See how the camera is closer to left side of hallway

Yeah

The pillars start to blend together faster on the side the observer is closest to

Ok

You can see more of the pillars on the ones further away

Thats because the angular resolution

You're able to distinguish them anyway

Another example

The pillars are still there, it's just hard to tell one from another

Closer to left

It doesn't make the hallway appear to be curving

You lose the objects you are closer to first

The ocean doesnt curve either

There is a difference between losing an object and not being able to distinguish it from other objects

You are just losing what's closest to you first

The human eye has angular resolution limit of .02 degrees

Once the light hits the retina at .02 degrees resolution the object is no longer reasolvable

You dont lose the entire object all at once

Just the part that reached the resolution limit

As it gets further away, the angle will continue to become more shallow

Ah ok now I see

Until it all disappears

So for example if there was something sticking out from between two of the farther pillars you would see it

It appears like there is a curve

Yes you would see things sticking out

Ok I'm following

Its called gradiant slope or optical slant

Imagine looking at a painting on the wall

Then go up to the wall and look down the wall

You would only see the frame

The angle is gone

So as an expansion of that, say the hallway went as far as the eye could see, until the left pillars melded with the right

And there were mini sails sticking out from between the pillars on the left

At the same distance

Right so if you put a boat going down the hallway...you would lose the portion you are closest to first

It would need to be a very long hallway

Miles and miles

Hmm ok

How does the sail disappear so fast then
