+# ProSceneverse
+
+Hand-designed 3D scenes (CAD, game environments, designed interiors and
+exteriors, urban scenes, stylized landscapes) curated from the TexVerse-1K
+Sketchfab crawl — the companion of
+[ScanSceneverse](https://huggingface.co/datasets/Stable-X/ScanSceneverse) which
+holds real-world photogrammetry scans.
+
+**74,624** textured designed scenes in glTF/GLB format, each with a
+machine-generated English caption, a scene-type label, and a thumbnail
+render.

+
+| column | type | description |
+| --- | --- | --- |
+| `scene_id` | string | 32-hex Sketchfab model id (primary key) |
+| `file_name` | string | Relative path to the GLB |
+| `thumbnail` | string \| null | Relative path to the JPEG preview |
+| `caption` | string | Gemini-generated English caption of the scene |
+| `category` | string | Curated scene type |
+| `decision` | string | Curation decision (`KEEP`) |
+| `scanning_ids` | list<string> | `scanned_by_*` tags (empty for designed scenes) |
+| `name` | string | Original Sketchfab model title |
+| `description` | string | Original Sketchfab model description (author-written) |
+| `tags` | list<string> | Author-provided Sketchfab tags |
+| `sketchfab_categories` | list<string> | Original Sketchfab category names |
+| `license_slug` / `license_label` / `license_url` | string | Per-scene license |
+| `author_username` / `author_display_name` / `author_uid` | string | Original Sketchfab author |

+
+## Loading
+
+```python
+from datasets import load_dataset
+ds = load_dataset("parquet", data_files="metadata.parquet", split="train")
+print(ds[0]["caption"], ds[0]["file_name"])
+```
+
+The GLB and thumbnail files are *not* inlined in the parquet. Resolve them
+relative to the dataset root, for example with `trimesh`:
+
+```python
+import trimesh, os
+root = "/path/to/ProSceneverse"
+mesh = trimesh.load(os.path.join(root, ds[0]["file_name"]))
+```
+
+## Licenses

+Every source model on Sketchfab ships with its own Creative Commons
+license. The per-scene license is recorded in the `license_slug`,
+`license_label`, and `license_url` columns — consult them before
+redistribution.
