This sample demonstrates how mip-mapping works under Direct3D
by tiling a single textured quad across a 25x25 unit area.
The original texture is simply white with a thin black
border, but in a effort to show mip-mapping in action,
several mip-map levels have been altered by replacing the
auto generated mip-map texture for that level with a color-coded
version. This causes mip-map filtering to produce rainbow
colored bands which radiate across the surface as the eye
point moves about. Check out the OpenGL source
code page for the OpenGL equivalent of this sample.
