Imagine playing catch with a 4D ball but then your friend (who sucks) throws the ball so badly, it ends up along the w-axis and your cool ball is lost forever. Thanks Brad
Since your friend is 3D, he should only be able to knock it along the 3rd dimension so long as the ball's cross section in our dimension is the exact center of the hyperball.

Because it's literally not possible to understand since we biologically cannot function imagining a space like that. We can only conceptualize it based on math and create a simulation of what it would look like, but we cannot imagine another direction that is perpendicular to all our current 3D axes of x y and z.
@@karlpatrick1257 i bet we can. Our brain is so flexible that if we woud play with 4 dimentions for a while, in vr or something, out brain woud be able to understang the pattern and succesfully navigate in 4d world like it does in 3d.
I think what could improve this even further is to provide a simultaneious projection of multiple 3D slices of 4D objects. Like, split your 16:9 screen to 20 squares, and in each square traverse set the value for 4th dimension from a range. All 20 squares depict same scene, but at different 4D depths. Therefore when a cube "disaapears into 4th dimension" in square 1, it should be popping up in square 17 for example. Watching your interactions this way could provide invaluable intuition
I always thought 4th dimension is time but it seems he made 4th dimension a place. If this guy manage to program it he didn't manage to explain where the sides of the cube goes. Where does it end up ? In 4th dimension he says but if it is not time what is the forth dimension?
It's a 4th spatial axis: you can't imagine it and neither can I, our brains aren't capable of it. We can deal with left-right (x), up-down (y), and forward-backward (z). The objects in this video are, as well as moving in those three spatial axes, also moving through a fourth - But just like the imaginary being on a 2-dimensional plane can't see or imagine a 3rd dimension, we 3-dimensional beings can't see or imagine a 4th. You can describe it mathematically, but you can't display it in a way that makes sense to humans (yet!)
So how did he program it? z-axis moves away from us into the depth. The 4th axis he programed and controlled with a lever to right. I'm fine not seeing it physicaly but explained, yes please.
I’ve been to one of those “4d” movie theaters which are named so stupidly because ADDING A FOG MACHINE TO THE MOVIE DOES NOT ADD A WHOLE NOTHER FREAKING DIMENSION TO THE UNIVERSE
4D in terms of movies usually means adding an element that makes you feel part of the movies world, adding smells, moving seats, soon we might have virtual reality movies
Speaking of the 1st dimension, I have actually thought of a 1D game. Yes. Sure, my thoughts are to keep the GUI 2D, but basically it's an 8 bit-ish style game, where you have a line of pixels and the color of the pixel indicates what is there. A black pixel might be a pit that you have to dash across, a brown or yellow pixel is an enemy you attack, and there are ground pixels and a player pixel.
@@Thenameisbond1 I think of it like, we actually see 2D but we interpret it as a 3D space. 2D beings would see a 1D line that they interpret as a 2D space. So only 4D beings would truly see in 3D

I usually imagine it as some kind of slider you use in some simulator to change mountain heights. For example, try to imagine a mountain, but it's getting higher and lower when you move along the w-axis. The mountain we see would be our "slice" of mountain. So if we combine all the versions of the mountain, we have a 4d image. But this is just something I made up when pulling an all nighter so I don't know about the accuracy
Lol. Though if I’m correct (I’m not 100% sure I am) the 4th dimension’s version of length/width/height is “trength.” I read that somewhere but, again, I am not sure if it is correct.
*this is the best description of 4d I have ever come across on the Internet. And I have spent quite a long time trying to understand this, and falling down the wormhole of the Internet.* thank you
SRS Secret Rogue Society thats kinda an improbable theory considering spatial dimensions beyond 3 only exist in math, or in theory as suggested by string theory. that said, these different higher dimensional objects or spacetimes dont interact with lower dimensional objects or spacetimes. so ur really just throwing out a whimsical idea that doesnt mean much. its basically impossible by the definition of dimensions for a lower dimensional object to leave its plane for a higher dimensional one. for example, if a square with measurements 1x1 were to leave its two dimensional plane and enter a three dimensional plane, it would have to become a cube with dimensions 1x1x0. but then it isnt two dimensional anymore it now has a third dimension which has no width. but still three dimensional. this is also why it is impossible for us three-dimensional beings to see into four spatial dimensions at one time. because we are bound by three dimensions and always will be.
Hezrayta Bast Brandão this is something incomprehensible to the human mind, this feeling is when it’s compared to something you can understand, but you know behind the 4D plane, there’s something going on that you simply can’t express, it’s physically and mentally impossible, the only way this game was possible to make was some fucking amazing coding, and by god would I love to see it.

Santiago I don't see how it's shitty? Carl Sagan described it in a very similar way, the only difference is you can actually play with the 4 dimensional shapes, which is pretty cool.

"A 2D character can only see 2 dimensions" Actually, from what I remember about dimensions is that from your little stick figure's POV, they'd only see 1 dimension, up and down. 3D characters, like us, can only see in 2D but we live in a 3D world. A 4th dimensional being could theoretically see in 3D (all sides of an object at once) while living in a 4D world, by this logic.
That's because we never see a 4d in our lifetime, so it's nearly impossible to conceive what it looks like. Just like the colors outside our visible spectrum and it's impossible to imagine the unseen colors.

This explains exactly why there is no 4th physical dimension in our world otherwise it would become usual to see things dissapear or come from nowhere when they intersect with our reality. in the dynamic world we live in, don't tell me this happens and no one saw nothing.
thats not how it works, this game isn't a true representation of 4d, it's impossible to make one this is just a projection of 4d objects onto a 3d space, which is why all the disappearing and reappearing happens if you could actually see what living in a 4d universe would look like then none of that would happen, but of course that's impossible because ours is only 3d, so a representation like this is the best thing we have
i think we aren't capable of comprehending 4d life. just like how there's no life in 2d, so there isn't any 2d creature to comprehend our existence. but then again we exist. if there's 4d life it's something else altogether our 3d mind can never understand. but then again im projecting my 3d experience on 4d beings
@@2fifty533 right, but we, only being able to percieve things in 3d, would experience objects disappearing if there truly was a 4th spacial dimension. Because to us, all we would see would be the projections of the 4d objects onto 3d space. The fact that we're not seeing that means that a 4th spacial dimension probably doesn't exist
Crazy Productions Like how 3D objects were out of view to the 2 dimensional being when they passed the "slice, an object passing into the 4th dimension is invisible to us because it is entering a dimension we do not exist in. We could see the 3D objects because we exist in that dimension.
Both the premise and interpretation are entirely correct. It's simple math--the same math which defines all n dimensions. You can create a 3D object by taking 2D z-stacks, and a 4D object by taking 3D w-stacks. And no, time is not the fourth dimension. Time is not a spacial dimension at all, and it applies the same to all spacial dimensions no matter how many.
In my mind I was like [I'M SUPPOSED TO BE IN TOTAL CONTROL. THIS IS A KID'S TOY. I CAN'T EVEN BEGIN TO UNDERSTAND THE PLACE WHERE THIS ISN'T WORKING. THIS IS SIMPLE AND I CAN'T GET IT] I wasn't even the one moving the hypercube. I was just watching a video.
as other people have said, this is actually one of the best videos i've seen on the topic. way easier to understand when you realize that you can't actually "see/visualize" the 4th dimension no matter how hard you try. But you CAN conceptualize knowing that the cube isn't actually disappearing or changing shape, just the part of it you can't see is extended into the W-Axis and the new part that you can see came from the W-Axis into your point of view (probably at W=0, where our 3d plane exists). This is way more interesting and makes a whole lot more sense too when you see them as a solid. All the other videos make the tesseract etc with wireframes which seems like it would helpful but actually makes it more confusing.
I have no clue why, but watching these hyper-objects seemingly change shape as they bounce about the fourth dimension gives off the vibes to me of eating Smarties. Something about it just reminds me of the nice crunch of biting through them to have the sugary dust release itself upon your mouth feels a lot like these warps.
@@5thnovemberscrivener634 I've always had the theory that "Real" ghosts are likely 4th dimensional imprints of consciousness that dead people leave behind. It's like burning an image onto a plasma tv by leaving it on too long. There's an imposition set upon space which is unchanging through time because it is fixed on a certain w coordinate different from our own and so we don't get shit like that and see it as a ghost. It would explain why ghosts never leave the same place or the same thing. They literally live in a pocket of time.
This is interesting. Usually, 4D is explained by shadowing 4D objects to get 3D lookalikes. Instead, this is made by taking slices of the 4D space and viewing it in 3D.
We only see in 2 dimensions. An object’s dimensions outside of two dimensions (LxW) are seen as perception which we call distance or depth. We travel in that third dimension (go there, look behind it!) to view the depth/distance dimension. The shape of the object changes as we enter that dimension of distance, seeing the hidden parts of various phenomena...

no 2d guy feels worse he just see a line getting bigger and small he dose not see the shapes. its 2d he cant see it from the front like we do in the video he would just see the side.
This is such an excellent tool and demonstration; I just have one quip. You keep saying "it has moved into the fourth dimension" This isn't correct language. This makes it sound like the dimension is external to the other 3 when it is equally orthogonal. Better phrasing would be to say the shape has moved along the 4th axis (and out of sight if explanation is need). Again, great demo. Minor quip.
I knew it! I always thought that in the fourth dimension you'd need a fourth axis, and I didn't even need to look that up! prob just being full of myself, but still!
@@biopticbl00d It works like any other dimention greater than 1, any aditional axis is orthogonal to all previous axis. we have to imagine it above 3, a 1D character sees a point projection of their reality which is a 0 thickness and width line, a 2D character sees a line projection of their reality which is a 0 thickness plane, a 3D character sees a 2D projection of their reality which is a 3D volume and so on higher.
Does anybody else have dreams like this where they can see the box, all six sides of the box, both from the inside and outside the box, as well as everything inside the box, as well as inside and outside of those objects inside the box, and all at the same time? It's difficult to describe in language of 3D terminology, but that's all I have so I hope it makes sense.
Pretty good, although the toys aren't knocked to the 4th dimension because they already were in the 4th dimension, they just moved out of our " 3d viewing area"
They are in the sense that they moved along the 4th dimension which can't be observed in any of the other three dimensions. They moved to a place in the 4th dimension that we can't see. It's not meant to be literal. It's just a way of saying that the object has moved to a place that we can't see, along the 4th dimension.
I once watched a bug stuck in a 1D world with periodic boundary conditions (a circle). It was walking on the edge rougly circlur upper edge of a basket. It could move forward and back, turn around, but wouldn't go down either side as they were too steep. Very interesting to watch :D
@@L3010 In defence of C4D their whole thing is that "The forth dimension is time", with it being an animation software. In Miegakure's video and game, they state that they view the forth dimension as a simultaneous state, so some people view it differently to others. I'm only defending it because its my favourite software and I think it's leagues ahead of smell-o-vision :P
You say, that for 2d person it's not possible to see 3d objects, but as we can see 3d objects can be visualised on 2d screen thanks to tricks like shading - imitating perspective. Wouldn't it be possible to visualise 4d objects the same way - by shading, or showing wireframes of object in next iterations of 4th coordinate? I'd love to see that and would be very grateful if you could show it to us!
I was thinking just this as I watched. Another trick might be to utilize VR. Show 3D in 2D planes, but have a 3rd dimension of planes to represent the 4th dimension.
For an actual 2D being to be able to see that projection entirely, it would have to be able to see "inside" the 2d image that is created. Same for us, we would need to be able to see inside objects. Although it would probably look a bit messy, I guess we could use a transparent material to represent it. It would be an interesting thing to try
Tobiasz B - The computer graphics and mathematical term for what you are referring to is called “projection”. The term “slicing” refers to what is done in Miegakure and 4D Toys, in that you are literally taking an (n-1)-dimensional slice of the source object along a plane (in the case of 3D to 2D) or volume (in the case of 4D to 3D) or hypervolume (in the case of higher dimensional slicing). That much is intuitive. The way to think intuitively about what projection refers to is as though it’s a shadow, and actually you don’t need a computer to do it. Just hold a box up near a wall sometime and observe how the cuboid distorts into something weird on the wall if you think of yourself living in that 2-D space, with the line segments growing and shrinking for no apparent reasons and all the right angles bent out of shape. That’s the same thing. Or consider Enceladus’s shadow from the Sun on the cloud layers of Jupiter if you want to consider a spherical example. Same thing. Then you have the choice of what projection transform you‘d like to use (with perspective and isometric projections being most common), and whether shapes should be solid or semi-transparent or merely wireframe as shading choices are significant to the reality your portraying. This would be an addition to 4D Toys I’d really like to see… a button which would be able to switch you from a sliced to a projected view of the space. However, I would say that might be a lot of effort as it would rely on a completely different rendering support code and such a capability wouldn’t be appropriate for the Miegakure game (it would make it too easy to spot things nearby which were temporarily out of your view because of your position and orientation). In any case… great question. Wikipedia has a great entry cataloging a variety of such spatial transformations (collect ’em all in your graphics libraries!): en.wikipedia.org/wiki/Graphical_projection
Instead of taking 3D slices of your 4D toybox, you could wire-frame the shapes and build a virtual 4D camera that takes 3D photos. Then we could see all 16 corners and 32 edges of a tesseract at the same time. If a smaller tesseract passes inside a larger one, it's really just farther from the camera in the same 4D direction. With enough computing power you could do shading and ray-tracing in 4D, but a 1000x1000x1000 output image would contain a billion voxels and be very hard to view.
This is absolutely the best visualization of 4D I have ever seen. I already understood the concept but seeing how the toys changed so dynamically made some click in my mind. Thank you thank you!
I love it how ABSOLUTELY NOBODY can understand what is going on or what the 3d cube looks like, as four-dimensional life can see an entire 3d plane, however our vision is 2D
Why? We’re not supposed to know what 4d looks like. Similar to how a 2d plane (or piece of paper) is a SLICE of a 3d object. A 3d object is basically PART of a 4d object.
"I knocked over this pile, and some of the cubes fell into the fourth dimension, so I can't see them anymore" Never before has anyone said something so cool, so casually.
I wouldn't say "it moves into the 3rd dimension" or "it moves into the 4th dimension" because they are already in there .. It moves within it not into it ..
For a 2D being there is no third dimension. Because we see their entire world (we're 3D beings) doesn't mean that 2D beings have a third dimension. The same applies to forth dimension so his wording is right.
@@shayanmoosavi9139 For the 2D being there was no 3D dimension, but we could see there was and that objects were just moving through it and not in and out of it.
I think the best way of putting it would be to say that it moves out of our current 3D slice of the 4th dimension. (The same way that the 3D objects were moving out of the 2D character's 2D slice of the 3rd dimension.)
4:34 this is disturbing, imagine “4D beings” creating a portal to our “3D world”. They could rip our organs, muscle, and bones out of our skin without dropping a single blood drop.
That might not be possible, because we 3 dimensional beings are bound to our respective planes. Since 4D beings aren’t bound to us, we might be unable to be harmed by them because they might have no choice but push our world around in the fourth dimension when they try to interact with it. Like if there was a two dimensional universe in our universe, we might not be able to stick our hands into it, because it has less dimensions than our hand, so we’d just push it through the third spatial dimension instead. However this means they’d be able to harm us by just ripping our universe apart which is way worse.
Some mistakes: a 2d character can only see in 1d, we have two eyes that make an illusion of 3d,but we actually see only plane views of a 3d shadow of 4d objects.
Yeah. 2D beings would actually see an object growing taller on a single axis instead of it expanding. So maybe we’re the ones who would see a shape expanding, and from everyone else’s POV, their 2D vision would see the 4-D object changing and growing in different ways.
finally, the type of game I have always wanted. I would try making this myself if I was better at programming. Another 4-dimensional game I'd really like to try would be a fps or similar, exploring a doom-like hell level, but there are obstacles you can't go around in 3d so you have to move "heavenwards" to get around. There would be a continuum of 3d layers between "heaven" and "hell", with the level design being gradually morphed from one extreme to the other
There's no distinction between the third and fourth dimension to a 2d guy. Anything that moved in one direction would be indistinguishable from something that moved in the other. It's merely a plane of travel that is skew from his plane.
Have you played around with 4D ray-casting? It is how 3D objects are rendered on a 2D screen. (with 3D ray-casting) You basically have point from with a bunch of rays(lines) that go through a rectangle. Each pixel on the screen gets the color the ray, that goes trough the rectangle at that position, hits first. (the rectangle is mapped to the screen). By moving the rectangle relative to the point you zoom (moving it closer/further) and rotate (moving it on a sphere) and by moving them both (but not relative to each other) you move the camera. (actually it's not a rectangle but a part of the surface of a sphere but that doesn't really mater here) You could do a similar thing by moving around a cuboid in the 4th dimension. And mapping it to pixels in a VR world. (again it's actually the surface of a hyper-sphere) Or you could try to go down 2 dimensions (in 3D it's moving around a line, in 4D a rectangle) (the line is a segment of 1 of the circles on the surface of the sphere, the rectangle is a segment of one of the spheres on the surface of a hyper-sphere) This should contain more information that just showing 1 3D slice and ray-casting that to 2D. It should also look less weird (because objects actually hit the ground ect ( for a 3D being it's already confusing if you just see a slice of a 3d world but not confusing to see a ray-casted version). So it could be less confusing) Also I want to see a Klein Bottle in your 4D toy box.
Interesting idea, but you would have to project the voxel structure you get onto a 2D screen. I think I'll experiment with that. (the problem that arises is the following: if your scene is full enough, most of those voxels won't be transparent. So you can't do the normal projections, but have to do something else, even though that would break the symmetry that would arise: a 3D shape would still look normal, as long as it is rotated correctly)
@@Mreoewwmrow In fact they would see ALL points of 3D space as just a single line, or a string, they would need some kind of 4D viewing device that can show 3D (the way we have screens to see 2D pictures) to get a slice of the string, which would appear to them as a VR world fully 3D (not the way we see the world which is just 2D pictures with a framerate as fast as our brains can process) They would see 3D immersive still images as fast as their brains could process
@Stale Bagelz yep, it's more like 2d beings would see a 'line', but just conceptually. This line only has one dimension so it can't even be visualised as a line you could draw.
Imagen you're in your bedroom and this floating sphere just comes out of nowhere and starts randomly growing, shrinking, and moving... then you realize that the sphere is controlled by a 4 dimensional baby
To me, this is absolutely fascinating, but it is also very difficult to comprehend. For what I gathered, after watching other videos on the matter as well, one can see the 4th dimensions as a place where an object has all of its possible shapes stored/represented in. A 4D sphere might have any diameter variation between a minimum and a maximum diameter.Inside the objects is a collection of vertices and the many ways this vertices are connected to each other is stored in the 4th dimension. By moving back and forth thru the dimension, we can visualize each of said "ways of connecting vertices", and thus the various possible shapes.
@ryan7351 ryan7351 well think of the 2D world 3D object example in this video. It was probably not extremely difficult for you to get your head around how and why stuff behaves like it does there. A 4D being should equally be able to understand what's happening a lot more intuitively just seeing the 3D slice of a 4D object.
I enjoyed this video, but I do have one issue that kept bugging me throughout the entire thing. Whenever an object "disappeared", you said it "moved into the 4th dimension". They're all already in the 4th dimension, they're just moving along the 4th axis, which we can't visualize. Just a note, otherwise, great video, really entertaining and a pretty comprehensible explanation of an extremely complicated concept.

I don't blame u, it's literally impossible to understand it. our brains can't comprehend it

Because it's literally not possible to understand since we biologically cannot function imagining a space like that. We can only conceptualize it based on math and create a simulation of what it would look like, but we cannot imagine another direction that is perpendicular to all our current 3D axes of x y and z.

@@cycrothelargeplanet Imagine if we finally found that n-dimensional basket
I think what could improve this even further is to provide a simultaneious projection of multiple 3D slices of 4D objects. Like, split your 16:9 screen to 20 squares, and in each square traverse set the value for 4th dimension from a range. All 20 squares depict same scene, but at different 4D depths. Therefore when a cube "disaapears into 4th dimension" in square 1, it should be popping up in square 17 for example. Watching your interactions this way could provide invaluable intuition
Anyone else really irritated by lack of ability to see 4D?
Lorcan Yes. It would make complex analysis a much more interesting field.
Then we'd just complain about not being able to see 5D.
I always thought 4th dimension is time but it seems he made 4th dimension a place. If this guy manage to program it he didn't manage to explain where the sides of the cube goes. Where does it end up ? In 4th dimension he says but if it is not time what is the forth dimension?
It's a 4th spatial axis: you can't imagine it and neither can I, our brains aren't capable of it. We can deal with left-right (x), up-down (y), and forward-backward (z). The objects in this video are, as well as moving in those three spatial axes, also moving through a fourth - But just like the imaginary being on a 2-dimensional plane can't see or imagine a 3rd dimension, we 3-dimensional beings can't see or imagine a 4th. You can describe it mathematically, but you can't display it in a way that makes sense to humans (yet!)
So how did he program it? z-axis moves away from us into the depth. The 4th axis he programed and controlled with a lever to right. I'm fine not seeing it physicaly but explained, yes please.
I’ve been to one of those “4d” movie theaters which are named so stupidly because ADDING A FOG MACHINE TO THE MOVIE DOES NOT ADD A WHOLE NOTHER FREAKING DIMENSION TO THE UNIVERSE
Don't forget the bubbles
4D in terms of movies usually means adding an element that makes you feel part of the movies world, adding smells, moving seats, soon we might have virtual reality movies
There's a "7d" movie theater in my town and... There is just a normal movie with air freshener and water hose.

Speaking of the 1st dimension, I have actually thought of a 1D game. Yes. Sure, my thoughts are to keep the GUI 2D, but basically it's an 8 bit-ish style game, where you have a line of pixels and the color of the pixel indicates what is there. A black pixel might be a pit that you have to dash across, a brown or yellow pixel is an enemy you attack, and there are ground pixels and a player pixel.

I usually imagine it as some kind of slider you use in some simulator to change mountain heights.
For example, try to imagine a mountain, but it's getting higher and lower when you move along the w-axis.
The mountain we see would be our "slice" of mountain.
So if we combine all the versions of the mountain, we have a 4d image.

Cassandra Bankson isn't this basically show how wormhole would work in 3d, it knocks thing into higher dimension.
SRS Secret Rogue Society thats kinda an improbable theory considering spatial dimensions beyond 3 only exist in math, or in theory as suggested by string theory. that said, these different higher dimensional objects or spacetimes dont interact with lower dimensional objects or spacetimes. so ur really just throwing out a whimsical idea that doesnt mean much. its basically impossible by the definition of dimensions for a lower dimensional object to leave its plane for a higher dimensional one. for example, if a square with measurements 1x1 were to leave its two dimensional plane and enter a three dimensional plane, it would have to become a cube with dimensions 1x1x0. but then it isnt two dimensional anymore it now has a third dimension which has no width. but still three dimensional. this is also why it is impossible for us three-dimensional beings to see into four spatial dimensions at one time. because we are bound by three dimensions and always will be.

Santiago I don't see how it's shitty? Carl Sagan described it in a very similar way, the only difference is you can actually play with the 4 dimensional shapes, which is pretty cool.
So far this is the absolute best video I have seen at explaining what a 4D object would look like to us.
I have had struggles with the 4th dimension to, I lost my entire school project because it hit a hypercube and made a weird bounce into the 4th dimension.
that would be like a 2d square getting bounced upwards into the 3rd dimension by a cube (and only being a square, and not secretly a cube)
So, a better term would be that it "fell" through the fourth dimension.
That's why dude, never play with a Tesseract
"A 2D character can only see 2 dimensions" Actually, from what I remember about dimensions is that from your little stick figure's POV, they'd only see 1 dimension, up and down. 3D characters, like us, can only see in 2D but we live in a 3D world. A 4th dimensional being could theoretically see in 3D (all sides of an object at once) while living in a 4D world, by this logic.
Underrated comments!
This is correct.
Exactly. We see 2D because we can't see depth - we can only understand it because of how small an object appears and how it casts shadows.
@@the_otter5936 having two eyes helps with this aswell but each eye on it's own sees in 2D.

there's a reason for that
I don't think a single person in earth can comprehend, it's actually impossible since we are 3d beings

This explains exactly why there is no 4th physical dimension in our world otherwise it would become usual to see things dissapear or come from nowhere when they intersect with our reality. in the dynamic world we live in, don't tell me this happens and no one saw nothing.
thats not how it works, this game isn't a true representation of 4d, it's impossible to make one
this is just a projection of 4d objects onto a 3d space, which is why all the disappearing and reappearing happens
if you could actually see what living in a 4d universe would look like then none of that would happen, but of course that's impossible because ours is only 3d, so a representation like this is the best thing we have

@@2fifty533 right, but we, only being able to percieve things in 3d, would experience objects disappearing if there truly was a 4th spacial dimension. Because to us, all we would see would be the projections of the 4d objects onto 3d space.

Crazy Productions Like how 3D objects were out of view to the 2 dimensional being when they passed the "slice, an object passing into the 4th dimension is invisible to us because it is entering a dimension we do not exist in. We could see the 3D objects because we exist in that dimension.
Crazy Productions it's sounds like a jojos one liner
it shouldnt. both the premise and the interpretation are entirely wrong..
Both the premise and interpretation are entirely correct. It's simple math--the same math which defines all n dimensions. You can create a 3D object by taking 2D z-stacks, and a 4D object by taking 3D w-stacks.
And no, time is not the fourth dimension. Time is not a spacial dimension at all, and it applies the same to all spacial dimensions no matter how many.
A better way to phrase might be that you are getting knocked ALONG the fourth dimension.

@JBryan314 Nah, the bull's hypercube is, not yours.
as other people have said, this is actually one of the best videos i've seen on the topic. way easier to understand when you realize that you can't actually "see/visualize" the 4th dimension no matter how hard you try. But you CAN conceptualize knowing that the cube isn't actually disappearing or changing shape, just the part of it you can't see is extended into the W-Axis and the new part that you can see came from the W-Axis into your point of view (probably at W=0, where our 3d plane exists). This is way more interesting and makes a whole lot more sense too when you see them as a solid. All the other videos make the tesseract etc with wireframes which seems like it would helpful but actually makes it more confusing.
Thanks for the explanation, Ariana Grande!

Litterly no one has explained it like that holy fuck this changes everything
Probably because shadowning is closer to our experience: We don't see 3d either, we see 2d shadows of 3d objects
We only see in 2 dimensions. An object’s dimensions outside of two dimensions (LxW) are seen as perception which we call distance or depth. We travel in that third dimension (go there, look behind it!) to view the depth/distance dimension. The shape of the object changes as we enter that dimension of distance, seeing the hidden parts of various phenomena...

This is such an excellent tool and demonstration; I just have one quip. You keep saying "it has moved into the fourth dimension" This isn't correct language. This makes it sound like the dimension is external to the other 3 when it is equally orthogonal. Better phrasing would be to say the shape has moved along the 4th axis (and out of sight if explanation is need).
Again, great demo. Minor quip.

I once watched a bug stuck in a 1D world with periodic boundary conditions (a circle). It was walking on the edge rougly circlur upper edge of a basket. It could move forward and back, turn around, but wouldn't go down either side as they were too steep. Very interesting to watch :D
I hate when movies say they’re “4D” because they have smell-o-vision or something

@@L3010 In defence of C4D their whole thing is that "The forth dimension is time", with it being an animation software. In Miegakure's video and game, they state that they view the forth dimension as a simultaneous
state, so some people view it differently to others.
I'm only defending it because its my favourite software and I think it's leagues ahead of smell-o-vision :P
And especcialy 5 or 6 d
Actual there is a way to make a fourth dimension in C4d@@L3010 just you see it in a 3d world :)
You say, that for 2d person it's not possible to see 3d objects, but as we can see 3d objects can be visualised on 2d screen thanks to tricks like shading - imitating perspective. Wouldn't it be possible to visualise 4d objects the same way - by shading, or showing wireframes of object in next iterations of 4th coordinate? I'd love to see that and would be very grateful if you could show it to us!
Greeeeat question, sir. I will love to know that, too
I was thinking just this as I watched. Another trick might be to utilize VR. Show 3D in 2D planes, but have a 3rd dimension of planes to represent the 4th dimension.
For an actual 2D being to be able to see that projection entirely, it would have to be able to see "inside" the 2d image that is created. Same for us, we would need to be able to see inside objects. Although it would probably look a bit messy, I guess we could use a transparent material to represent it. It would be an interesting thing to try
Tobiasz B - The computer graphics and mathematical term for what you are referring to is called “projection”. The term “slicing” refers to what is done in Miegakure and 4D Toys, in that you are literally taking an (n-1)-dimensional slice of the source object along a plane (in the case of 3D to 2D) or volume (in the case of 4D to 3D) or hypervolume (in the case of higher dimensional slicing). That much is intuitive.
The way to think intuitively about what projection refers to is as though it’s a shadow, and actually you don’t need a computer to do it. Just hold a box up near a wall sometime and observe how the cuboid distorts into something weird on the wall if you think of yourself living in that 2-D space, with the line segments growing and shrinking for no apparent reasons and all the right angles bent out of shape. That’s the same thing. Or consider Enceladus’s shadow from the Sun on the cloud layers of Jupiter if you want to consider a spherical example. Same thing. Then you have the choice of what projection transform you‘d like to use (with perspective and isometric projections being most common), and whether shapes should be solid or semi-transparent or merely wireframe as shading choices are significant to the reality your portraying.
This would be an addition to 4D Toys I’d really like to see… a button which would be able to switch you from a sliced to a projected view of the space. However, I would say that might be a lot of effort as it would rely on a completely different rendering support code and such a capability wouldn’t be appropriate for the Miegakure game (it would make it too easy to spot things nearby which were temporarily out of your view because of your position and orientation).
In any case… great question. Wikipedia has a great entry cataloging a variety of such spatial transformations (collect ’em all in your graphics libraries!):
en.wikipedia.org/wiki/Graphical_projection
just look up the shape 'tesseract', that's the exact wire frame idea you're talking about for a cube

5.03 this is so beautiful I demand an hour long version
Instead of taking 3D slices of your 4D toybox, you could wire-frame the shapes and build a virtual 4D camera that takes 3D photos. Then we could see all 16 corners and 32 edges of a tesseract at the same time. If a smaller tesseract passes inside a larger one, it's really just farther from the camera in the same 4D direction.
With enough computing power you could do shading and ray-tracing in 4D, but a 1000x1000x1000 output image would contain a billion voxels and be very hard to view.
Are you from the future wtf
Mmm-hmm.

"3D cross section"
Brain hurty :(
Why? We’re not supposed to know what 4d looks like.
Similar to how a 2d plane (or piece of paper) is a SLICE of a 3d object.
A 3d object is basically PART of a 4d object.

Like like those “frames” of a 3D zoetrope. That would be like a 3D cross section if all of those ‘frames’ were a whole. That may or may not help.

I wouldn't say "it moves into the 3rd dimension" or "it moves into the 4th dimension" because they are already in there .. It moves within it not into it ..
For a 2D being there is no third dimension. Because we see their entire world (we're 3D beings) doesn't mean that 2D beings have a third dimension. The same applies to forth dimension so his wording is right.
@@shayanmoosavi9139 For the 2D being there was no 3D dimension, but we could see there was and that objects were just moving through it and not in and out of it.
I think the best way of putting it would be to say that it moves out of our current 3D slice of the 4th dimension. (The same way that the 3D objects were moving out of the 2D character's 2D slice of the 3rd dimension.)

This was from another video, I think a vsauce video I forget lmao
Why did you say that
Thank you for sharing this beautiful possibility
That might not be possible, because we 3 dimensional beings are bound to our respective planes. Since 4D beings aren’t bound to us, we might be unable to be harmed by them because they might have no choice but push our world around in the fourth dimension when they try to interact with it. Like if there was a two dimensional universe in our universe, we might not be able to stick our hands into it, because it has less dimensions than our hand, so we’d just push it through the third spatial dimension instead. However this means they’d be able to harm us by just ripping our universe apart which is way worse.
I want to see it! The rings becoming untangled are related to the timetravel paradox, in 4D there is a path around all sides of a binary fork 😮
Some mistakes: a 2d character can only see in 1d, we have two eyes that make an illusion of 3d,but we actually see only plane views of a 3d shadow of 4d objects.
Nerd
@@mericaman6388 why
@@mericaman6388 not nerd, but god
Yeah. 2D beings would actually see an object growing taller on a single axis instead of it expanding. So maybe we’re the ones who would see a shape expanding, and from everyone else’s POV, their 2D vision would see the 4-D object changing and growing in different ways.
Merica Man what have you done all your life clown
finally, the type of game I have always wanted.
I would try making this myself if I was better at programming. Another 4-dimensional game I'd really like to try would be a fps or similar, exploring a doom-like hell level, but there are obstacles you can't go around in 3d so you have to move "heavenwards" to get around. There would be a continuum of 3d layers between "heaven" and "hell", with the level design being gradually morphed from one extreme to the other
If you watch their other videos they're making something similar to your idea
Fun fact: doom was a 2D game creating a 3D illusion.

Explain the 4th dimention to the 2nd dimention guy
Oh god no
No u
would be the same as if we tried to understand the 5th dimension... ;)
J.Escape | “Imagine a pair of directions you can never go to. Now do that 2 times! That’s the 5th dimension.”
There's no distinction between the third and fourth dimension to a 2d guy. Anything that moved in one direction would be indistinguishable from something that moved in the other. It's merely a plane of travel that is skew from his plane.
Have you played around with 4D ray-casting?
It is how 3D objects are rendered on a 2D screen. (with 3D ray-casting)
You basically have point from with a bunch of rays(lines) that go through a rectangle. Each pixel on the screen gets the color the ray, that goes trough the rectangle at that position, hits first. (the rectangle is mapped to the screen). By moving the rectangle relative to the point you zoom (moving it closer/further) and rotate (moving it on a sphere) and by moving them both (but not relative to each other) you move the camera.
(actually it's not a rectangle but a part of the surface of a sphere but that doesn't really mater here)
You could do a similar thing by moving around a cuboid in the 4th dimension. And mapping it to pixels in a VR world.
(again it's actually the surface of a hyper-sphere)
Or you could try to go down 2 dimensions (in 3D it's moving around a line, in 4D a rectangle)
(the line is a segment of 1 of the circles on the surface of the sphere, the rectangle is a segment of one of the spheres on the surface of a hyper-sphere)
This should contain more information that just showing 1 3D slice and ray-casting that to 2D.
It should also look less weird (because objects actually hit the ground ect ( for a 3D being it's already confusing if you just see a slice of a 3d world but not confusing to see a ray-casted version). So it could be less confusing)
Also I want to see a Klein Bottle in your 4D toy box.
I wrote a simple rasterizer in 4D, but a true ray-tracer (for each pixel) would be very difficult to make efficient...
Interesting idea, but you would have to project the voxel structure you get onto a 2D screen. I think I'll experiment with that. (the problem that arises is the following: if your scene is full enough, most of those voxels won't be transparent. So you can't do the normal projections, but have to do something else, even though that would break the symmetry that would arise: a 3D shape would still look normal, as long as it is rotated correctly)
just like the old wolfenstien thats a good idea

Imagine a 4-dimensional being who can see inside of your body and push your organs around.
4th dimensional beings could literally see any point of 3d space of an object
@@Mreoewwmrow In fact they would see ALL points of 3D space as just a single line, or a string, they would need some kind of 4D viewing device that can show 3D (the way we have screens to see 2D pictures) to get a slice of the string, which would appear to them as a VR world fully 3D (not the way we see the world which is just 2D pictures with a framerate as fast as our brains can process) They would see 3D immersive still images as fast as their brains could process
Imagine a 4-dimensional waifu.
I deeply regret this comment.

@Stale Bagelz yep, it's more like 2d beings would see a 'line', but just conceptually. This line only has one dimension so it can't even be visualised as a line you could draw.

@@Ziegenhainy Well, he was talking about a specific part in the video, so he sort of did.
I don’t understand that one. Wouldn’t it still be attached in the fourth dimension?
To me, this is absolutely fascinating, but it is also very difficult to comprehend. For what I gathered, after watching other videos on the matter as well, one can see the 4th dimensions as a place where an object has all of its possible shapes stored/represented in. A 4D sphere might have any diameter variation between a minimum and a maximum diameter.Inside the objects is a collection of vertices and the many ways this vertices are connected to each other is stored in the 4th dimension. By moving back and forth thru the dimension, we can visualize each of said "ways of connecting vertices", and thus the various possible shapes.
I don’t understand what people are saying, everyone here can see what is going on, is simple, what are you guys, blind?
Wait... wrong dimension
@ryan7351 ryan7351 well think of the 2D world 3D object example in this video. It was probably not extremely difficult for you to get your head around how and why stuff behaves like it does there. A 4D being should equally be able to understand what's happening a lot more intuitively just seeing the 3D slice of a 4D object.

I enjoyed this video, but I do have one issue that kept bugging me throughout the entire thing. Whenever an object "disappeared", you said it "moved into the 4th dimension". They're all already in the 4th dimension, they're just moving along the 4th axis, which we can't visualize. Just a note, otherwise, great video, really entertaining and a pretty comprehensible explanation of an extremely complicated concept.
Yeah, I guess it would have been better to say "along" instead of "into"
"out of the slice we see" would have probably been better
