+# ScanSceneverse
+
+Real-world scanned 3D scenes (photogrammetry / environment + landscape scans)
+curated from the TexVerse-1K Sketchfab crawl — the companion of
+[ProSceneverse](https://huggingface.co/datasets/Stable-X/ProSceneverse) which
+holds *designed* scenes.
+
+**125,023** textured scan scenes in glTF/GLB format, each with a
+machine-generated English caption, a scene-type label, and a thumbnail
+render. Scenes that carry a `scanned_by_*` author tag also include the
+originating device id under `scanning_ids`.
