ABO material-intrinsics WebDataset
Preliminary publication smoke for the IDArb-compatible Amazon Berkeley Objects material-render conversion. The smoke shard contains 10 complete objects with 91 views and three environment lights per object.
Each tar member is one compressed NPZ containing rgb, albedo, roughness, metallic,
normal, mask, depth, and meta_json. Source-specific material channels, camera conventions,
normal axes, masks, and background compositing are normalized during conversion.
Source: Amazon Berkeley Objects. ABO is licensed under CC BY 4.0. Credit for the data must be given to Amazon.com; cite the ABO CVPR 2022 paper when using it.
Production publication is in progress. Root shard-*.tar files contain exactly 500 unique objects
except the final source remainder; matching provenance and SHA-256 records live under
manifests/. smoke/shard-000000.tar remains the independently verified validation artifact.
