WorldCrafter

Generates explorable, spatially consistent 3D environments from a single image or text prompt, supporting minute-scale navigation and camera-controlled world generation. Rather than explicit depth or geometric warping it uses a camera-queryable implicit memory, a memory encoder plus pose-conditioned readout, to decide which historical frames inform a new view. Evaluated on 145 scenes and 725 camera trajectories, reporting the highest overall VBench score among tested baselines, though the competitor names weren't stated. Code and a fast weights variant released.
