The problems of graphic representation or plotting curves and surfaces are always apparent in computer-aided design (CAD) and computer-aided manufacture (CAM).

In this chapter, a number of mathematical techniques are explained among which a designer may choose the most appropriate to his specific problem and the computer availability (memory Author: Yvon Gardan.

Non-uniform rational basis spline (NURBS) is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces. It offers great flexibility and precision for handling both analytic (surfaces defined by common mathematical formulae) and modeled are commonly used in computer-aided design (), manufacturing (), and engineering.

Have you ever wanted to reach into your math book and turn a graph around with your bare hands. Then try out 3D Curves and Surfaces. It’s literally Math You Can Handle. Packed with movies, galleries, 3D interactives, explanations, and self-quizzes, this book will help you see how math and equations.

The book also deals with curves, because an understanding of curves is a key to understanding surfaces. Most mathematical methods for curves can be extended to surfaces, which is why this book covers various approaches to curve design and shows that many curve methods can be generalized to surfaces.

Free-form curves and surfaces represented by control points together with well-defined basis functions are widely used in computer aided geometric design. Efficient evaluation of points and derivatives of free-form curves and surfaces plays an important role in interactive rendering or CNC by: 3.
