More self-tutoring about modern terms: the tutor shares what he learned about ambient occlusion.
a way of depicting a scene that shows features darker or lighter based on their exposure to ambient light, rather than a directed light source.
In many settings, such as within a dungeon or room in a deserted building, we often don’t imagine a light source. Therefore, the ambient lighting model makes sense.
Example: With ambient occlusion, a surface that crosses line of sight will be lighter than one running parallel to line of sight.
