Bezier surfaces suffer from the same limitations present in Bezier curves. In this chapter, I will explain how to build surfaces based on B-spline concepts. Many of the basic ideas will carry over from Chapter 7, "Basic Surface Concepts and Bezier Surfaces," but I will introduce the following new material:
Advantages of B-splines over Bezier surfaces
Extending B-spline curves to surfaces
Implementing B-spline surfaces
