Ouvrage 9781558604469 : SUBDIVISION METHODS FOR GEOMETRIC DESIGN

The world's leading animation houses rely increasingly on subdivision methods for creating realistic-looking
complex shapes. However, until now there was no one book devoted to this powerful geometric modeling
technique. Subdivision Methods for Geometric Design does the job with authority and precision, providing all that
is needed to understand how subdivision works its magic, and how to make that magic work.
Throughout the book, icons cue readers to visit a companion Web site loaded with interactive exercises,
implementations of the book's images, and supplementary material. Rich in theory, analysis, and practical
information, this book is the complete resource for subdivision methods.
Features
The result of a collaboration between a leading university researcher and an industry practitioner.
The only book devoted exclusively and comprehensively to this important new technology.
Provides solid background and theoretical analysis of subdivision as well as a wide variety of specific
applications.
Addresses algorithms for Bezier and uniform B-Spline curves, Catmull-Clark subdivision for quad meshes,
and regularity tests for polyhedral meshes.
Via the companion Web site, (www.subdivision.com), provides opportunities for readers to experiment
hands-on with implementations in a richly interactive environment.
Includes a foreword by Tony DeRose, recipient of the 1999 ACM Computer Graphics Achievement Award
for his seminal work in subdivision methods.
Author Biography: Joe Warren, Professor of Computer Science at Rice University since 1986, is one of the
world's leading experts on subdivision. Of his nearly 50 computer science papers-published in prestigious forums
such as SIGGRAPH, Transactions on Graphics, Computer-Aided Geometric Design, and The Visual
Computer-a dozen specifically address subdivision and its applications to computer graphics. Prof. Warren
received both his M.S. and Ph.D. in Computer Science at Cornell University. His research interests focus on
mathematical methods for representing geometric shape.
Henrik Weimer is a research scientist at the DaimlerChrysler Corporate Research Center in Berlin, where he
works on knowledge-based support for the design and creation of engineering products. Dr. Weimer obtained his
Ph.D. in Computer Science from Rice University.
