How to make hidden objects simulatable in real scenes?

Reconstructing real-world scenes from photos often leaves objects incomplete and impossible to simulate physically due to occlusion and limited views. SAM3D-Phys combines scene reconstruction with generative 3D models to infer missing geometry, then anchors recovered objects back to their actual locations through physics constraints and texture refinement. The result: clean, simulatable objects you can interact with in a reconstructed environment.
