1. Assignment Goal:
   • To further the platform independence of the Graphics class.
   • To make the Effect into an instanced object.
   • To make the Geometry class into a general usage interfaced class.
2. Viewer Class:
   • By looking at the differences between the two Graphics files, I deduced which parts would need to be separated into a new class.
   • I decided to name the new class Viewer, as it had a lot to do with the way things were displayed.
   • The interface functions in cViewer.h:
     • InitializeViewer: Sets up the viewer object.
     • ClearFrame: Clears the back of the frame.
     • Render: Draws buffers to the screen.
     • CleanUp: Releases all owned objects.
   • These functions are defined twice each in cViewer.d3d.cpp and cViewer.gl.cpp.
3. Sizes:
   • cEffect:
     • x86 – 16 bytes
     • x64 – 12 bytes
   • cGeometry3D:
     • x86 – 16 bytes
     • x64 – 24 bytes
   • It may be possible to reduce sizes by switching to different types, but I am not entirely sure if this would be possible.
4. How I Did it:
   • The easiest way to combine different sections of code is to open them side-by-side.
   • Combining like pieces into a separate class, and marking differences for transplantation into platform-specific functions.
   • Deciding on what was necessary function parameters
