Style Objects

Overview

This chapter describes style objects (or styles) and the functions you can use to manipulate them. You use styles to specify some of the basic characteristics of a renderer. For example, one renderer style determines whether an object is drawn as a solid filled object or as a set of edges. Another renderer style determines whether a surface is drawn smoothly or as a set of polygonal facets.

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. For information about renderers, see the chapter "Renderer Objects" in this book. You do not, however, need to know how to create or manipulate renderers to read this chapter.

This chapter begins by describing style objects and their features. Then it shows how to specify the current rendering styles of a model. The section "Style Objects Reference" provides a complete description of style objects and the routines you can use to create and manipulate them.
