Group Objects

Overview

This chapter describes group objects and the functions you can use to manipulate them. You can use groups to collect objects into lists or hierarchical models, which you can draw or otherwise manipulate with group object routines.

To use this chapter, you should already be familiar with the QuickDraw 3D class hierarchy, described in the chapter "QuickDraw 3D Objects" earlier in this book.

This chapter begins by describing group objects and their features. Then it shows how to create and manipulate groups. The section "Group Objects Reference" provides a complete description of the group objects and the routines you can use to create and manipulate them.
