I don't know about anyone else here, but I've always found the presentation of 4D geometric objects really bizarre and perplexing. I mean, you can go up to a blackboard and draw a 4D cube as 16 points and 16 lines, and it looks like a cube within a cube, but how the hell would you manipulate it.

http://mrl.nyu.edu/~perlin/demox/Hyper.html - little Java applet I stumbled on which lets you rotate through normal 3D as well as 4D. Really mind-warping to try and understand how it works.

Great way to kill 5 minutes anyway.

It seems like changing it's shape. Farther = smaller.

Otherwise it looks like ordinary 3D object.

I think its not too much of a trip for people who havn't thought about 4d too much.


But yeah, this is trippy as hell.

Try, "cross" or "uncross". My sister said it was... odd to say the very least.

If you got blue-red glasses, there's anaglyph too.

These are just 3D objects with illusion tricks, trying to make people believe it's 4D.

technically since it's impossible to have real 4D objects in a 3D universe

The interpretation in a 3D world from what I can see is more like a constrained translation.

I think it's easier to think about actually if you consider the similar relationship between 1D/2D cubes (line and square), and 2D/3D cubes (square and cube). A square is basicly 2 identical lines connected with 2 translational lines, and a cube is basicly 2 identical squares connected with 4 translational lines. Looking at a 3D cube head on as a wireframe is basicly a square within a square, which rotates in and out in funny ways when only considered as a 2D drawing.

Now I want to play with OpenGL again.

Wait, RII, this isn't NEW at all.

There's gaming consoles that had 4d capabilites since... 94 or something. Namely: The neo-geo.

i wonder how messed up 3D objects would look in a 4D universe
