The Essentials of CAGD

This book is an elementary introduction to the concepts which can be used to model the letters in this book as well as the "actors" in Toy Story. It is intended for anyone who needs to learn the basic concepts of Computer Aided Geometric Design (CAGD).

Putting the G into CAGD, the authors provide a much-needed practical and basic introduction to computer-aided geometric design. This book will help readers understand and use the elements of computer-aided geometric design, curves and surfaces, without the mathematical baggage that is necessary only for more advanced work. Though only minimal background in mathematics is needed to understand the bookís concepts, the book covers an amazing array of topics such as Bezier and B-spline curves and their corresponding surfaces, subdivision surfaces, and NURBS (Non-Uniform Rational B-Splines). Also included are techniques such as interpolation and least squares methods.
