    2 What is ambient occlusion?


    Ambient occlusion represents non-directional shadowing of a scene / asset like overcast lighting.



    3 How do we get this result in realtime?

    3.1 Screen space ambient occlusion


    Screen space ambient occlusion is the indrectional shadowing of the raw geometry of a scene. It's a screen space post processing effect of the engine, procedurally generated. The detail amount depents on the raw geometry.


    === Ambient occlusion map ===
    With screen space ambient occlusion there are no indirect shadows in surface details. For that we need ambient occlusion information texture based. The resolution is an ambient occlusion map.
