximum length for paper submissions; please use the SIGGRAPH length guidelines, found here: <http://s2013.siggraph.org/submitters/technical-papers/publication-requireme nts/> http://s2013.siggraph.org/submitters/technical-papers/publication-requiremen ts/. In particular, note that papers longer than 8-10 pages must make a very significant contribution to be accepted. Papers should follow the ACM SIGGRAPH-sponsored conference formatting instructions ( <http://www.siggraph.org/publications/instructions> http://www.siggraph.org/publications/instructions), including a title page with an abstract and keywords, and a bibliography. Submission is electronic in PDF format; supplemental video and images may also be submitted. Research papers are reviewed double-blind and so must be anonymous when submitted. Meta and Production papers are reviewed single-blind and the author’s reputation and institution are a factor that reviewers may consider. Information on the submission process will be available on our website. Accepted conference papers will be published in the conference proceedings by ACM SIGGRAPH and will be available online via the ACM Digital Library. Posters will not be archived. Posters may be submitted in PDF format as either an extended abstract or as a draft of the poster itself. Rejected papers may be considered for the poster track. NEW THIS YEAR Presentation of work previously published in a journal: The intent of this change is to allow authors who prefer (or need) to publish their work in journal form the opportunity to present that work at Expressive. Requirements: The work should be published in the July 2012-July 2013 time frame, and not have been presented at a conference or symposium already. What to submit: A copy of the paper abstract and a link to the published paper or a pre-print of it. Submissions will be reviewed by the program committee for suitability of content. Note that accepted presentations are subject to the same rules as regular papers, namely that at least one author must register for the conference. Deadline: April 7, 2013. Technical artwork submissions: Last year, authors of accepted papers were invited to bring artworks made using their techniques to show at Expressive (this was different than the art show itself). We would like to extend this invitation again, but open it to all attendees. These artworks will be displayed at the Expressive venue. Requirements: The artwork should be related to recent technical work that falls under the Expressive umbrella. What to submit: A one-page abstract describing how the artwork was created, along with an image or video. Deadline: June 2, 2013. Unlike previous years, there will not be an official process to consider NPAR 2013 papers for journal publication. Merged program committee: Expressive 2013 will have a single, merged technical program committee. However, papers will still be submitted to one of the NPAR, SBIM and CAe symposia tracks and reviewed by that symposium's criteria. Posters, demos, and artwork: You are invited to submit to these programs at anytime before June 2nd; every effort will be made to return a response within two weeks. Important Dates Papers submission deadline: April 7th, 2013 Acceptance notification: May 13, 2013 Papers Camera-ready deadline: May 20, 2013 Poster/demo/talk/artwork submission deadlines: rolling notification, closes June 2nd, 2013 Conference: July 19-21, 2013 All deadlines are at 17:00 (5pm) Pacific Daylight Savings Time.
