- perilunar 7mo agoVery cool!
- freetonik 7mo agoVery cool! Would be great to be able to rotate/zoom the 3D space.
- Schlagbohrer 7mo agoIt can at least be rotated, as I did so.
- psini 7mo agoAm able to rotate/pan/zoom with firefox on desktop using the mouse buttons and scroll wheel
- xnorswap 7mo agoNot only can you rotate with right-click, you can also pan and zoom and manually add cells.
- freetonik 7mo agoHuh, somehow it didn't work for me the first time (chrome, macos), but now it works.
- ralferoo 7mo agoThis is the kind of visualisation that obvious in retrospect, but I don't think anybody's done this before. Very nice. I think the only change I'd make really is to give the top layer and obviously different colour so you can view from the top and see the current configuration. Currently it just looks confusing because e.g. a - oscillator looks like + instead.
- layer8 7mo agoThe “fading” animation (what the top-down view here looks like, minus the shrinking due to perspective) already did exist in the 1980s, just not the 3D-zation of it.
- xnx 7mo agoHere's one from 2018: https://www.reddit.com/r/math/comments/9xfquc/3d_visualization_of_john_conways_game_of_life/ https://www.reddit.com/r/math/comments/9xfquc/3d_visualizati... One from 2 weeks ago: https://www.instagram.com/reel/DUxkEiWDS-q/ https://www.instagram.com/reel/DUxkEiWDS-q/ I'm sure there is much older.
- thih9 7mo agoI like this one, from 1 year ago; a tall structure rendered in Blender: https://www.youtube.com/watch?v=D50iRzBI3qc https://www.youtube.com/watch?v=D50iRzBI3qc
- ralferoo 7mo agoThat 3D printed one is amazing!
- AStrangeMorrow 7mo agoYeah I helped build a 3D parametric engine a few years back at my company. This kind of stacked game of life was one of the first script I added to test it, alongside the 3D terrain generation using Perlin noise. I highly doubt I was the first one (and I mean that was 4 years ago so the one from 2018 definitely precedes it), however it had a bunch of extra features like colors associated with the initial states and the colors would also propagate and merge alongside the cells
- JKCalhoun 7mo agoCame here to say the same: remarkable, just make the very top layer hard white, or outlined, or something that contrasts with the falling history.
- jlarocco 7mo ago
- boomlinde 7mo agoHmm, shouldn't this pattern be perfectly stable? o o o o In this simulation it seems to oscillate between two patterns. Very interesting visualization either way!
- qchamaeleon 7mo agoI'm guessing you're looking at three cells switching between vertical and horizontal. O O to OOO and back again. O
- boomlinde 7mo agoAah, yes, that's probably it.
- JKCalhoun 7mo agoA "tub": https://conwaylife.com/wiki/Tub https://conwaylife.com/wiki/Tub
- WillMorr 7mo agoVery nice visualization, the fade out really adds to the organic feel. I've been playing with a similar system but designed for 3d printing, it's simple to make it self-supporting by just drawing a line from each parent to each child which is neat.
- huhtenberg 7mo agoI am a simple man. I see Game of Life in the title, I upvote the post.
- madcaptenor 7mo agoI am a slightly more complicated man. I see Game of Life in the title, I upvote the post. I also upvote this comment.
- builderhq_io 7mo ago[flagged]
- vanderZwan 7mo agoVery nice visualization! I thought this was going to be like a Game of Life variation I came up with about 15 years ago where you stack multiple layers of 2D Cellular Automata, allow each layer to have their own rule set, do single steps of each and then define the interactions between the layer as applying Boolean operations before doing the next step (e.g. set layer 1 = 1 xor 2, layer 2 = 1 xnor 2). I'm pretty sure that's effectively a subset of what you can encode with a multi-state CA (you can after all interpret each layer as a "bit", so e.g. with two layers each point can be in "four states", meaning any give combination of rulesets ber layer + masking operation should have an equivalent four-state CA, but I never bothered to figure out how one would map from one to the other, and then the hard drive where the code was stored crashed so I forgot about it.

- SsgMshdPotatoes 7mo agoWow, this kinda blew up since first post, what happened :0
- VibeSchema 7mo agoWhat does stacked mean? Is this just 3D game of life where cells die unless 5-6 neighbours and come alive with 4 neighbours? But very cool, would also be cool if you could specify initial configurations perhaps. (BTW, github link seems broken.)
- VibeSchema 7mo agoAh found answers in README of vnglst/stacked-game-of-life, nice idea!
