Description: | Overcast lighting (indirect lighting / shadowing) (1 = light; 0 = shadow) |
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.
