meaning of Ambient Occlusion

Ambient Occlusion meaning in Computer Science Dictionary

Ambient Occlusion is a method utilized in computer system visuals to determine the extent that a point in a three-dimensional scene is illuminated by background light. For example, in a backyard scene, the sky is considered the supply of background light. Therefore, a point in the scene might assigned a value based on how subjected it's into the sky. More specifically, if perhaps you were traveling through a tunnel, the entrance would be much more subjected to the background light associated with the sky, but deeper areas of the tunnel would-be darker, or maybe more occluded.
