Thread: The Fourth Dimension

Ew, I think this is becoming a bit convoluted...

That isn't a drawing

When I said drawing there I meant a 4D representation of a 4D object on a 2D surface in 3D space.

BUT

You can still represent 3 dimensions on a 2D surface.

And 4 and 5 and as many as you see fit.

Yes, but not in 3D space. Which happens to be the kind we live in :-/

Lost cause...

It's a pretty simple concept

I know it is.

I'm not saying you CAN draw a 4 dimensional object. I'm saying you can REPRESENT it.

Just like you can't draw a 3D object on a 2D plane. You can only represent it.

Well, not in 2D space, at least. It's all about the space the surface is in.

But drawing IS representing. So you can draw a 4D object on a 3D or a 2D surface. You can't comprehend the extra dimension, so the object you draw will always seem to be a 2D/3D object. Because of our spacial perception the drawn 4D object (Either in 2D or 3D) will look like a "complex" 3D object. I thought this was obvious. As for an actual 4D object being made, that's not possible.

I have a projection of a tesseract in my room now... made out of geomag.

It's really quite cool. I did it a bit different to the standard way (i.e. this thing) by giving it sides of equal length, to make it more realistic... it worked actually. You can see very clearly all 8 cells and how they have been warped in exactly the same way that the faces of a cube are warped when you draw it in 2D. I've also discovered that from the right angle it can be made to look like a cube drawn in 2D, which is interesting.

No, you CAN'T. How many times do I have to explain? It is IMPOSSIBLE to draw a 4D object in 3D space.

Uh I'll drop out now.

To be honest I don't think we should fight over silly things, it's an interesting topic when you don't get hung up about the details.

All I said was you can't draw a tesseract, and this erupts, so...
