### Update
- 2025.3.22: Update the preprocessed data to include vertex normals. The data size will increase by 10GB after adding the normals. To save data load time during training, we suggest removing some unused information.
- 2025.3.20: Release Articulation-XL2.0 preprocessed data (a NPZ file includes vertices, faces, joints, bones, skinning weights, uuid, etc.).
- 2025.2.16: Release metadata for Articulation-XL2.0!

### Overview
This repository introduces <b>Articulation-XL2.0</b>, a large-scale dataset featuring over <b>48K</b> 3D models with high-quality articulation annotations, filtered from Objaverse-XL. Compared to version 1.0, Articulation-XL2.0 includes 3D models with multiple components. For further details, please refer to the statistics below.

</p>
Note: The data with rigging has been deduplicated (over 150K). The quality of most data has been manually verified.

### Metadata
We provide the following information in the metadata of Articulation-XL2.0.
```
uuid,source,vertex_count,face_count,joint_count,bone_count,category_label,fileType,fileIdentifier
```

### Preprocessed data
We provide the preprocessed data that saved in NPZ files, which contain the following information:
```
'vertices', 'faces', 'normals', 'joints', 'bones', 'root_index', 'uuid', 'pc_w_norm', 'joint_names', 'skinning_weights_value', 'skinning_weights_row', 'skinning_weights_col', 'skinning_weights_shape'
```
