| ## Download |
|
|
| You can download individual subsets using `hf download`: |
|
|
| ```bash |
| hf download WalkerCH/Streaming3D DL3DV/ |
| hf download WalkerCH/Streaming3D GSO30/ |
| hf download WalkerCH/Streaming3D NAVI/ |
| hf download WalkerCH/Streaming3D GSO/ |
| ``` |
|
|
| Only the subset you request will be downloaded; you do not need to download the entire repository. |

|
| ## DL3DV |
|
|
| 16 indoor/outdoor scenes from the DL3DV dataset. Each scene directory contains: |
|
|
| ```text |
| DL3DV/ |
| scene_<id>_<hash>_<name>/ |
| colmap/ # COLMAP reconstruction output (features, matches, sparse model) |
| da3/ # DA3 format data |
| images/ # Source images (PNG) |
| sam3_masks/ # SAM3 segmentation masks |
| split.json # Train/test split |
| transforms.json # Camera transforms |
| scenes.csv # Scene metadata |
| scenes selected.csv # Selected scene list |
| ``` |
|

|
| ## GSO30 |
|
|
| `GSO30` is a 30-object subset derived from Google Scanned Objects. Each object |
| directory contains training renders, evaluation assets, and the original object |
| mesh/material files. |
|
|
| ### Object List |
|
|
| ```text |
| alarm backpack bell blocks chicken cream elephant grandfather grandmother hat |
| leather lion lunch_bag mario oil school_bus1 school_bus2 shoe shoe1 shoe2 |
| shoe3 soap sofa sorter sorting_board stucking_cups teapot toaster train turtle |
| ``` |
|
|
| ### Directory Structure |
|
|
| ```text |
| GSO30/ |
| <object_id>/ |
| meshes/ |
| model.glb |
| model.obj |
| model.mtl |
| texture.png |
| render_spiral_100/ |

| 000.png ... 099.png |
| masks/ |

| model/ |

| render_mvs_25/ |
| model_norm.glb |
| model_norm.obj |
| model_norm.mtl |
| model/ |
| 000.png ... 024.png |
| 000.npy ... 024.npy |
| ``` |
|
|
| Some object folders also include auxiliary metadata, thumbnails, or legacy |
| render folders. The benchmark protocol uses the paths above. |
|
|
| ### Usage |
|
|
| For training or reconstruction input, use all 100 images from: |
|
|
| ```text |
| GSO30/<object_id>/render_spiral_100/images/{000..099}.png |
| ``` |
|
|
| The corresponding masks are stored in: |
|
|
| ```text |
| GSO30/<object_id>/render_spiral_100/masks/{000..099}.png |
| ``` |
|
|
| Camera metadata for the 100 spiral views is available in: |
|
|
| ```text |
| GSO30/<object_id>/render_spiral_100/transforms.json |
| GSO30/<object_id>/render_spiral_100/model/{000..099}.npy |
| ``` |
|
|
| For evaluation, use the normalized GLB mesh and the 25 provided camera views |
| from `render_mvs_25`: |
|
|
| ```text |
| GSO30/<object_id>/render_mvs_25/model_norm.glb |
| GSO30/<object_id>/render_mvs_25/model/{000..024}.npy |
| ``` |
|
|
| The matching reference renders for those views are: |
|
|
| ```text |
| GSO30/<object_id>/render_mvs_25/model/{000..024}.png |
| ``` |
|
|
| In short, the default protocol is: |
|
|
| 1. Train or reconstruct from all `render_spiral_100/images` frames. |
| 2. Evaluate by rendering or comparing against `render_mvs_25/model_norm.glb` |
| using the 25 camera poses in `render_mvs_25/model/*.npy`. |
