NL3D/synthetic_composite_sample

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.
