Detailed Description

An interface class representing a directional light.

A directional light source illuminates all graphics elements equally from a given direction; it defines an oriented light with an origin at infinity. That is, a directional light source has a directional vector and parallel light rays travel along the direction. The directional light contributes to diffuse and specular reflections but does not contribute to ambient reflections.
