ShapeFusion: A Diffusion-based 3D Model for Localized and Disentangled Shape Editing

The proposed ShapeFusion model leverages diffusion models to enable diverse and fully localized edits on 3D meshes, while preserving the unedited regions. It introduces an effective diffusion masking training strategy that facilitates localized manipulation of any shape region, without being limited to predefined regions or sparse control vertices.
