wtf ...

I dont really get the point of 4-D lol, it are just two 3d objects ?

you need to view it crosseyed
it makes it look
stereoscopically 3d^^

Steroscopic 3D is with the use of two images of the same but taken from different distances..

Example of a 3D theatre camera:

[1]
---[2]

1 = camera 1
2 = camera 2

These two images are spit down the middle of a Steroscopic 3D TV, without the glasses on you can see the blur created due to the 2 images, then at a 200hz the glasses flicker within mere ms different shades of light so much faster than what our eyes can see, tricking our brains into thinking there is only one image on the screen thus bring depth into the image..

or one other way of explaining it is a pigeon. Pigeons have their eyes on the sides of their heads giving them no depth perception. If you see a pigeon walking they will move their heads back and forth, weird right but their eyes are not as sensitive as ours so the motion they are doing is the same method used as the one above. Giving them depth perception.

Also to answer your question of what the differences are. We can explain this by using SA:MP. the world of San Andreas is 3D. You have an X, Y and Z dimension. Giving it a total of 3 dimensions.

Say a square is only 2D because it will only have an X and a Y dimension. But turn it into a cube your get a Z dimension. 3D = Three Dimensions

4D is just another version of 3D with physical effects. Wikipedia Article on 4D(Film)

Also take this picture, you don't have to cross your eyes, just focus to the whole picture. It's 3D.


The things that are in 3d are the baby, the monster and a couple of things on the ground. This is a much slower method and not the nicest method to obtaining a 3D effect. Get two images, one a little further away from the first and make them into an animation where they two images switch between each other. To get things in 3D you make them not move at all. So the scenery around them seem to be more distant. But as said, not a clean method.

I thought 4D was when you could actually interact with the objects.

Just crossed my eyes on a ******* video, i got sick of how cool crossing your eyes on a doubled images can be!

it may be 6D

agreed^^

From a pure scientific perspective, 4D can not be seen by us. (Do we don't even know if a "fourth dimension" exists at all.)
So calling it 4D is just plain bullshit...
