Readiness
L2 · Semantic & material ready
Rationale
Manipulation L2: the platform ships ~2,500 objects/200 categories and 500+ scanned PBR materials; on import mass is computed from volume and density and friction is adjustable, with rigid/soft/cloth/fluid support, accessed via the TDW platform, hence L2.
Scale
3D model library ~2,500 objects / 200 categories (WordNet); material library 500+ (10 categories); 30+ indoor and 9 outdoor scenes (TDW paper (NeurIPS 2021 D&B Track) and platform docs: model library ~2,500/200 categories, 500+ materials; integrates PhysX (rigid) and NVIDIA Flex (soft/cloth/fluid).

Why it is listed

ThreeDWorld (TDW) is an open-source multi-modal physical simulation platform with a curated library of ~2,500 PBR objects across 200 categories and 500+ scanned materials, used for physical-scene and agent-interaction research.

Readiness assessment

Objects carry physically correct PBR materials and, on import, mass is computed from volume and density while friction is adjustable; TDW integrates PhysX for rigid bodies and NVIDIA Flex for soft-body, cloth and fluid simulation — an L2 interactive asset source.

Practical notes

The platform is MIT-licensed and the asset library installs with it, but individual model and material licenses vary, so verify each before redistribution.

Disclaimer: license and usage terms follow the official source — verify them yourself before use. This site indexes and links only; it does not host or mirror any asset file.
