NVIDIA recently unveiled its latest AI system, Lyra 2.0, which can generate large-scale, interactively explorable 3D environments from just a single photo, effectively addressing issues of 'spatial forgetting' and 'temporal drift' in long-distance viewpoint movement. Lyra 2.0 achieves information routing by storing 3D geometric data for each frame, avoiding redundant generation, and employs a self-reinforcing training strategy to maintain long-term visual stability. The system supports interactive exploration and camera trajectory planning, with generated 3D assets exportable directly to physics engines, providing a high-quality solution for robotic simulation training and virtual scene construction.
