Group Objects Routines

Getting Group Positions

QuickDraw 3D provides routines that you can use to move forward and backward through the objects in a group. You do so by finding the currently occupied group positions in the group and then determining which objects occupy those positions. This section describes the routines you can use to find the valid positions in a group.
