## Scenes

### 3D — Real insertions (`data_3d/real/insertions`)

| Scene |
| :--- |
| desk_in_london_bedroom |
| locomotive_in_train |
| plant_in_bouquet |
| sedan_in_c0e46b |
| truck_in_garden |
| 508850_in_4cea29 |
| d11d95_in_83d5f2 |

### 3D — Synthetic insertions (`data_3d/synthetic/insertions`)

| Scene |
| :--- |
| bathtub_57e_in_blend_57eadb |
| bed_bg3_in_blend_adfc14 |
| carriage_in_blend_85a1a6 |
| helicopter_in_blend_808c29 |

| sofa_blend_057_in_blend_057cff |
| table_7ea_in_blend_7ea0f8 |
| white_truck_in_blend_b433c8 |

### Rotation experiment (`data_rotation`)

Three scenes evaluated across three object rotations (rot0, rot1, rot2): `bathtub_57e`, `sink`, `white_truck`.

## Data format

Each scene is a COLMAP capture. Insertion scenes include a `masks/` folder with a binary mask per frame:

```
<scene>/
├── images/
├── masks/        # binary PNG masks, one per frame (insertion scenes only)
└── sparse/
    └── 0/
        ├── cameras.bin
        ├── images.bin
        └── points3D.bin
```
