Managing Sets
A set object (or, more briefly, a set) is a collection of zero or more elements, each of which has both an element type and some associated element data. QuickDraw 3D provides routines that you can use to create a new set, get the type of a set, add elements to a set, get the data associated with an element in a set, loop through all the elements in a set, and perform other operations on sets.In general, you'll use the routines described in this section to handle sets containing elements with custom element types. You should use other QuickDraw 3D routines to handle sets that consist solely of elements with predefined element types. For example, to create a set of vertex attributes, you can use the
Q3VertexAttributeSet_Newfunction (to create a new empty set of vertex attributes) and theQ3AttributeSet_Addfunction (to add elements to that set). See the chapter "Attribute Objects" for information on managing attribute sets. See the section "Defining Custom Elements" on page 3-17 for information on handling custom element types.
