PhysInsert is a research paper on inserting a reference object into a scene, adapting both the object and its surroundings so the result looks physically plausible.
Data: The Insert World dataset uses strictly aligned, Blender-rendered counterfactual pairs, with object references across viewpoints and lighting conditions.
Method: Geometry-Guided Adaptation adds a VGGT geometry stream alongside image and text streams. A 2D Object-Scene Spatial Supervision step covers object occupancy and environmental changes.
Results: Experiments on PhysInsert-Bench and DreamBooth show better image fidelity. A user study reports more accurate placement and improved lighting integration, perspective and pose plausibility.
