which "line"

The line in your model

there's many... sorry, I'm not trying to be difficult, I just really don't know which one you want :(

The last one

If u look.straight down it at a low height
..the line will start becoming unresolvable at some point

practical demonstration of that video Citizen linked

:6:40 time in video

6:42

Ohhhh, I see.... so it's the bluring of the chair there, that obscures the bit of the coin?

its on a table

oh, whoops

close enough

your angle is low enough to the ground that the ground is blocking the bottom of the coin

your viewing angle

I understand that now, okay.

that's only if the table is in front of the camera though

I am just assuming the picture I posted is someone on a beach zooming in

I would not say they put the camera on the ground

that would definitely mess with the shot

Simulating miles and miles of light angles on a table.

Thr video.shows coins on the table halfway

the table is right in the middle of the frame though

angle matters where they are viewing the ship, but eventually given enough water and area, the ship will eventually start to go over the fake horizon because of perspective and optics

zoomed out

its fake because you can zoom in to re-aquire it

zoomed in

this is a flat plane here

See the coins sitting on table. Right side

But with those, the camera is level with the table

@Fireflash you never take into account how light works

if the camera were higher, it would not matter

you're not taking into account the table

Dude

Its a demonstration on a table showing you how light works

You can see the bottom of the coin then you cant

you should go over the entire video
