Pick Objects


This chapter describes pick objects and the functions you can use to manipulate them. You use pick objects to get a list of objects in a view that intersect a specified geometric object (for example, objects the user has selected in an image on the screen).

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.
