What's this about?
A system that generates large, freely explorable 3D worlds from open-ended text while keeping the whole space globally coherent and locally detailed at the same time.
What exactly is "3D world generation"?
It's turning a text prompt into an actual navigable 3D environment (think a game level or simulation), not just a flat image. The hard part is consistency — the far side of the world must still make sense when you walk to it — which is why "at scale" is the claim.
Why it matters
Explorable generated worlds feed games, simulation, and training grounds for embodied agents.
