No. WFC is fundamentally different from this.

Yep. People have been doing this kind of stuff for computer games for decades. It's actually not that difficult. It's not clear what novel problem is being solved here.

Indeed, this has been described in the past as "The Oatmeal Problem" [1]

You reminded me of this https://book.leveldesignbook.com/process/layout

And Valve I think used to have a series on level design, involving from big to small and "anchor points", but I seem to have misplaced the link.

” The generated scenes are walkable and suitable for navigation/planning evaluation.”

Maybe the idea is to create environments for AI robotics traini ng.

Consider the levels generated in any roguelike.

Consider the patterns generated by cellular automata.

Both tend to stay interesting in the small scale but lose it to boring chaos in the large.

For this reason I think the better approach is to start with a simple level-scale form and then refine it into smaller parts, and then to refine those parts and so on.

(Vs plugging away at tunnel-building like a mole)

Or at least coherent.

True, it sounds (and looks) a lot like https://scp-wiki.wikidot.com/scp-3008

i'm thinking a new version of LSD dream emulator could be really interesting.

The description in the linked YouTube video for some reason has more info than the github repo:

> We tackle the challenge of generating the infinitely extendable 3D world — large, continuous environments with coherent geometry and realistic appearance. Existing methods face key challenges: 2D-lifting approaches suffer from geometric and appearance inconsistencies across views, 3D implicit representations are hard to scale up, and current 3D foundation models are mostly object-centric, limiting their applicability to scene-level generation. Our key insight is leveraging strong generation priors from pre-trained 3D models for structured scene block generation. To this end, we propose WorldGrow, a hierarchical framework for unbounded 3D scene synthesis. Our method features three core components: (1) a data curation pipeline that extracts high-quality scene blocks for training, making the 3D structured latent representations suitable for scene generation; (2) a 3D block inpainting mechanism that enables context-aware scene extension; and (3) a coarse-to-fine generation strategy that ensures both global layout plausibility and local geometric/textural fidelity. Evaluated on the large-scale 3D-FRONT dataset, WorldGrow achieves SOTA performance in geometry reconstruction, while uniquely supporting infinite scene generation with photorealistic and structurally consistent outputs. These results highlight its capability for constructing large-scale virtual environments and potential for building future world models.

An unpublished paper.

It looks more like the Stanley parable.

With a quarter the size of the development team, 'cause productivity!

Games have used procedural world generation since at least the 1980s, and on 8-bit home computers. Glancing through the video and webpage, the results don't look much different from what's possible with traditional Wave Function Collapse tbh.

It's not just you. The generated stuff - in my opinion - doesn't make any sense at all, with regard to structure or meaning. Unless, perhaps, the aim was to generate some kind of badly designed Ikea store.

Yeah, I think either the method doesn't work well, or there is something off with their tuning.

Their block-by-block generation method seems to be too local in its considerations, where each 3x3 section (= the ones generated based on the immediate neighbors) looks a lot more coherent than the 4x4 sections and above. I think it might need to be extended to be less local and might also in general need to be paired with some sort of guidance systems (e.g. in the office example would generate the overall floor layout).

Not only not realistic but also not explicit: not so much as a peachy bottom in sight.
