NVIDIA presents Lyra 2.0, a research system that builds explorable 3D worlds from one image

NVIDIA researchers present Lyra 2.0, which turns a single image into a 3D world that users explore along a camera path they choose.

The system combines video generation with 3D reconstruction and learns to correct visual errors that build up over a path, which NVIDIA says keeps the world consistent when users return to places they have already visited.

The paper, code, and demos are published on the project page, according to an NVIDIA AI post on X.
