Pentagons work in euclidean geometry. This is not non-euclidean.

Really? I felt the opposite. While Euclidean geometry is preferred by most, I find it more enjoyable to be in non-Euclidean space.

I'd love to see a feature where you can throw a ball. The inertia and speed could always be consistent so we could check how the trajectory and visual matches our expectations.
I HAD THE SAME THOUGHT! Just with a stone but, It would be so interesting to see and then also make sense of it all
I like this idea.
I don't know if you can do it. You're talking about a ball under free fall, then you'd have to modelate a gravity field. Since actual game engines manage the gravity regarding to an euclidian geometry you'd probably have to program it yourself. Then rises the question up where the hell would you put the gravity center or gravity line and set another reference in the frame
@@Edo_Aelio putting it that way got me thinkin now fuck
@@x_angel87 Yeah. I am not sure how someone would program this to work. My best guess have the player be attacted to the nearest surface. I am thinking like super Mario galaxy.
I would love to watch a VR version of this where we could look around ourselves cause some of those shapes was something else
This does work in VR (see the description).
Most people tend to just think of extra dimensions being added when speaking of non-euclidean geometry, I'm glad to see someone take us through some 3D geometries that are non-euclidean. It's strange and fascinating how much you can change the rules of nature and still have a functioning system.
Nothing is really being changed though, just how space is perceived. For example, to a photon travelling around a planet, it's just going in a straight line, it's space that is bending. Warped space is still technically flat, and the curve of space only really matters in determining the position/distance of something in relation to something else. It doesn't actually change anything else about how physics itself operates. Without a 4 dimensional material, a 3 dimensional object in 4 dimensional space, would still be just 3 dimensional. And that's the rub. We always hear about 4 dimensional shapes, but never about 4 dimensional matter itself, because that's where the theory essentially ends, because they haven't a clue of what 4 dimensional matter would even look like, especially when again, 4 dimensional is generally related to perspective and shapes, with zero consideration for the atomic level. And since 3 dimensional matter would still be only 3 dimensional in 4 dimensional space, it most certainly couldn't be matter at all as we know it, the entire makeup of atoms would have to change in an unfathomable way. But let's say a 3 dimensional object was somehow altered by 4 dimensional space, and like a klein bottle, shapes of matter actually looped in on themselves. Well that again wouldn't change much, because since it's 4 dimensional space, nothing is actually intersecting, so at least you get rid of the impossible problem of having 2 atoms occupying the same space. But that still means that nothing really changes about how the matter interacts. It would only really allow for some odd behaviors like if you had a long rectangular magnet with repulsive sides on each end, anything you put on either end would behave as if 2 ends are pushing from both sides, even though from a 3 dimensional perspective it would look like an extra magical force is coming from nowhere. So while bending space in such a way could be useful (and likely impossible), it would mostly be useful for technology. Another problem with 4 dimensional space, which likely doesn't exist at all and is more of a thought experiment, is that even if it did exist, nothing would really be able to form in it because of how drastically space is altering how things interact, it would be too chaotic. For example, imagine if the solar system was suddenly in 4 dimensional space. You might have the earth be on one side of its orbit, but getting gravity pull like it's closer to planets on the other side of the orbit. What this ultimately means is a stable orbit wouldn't be possible. Now imagine these space changes down to the atomic level. You could have electrons essentially leaving the orbit of their atom. Oops, no more atom. Self annihilation. Which means ironically, 4 dimensional space would probably be just a soup of particles that can't really coalesce into anything, with atoms essentially blinking in and out of existence as electrons come and leave from their electrons. This would also mean interactions between atoms at all would be intermittent and then broken again. It could also result in other behaviors, like particles becoming anti particles at seemingly random, and that's the ultimate proof that a 4 dimensional universe would actually be empty, because the whole thing would just self annihilate over time, leaving behind just energy and a soup of elementary particles.

Right? Imagine walking along a warping path, only to realize just in time that in two more steps you're going off a 90 degree angle cliff, but gravity is pulling on your mass in a way that makes it seem like you'll be fine if you try. The only way forward is going back the way you came, then up becomes down, so don't go up those twisted stairs; you'll fall. Jump in the hole instead to get to the top floor.
@@kilderok Going back the way you came might not be an option to you anymore as you may have shifted your angle ever so slightly midway through your realization and that was enough to put you off your trail by 90 miles.

I'm a programmer myself, but I can not imagine how hard it must be coding this...
What does the data structure look like to store non-euclidean geometry? 💀
Graphics engines are basically math function plotters, give it the right function and parameters, and you get euclidian geometry (ie. Draw things that are far away small) change the functions and parameters and you get all of this craziness. What was puzzling me is how they designed the "level" within the rooms. They either did it by code (coordenates) or they have also wrote an editor for varying geometries.
@@elkikex Yes, that's exactly what I mean... I am programming games, so I know a lot about game engines... But those "levels", or rather their geometry, needs to be stored somehow to be "plottet"... But there literally is no datastructure I could think of to store non-euclidean coordinates, right?

It was oddly relaxing, though the Sphere world was anxiety-inducing a bit. I'd LOVE someone to make a Lovecraftian game using these geometry perspective shifts. Lol
You've done great work visualizing the non-Euclidean geometries. If I might make a suggestion, it might be helpful to see Euclidean space morph into the other geometries, especially the really odd looking ones like Nil and Solv. Maybe start with fog obscuring the long lines of sight so that it still looks Euclidean because it's all local and then gradually lengthen the fog visibility length, thus giving a sense of how long the various lines-of-sight are. Or start with most of the map in darkness except near the viewpoint ("near" according to some underlying metric) and gradually widen the lighted area, giving a sense of when we're seeing the same thing multiple times along different geodesics because the multiple copies all get lit up at the same time. But it's just an idea. Good work!
There's an INFINITE number of geometries, formed by a combination of different basic geometries. Euclidean at x-y plane combined with hyperbolic at y-z plane is just one example, seen in this video. These can also go to higher dimensions.

Same! I just read The Call of Cthulu and I was wondering what exactly would "non-euclidean geometry" look like, it's a great horror trope to use the incomprehensible and now I have a better understanding!

Some Indie developer needs to pick this up to make an absolutely mind breaking puzzle game with non-euclidean geometry.
The RogueViz engine this video is made with was originally made for HyperRogue, and is also used in a few other smaller games (Nil Rider, Bringris, Relative Hell).

Great stuff! Is it possible to explain Sol to non-mathematicians? I'd love some kind of lecture or demonstration.
For Solv, the three dimensions of space don't work the same. As you travel up the vertical dimension, one horizontal dimension shrinks exponentially and the other grows exponentially. This means that the shortest path between two places at the same height can involve going up or down to get a shortcut, which is why light follows such paths and makes the floor appear to curve up/down in different directions.
@@SimonClarkstone Thank you! Good grief, that is absolutely bonkers.
@@kateorman The practical effect: if you build an elevated bridge in Solv in one direction, say, north-south, going along the bridge will significantly decrease the distance you need to go -- the higher the bridge the shorter the trip. But if you'd build a bridge in the perpendicular direction, east-west, the distance will *increase*. For east-west travels, you need a tunnel burrowed under the surface, not a bridge.
Here's the explanation by Zeno himself: This geometry has interesting features not exhibited by any 2D geometry, and is much weirder than all the geometries we have seen so far. It is also quite impressive visually. (It is kind of sad that the more interesting geometries have such boring names.) Imagine a plane, tessellate it with squares, and put a 1x1 cubes on each square. Then, put a 2x2 cube on each four cubes on the first level, a 4x4 cube on each four cubes on the second level, and so on. Also do the same in the direction below the plane (0.5x0.5 cubes, and so on). Consider this a map in R3 of a manifold, where the size of the cube corresponds to the metric (our model distorts the distances, all the cubes are actually the same size in the actual manifold) -- so, for example, we can get from the cube (0,0,0) to (1024,0,0) in just 21 steps (move 10 cubes upwards, one cube to the right (which corresponds to 1024 steps on the 0 level), and 10 cubes downwards). We already know this manifold -- this is the hyperbolic geometry H3, viewed in the Poincaré half-space model, with its "{4,4} on horospheres" honeycomb, already described. To obtain the Solv geometry, we also start with 1x1 cubes arranged in a plane, but on top of these 1x1 cubes, we put (1/2)x2 cuboids instead. On top of them, we put (1/4)x4 cuboids, and so on. For example, We can reach the cube at (1024,1024,0) from (0,0,0) in just 42 steps -- first, we go 10 levels upwards (in the Z direction), make one step in the Y direction, and 10 levels downwards. We are now in (0,1024,0). Now, go 10 levels downwards (as previously, we stack 2x(1/2) cuboids on the level below the original one, and so on), make one step in the X direction, and 10 levels upwards.

Thoughts: The calm narrative made me think of Powers Of Ten. I can imagine a similar documentary where we travel to progressively stranger geometries. Is there a canonically meaningful ordering of them? Altering one constraint at a time? Is it meaningful to transition slowly from one geometry to another? Can there be intermediate states as with fractal geometry? Is there a mapping that can enforce a different spacial geometry onto a fixed terrain? I would have liked to see the camera pitch and roll. And clearly someone needs to implement an FPS in other geometries. I like the idea of chasing someone from one geometry to another. Shooting would be confusing enough, but aiming at a target through a portal would be... interesting. And this obviously leads to a sequel called GeoPortal where your portal gun has selection buttons for what geometry you will be in after passing through. Lots of puzzle solving opportunities. What happens to conservation of momentum when transitioning? The gravity vector?
Now you’re thinking with portals

Not gonna lie. I wound up here a few weeks ago because I realized that I only had a faint idea of non-Euclidean space. I was good at Geometry and Trigonometry in HS, but it made my head hurt the whole time I was getting good at it. My head hurts again, but in a good way. Watching this feels the same way that looking at pictures of stars and galaxies when I was a kid felt like. It annoys me that there is such a huge hole in my understanding that I was unaware of.

This is wild. Imagine something like Control 2, which already delved into non-euclidian spaces, adding this kind of geometry into The Oldest House. So cool.
Many games are referred to as non-Euclidean but they are usually based on portals or perspective tricks; I have not tried Control 2 but I believe it is one of these. Actual non-Euclidean geometry is rare (in 3D: HyperRogue, Hyperbolica, some games in development), even games pretending to take place of spheres often do it wrong. Hopefully existing games and videos will inspire game developers to create more :)
Literally like DMT visuals.
I've never really understood non-euclidean geometries, but this video helped with all the different perspectives.

About a year ago from this comment, I was somehow dosed with THC from a vape that I tried. Unknowingly, I found myself at a restaurant with a friend who said he was going to the toilet. About 3 mins later, he explained he couldn't find his way to the toilet. At that point, I laughed and said I will show you where the toilet is. We both stood up and walked along the side of the place where we were sat and foundouselves at one corner of a room that we didn't recognise. Feeling disoriented, we asked the waiter who was nearby if she knew where the toilet was. She explained that the room we were in was not one that we should be trying to navigate in our current state of mind. Needless to say, we managed to return to our table and decided that our bladders could wait until the geometry made sense again.
Thank you for making this video.
This is fantastic, I loved the commentary! The explanations were detailed, but terse enough to be easily digestible.
Maybe I'm just slow, but it took me awhile to realize what she meant by "hybrid" geometries.
I like it when my sleep paralisis demon takes me to weird geometry land to show me some dubious mathematical blasphemies
this is beautiful o.o Thank you
Amazingly incredible & incredibly amazing!
Love to see this is blowing up on the algorithm! I got sucked into the mathematics of non-euclidean space traversal and rendering a couple years ago and came across your video "Ascending and Descending in Nil". When seeing this video just now I was reminded of that one, and I was delighted to see it is the same channel! Love your dedication to the subject of non euclidean space, it's an incredibly cool subject of mathematics. tldr; Love the channel, earned a sub!
Thank you for making this! That's what the Internet and 3d rendering really is good for. Also, the colors and textures are nice.
this is one of the best videos i've ever seen
Thanks for the excellent visualizations of various alternative geometries. Gives me ways to imagine those alternative geometries while reading Lovecraftian Cthulhu stories.
