3D Cliffs Of Dover Pictures

yes showing the right image in movies can only work for one person

but in games there just one person

what johny lee does is match the fov of the game and the fov that the screen takes from your eyes

on this way however distance to the screen your always wacthing the "right" image perspective

that is NOT just 6dof its a WINDOW effect

the problem is that nobody sems to understand that but a very few

It IS a 6dof with the right camera movement to simulate a window. In fact I think it only follow displacement, and not rotation... whatever.
I have lot of years of experience in 3D and sterescopy and I had tryed that myself. I know pretty well what it does, and while interesting it has nothing related to stereoscopy.


In games there is only one person, BUT the screen size still lacks the fitting to the real thing scale, and that is a requirement to have the realistic sensation.
Again, when real full field of view stereo glasses arrive, then we are going to have amazing experiences in videogames and movies with stereo. Before that... unless you have a surface to stereo project in big size with a nice tracking... we don´t.

I mean, you could try to simulate a realistic projecton in the screen size, like if the screen were a real window, but this has several main problems. First is the edges of the image where the ilusion would break, using trakIr scaled rotation would kill the effect also. But the more important, you would need to play with a zoom that would made the game completely unplayable. So if you want stereo games in a screen today, you have to play like if objects were small models and not real size items.

wtach 3:37 of the johny lee video and youll see how this system contrary to 6dof is like a window since IT CHANGES FOV with position

this other video reflects two things:

1) how the johny lee system is old and widely used in media if you think about it, game design is light years away from tv media

2) for what i know bin laden could not be death, 911 could have been a green screen thing, in fact even nyc could be a green screen thing

raaaid... what was your point?. I lost the track of the conversation.
That things can be faked in media? sure.

But I though we were talking about how real a 3D stereo can be and if you could see 3D stereo in 2D photographs. I don´t know were are you going now.

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
