Datasets:
| # Scripts | |
| Derives both CSV indexes from the assets. Pure Python 3, no dependencies: GLB metadata is read | |
| from each file's glTF JSON chunk and the binary payload is never touched, so probing the whole | |
| 23 GB collection takes about ten seconds. | |
| | script | purpose | | |
| |---|---| | |
| | `glb_probe.py` | Library + CLI. Parses one `.glb` and returns rig, animation and geometry stats. | | |
| | `build_dataset.py` | Walks every asset once and writes `../metadata.csv` and `../animations.csv`. `--link` also hardlinks a source directory into `../glb/`. | | |
| ```bash | |
| python3 build_dataset.py # rebuild both tables in place | |
| python3 build_dataset.py --src /path/raw --link # ingest a fresh download | |
| python3 glb_probe.py ../glb/<file>.glb # inspect a single asset | |
| ``` | |
| ## Notes on the probe | |
| - Kinematic-tree roots are counted as joints whose parent is not itself a joint, so | |
| `num_skeleton_roots > 1` marks a disconnected or multi-tree skeleton. | |
| - Clip duration comes from the `max` of each animation sampler's input accessor, which glTF | |
| stores in the JSON chunk. | |
| - `animated_joints` intersects a clip's target nodes with the skin's joint set, separating clips | |
| that drive a rig from clips that only move object-level nodes. | |
