Supports. The tutorials that
are based on this library:
Tutorials 7.4 and 7.5.

Introduced in Chapter 7 (on p. 189), this library presents the PrimitiveList
abstraction for coherently grouping primitives. The important change from the
previous library is the addition of PrimitiveList1.h/.cpp into the Primitives
subfolder of the Common Files folder.
Figure C.8 highlights the new and updated classes in this library. The follow-
ing files are modified from the previous version of the library:

Filename Purpose
Header Files folder: library header files
D3D _ Lib7.h header file for using this library
Common Files folder: API-independent files
Common Files/Primitives folder:
PrimitiveList1
