| # just3d data |
|
|
| Inputs for [just3d](https://github.com/torridfish/just3d) (private code repository): |
| per-point dense features of 1193 ScanNet scenes from six 3D encoders, object mask |
| proposals, and the training annotations of the reproduced runs (anypoint 1-61..1-84 / |
| 2-92..2-115). The repository root mirrors `data/` in the code repository, so a |
| download goes straight into it. |
|
|
| ## Layout |
|
|
| | Path | Files | Size | Contents | |
| |---|---|---|---| |
| | `annotations/` | 7 JSON + `PROVENANCE.json` | 0.2 GB | Training annotations, one file per mask source (`*_clasp.json`, region caption `*_gt.json`); `PROVENANCE.json` records each source file and its sha256. | |
| | `scene/mask_proposal/clasp/` | 563 | 1.0 GB | Grounded-3D-LLM (CLASP) top-100 proposals, packed masks over the full point set. | |
| | `scene/mask_proposal/gt/` | 1193 | 0.8 GB | ScanNet ground-truth instance masks. | |
| | `scene/dense_feature/<encoder>/` | 1193 each | 1.76 TB total | `feat` (bf16 `[M, C]`), `coord_down` (`[M, 3]`), `inverse` (`[N]`) per scene, for `concerto_l` (390 GB), `utonia` (314 GB), `sonata` (279 GB), `concerto_b` (279 GB), `mask3d` (190 GB), `clasp` (190 GB). | |
|
|
| The formats are specified in `data/README.md` of the code repository. Converted on |
| 2026-10-01 from the anypoint feature stores; every object was verified against the |
| source store during conversion. |
