UWBGL_D3D_Lib3

Supports. The tutorials that
are based on this library:
Tutorials 5.4, 5.5, and 5.6.

Introduced in Chapter 5 (on p. 141), this library modifies the previous version
to support multiple view/controller pairs and to provide a more comprehensive
utility functionality.
The important changes are in the GraphicsSystem class, where we added
functions for creating and activating swap chains, D3D's mechanism for support-
ing multiple drawing areas on the application window.
Figure C.3 highlights the updated GraphicsSystem and WindowHandler
classes, and Figure C.4 depicts the new utility classes in this library. The fol-

lowing files are modified from the previous version of the library:
