Overview

The previous chapters introduced you to several forms of curves of increasing complexity. This chapter backtracks to Bezier curves in order to introduce some basic surface concepts using the simplest of the three previously discussed parametric forms. As you'll see, surfaces can be quite straightforward once you understand the basic curve concepts. This chapter will serve as a foundation for the next few chapters by introducing the following concepts.

  • Extending curves to patch surfaces

  • Finding the normal vector for a point on the surface

  • Lighting a surface

  • Using the simple 3D-viewing framework

  • Setting up a basic 3D patch

  • Implementing Bezier patches
