4D Tesseract 3D projection

[Tizohip]

uauuuuuuuu!!!is Awesomeeeeeeeeeeee

[Wowmaxy]

The 'shadow' below the object is not really a shadow from a point light source above the object projected down onto a plane, but simply a greyed object. That's why this presentation is unconvincing.

[Partyman908]

Bad ass

[meatwad260]

Abandon all hope. The unimaginable is now a reality.

[RMJ1984]

thats really wierd to think about, how the hell in what dimension can that cube have all it sides right angles. that is so weird xD

[diegocrusius]

I sorry, but what makes this object more special than a regular 3d cube? If you need to add the time element to apreciate it being 4d - rotating it in this case - wouldnt you turn a 3d cube into a 4d object by just adding the time element and rotating it too? I can't see this object being more than a complicated 3d object which moves through time.

I know theres this 'shadow of a 4d object' thing but that argument just tells that ANY 4d object is just a 3d object 'moving' throug time.

[TheLairOfRockwhales]

oh gosh i'm starting to understand this thing and what it looks like

phggfdds

[elbil100]

my brother is the guy that made this! its true just ask him. his name is mathias 

[Ysabetwordsmith]

I particularly admire the use of planar surfaces, reflection, and shadow.

[babyshamb1]

If you just put a glass/plastic cube inside a glass cube and attach the 8 corners with rods,isnt that the most acurate projection of a 4D object? just because its a projection dosnt mean its not a solid 3D object in our world. The animation just tries to show how a 4D entities would see a 4D object whilst moving. Really cool though.

[dochertyryan]

@babyshamb1 True, but the the 4D object wouldn't be able to move in the ana-kata direction.

[NutsandGuts]

If you can see "3D" on a 2D screen, why can't you see "4D" on a 3D screen?

[xxxxx123456789xxxxx1]

because we can imagine 3d objects far more easily than 4d objects. "2d people" probably can't imagine 3d objects, similar to us in the d world that cannot imagine 4d objects.

[Mozarteen]

@NutsandGuts

Because we don't have a 3D screen.

[NutsandGuts]

@Mozarteen I've seen some low res prototypes but it isn't impossible.(in fact a friend of mine built one)

[FluffyBunniesOnFire]

@NutsandGuts Because our eyes see 2D and our brains infer depth from the stereo image pair (depth perception is different from 3D vision, which we don't have). The end. We simply cannot see 4D.

[NutsandGuts]

@FluffyBunniesOnFire You mean we can't see "everything" but a 2D illusion our brain perceives as 3D?

[Tlove816tt]

@NutsandGuts yes. Our eyes do not actually see in three dimensions. think about it. Your eyes see three dimensional objects, but perceive them as two dimensional shapes. It's the reason you can draw a 3d object and make it look like it's 3d. But if you rotate the drawing, it doesn't move... you're seeing it from the same angle. The same way you can draw a 4d object in 3d space. But the drawing is only in 3d, so you'll only see it from the same angle, no matter how you rotate it, (though its 3d)

[dochertyryan]

@NutsandGuts Because a 3D screen doesn't exist.

[iamstoned4life]

Looks nice

[WildStar2002]

Nicely done!

[Alexandurs]

so how would be the shadow if it wasnt spinning?

[FluffyBunniesOnFire]

Looks really good!

[K2ACP]

@canadakim1 you should learn how to spell, before doing any reasearch

[hggh93]

dude you think you are winning this one because you told him he should learn to spell? what are you a 7-year old?

[GuiltyGearRockYou]

A 4D objecet in a 4D world throws a 3D shadow (or projection) and a 4D object in a 3D world is still moving

aaaaaaaaaight? =)

[JohnLeBlanc77]

hmm, so in this video are we assuming that light is from the 3rd dimension? Or would light come from many different places and not just from above?

[Mewpwnz]

Mmm a realistic tesseract, interesting.

[famboyantjoe]

you can represent a 4-d hypercube by colapsing a one spatial dimension of a  3-d hypercube to a 2-d hypercube. Then by rotate the 2-d cube you get back a time dimension.. The angular velocity is a function of time. All points on this rotating cube are convoluted. The front is the back, the top is the bottom

[CortlanT]

A 4d cube is all right angles, the Tesseract you made is really just the shadow.

[sbhk1]

watch this vid

watch?v=Y9KT4M7kiSw

in this vid you will see an explanation why what see is just the shadow

[CortlanT]

I know why it is a shadow, it is because a Tesseract has all right angles, like I said before.

[sbhk1]

I just added a comment with an explanation vid to your comment, so that other people that read ur will understand why. :)

[CortlanT]

Ok cool, because I am sick of al the videos of a "tesseract" when it is not.

[crazy650c]

You're thinking plane geometry. If the surface of the tesseract is spherical, then all angles can be 90 deg and yet appear not 'cause of the rotation. The shadow of a rotating object is deceptive. Try making a vid of a rotating object's shadow. You will see. A triangle on a sphere can have 90 deg on all 3 angles yet still be a triangle. Space is curved. Objects beyond 3D cannot be flat but must be curved. A 4D animation in 3D is similar to a shadow of a 3D object in 2D.

[Mrules4ever]

so how do we know what the shadow looks like if no one has never saw a tesseract before?

[juggliac]

@Mrules4ever all 4 dimensional research is mathematical and/or based on previous dimensions, so it's just relations that are common between dimensions.

[GuiltyGearRockYou]

thats right! BUT! he already wrote down 4D in 3D... so...

[mikepike25]

@CortlanT or a ............3D projection, a shadow is a a 2D projection of a 3D object.

[oterpoter]

language!

watchit ;)

m

[RUL1S88]

you retarded dickass, that's 4D tesseract and 2D projection!!

[stevenstreets3]

the shadow perspective is most helpful

[Drboomheadshot]

What's up with the spinning?

[MIDNAq1LINK]

We can only see up to the 3 dimensional shadow because we aren't 4 dimensional.

[DAILEYericCaryUSA]

Very great. Thanks.

[agedude44]

if you take a 3D glass cube, ex with some color, and shine some light throug it, the shadow on the ground resembles the 2D projection of the cube.

If you were a 2D person, what you would see is just the shadow, hence a 2 projection of a 3D object into your 2D world.

but a 2-d person couldnt see a 2-d shadow. they could only see a 1-d prespective (a line) of the 2-d shadow which is a projection of the 3-d object.

someone ought to make a 2-d video game using only depth and width 0.o

[IAmBrigUsername]

Why don't I have badass software like this?

[just2w4tch]

that's messin my head up man.

[Negentropy0O]

and 1d shadows make ?

[Negentropy0O]

i mean if there are a point in 1d dimention what shadow it will make? an 1d shadow ? or it will depends form the source of light

[pivotgurl]

they make 0d shadows. and 0d shadows make -1d shadows and so on and so on till you get to the negative infinite dimension. it goes the other way too only to the +infinite dimension. only there do you learn that everything has infinite dimensions. humans are just to stupid to SEE beyond 2D and PERCEIVE beyond 4D. it takes an acid trip to fully understand WTF i just explained...

[samedelsten1]

Ill go buy som now, then re-read your post.

Then Ill probably have a Tea-Party with Mr.T in an infinite dimension, and my eyes will totally fuck up.

Here I go...

JK ;)

[walikai]

whats the point of making tesseracts morph like that? proves nothing. a tesseract is simply a depiction of a 4d cube's shadow on the 3rd dimentional world. 4d shadows are 3d, jus as 3d shadows are 2d. i guess you could also say a 2d shadow is 1d.

[TiagoTiagoT]

that "morphing" is actually a rotation, just like how the 2d shadow of a rotating cube might "morph" into somthing similar to an hexagon depending on the way the cube is rotated

[walikai]

good point, but still, rotation = not necessary.

[mattlambrecht]

its cool looking. lol

[MIGUEL2005LIMA]

ALL IS IN 2D.

[begvend]

Hi, super video.

If verticality of frame is named Y axis and fourth dimension is named W axis, then the movement of tesseract is a rotation around of the normal vector to the YW plane.

[upupsteru]

oh SHIT!!! im almost understanding.

[oterpoter]

Excellent summarized ;)

mathias

[radiopassive]

so let's sum it up. this anim is the 2D projection of the 3D projection of a 4D cube :)

[BriDirt]

dude, that it called a tube. Sure it is made of cubes, but if you replace all of the cubes with a fabric or say rubber, it is possible to make it. you can see that something could pass right through the middle of it from top to bottom

[churchrvbrvb]

this is the only way for a human to visualize the tesseract, this is what the tesseract is but because we live in a 3d world we can not show a 4d object this is as close as we can get this means that no matter what we do we can not show at all the actual hypercube that is the tesseract

[ch33zer]

church is right. This is the "shadow" of a tesseract. In the same way that a 3d cube has a 2d shadow, a 4d hypercube (or tesseract) projects a 3d shadow. That is what is shown in the video. Watch the video by Carl Sagan for more.

[AdeonWriter]

Yes your monitor is 2D, but that doesn't change the fact that the MODEL he made was 3D information, he could have changed the camera angle and such. Yes, to you, behind the screen of the internet, everything is 2D on your screen.

[torchick163]

i like that model,its shiney ^^

[zedextreme8177]

My eyes have tesseracted!:P

[reki107]

TeChNiCaLlY That's a 2d projection of a 3d projection

[mattlambrecht]

or... 2d projection of a 3d (projectional) REPRESENTATION of a hypothetical 4d object.

[CkerCky]

both were 3d..

we cant see 4d

[oterpoter]

if you read what it says it says 3D PROJECTION!!

if you put a 3D object (ex made of glass) in front of light, what you see on the ground is a 2D preojection of a 3D shape

THIS is a 3D projection of a 4D shape

of course we cannot SEE 4D!!!

:)

but we can project it!

[reki107]

actually what we are seeing is a 2-d projection of a 3-d projection all the time! we cannot reach out and touch the projection with our hands and feel around it, and so it is two dimensional.

[brumanima]

this can be presented at our universe that i can touch it

[DitDevil]

Think like this. Lay flat on the floor on ur side. without moving up and down, u are technically a polygon looking in 2-d. If someone were in fourdimension they could look at what we look in 3-d as if it were lyding down on the floor. 4-d is not in our universe.We live in 3-d

[oterpoter]

since we are not able to draw, see etc in 4D, the tesseract is merely a PROJECTION of a 4D Cube. the "shadow" of the 4D cube (here projected into a 3D universe), is also a 2D projection of the 3D Projected 4D cube..

xMxlxeTx: if you take a 3D glass cube, ex with some color, and shine some light throug it, the shadow on the ground resembles the 2D projection of the cube.

If you were a 2D person, what you would see is just the shadow, hence a 2 projection of a 3D object into your 2D world.

[halomodder789]

woah woah woah if the 3 dimensions are height width and depth what is the fourth time or convolution or what?

[61219954]

its just the shadow in 3d is not the 4d model but god job :D

[xMcIceTx]

this is deffinitly not 4d lol its just a simplified ring -.-

[akuro123]

No, it isn't, it's a 3D projection of a 4d object

You just cannot see it because we live in a 3D world

[SnakeDragonFish]

Liked the vid.
