What I mean
- By "seeing in 2D", I mean that what we see can be expressed in a 2D image
- In other words, we can only see the front of objects. We cannot see what is behind, or blocked
- We also have some distance data, which is what I mean by "pseudo-3D"
- I would consider "seeing in 3D" to be able to see all sides of an object at the same time
Why I'm bringing this up
- In most "flatland" or 2D movies/stories, the world is shown from our point of view and we can see the entire world at once
- The characters also behave as though they are able to see what we see - what's behind other objects etc.
- What they see should really be expressed as a line
