In short, fuck the cubes, you just need to squeeze the space between the balls, make all the balls the same size, and blur the boundaries between the balls, turning them into foam.

Okay, to hell with balls and cubes, I’ll just take a grid and make pipes along the grid.

Damn, but it turned out to be torn too.
To hell with balls, grids, cubes, we’ll just take dots.

If you don’t know quantum mechanics, then I think it will be useless for you to explain what quantum foam is, but if you can’t wait, you can try to ask ChatGPT to explain it in simple language as someone who is unfamiliar with quantum physics.
No, let’s go back to the cube version and make them the same size.
No, I want to puke from these stinking voxels… 
Let’s fix this terrible flaw!
Let’s close the space between the boxes.
Now you need to create a smoothed version.

You know, I still think you’re a mad genius, right?
Thanks to Chudik Compression, we can liken the quantum foam Noodle to a biome like in Minecraft, although it seems to me more like a farland…

In other words, turn quantum foam into spaghetti.
Or we need distant lands like in Minecraft, then we need to make the parameters as in the video.
Although I call it a Super honeycombs.
When I used to program on mayavi, I got this structure.
Great, we’ll replace the torn isoface of quantum foams with geoids!

I accidentally came across an interesting topic called ‘PBR raymarching metaballs’, and decided to replace the interfaces with Ray Marching instead of Marching cubes, and I got a gasoline cube, that’s what I call it!

I’m almost close to realizing my goal, there’s not much left!

Well, I’ve finally modeled the quantum foam!

Let’s compare what happened and what became.
Before:
After:
All that remains is to solve the problem of the torn interface and that’s it.
And here are those notorious distant lands of quantum foam!
I liked this implementation, and I came up with a new backroom level - Iron Clippings.

This is a level that represents an endless space created from razor-sharp steel stones.
