One of the biggest differences for instance is axicon lenses which can produce non-diffractive beams.

The angle the light is coming to your eye dictates that closure

For a gaussian beam on a circular lens*

For other waveforms and other lenses, no

If you are closer to something...it will start to blend sooner than something further

Height can cause this

Or distance

Imagine the vertical lines are say light post and the point on the left is where the observers eyes would be

on a flat plane, we should still be able to see the whole ship

yet half of it is obscured.

Your not doing it right

Oh? please fix my diagram then haha

I could be wrong :v
So if you can diagram the picture

then by all means

You're not taking into account how light works at great distances

I just explained it to youm

how light works at great distances? the photon thing?

see how in this picture you're closer to the left side hallway and you start to lose the left first

perspective, you can only see so far, the sun is going in a circle covering all the land masses in a day, traveling in a circle, you can only see so far so you see it going over the see-able view in your area

how correct is this then

Dude

Are u seriously this dense?

I'm using the top of the bottom part of the arch as the plane

That's rude :(

No need for that

Youre not learning anyting

Youre just making bullshit drawings

diagrams really help me though

I'm sorry...

again in this picture The Observer is closer to the left side of the hallway and so you start to lose the left side first do you understand

Oh, of course. But you never fully lose the left side

Extend the hallway 3 miles

unless you're looking exactly on the plane of the left side

doesn't that seem like perspective to you Citizen? based on where you are things change.

Youre not thinking distance and angular resolution

But you never lose the left side, right?
