# Sand3D Explorer

Browse Sand3D, Sandflow's open dataset of 3D objects written as code: every object comes with
the short [sand3d](https://github.com/Sandflow-ai/sand3d) program that builds it. Filter by
dataset, family or joints, search by words or by look, read and copy a program, and open the
object in 3D where a GLB was built for it.

The programs come from Sandflow's iterative agentic reconstruction pipeline. Each was run again
under sand3d, in a fresh process, and kept only when it rebuilt the stored object.

## How it runs

A FastAPI process serves one static page and a JSON API, on the free CPU tier. At start it
downloads the datasets listed in `config.json` (the `HF_TOKEN` secret reads them), keeps their
metadata and programs in memory and their renders in one file on disk, then reads
`Sandflow/sand3d-explorer-assets`: one GLB per object for a varied sample, and one image
embedding per render. A text query is encoded on CPU by the same open image-text model the
renders were embedded with.
