3D Cliffs Of Dover Pictures

that green screen apply the very same concept from your cave:

it renders the right perspective from the observer-camera point of view

if games did that which is posible with headtracking and you added it 3d you couldnt tell the difference from the game to looking at real life from a window

ive seen refered johny lee efect on tv as cheap 3d

and your rgiht moving sidways increases your depth perception is very tipical on movies

Its not the same:

cave/FullFOVglasses chroma/cinena game3D cinema3D johny system

stereo V X V V X

fov V X X X V

scale V X X X V

movement V X V X V

edit:
I made a nice table... but the format does not save it.


In a cave you have stereo, matching fov, scale and movement.
In a normal cinema, even with chroma, you have nothing of this. The perspective of the chroma fits the whole image, but not your own perspective or point of view.
In a game 3D you can have stereo, matching fov and movment, but not scale ( unless using the window mode I talked about in the later post that would made the game unplayable because of the zoom )
In cinema 3D you have stereo, but you can not match the fov, scale or movement.
In Jony system you match fov, scale ( with the limit of the screen wich is a limit that does not exist in a cave ) and movement, but not stereo.

yes i think we agree

the cave its like being there johny lee system like looking there through a window

on the other topic i cant tell for others

but i have never seen reality like in a 3d movie except for brief seconds during my life though according tests my binocular vision works

on the other hand the wikipedia explain stereopsis as triangulation, THIS IS WRONG,

from the superposition with each eye of \ and / your brain builds I in depth, that is how it really works

Yes, but the johny system is worse than looking trough a window, as it not provides two different images. It can completely fool you if you are far away from the screen so that the two images were almost the same, but if you come close to the screen the effect is lost.

The problem with cinema is that is not capable to match all parameters that your brain needs to be completely fooled as it only can offer stereo, but nothing more. So the brain do what it can do with that information and makes you feel a sensation that is not the same from reality. Like when you cross your eyes in reality providing the brain wrong information. It´s a kind of new sensation we called 3D because we need to call it with some name and 3D sounds cool. Also cinemakers want you to feel that new sensation so they exaggerated it to be more noticieable and people say ohhh, ahhhh.... nothing more. They call that real 3D but is not. You know what real 3D is when you have tryed a cave. Then you know that a real 3D is possible and is far away from the 3D cinema experience.

Of course the 3D feel like any other feeling or sensation is "brain made". I think wikipedia is talking about from the deph information comes, and here yes, it comes from some kind of triangularization that is processed in the brain. Of course, you can feel 3D without it, but then the information is faked by the brain and is not representative of reality.

so as an expert whats your theory of my seeing this in 3d?



hallucination

subtle chromostereopsis

subtle shade with distance with hints my brain into distance

that is actually such an alien perfect 3d you dont notice as you dont notice 3d in real life

As I said, I can believe that you feel that in 3D as a brain, yes, hallucination or fake 3D, extracted from other information ( I think is not difficult for any in this forum to realize your brain works in a extrange way ).
As you said shade/fog can contribute to depth perception, unless in space there is no fog but in nebulas, so that shade, if is there, is not related to depth.

But, even if I can asume the possibility that you feel 3d sensation looking a 2d photo where is no depth information available ( like fog or perspective ), I can´t in any way think that the depth information you think you are extracting from that photo is representative of reality, because that information simply is not there.

If you agree with this, nice. If you don´t there is extremely easy to prove you wrong. You can render two spheres with arbitrary different sizes, one closer to the camera and then you have to tell what one is closer. There is no way you can do that without pure casuality. Or even more easy. You can do this even in the real world. Pick two stars at night, guess wich one is closer, then compare it with astronomical data. You will found you wrong most of the times.
