When light rays strike a surface, the surface reflects them, or at least some of
them, enabling us to see the surface. The appearance of a surface depends on
the light that strikes it combined with the properties of the surface material,
such as color, smoothness, and opacity.
Other factors, such as a lights color, intensity, attenuation, and angle of
incidence also play a role in how objects in a scene appear.
