Represents a directional light source in a 3D scene. Directional light sources are treated as if they are located infinitely far away from the scene. A directional light source has only a direction vector, but no location. The effect of an infinite location is that the rays of light can be considered parallel by the time they reach an object. An example of a real-world directional light source is the sun. Directional lights are rendered faster than point lights and spot lights.
