You are invited to participate in NPAR 2009, the 7th international symposium dedicated to non-photorealistic animation and rendering, sponsored by ACM SIGGRAPH and in cooperation with Eurographics. For the second time, NPAR will be co-located with SIGGRAPH which in 2009 takes place in New Orleans. This will allow us to raise attention for this important field, to open it to new people from academia, arts, and industry. Once again NPAR will bring together researchers and practitioners to showcase cutting-edge research in non-photorealistic animation and rendering systems and techniques.

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. We seek new research on both the mechanisms of non-photorealistic rendering techniques as well as the principles of visual communication via such artistic rendering. Specific themes of the conference include, but are not limited to:

* Simulation of traditional and new graphical styles
* Simulation of natural media
* Hardware-accelerated non-photorealistic algorithms
* Level-of-detail in image space
* Abstraction and composition in rendered images
* Synthesis of stroke-based patterns
* Style transfer
* Automatic painting from photographs and video
* Temporal and spatial coherence in non-photorealistic rendering
* Motion blur and depth of field in non-photorealistic images
* Lighting models for NPAR
* Non-traditional perspective
* Non-photorealistic modeling
* Animation systems
* Computer-aided cartoon animation
* 2D/3D integration
* Live-action integration
* Computer-aided in-betweening
* Computer-aided layout
* Matting and compositing
* Image-based rendering
* Rendering languages and systems
* Practical NPAR applications
* Evaluation methods for artistic graphics
* Computer-generated abstract art

We invite researchers and practitioners of all areas connected to non-photorealistic animation and rendering to submit papers. Full-length papers are the primary medium for conveying new research results at the NPAR symposium. Submissions are sought that describe original, unpublished work on all themes listed above.

Paper submissions should be at most 5000 words or 10 ACM conference pages in length. The title page should include an abstract (fewer than 200 words) and keywords. The submission is electronic in PDF format; supplemental video and images may also be submitted. Submission is single-blind, so papers may be submitted in «camera-ready» format. We recommend that prospective authors consult the SIGGRAPH publications page for information on paper formatting for paper submissions. The accepted papers will be published in the conference proceedings by ACM SIGGRAPH and will be available online via the ACM Digital Library.
