| # NL3D anonymized multi-object review sample |
|
|
| This is an anonymized review-time sample selected from the NL3D synthetic |
| multi-object split. It contains 8 settled multi-object scenes and 26 unique |
| source GLBs, with no repeated source object across selected scenes. It is not |
| the complete synthetic training set. |
|
|
| ## Selection |
|
|
| - `scenes/mixed`: 3 scenes containing both conductor and transmissive materials. |
| - `scenes/transparent`: 3 scenes emphasizing transmissive/clear materials. |
| - `scenes/metal`: 2 scenes emphasizing conductor and mirror-like reflection. |
|
|
| Every scene is copied in full. The original 50-view `rgb`, `diffuse`, `glossy`, |
| `transmission`, and `mask` directories are retained, together with |
| `transforms.json`, `composition.json`, `material.json`, `mesh_raw.ply`, and |
| `points_gt.ply`. |
|
|
| The referenced source assets are deduplicated under |
| `objects/objaverse_lvis_real`. All object references in the metadata use |
| portable repository-relative paths. HDR environments are identified by their |
| source filenames without retaining local machine paths. |
|
|
| ## Provenance and licensing note |
|
|
| The source meshes are a curated subset of Objaverse assets. This sample does |
| not assign a new license to those third-party source assets; downstream users |
| must verify the applicable per-object provenance and license before further |
| redistribution. The complete NL3D data and documentation will be released after |
| the double-blind review period. |
