2D and 3D
I saw this question on another site and I thought it was pretty good, so here goes...
What do you think a 2D world looks like to a 2D person? What do you think a 3D world looks like to a 2D person? |
impossible for a 2d person to see 3d as they would only see in a straight virtually atom thin line.
two birds with one stone. Huzzah! |
read Flatland.
|
I've read that...wierd, wierd book.
|
Well, a 2d person wouldn't be able to comprehend depth, if they saw something 3d. And to a 2d person, 2d would be normal, but it would be 2d....
I'm sorry, I have no idea. That's an interesting question. So what's this Flatland? |

hmm.. well i guess the 2d world would look 2d... considering everything looks like its on the same plane in 2d.. but your eyes give you 3d perception. the two view points create depth... but since your eyes would be flat.. i guess you would have a certain type of funnel vision... but still the 2d guy could give depth to the 2d world with the ability to create depth with his eyes..
and the second question.. would basically have the same answer.. |
As soon as I saw the topic I thought "Flatland"
|
If you think about it, 2D objects are 3D, since everything has a width, or it cant exsist. No matter what medium. Pencil on paper. The graphite is 3d, and its markings are 3d, though somewhat infestismal. A piece of paper has width, a film reel has width. 2D is merely a human illusion.
(based on 3 minutes of thought using common logic) |
what about 4th and 5th dimensions and so on?
|
Isn't the 4th deminsion time? or am I just insane.

Thats what i said in my second post :x

ack, sry feuerg, accidentally skipped over your post =(
|
the above post is by me, and to add to it (so its not "off topic") if 2-d worlds do exist i guess volume in them doesn't exist at all, there must only be surface area. way too wierd to imagine what it'd be like
|
dont think of this as a place(2-d world).. think of it as a imaginary world.. dont try to add logic to your eyes need depth to work.. or anothing like that.. just assume that they would work without turning.. so it would be like looking straight ahead and to look anywhere you would have to turn your whole body....but.. this would rally take too long to explain what the world would be like.. so.. if you can't imagine it.. go watch some more barney..

Keep in mind that I have not read the other responses yet because I am a lazy bastard.
Buttt... I think it really depends on what 2 dimensions you are talking about. For instance lets say our 2D person has Y and X (height and width). They could therefore see in 3D even though they are 2D because their eyes would both be X units apart. So a 3D world would look normal to a 2D person of that type. If the person was Y and Z and had no width, they would either see in 2 dimensions or see nothing at all because there is no width for the eyes. Again, for the 2d person in the 2d world it depends on the orientation of the 2D world. It should look 2D because they exist in the same realm but the problem here is that this cannot exist in the first place. Owell.. just my 2 cents in 1 minute. Cheers, Synthlight |
isnt this a 4d image?
|
no.. its 2d.. all pictures are 2d.. and if you made that in real life(if you could).. it would be 3d..
|
Heres that page. Shows java animations of 4D stuff. Manily under the HyperDimension catagory, though there are other stuff.
