This is the official version of the R3DS dataset. You can request access and proceed to checkout the data:
```
git clone git@hf.co:datasets/3dlg-hcvc/rlsd
```

The dataset is structured into different folders:
```
mp3d_arch -- contains a subset of the Matterport3D architecture files that we have used
scenes -- contains the annotated json files for each scene
renderings -- contains various renderings of the annotated scene
    original_panoramas -- original panoramas (without annotations) from Matterport3D
    annotated_panoramas -- panorama renderings colored by object instance ids
    annotated_scene_hierarchy -- hierarchy of the annotated objects for each scene
    annotated_topdown -- topdown images of each annotated scene colored by object instance ids
annotated_model_ids.txt -- list of all model ids used to annotate the scenes
```

The annotated scene json has the following structure:
```
