SNAP3D: Physically Grounded 3D Parts for Assembly from a Single Image
Summary
The paper presents SNAP3D, a physics‑guided pipeline that converts a single image into a set of 3D parts that can be assembled without interpenetration. By using simulation‑driven connector placement and a new physics‑based evaluation, the method yields assemblies that are both geometrically accurate and stable enough for 3D printing.
- The framework resolves inter‑part penetration and builds a contact graph, then adds parameterized connectors at contact surfaces.
- Connector placement, orientation, and size are refined using physical simulation feedback to ensure gravity‑stable assemblies.
- A physics‑based evaluation protocol tests assembly validity and stability, complementing traditional geometric metrics.
- Experiments demonstrate substantial improvements in physical realizability and stability while preserving geometric quality versus existing generators.
3D graphics and vision engineers building editable or printable models will care because the approach guarantees physically assemble‑able parts directly from images.
