To use this chapter, you should already be familiar with the QuickDraw3D class hierarchy, described in the chapter "QuickDraw 3D Objects" earlier in this book. For information about views, see the chapter "View Objects" in this book. You do not, however, need to know how to create or manipulate views to read this chapter.
This chapter begins by describing pick objects and their features. Then it shows how to create and use pick objects. The section "Pick Objects Reference," beginning on page 15-17 provides a complete description of pick objects and the routines you can use to create and manipulate them.
