Non-Photorealistic Computer Graphics: Modeling, Rendering and Animation by Thomas Strothotte, Stefan Schlechtweg



Even as developments in photorealistic computer graphics continue to affect our work and leisure activities, practitioners and researchers are devoting more and more attention to non-photorealistic (NPR) techniques for generating images that appear to have been created by hand. These efforts benefit every field in which illustrationsthanks to their ability to clarify, emphasize, and convey very precise meaningsoffer advantages over photographs. These fields include medicine, architecture, entertainment, education, geography, publishing, and visualization.

Non-Photorealistic Computer Graphics is the first and only resource to examine non-photorealistic efforts in depth, providing detailed accounts of the major algorithms, as well as the background information and implementation advice readers need to make headway with these increasingly important techniques.

Already, an estimated 10% of computer graphics users require some form of non-photorealism. Strothotte and Schlechtweg's important new book is designed and destined to be the standard NPR reference for this large, diverse, and growing group of professionals.

*Hard-to-find information needed by a wide range and growing number of computer graphics programmers and applications users.

*Traces NPR principles and techniques back to their origins in human vision and perception.

*Focuses on areas that stand to benefit most from advances in NPR, including medical and architectural illustration, cartography, and data visualization.

*Presents algorithms for two and three-dimensional effects, using pseudo-code where needed to clarify complex steps.

*Helps readers attain pen-and-ink, pencil-sketch, and painterly effects, in addition to other styles.

*Explores specific challenges for NPRincluding "wrong" marks, deformation, natural media, artistic technique, lighting, and dimensionality.

*Includes a series of programming projects in which readers can apply the book's concepts and algorithms.

From the Back Cover

In the past decade, the field of non-photorealistic computer graphics (NPR) has developed as the product of research marked by diverse and sometimes divergent assumptions, approaches, and aims. This book is the first to offer a systematic assessment of this work, identifying and exploring the underlying principles that have given the field its cohesion. In the course of this assessment, the authors provide detailed accounts of today's major non-photorealistic algorithms, along with the background information and implementation advice you need to put them to productive use. As NPR finds new applications in a broadening array of fields, Non-Photorealistic Computer Graphics is destined to be the standard reference for researchers and practitioners alike.
