What is Ambient occlusion?

- Ambient Occlusion is related to bright the light to shine on specific surfaces.

- AO is based on the environment of the surface.

- The calculation is done by casting rays in each and every direction from the surface.

- The brightness is increased on the surface by focusing the rays from the background.

- Points with little geometry will appear light on the visible hemisphere.
