REST3D: Reconstructing Physically Stable 3D Scenes from a Single Image (shirleymaxx.github.io) AI

REST3D is a single-image 3D reconstruction framework that builds a gravity-support scene-tree representation of object physical states and inter-object relationships, then refines an initial image-to-3D reconstruction with scene-tree-guided, physics-constrained optimization to eliminate violations like floating or penetration while preserving visual consistency. The paper reports reduced physical errors and improved simulation stability on synthetic and real datasets, and demonstrates VR-based human-object interaction using the stable reconstructed scenes.
