This could be a great way to make backrooms horror environments!
I've dreamed of a NeRF-powered backrooms walking simulator for quite a while now. This approach is "worse" because the mesh seems explicit rather than just the world becoming what you look at, but that's arguably better for real-world use cases of course.
I wonder if they also have a strategy for deleting generate tiles, otherwise the infinite is limited to the size of available memory. I also wonder if with their method can exactly recreate tiles that have been deleted. Or in other words, that they have a method for generating unique seeds for all tiles. The paper does not give much technical details. If the seed has a limited size and there is a method for generating seeds for each 2D coordinate, I wonder if it is possible to make a non-repeating infinite world. I think it is not possible with a limited size seed.

Any ideas of how it would different and better compared to "traditional" PCG? Seems like it'd give you more resource consumption, worse results and less control, neither of which seem like a benefit.
Is it just me, or some of the places it generates are just not realistic? Like a small area of some kind which is a dead space, and there is a giant window into it.

It's about generating interesting virtual space!
