SNAP3D: Physically Grounded 3D Parts for Assembly from a Single Image
The paper’s core claim is that single-image 3D parts need to survive assembly, not just look complete.
SNAP3D adds a physics-guided step that fixes part collisions, infers where neighboring pieces should touch, and places connectors at those contact surfaces. It then uses simulation feedback to adjust connector position, direction, and size so the assembled object is more stable under gravity while keeping the generated geometry. The authors report improved physical realizability and stability versus other part-aware 3D generators, and say they validated parts through 3D printing and real assembly. HF Daily Papers' note
