Ambient Occlusion

Ambient Occlusion is a geometry-based shadow rendering technique that creates soft, realistic shadows by calculating surface exposure to ambient light.
 

What is Ambient Occlusion

Ambient Occlusion is a shadow rendering technique that is usually dependent on the geometry instead of a light source. It's used to calculate soft shadows in areas where surfaces are close together.

How It Works

Ambient Occlusion works by calculating how a surface is exposed to the ambient light. The basic rule is: the closer other objects or occluders are to the surface, the darker it becomes.
