Ambient Occlusion

Ambient OcclusionAmbient Occlusion is a technique used in computer graphics to calculate the extent to which any given point in a three-dimensional scene is illuminated by ambient light. For example, in an outdoor scene, the sky is considered the source of ambient light. So, any given point in the scene may be assigned a value according to how exposed it is to the sky. More specifically, if you were traveling through a tunnel, the entrance would be more exposed to the ambient light of the sky, but deeper parts of the tunnel would be darker, or more occluded.
