Ambient Occlusion

Ambient Occlusion is how exposed each point in a scene is to ambient lighting. It's effect is that it darkens darkens enclosed and sheltered areas of the scene.

SSAO (Screen Space Ambient Occlusion) - 2007

Each full screen pass sample the depth around each pixel and a darkening value is computed based on depth differences. Sampling is done randomly in a sphere around each pixel.
