DirectionalLight
DirectionalLight creates parallel light rays to illuminate geometric shapes. Light is scoped and only illuminates geometry within its enclosing parent group! No source location is needed since rays are parallel from an infinitely distant source. DirectionalLight nodes do not attenuate with distance. Lights have no visible shape themselves and shine through occluding geometry. Hint: animate direction to simulate time-of-day sunlight effects. Hint: HeadLight is controlled by NavigationInfo. Interchange profile hint: light might not be scoped by parent Group or Transform.
