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:

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:

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.

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:

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:

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.
