Great work 👍👍👍
@@michac.8283 We'll it's being debated whether there's more dimensions beyond the third or not, but so far yes nobody has found proof of it. But it's still a possibility.
I think that in the theory of relativity time is a dimension. Acceleration and deaccélération in the time domain is basically actively rotating along the t axis in a sort of abstract way. However, it can't rotate more than 90 degrees since time would then flow backwards but it does behave similar to spatial dimensions when it comes to rotation. 0 degrees of rotation corresponds with an object at rest and at near 90 degrees of rotation time slows down/stops for the observer at a particular point as is the case near black holes.
Wonderful mechanics! A slider is cool, but I think it's an interesting idea to change w coordinate using the same way you change x, y, and z, as if it was another normal spatial dimension. Like you would normally walk/jump in games using WASD and space, you could walk along the w axis with, say, Q and E.
Hey there Jelle, I also am interested in making a 4d game and I just bumped into your video. I liked your effort but I guess you shoulf have used boolean operations on meshes combined with ray marching and ray marching collisions so as to get good graphics, optimisation and 4d too. Basically with this you will be able to import external 3d models which would be textured. I huess meigakure does this. Oris there a way to do raymarching with custom shapes made in a 3d editor like blender?
As far as I know, raymarching can't be used with triangle based models (or it can't be used optimally). Raymarching requires objects to be defined mathematically. So, for example a sphere at origin is defined as length(p)-r (there are a large number of articles on raymarching for further questions). So because of objects being mathematically defined Boolean operations are easier (I assume). Miegakure uses a method where it constructs all objects out of tetrahedra, takes the cross section and renders it with OpenGL. A 4D renderer that is based off of raymarching is generally easier to write, but slower (GPUs are optimized for rasterization). Sorry for writing an essay.

This is a major step forward for 4D games as a category. What you propose is a good idea, and would speed up the workflow for creating new models for 4D games. You would probably need to make a smaller program that takes a mesh and converts it into objects for ray marching, as I don't think this is possible to do in real-time. I'd be interested to see what the memory impact is, though. I could also be misunderstanding what you describe. Also, I don't think Miegakure used imported 3D triangle models. I'm pretty sure all the objects were defined in the game's code and generated at run-time. It doesn't use ray marching, but instead defines a new kind of triangle-based model that takes 4D coordinates instead of 3D. This allowed him to use traditional rendering techniques (fast and high-resolution), but unfortunately there's no software for making 4D models so he had to create them by directly typing in the model vertex-triangle data by hand.

One question, would it be possible to "visualise" 4d moving the 4d dimension really fast? There is a trick where people get various cameras and take a picture of the same thing at the same moment, but at various angles. Then if you keep changing between the photos really fast, the thing will look 3d. Could the same effect be used with 4d, to try to make us "see" 4d dimension?
Motion is about the best way we have of visualising the w axis, but it's worth noting that the "2D image -> 3D shape" trick leverages some inbuilt "software" in our brains that can construct a 3D understanding from flat snapshots from our eyes; this was essential for our animal ancestors to interact with a complex 3D world using collected light from one viewpoint at any one time. There isn't a comparative "static 3D -> 4D shape" in our biological software, which is why we struggle to grasp it as anything more than a 3D thing, changing over time.
This is amazing! I've loved diving into 4d research and honestly the games have been the best explanations of what it is for my primitive 3D brain! Gonna go play this rn. Perhaps get your unity package too... FourthDimensional, brother!
7:21 "I've also added the 4D framework on GitHub so you can make your own 4D bullying games!" I know it is boolean, but in my ears it sounded like bullying lol
when we see 2d, we can assume the third axis is pointing straight at our face. no matter how much we rotate an object in 2 dimensions, the third axis is always pointing straight at our face. so we can assume that the fourth axis is pointing straight into the eyes of a four dimensional creature when it is looking at 3d. and no matter in what way we rotate an object in 3d, the fourth axis will always be pointing to the 4 dimensional creature.
I've been contemplating adding one extra dimension in the form of making 4D models with Tetrahedron instead of 3D with triangles. Use a compute shader to fill the tetrahedrons on a 3D texture. And then scale it up and project a whole 4D world onto a 3D texture and simulate what a 4D being 's computer display would be like.
Sculptor: My Sculpture is great, but looking at it would take too long. Painter: Exists. Sculptor: What if I hire them to paint my sculpture so all the visitor has to do is look at an easy to digest painting?
we do have a limited perception of the 4th dimension if you consider that we cannot see time, we live in a small slice of time which is the present, we can remember the past but not observe it, and we are unable to perceive the future, we can only directly observe our 4th dimensional cross section slice as we travel on the time axis
Brilliant, i have the concept of a 4d puzzle Game in which you have to join pieces, but the pieces are in a 4d space, and you have to accomodate each piece to ita corresponding dimension in order to join them, and this the final piece of info I was looking for, thanks for your explanation I Hope you have a great day mu friend
Watching this I realized why time is considered the 4th dimension and how it’s not so much *the* 4th dimension, but more like *a* “4th” dimension, and really there could hypothetically be infinite dimensions.
The concept of this game is amazing, if you could fit a simplistic yet beautiful 3D artwork, a compelling story and an open world i can tell you that it will be a boom! . Meigakure does it really well but i can tell the potential of this mechanic is just overwhelming. Maybe a Mario Galaxy themed game of a planet corrupted by time and space. I mean just wow i can't imagine all the possibilities!
That's very interesting, the movements in the 4th dimension are still quite simple but I was able to move intuitively through it, which is strong! Didn't understand it much better but that's very playable ^^ It looks quite a lot like we are playing with time too
"If you don't see something, it's probably somewhere along the fourth dimension". This game teaches you to think outside the box. Well, outside the 3D box, at least)
Hi! I've played it - really nice game) Hope you'll continue work on that) I've noticed, that now the W axis is percieved simply like "time". The game mechanics wokrs here as if W is a timeline... Maybe that's just my 3D brain can't imagine anything non-3D, but I still thing there could be mechanics, that may lead player to feel that's not timeline, but another axis. To feel the W itself. Yeah some people say that the 4-th dimension is the Time itself, but i don't think so. The Time is just a sequence of events, but not a space axis itself. And I don't think the sequence (=time) of our 3D lives is just intersection of some 4D objects passing through our 3D space. No. I mean the timeline and the W-axis are two seperete "axises". There could be some events and sequenses both in 3D and 4D world. There can be time both in 3D and 4D world. Maybe you could add a timeline for 4D objects in your game so they could live their life in time? That may colapse everyones brain and PCs, but it could give you more mechanics)) Great work, thank you!
1 dimension game is just a line. Not a one pixel high line, but a game that you can’t go up, down, forward, or backwards. Maybe a rythme game where you have to move in specific patterns
At least we can move _ana_ and _kata_ throughout this world, but a shame we won't be able to ever see it. I remember William Sleator coming to my school and explaining what a 2D person would see if a 3D object or person passed through his dimension. The entire concept of going to and experiencing the 4th dimension was in "The Boy Who Reversed Himself", easily one of my favorite books of all time. Even though it's meant for young adults, it's still a great read.
*@Jelle Vermandere* What happens if you couple the 4'th dimension slider to the render distance? So the further away an object is, the further away you also see it in the 4't dimension? So you see an object in the distance, but as you walk towards it, it fades into the 4'th dimension, so you have to move through the 4th dimension to find it again. (you might have to somehow substitute one of the regular axis for the 4th axis i guess, or just let the 4th dimension determine when you can see specific object, or something like that?)
4D viewing would benefit of a virtual 3D monitor surface that can be moved and rotated on a 2D physical viewing surface, to make it more analogous with our typical 3D viewing. The idea here is to be able to view 4D objects simultaneously in their entirety instead of slicing them. Viewing 4D sceneries on 3D monitor would also benefit of the idea of "lateral transparency". It is not transparency in the actual sense of the word, but an artificial viewing aid. Think about a 4D scenery with a ground, a sky, and an object in the middle of the picture. Normally we would only see the virtual monitor (for example shaped as a cube) filled with brown at the bottom and azure at the rest of its height. The object in the middle would be obscured out of sight like a spoon in a glass of milk. Instead, we would need the ground and sky to be somewhat transparent so that we can see the object in the middle. We would need also the object to be transparent, to a lesser degree, to see other objects that may be in front of it in the 4D coordinates but appear as immersed into it in the 3D coordinates. The general rule would be that the smaller the details, the less transparent they appear on-screen. This viewing perspective would have the vanishing point in the middle of the cube and let the viewer freely rotate the cube to facilitate the visualizing. If there are animation capabilities, it would be highly recommendable to show the animations as if recorded by a handheld 4D camera. The small, erratic movements of the camera would greatly help in adding 4D parallax hints into the view.
The orbs don't make sense When you move across the fourth dimension the button stops being pressed but the orb is still on the button you just can't see it
And your slider, if it was rotational rather than back and forth it would make for a more modern look and feel infinite and challenging. Perhaps levels where there is no slider, but doing certain tasks changes the W axis as well. Would have a nicer feel.
Here’s a fun thought experiment of the 4th dimension. Imagine the St Louis Arch suddenly appearing in the 2D universe of Flatland. The base of the arch lies on Flatland. To an observer in Flatland, they will see two large rectangles . They would have no idea that two rectangles were part of the same object. Now imagine of the leader of Flatland decides to commission the movement of one of the rectangles to make way for a new road. They would send out their 2D little tow truck and try to remove the one rectangle. But when they push away this rectangle, the 2nd rectangle moves the exact same direction. They would be left wondering how the two seemingly unrelated rectangles are entangled to one another. What if this is how quantum entanglement works? What if the particles that are seemingly far apart, are actually connected to each other in the 4th, 5th, 6th dimension? This would explain how one particle changing its spin can instantaneously affect the spin of another particle lightyears apart from each other.

There isn't a comparative "static 3D -> 4D shape" in our biological software, which is why we struggle to grasp it as anything more than a 3D thing, changing over time.
This is amazing! I've loved diving into 4d research and honestly the games have been the best explanations of what it is for my primitive 3D brain! Gonna go play this rn. Perhaps get your unity package too... FourthDimensional, brother!
*physics teachers when you ask them what the 4th dimension would look like:* "well yes, but actually no..."
*this dude:* "haha unity go brrr"

"I've also added the 4D framework on GitHub so you can make your own 4D bullying games!"
I know it is boolean, but in my ears it sounded like bullying lol
The fourth dimension still makes no sense to me... 😅
i find this very enjoyable because i feel like you have the best dutch accent ever!
haha, thanks, I guess ;)
@@JelleVermandere BTW i love the project and i can't wait to see more!
Fun fact : we can't see things that are 2D
😮
Yeah we can?
@@Dude_for_christI think what he means is that a 2D object in a 3D world is impossible as it would be infinitely thin
@@gabegamez1018 yes but their is an infinitely thin layer of every 3d object
@@Dude_for_christ oh yeah, never thought of that
when we see 2d, we can assume the third axis is pointing straight at our face. no matter how much we rotate an object in 2 dimensions, the third axis is always pointing straight at our face. so we can assume that the fourth axis is pointing straight into the eyes of a four dimensional creature when it is looking at 3d. and no matter in what way we rotate an object in 3d, the fourth axis will always be pointing to the 4 dimensional creature.
still faster than the time it takes for my crush to respond
*pain*
I've been contemplating adding one extra dimension in the form of making 4D models with Tetrahedron instead of 3D with triangles. Use a compute shader to fill the tetrahedrons on a 3D texture. And then scale it up and project a whole 4D world onto a 3D texture and simulate what a 4D being 's computer display would be like.
Sculptor: My Sculpture is great, but looking at it would take too long.
Painter: Exists.
Sculptor: What if I hire them to paint my sculpture so all the visitor has to do is look at an easy to digest painting?
You did in one video what Miegakure's creator is never going to reach
This got me thinking so much, it’s just a fascinating topic. Great vid
That's awesome bro. I think you did great job explaining the 4th dimension to me. I think it's an interesting game and fun 2.
This guy 3D printed painted a glued a little astronaut just for a explanation.
Respect man, respect
This is amazing! I didn't even know you could ilustrate 4 dimensions in such ways.
I have to say you nailed the 4th dimension thingie. ❤️ Loved it
Oh, so moms can see into the fourth dimension. That explains why we can't find things and they can. LOL
Finally, a competitor for 4d craft! This battle will be legendary!
jelle vermandere is doing his best work to make fun stuff
Watching this video when I realized... I've played this game! Great work!
I'm amazed by his effort. He even 3d printed a model. Dang
It was a 4D printed model, it just LOOKS 3D.
@@AlericResident lol
This looks so damn cool and the pixel style makes it even better
i realy love the whole theory behind 4 dimensions and this was a realy cool way to represent it
we do have a limited perception of the 4th dimension if you consider that we cannot see time, we live in a small slice of time which is the present, we can remember the past but not observe it, and we are unable to perceive the future, we can only directly observe our 4th dimensional cross section slice as we travel on the time axis
he is talking about the spatial fourth dimension, not the temporal.
This is incredible, so good to see the algorithm picked this up 😍
#blessed
This is makeing my head hurt and I LOVE IT KEEP IT UP
Nice work
Brilliant, i have the concept of a 4d puzzle Game in which you have to join pieces, but the pieces are in a 4d space, and you have to accomodate each piece to ita corresponding dimension in order to join them, and this the final piece of info I was looking for, thanks for your explanation I Hope you have a great day mu friend
That’s really good. Take it all the way man!
Watching this I realized why time is considered the 4th dimension and how it’s not so much *the* 4th dimension, but more like *a* “4th” dimension, and really there could hypothetically be infinite dimensions.
Wow, this is fantastic. Love your work!!
When watching this, you need an iq of 261 or more to try to comprehend 4D shapes without frying your brain
The concept of this game is amazing, if you could fit a simplistic yet beautiful 3D artwork, a compelling story and an open world i can tell you that it will be a boom! . Meigakure does it really well but i can tell the potential of this mechanic is just overwhelming. Maybe a Mario Galaxy themed game of a planet corrupted by time and space. I mean just wow i can't imagine all the possibilities!
I've actually read Flatland. Really interesting book. Had me thinking a too much at times about what you showed. Really cool explanation and video!
props to this guy he made a 3d printed explanation on the plot of the game. Which probably took awhile
That's very interesting, the movements in the 4th dimension are still quite simple but I was able to move intuitively through it, which is strong! Didn't understand it much better but that's very playable ^^ It looks quite a lot like we are playing with time too
This man just figured out the 4th dimension with that not even being his main goal
"If you don't see something, it's probably somewhere along the fourth dimension". This game teaches you to think outside the box. Well, outside the 3D box, at least)
Hi! I've played it - really nice game) Hope you'll continue work on that)
I've noticed, that now the W axis is percieved simply like "time". The game mechanics wokrs here as if W is a timeline... Maybe that's just my 3D brain can't imagine anything non-3D, but I still thing there could be mechanics, that may lead player to feel that's not timeline, but another axis. To feel the W itself.
Yeah some people say that the 4-th dimension is the Time itself, but i don't think so.
The Time is just a sequence of events, but not a space axis itself. And I don't think the sequence (=time) of our 3D lives is just intersection of some 4D objects passing through our 3D space. No. I mean the timeline and the W-axis are two seperete "axises". There could be some events and sequenses both in 3D and 4D world. There can be time both in 3D and 4D world.
Maybe you could add a timeline for 4D objects in your game so they could live their life in time? That may colapse everyones brain and PCs, but it could give you more mechanics))
Great work, thank you!
He's done 2D, 3D and 4D, we all know what we need next: 1D! I'm serious, I wonder what sort of games he could make when limited to only 1 dimension
1 dimension game is just a line. Not a one pixel high line, but a game that you can’t go up, down, forward, or backwards. Maybe a rythme game where you have to move in specific patterns
@@blendee2721 True and false. You can make a playable game that can move in the 3.(width height length)
this looks really cool nice job man
Simply Amazing work. Well..actually..complex amazing work. Subbed.
This is like, next level game design. Now we need this as a real 4D Video Game on Pc or somethin
At least we can move _ana_ and _kata_ throughout this world, but a shame we won't be able to ever see it.
I remember William Sleator coming to my school and explaining what a 2D person would see if a 3D object or person passed through his dimension. The entire concept of going to and experiencing the 4th dimension was in "The Boy Who Reversed Himself", easily one of my favorite books of all time. Even though it's meant for young adults, it's still a great read.
Wow, I didn't think it was possible to make a 4D game in Unity! The creators of Miegakure made their own engine.
This reminds me of 4D Miner. I'm watiting for it to blow up. I hope it will. It's real fun to play around.
OMG dude that was beautiful. Good Job
You are a genius and passionnante !
Subscribed and liked !
Ahh, A Short Hike, such a beautiful short game. :D

What happens if you couple the 4'th dimension slider to the render distance?
So the further away an object is, the further away you also see it in the 4't dimension?
So you see an object in the distance, but as you walk towards it, it fades into the 4'th dimension, so you have to move through the 4th dimension to find it again.
(you might have to somehow substitute one of the regular axis for the 4th axis i guess, or just let the 4th dimension determine when you can see specific object, or something like that?)
4D viewing would benefit of a virtual 3D monitor surface that can be moved and rotated on a 2D physical viewing surface, to make it more analogous with our typical 3D viewing. The idea here is to be able to view 4D objects simultaneously in their entirety instead of slicing them.
Viewing 4D sceneries on 3D monitor would also benefit of the idea of "lateral transparency". It is not transparency in the actual sense of the word, but an artificial viewing aid. Think about a 4D scenery with a ground, a sky, and an object in the middle of the picture. Normally we would only see the virtual monitor (for example shaped as a cube) filled with brown at the bottom and azure at the rest of its height. The object in the middle would be obscured out of sight like a spoon in a glass of milk. Instead, we would need the ground and sky to be somewhat transparent so that we can see the object in the middle. We would need also the object to be transparent, to a lesser degree, to see other objects that may be in front of it in the 4D coordinates but appear as immersed into it in the 3D coordinates. The general rule would be that the smaller the details, the less transparent they appear on-screen.
This viewing perspective would have the vanishing point in the middle of the cube and let the viewer freely rotate the cube to facilitate the visualizing.
If there are animation capabilities, it would be highly recommendable to show the animations as if recorded by a handheld 4D camera. The small, erratic movements of the camera would greatly help in adding 4D parallax hints into the view.
The orbs don't make sense
When you move across the fourth dimension the button stops being pressed but the orb is still on the button you just can't see it
And your slider, if it was rotational rather than back and forth it would make for a more modern look and feel infinite and challenging. Perhaps levels where there is no slider, but doing certain tasks changes the W axis as well. Would have a nicer feel.
So it's programmed in 4D, rendered in 3D, and displayed in 2D?
Now that's pretty cool.
Here’s a fun thought experiment of the 4th dimension. Imagine the St Louis Arch suddenly appearing in the 2D universe of Flatland. The base of the arch lies on Flatland. To an observer in Flatland, they will see two large rectangles . They would have no idea that two rectangles were part of the same object. Now imagine of the leader of Flatland decides to commission the movement of one of the rectangles to make way for a new road. They would send out their 2D little tow truck and try to remove the one rectangle. But when they push away this rectangle, the 2nd rectangle moves the exact same direction. They would be left wondering how the two seemingly unrelated rectangles are entangled to one another. What if this is how quantum entanglement works? What if the particles that are seemingly far apart, are actually connected to each other in the 4th, 5th, 6th dimension? This would explain how one particle changing its spin can instantaneously affect the spin of another particle lightyears apart from each other.
Dude, you are the modern day Carl Sagan explaining about 4D with 3D sections :D
