G-Objaverse: 3D Objects with Material Intrinsics and 40 Views

G-Objaverse material-intrinsics WebDataset provides a preliminary conversion of 3D objects. The initial shard contains 10 complete objects, each with 40 views and one unknown illumination. Each object's data includes normalized channels for rgb, albedo, roughness, metallic, normal, mask, depth, and metadata, authored by danielkorth and last updated on July 18, 2026.

Use Cases

• Train material estimation models based on the provided albedo, roughness, and metallic channels.
• Develop view synthesis algorithms based on the 40 views per object.
• Benchmark 3D reconstruction techniques using the provided depth and normal maps.
• Study illumination effects in rendering using the single unknown illumination condition per object.

Strengths

• Contains 10 complete 3D objects, providing a concrete starting point.
• Each object has 40 views, offering multiple perspectives.
• Data includes multiple material channels (albedo, roughness, metallic, normal).
• Source-specific material channels and conventions are normalized during conversion.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description is preliminary, describing a 'smoke shard'; the full dataset scope is unclear.

Provenance

Source
