If you are somewhat of a computer graphics expert, you may find this book a good reference on the "math" of surface, curves, etc. However, in that case, you would still probably be better off getting one of the author's other books.

Also, this is not a computer graphics book. You will not find anything about 3D viewing, graphics pipelining, rendering, or anything like that. It's strictly computer-aided geometric design.

Delivers exactly what the title says...  Jun 05, 2003 By Noiruuk
This is a great book that delivers exactly what the title says, the "essentials". I used this book for a CAGD class (taught by one of the authors) and found the material very readable, straightforward, and useful. In fact, I found myself returning to this book as a reference in later graduate level coursework in CAGD.

The book attempts to give the reader all the tools that are necessary to get started in CAGD, and I strongly believe it succeeds in doing that. From the very first chapter, which reaches all the way back to descriptions of points and vectors, to the end of the book, which introduces the reader to some of the same methods that are used in Computer Graphic Animation (composite surfaces) and CAD/CAM (NURBS), the book provides just about everything necessary to learn the material.

With the material I learned in this book, I created some very cool looking models...the kind of things that got "ooh's" and "aah's" from my friends, and most of all made me feel like the methods used to create animated films are not beyond me.

To the first reviewer, I'd say go back and re-read the first two chapters that describe points, vectors, lines, and planes. Although if someone isn't comfortable with linear algebra and vector math, then that would make tackling any form of CAGD or graphics difficult. As far as graphics knowledge necessary, the methods in this book can be applied by only knowing how to draw lines on the screen.

It's a great book I'd recommend to anyone interested in CAGD!

CAGD for Designers  Jun 04, 2003 By Dhiraj Nahar
I am a Mechanical Engineer with interest in CAD/CAM/CAGD/CAE areas. I have learnt CAGD from different classes at school and by far "The Essentials of CAGD - by Dr. Hansford and Dr. Farin" has been the easiest to understand. It gives you a very compact knowledge of this vast and challenging field. The math is very well laid out and several examples have been solved to explain the fundamentals. The other CAGD books by the same authors give a deeper understanding of CAGD principles. This book is like a bible to designers, people in graphics, finite elements, CAD/CAM, artists, stylists!


Great learning resource  Jun 19, 2003 By Brad Miller
This book does a really good job at presenting the concepts and methodologies of CAGD in a manner that is easy to learn from. You leave this book with a complete understanding of the how and why of the topics it presents.

The first reviewer complained that complete algorithms are not always given. The book is not meant to be a listing of algorithms to copy. If that's what you're looking for, you should look elsewhere. What this book does is presents the mathmatics and mechanics behind CAGD. It gives enough of the algorithm to start your implementation once you understand the topic. This promotes a fuller understanding of the subject and the theory behind, allowing you to apply the knowledge in domains outside of the subject area.

If you want to learn the basics of CAGD and have a good background in linear algebra and vectors (a must for any graphics programming), I'd highly recommend this book.
