In this program, we let a white light shine on a sphere with a diffuse color of blue and a specular color of light
blue with a specular power of 10. The default specular power in PhongMaterial is 32.0. Therefore our sphere does
not have as focused a highlight as the default. When the program in Listing 10-7 is run, the Specular Color Example
window shown in Figure 10-8 is displayed.

Adding Texture to 3D Shapes
The diffuseMap and the specularMap serve the same purpose as the diffuseColor and specularColor , except
that the maps provide different color values for different points on the surface of a 3D shape. The bumpMap and the
selfIlluminationMap are similarly mapped to the points on the surface of a 3D shape. The selfIlluminationMap
provides colors that will shine through even if no light is illuminating the 3D object. The bumpMap does not contain
color information at all. It contains normal vector information (which just happens to be three numbers, which can
be encoded as an RGB color) for each point of the surface, which, when taken into account during the color rendering
calculation, will result in a bumped look.
