Qualitative results of VidEdit3D.

VidEdit3D propagates an edit from a single anchor view to a 3D Gaussian scene, supporting object additions, removals, appearance changes, and user-provided references.

Method

VidEdit3D reformulates 3D scene editing as trajectory-based video editing. Starting with a reconstructed scene and a user-edited anchor, it organizes smooth camera paths, propagates the edit across their rendered views, and refines the 3D representation.

VidEdit3D pipeline: Trajectory-Guided Rendering organizes source views into video clips, Flow-Aligned Video Editing propagates an anchor edit, and Region-Selective 3DGS Refinement updates target Gaussians. — Overview of VidEdit3D. Vector PDF ↗

Trajectory-Guided Rendering (TGR) selects target-supported views and constructs smooth video clips. Flow-Aligned Video Editing (FAVE) propagates the anchor edit with a pretrained video diffusion model and Editing Consistency Guidance. Region-Selective 3DGS Refinement (RS-GS) transfers the edited frames back into 3D while restricting updates to the target Gaussians.
