Ambient occlusion (AO) [Pharr and Green 2004] provides an approximation to global illumination. It can be computed in real-time if restricted to screen-space [Mittring 2007; Loos and Sloan 2010], at the cost of an approximation of solutions computed in geometric space, thus introducing a loss of quality.
