2D -3D

How do we perceive reality - vision being our main sense.. we "see" a 3 dimensional world, as I type this.. I m seeing a room , chairs table TV, TV is far away, chair near me .. the room is slightly tapering showing perspective.. I feel the sense of space around me.. I "know" or rather  I "see" this space..
I see a flat picture on the TV screen..3D no depth. I see a flat 2D image on a magazine.
I feel 2D is a compromise of seeing and 3D is the "real" world..
but u know what?
Isnt 2D  how we acually see the world?what our eyes see is exactly what we see in a photograph right?  a 2D image.. and 3D - is fake! 3D is the simulation, 3D and the sense of space - this is the work of our brain.. its the modeling done by our brain to facilitate us to navigate in a 3D world,.

Brain takes this image and memory and does 1001 processing. ( need to read up on that) makes discrete 2D images into a continuous 3D movie/simulation/game!!
(havent read it.. but looks good ... this one.)

They say - brain uses the difference between the images from left and right eye to determine the depth of the world..  but does the vision that we see collapse into 2D if we close one eye? ;-) like this? no..
The model is made from memory.. I think it uses not only 2 angles but also shadow/light,perspective and what not  and also memory to build this 3D world. I think painters who create pictures know instinctively what parameters brain uses to create this depth..


Also this model is our limitation, if even tho we lived in a 3D world but our model was a 2D one, we would be stuck in it! :) and move like we were stuck between 2 glass sheets :) like flatland :)


Again it goes to show - everything is Maya - unreal! I know this,believe this but is it real for me?do I feel this? no! :-) how does the realisation of this take place??

I dont think our brain scans and creates this world everytime we see, like mpeg decoding.. it patches up only the changes.. and thats why sometimes we dont see the things we are searching for even if they are right in front of us, if we dont expect them there. our brain has decided that portion of the 3D world doesnot need refreshing - it couldnt have changed , so it shows us memory of that table.. when that bloody key was not on it :)
When people take hallucinogens they can see the room in front of them even with eyes closed! They can move around too!! offcourse the information is all there!! May be, to make us believe that it is not a projection but it is reality, brain switches off this projection when the new images stop coming i.e when we close our eyes, but  it is quite capable of continuing the show - even with eyes closed...like our dreams.we are quite capable of making our own landscapes...Imagination is one thing, this is total reality experience.. like reality but not!!! anyway I think astral projection and Out of body experiences are all this...Alternative states of consciousness.. I may have said before meditation/yoga is actually hacking our own brain.. enlightened person is the ultimate hacker.
