Lyra
Lyra is an AI framework that generates camera-controlled walkthrough videos and lifts them to 3D worlds.
Lyra is an AI framework developed by NVIDIA that creates explorable generative 3D worlds. It generates camera-controlled walkthrough videos and lifts them into 3D via feed-forward reconstruction. The system addresses spatial forgetting by maintaining per-frame 3D geometry for information routing and solves temporal drifting using self-augmented training histories. Users can interactively plan camera trajectories, revisit explored regions, and export scenes as 3D Gaussians or meshes. The generated environments integrate with physics engines like Isaac Sim for robot navigation and simulation.
