Focus On Curves and Surfaces (Focus on Game Development) (Paperback)

~ Kelly Dempski (Author)

Editorial Reviews

Product Description

This is the only curves and surfaces book for beginners. It provides clear, practical explanations of curves and surfaces with the minimum of esoteric mathematical notation, making it far more accessible. You will be able to work along with the material for a better understanding of the concepts and a working knowledge of practical applications. Focus on Curves and Surfaces splits the material in two sections. The first part walks you through several forms of curves and surfaces explaining lines and functions of the equations. The next part moves from simple planes to complex surfaces so you can learn how to render surfaces using smoothing and simplification.

5.0 out of 5 stars Excellent introduction, February 19, 2003

By A Customer

This is a first review I am ever writing. I was looking for a book that would give a clear explanation of bsplines and nurbs in an easy and intuitive way and found this book to serve the purpose perfectly. Highly technical books skip these concepts and go into complex mathematical concepts assuming that the reader has a perfect background. This book does not assume this. Along with explanation it also gives why this particular method is beneficial and the weaknesses of it. This is also good for those who are already familiar with the subject but like to teach it to others. I wish the author could take other complicated methamatical topics and explain them also at this level clearly outlining their use in the industry like Fourier transforms, Z transform, Wavelets etc. Computer Graphics and Computer Aided Geometric Design are fields of highly sophisticated mathematics and we need books like these for every topic.

4.0 out of 5 stars Easy to Follow, November 28, 2004

By	Christopher Forseth "Topher" (Champaign, IL) - See all my reviews

The book is great on giving people an intuitive grasp on what a B-Spline or NURB is, allowing people to look at series of points and knowing "sorta" what the curve will look like.

The only serious lacking point is it's explanation of Knot Vectors and the reason they're ordered the way they are and what the numbers in them represent. It's a tricky subject to explain though, and the author made a good effort, but really needs to explain what the numbers DO persay. (Though if you play with the source and have a good eye it eventually makes sense). Anyway, excellent book and is the reason I'm the only person in my 3D Graphics class who knows how NURBS work (teacher included... "Just download code off the internet" he says, sheesh).

Anyway, BUY! It be good!
