This is probably really dumb so I’ll try to explain what I mean.
If I’m playing BOTW, for example, and I walk past a tree so, from my camera angle, it is no longer visible, what does the computer do graphically to the data/information about that tree? I’m always just amazed walking round these incredibly detailed worlds and being able to move/change directions/change camera angles and the whole thing is usually seamless.

Usually, information about what is where with regards to environments is loaded in when the player is close by. Then the game calculates whether a given object is in the player’s camera view, and if it is, renders it. Rendering is by far the most computationally expensive part, so doing other math first to make sure you’re rendering only what the player needs to see is well worth it.
[This is what that looks like in Horizon Zero Dawn](https://media.giphy.com/media/xUPGcgiYkD2EQ8jc5O/source.gif), for instance.
