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.

Ray tracing NPR-style feature lines
We present an algorithm for rendering high-quality line primitives of controllable on-screen width within a ray tracing framework, which can render simple NPR-style feature lines, including silhouette edges, crease lines, and primitive intersection ...
Abstraction of 2D shapes in terms of parts
Abstraction in imagery results from the strategic simplification and elimination of detail to clarify the visual structure of the depicted shape. It is a mainstay of artistic practice and an important ingredient of effective visual communication. We ...
As-rigid-as-possible image registration for hand-drawn cartoon animations
We present a new approach to deformable image registration suitable for articulated images such as hand-drawn cartoon characters and human postures. For such type of data state-of-the-art techniques typically yield undesirable results. We propose a ...
Semiregular patterns on surfaces
Inspired by recent advances in high-quality mesh parameterization, I present a technique for decorating surfaces with seamless ornamental patterns. The patterns are transferred from planar drawings with wallpaper symmetry. I show that when the original ...

In this work, we focus on stippling as an artistic style and discuss our technique for capturing and reproducing stipple features unique to an individual artist. We employ a texture synthesis algorithm based on the gray-level co-occurrence matrix (GLCM) ...
Appearance-guided synthesis of element arrangements by example
We present a technique for the analysis and re-synthesis of 2D arrangements of stroke-based vector elements. The capture of an artist's style by the sole posterior analysis of his/her achieved drawing poses a formidable challenge. Such by-example ...
Airbrush simulation for artwork and computer modeling
A computerized airbrush system with a full three dimensional airbrush interface is presented. The position and orientation of an electronic airbrush tool is tracked in space, and, when the trigger is pulled, paint is sprayed onto two and three ...
