NURBS (Non-Uniform Rational B-splines) use a method of mathematically describing curves and surfaces that are well suited to 3D applications. NURBS are characterized by the smooth organic forms they produce.

NURBS surfaces can be quickly modeled and edited using a variety of techniques. NURBS surfaces are created using one or more NURBS curves that define the profile of the shape that you want for a surface, and then using a specific construction method to create the finished surface.

NURBS curves and surfaces have many applications and are the preferred surface type for industrial and automotive designers where smooth forms with minimal data are required to define a particular form. NURBS curves are ideal for defining a smooth motion path for an animated object. With NURBS, a surface can be modeled and then converted to a poly mesh.

In this chapter, you will learn some basic techniques for working with NURBS curves and surfaces in Maya. This chapter includes these lessons:

• Lesson 1 Revolving a curve to create a surface: Introduction
• Lesson 2 Sculpting a NURBS surface: Introduction
• Lesson 3 Lofting curves to create a surface: Introduction
