| # SeaShapes |
|
|
| 3D models of maritime objects, each with its real-world size and its source. One folder per asset, holding the model and a preview. `metadata.jsonl` describes every asset, one row each, and `schema.json` defines the fields. |
|
|
| ## Query |
|
|
| In the Data Studio SQL console, or anywhere DuckDB runs: |
|
|
| ```sql |
| SELECT id, category, length_m, width_m, licence |
| FROM 'hf://datasets/SEA-AI/seashapes/metadata.jsonl' |
| WHERE list_contains(tags, 'containers') AND length_m BETWEEN 80 AND 100; |
| ``` |
|
|
| Pin a file by commit, never by branch: |
|
|
| ``` |
| https://huggingface.co/datasets/SEA-AI/seashapes/resolve/<commit>/<id>/<id>.glb |
| ``` |
|
|
| ## Fields |
|
|
| | Field | Meaning | |
| |---|---| |
| | `id` | Folder name | |
| | `file_name` | Preview image, `<id>/preview.png` | |
| | `title`, `author`, `source_url`, `licence` | Attribution; `licence` is an SPDX identifier | |
| | `category`, `tags`, `description` | What the object is; `tags` are free filters | |
| | `length_m`, `width_m`, `height_m` | Real overall size, keel to top for a vessel | |
| | `size_source` | How the real size is known; model units are arbitrary | |
| | `file`, `format`, `size_bytes`, `sha256` | The file | |
| | `front_axis` | Where the front points in the file; omitted when it is glTF's `+z` | |
| | `triangles`, `textures`, `texture_max_px` | Mesh detail | |
| | `modified` | Whether the file differs from what the source offers | |
| | `added` | Date added | |
|
|
| `schema.json` is the authority; a row that fails it is not added. |
|
|
| ## Adding an asset |
|
|
| No clone needed: fetch the small files, add the asset, upload only what changed. |
|
|
| ```bash |
| hf download SEA-AI/seashapes --repo-type dataset --local-dir seashapes --exclude "*.glb" --exclude "*.png" |
| cd seashapes |
| ``` |
|
|
| 1. Put the model at `<id>/<id>.glb` and append its row to `metadata.jsonl`. Leave `sha256` and `size_bytes` out; the check fills them in. |
| 2. Render its preview: `uv run tools/preview.py <id>`. |
| 3. Check every row: `uv run tools/validate.py`. Rows whose folder is here are checked against their files, the rest against `schema.json`. |
| 4. Upload in one commit: |
|
|
| ```bash |
| hf upload SEA-AI/seashapes . . --repo-type dataset --include "<id>/*" --include metadata.jsonl --commit-message "Add <id>" |
| ``` |
|
|
| Pin the new commit, never `main`, wherever the asset is used. |
|
|
| ## Licences |
|
|
| | Files | Licence | |
| |---|---| |
| | `<id>/<id>.glb` | The author's, given per row in `metadata.jsonl` | |
| | `<id>/preview.png` | The model's licence and attribution; each is a render of the model, modified: rendered by SEA.AI | |
| | `metadata.jsonl`, `schema.json`, `README.md` | CC BY 4.0, SEA.AI | |
| | `tools/` | Apache-2.0, SEA.AI | |
|
|
| Credit the author and link the source when you share a model or work made from it. Every row of `metadata.jsonl` carries its `title`, `author`, `source_url` and `licence`, and models from Sketchfab embed the same in their glTF `asset.extras`: |
|
|
| ```sql |
| SELECT title, author, source_url, licence |
| FROM 'hf://datasets/SEA-AI/seashapes/metadata.jsonl'; |
| ``` |
|
|
| Models from Sketchfab are the GLBs it offers for download, unmodified. Their authors do not endorse SEA.AI or this dataset. |
|
|
| All files are provided as is, without warranties of any kind, to the extent the law allows; see each licence. |
