[Bringris] Tetris Line Clear but in hyperbolic space*

Anyway, I know that 2020 hasn't been an active year for the channel, and I'd like to apologise for that. The pandemic and lockdowns caught me in the middle of moving out from France to England, and I've been more or less stuck at my boyfriend's parent's with 7 people in the house and without most of my stuff since March. Hopefully though, I'll be able to find a place for my boyfriend and myself soon enough, giving me better conditions to create stuff, both materially and mentally. I wish you all the best for 2021, and that we all make it a far better year for ourselves.

I actually started to understand what was going on by the end and that scares me

[@Oshisaure]

Have you figured out yet that you can tuck through walls by the same logic that lets T-spins exist in regular Tetris, except here it's just sliding the piece through a wall

[@alexsc7505]

Imagine if they added this to Hyperbolica as a minigame

[@ZenoRogue]

Actually the original idea for this came from a discussion in the Hyperbolica discord :) This uses the HyperRogue engine, but we have decided not to make it a mini-game in HyperRogue because it does not use any HyperRogue worldbuilding, and it is fun enough to be a separate small game. (Contrary to most other minigames in HyperRogue)

Tetris but the game it’s made on got injected with a pinch of LSD™️ Lilla, it’s okay that you couldn’t produce as many videos as you would have hoped in 2020! Even if we all wanted more content, your health comes first, and I’m more than happy to know that you’re with Lanterns, some place safer! And if you ever need to take longer of a break, that’s totally okay! Happy New Year, and I wish you both the best for this year! ❤️

Thank you lots, I wish you the best for 2021 too

[@StompyRoA]

All I can think of while watching this video is the virtual boy Tetris game but on acid.

[@Oshisaure]

yeah kinda. It's 3D tetris except you replace 2 of the dimensions with hyperbolic space

[@ninjatintin9074]

Hyperbolic space is basically negative curved space, the space that is played in the video is called H2 x E (Two Hyperbolic dimensions and Euclidian height), an example is when you put 5 or more squares in a vertex (point).

[@NumLokke]

Hyperbolic space is so cool

Oh, that is an absolute mess to figure out. I think my eyes need a fix soon.

[@bracken8782]

Hyperbolic space visualizations do that to you. It's hard to wrap your head around.

[@henrikljungstrand2036]

This is a pretty small quotient of the hyperbolic plane (times an extra dimension of height), it might be a tesselation of Bring's surface perhaps. I wish the developers would put some borders though, that delineate the finite nature of the surface, but that you can translate the surface through (similarly to borders for a square/rectangular tiling of a torus, that you can translate through the border). This way you wouldn't be overwhelmed by the seemingly infinite nature of the hyperbolic plane that this surface is a quotient of. Since the "world" of this game is essentially finite, not infinite.

[@Oshisaure]

Yeah, it took me a little while at first to realise that this thing works essentially like a torus and that it's the same finite space wrapping around. It might be hinted at with some pieces like the line piece reaching so far out you can see them multiple times at once when placing them, but an actual drawn border would make it more obvious, I agree.

[@ZenoRogue]

Indeed, it is a tessellation of Bring's surface (hence the name Bringris). The game has a a bounded well mode too, though. Although one property of hyperbolic shapes is that a large proportion of the squares are on the boundary/corners, which is less nice (and makes looped manifolds and unbounded spaces more appealing IMO).

[@henrikljungstrand2036]

@@ZenoRogue Ah, good that that you have a bounded mode, i have yet to play the game for myself. 🙂 Is it possible to translate the world through the boundary as well, so you can move any tile into the visible center? I didn't even realise the connection between the name Bringris and Bring's surface, lol! 😅

[@ZenoRogue]

@@henrikljungstrand2036 Not sure what you mean here -- you can center on any tile inside the bounded well, but you cannot look at the bounded well from the outside.

[@henrikljungstrand2036]

@@ZenoRogue That's exactly what i meant! Thank you! I would like to download this game, but my pc stopped working, i don't know if it exists for Android (like HyperRogue), and i'm too poor to buy a new computer now.

[@bracken8782]

Honestly i can understand most of this except the rotation system. Holonomy is extremely confusing to me and i still don't understand it.

[@bracken8782]

Update: i think i get it, but it's easier to visualize on a spherical plane and not a hyperbolic plane. Basically as you move around non-euclidean space, you accumulate extra rotation even if your perspective stays fixed. Take a direct 90 degree turn enough times and the piece should have rotated in a direction. In hyperbolic space, it's the opposite direction you traveled, so if you want to rotate a piece to the left, you take five 90 degree turns to the right.

[@bracken8782]

What i mean by easier to visualize on a spherical plane is that you can see the effects of holonomy by just using your hand and a ball (or even just your hand if you're feelin’ dangerous.) put your hand on the front of the ball. Move it up to the exact top, then, without changing your hand’s orientation, move it to either side of the ball. Then move it back to the front where it started. Your hand should have rotated 90 degrees in the direction you moved, even though you never really changed its perspective. That's called holonomy, and it's how the rotation system works in his game.
