====Ambient lighting====
An ambient light source represents an omnidirectional, fixed-intensity and fixed-color light source that affects all objects in the scene equally (is omnipresent). During rendering, all objects in the scene are brightened with the specified intensity and color. This type of light source is mainly used to provide the scene with a basic view of the different objects in it. This is the simplest type of lighting to implement, and models how light can be scattered or [[reflection (computer graphics)|reflected]] many times, thereby producing a uniform effect.

Ambient lighting can be combined with [[ambient occlusion]] to represent how exposed each point of the scene is, affecting the amount of ambient light it can reflect. This produces diffused, non-directional lighting throughout the scene, casting no clear shadows, but with enclosed and sheltered areas darkened. The result is usually visually similar to an overcast day.
