If we’re able to create the illusion of the 3rd dimension on our 2-dimensional screens, why aren’t we able to simulate/create the illusion of the 4th dimension in our 3-dimensional world?

Question

(I know, time is the 4th dimension. I mean 4 spacial dimensions)

Well, we certainly could with the help of holograms. It still wouldn’t be as convincing, though, since the nature of our vision and being in 3D space means we can only see 2.5 D, with partial 3D. Let me explain it like this: we can see every point on a finite 2D plane from our 3D perspective. However, you cannot do the same for a 3D perspective; you’re only seeing part of the 3D space right now (for example, you can’t see the insides of the device you’re reading any more than a drawing can see past an obstruction on paper). A 4D being would be able to see us and our world inside and out all at once, which would be conducive to creating an understandable pseudo-4D space within 3D. We’d need to he 4D ourselves to understand it, though. Until we can upload ourselves into a 4D computer simulation, it remains hard to understand even if a 3D representation of a 4D space were created.
