Introduced in Chapter 11 (on p. 323), this library extends UWB _ D3D _ Lib11 to
support scene node selection and collision. The SceneNode class is extended to
support the building of bounding volumes. The D3DDrawHelper class is extended
to support transforming a point by the top of the matrix stack.
In this case, changes are localized to the SceneNode and WindowHandler
classes ( Figure C.15 ) . The following files are modified from the previous version
of the library:

11.7, 11.8, 11.9,

12.1, and 12.2
