Description of a light source that illuminates everything in a scene, regardless of the orientation, position, and surface characteristics of the objects in the scene. Because it illuminates a scene with equal strength everywhere, the position and orientation of the frame that an ambient light source is attached to are inconsequential. Multiple ambient light sources are combined within a scene.

in POV-Ray, an arbitrary amount of light added to an object to simulate the effects of ambient light. ( Language Reference) ( Exploration Tool)

Ambient lighting is a constant amount of lighting that is added to all other lighting.

Ambient light is nondirectional and distributed uniformly throughout space. Ambient light falling upon a surface approaches from all directions. The light is reflected from the object independent of surface location and orientation with equal intensity in all directions.

Ambient light, also known as "general light", is an overall level of lighting in your room. Ambient light should provide a comfortable amount of light to suit how the room is used.

A term used to describe the lighting or illumination in a scene that does not originate from any specific light source, direction, or object in the scene.
