Relighting is an interesting method that is often used in video post production pipelines.
Given the vector of its surface normal, it is possible to calculate the brightness of each pixel by a pseudo 3D lightning system.

Screen Space Ambient Occlusion or SSAO is a method to compute an approximated AO pass in real-time!
This is done by using the depth information of a 3D object or scene that has been stored from the Z-(depth) buffer of the renderer.
