# Data guide

Each folder contains one reconstructed scene, identified by its original Wanderland capture ID.

- Lengths are in metres; rotational limits are in radians. Native simulator scenes use Z-up.
- `parts.json` lists exported parts; `source/refs/twin_manifest.json` records the object inventory.
- `environment_pbr.usda` contains the enhanced appearance and added assets; `base/model.glb` is the base representation.
- Dimensions, labels and physical properties describe the generated scene.
