UWBGL_D3D_Lib10

Supports. The tutorials that
are based on this library:
Tutorials 10.9, 10.10, 10.11,
10.12, 10.13, 10.14, 11.1, and
11.2.

Introduced in Chapter 10 (on p.e 276), this library presents the support for coordi-
nate systems, in particular the definition and manipulation of the world coordinate
(WC) window. The WindowHandler class is extended to support the definition
of the WC window and programming of the M w 2 n operator. The D3D subclass
D3D _ WindowHandler is also updated to reflect the changes.
Figure C.13 shows that the LoadW2NDCXform() function is defined in Window
Handler and implemented in D3D _ WindowHandler . The following files are mod-
ified from the previous version of the library:

Filename Purpose
