Researchers have developed Pano2World, a novel system that converts a single indoor panorama into a fully explorable 3D Gaussian scene. This method bypasses the limitations of iterative completion and video generation models by reconstructing a coarse 3D Gaussian proxy. This proxy is then used to render guidance panoramas from nearby poses, which are fed into a panoramic diffusion model. The model employs View-Aware Attention Routing to enforce cross-view consistency, using both geometric constraints from guidance panoramas and semantic guidance from the source panorama. A Latent Feature Adapter further refines the process by distilling hidden features into a scene latent, which is then decoded into the final 3D Gaussian scene, outperforming existing methods on novel-view synthesis benchmarks.
