Figure C.6. UWBGL _ D3D _ Lib5 : Primitive hierarchy.

UWBGL_D3D_Lib6

Supports. The tutorial that is
based on this library:
Tutorial 7.3.

Introduced in Chapter 7 (on p. 185), this library presents the BoundingVolume
abstraction to support collision behavior for the Primitive hierarchy. A new
BoundingVolumes subfolder is defined in the Common Files folder for the new
source files. All source files in the entire Primitive hierarchy are updated to
support BoundingVolume collision behavior.

Figure C.7 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 folders: library header files
D3D _ Lib6.h header files for using this library
Common Files folder: API-independent files
Common Files/BoundingVolumes folder:
Intersect1 defines bounding volume hierarchy to support collisions
Common Files/Primitives folder: abstraction of primitives
all primitives are updated to support bounding volumes:
Primitive2 , PrimitivePoint2 , PrimitiveLine2 , PrimitiveCircle1
