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.
