Texturing and Modeling

A Procedural Approach

The third edition of this classic tutorial and reference on procedural texturing and modeling is thoroughly updated to meet the needs of today's 3D graphics professionals and students. New for this edition are chapters devoted to real-time issues, cellular texturing, geometric instancing, hardware acceleration, futuristic environments, and virtual universes. In addition, the familiar authoritative chapters on which readers have come to rely contain all-new material covering L-systems, particle systems, scene graphs, spot geometry, bump mapping, cloud modeling, and noise improvements. There are many new spectacular color images to enjoy, especially in this edition's full-color format.As in the previous editions, the authors, who are the creators of the methods they discuss, provide extensive, practical explanations of widely accepted techniques as well as insights into designing new ones. New to the third edition are chapters by two well-known contributors: Bill Mark of NVIDIA and John Hart of the University of Illinois at Urbana-Champaign on state-of-the-art topics not covered in former editions.An accompanying Web site (www.texturingandmodeling.com) contains all of the book's sample code in C code segments (all updated to the ANSI C Standard) or in RenderMan shading language, plus files of many magnificent full-color illustrations.No other book on the market contains the breadth of theoretical and practical information necessary for applying procedural methods. More than ever, Texturing & Modeling remains the chosen resource for professionals and advanced students in computer graphics and animation.

Professional game and game engine developers; real-time graphics and simulation developers; creators of movie special effects; computer graphics, geometric modeling, CAGD, animation, and visualization programmers and researchers pertaining to all applications of practical, artistic, entertainment, medical, military, manufacturing etc. products.

  • "This book has always been my favorite computer graphics book...The authors are the key inventors of the technology and some of the most creative individuals I know."?From the foreword by Pat Hanrahan, Canon USA Professor, Stanford University "This new edition updates the definitive book on the subject with 50% more material. Video game developers will be particularly interested in the demenstrations of procedural texturing and modeling on real-time hardware..."?Steve Anderson, CTO, Electronic Arts, Los Angeles "Texturing and Modeling, Third Edition has kept up with the latest technology and provides insight and instruction on how to best use it. I would recommend it to anyone as an introduction to procedural techniquest or as a comprehensive reference."?Doug Roble, Creative Director of Software, Digital Domain
