This dataset is derived from ScanNet and from annotations built on it
(ScanRefer, Multi3DRefer, ScanQA, SQA3D, Grounded-3D-LLM proposals). The scene
files contain per-point coordinates of the ScanNet scans. Access is granted
only to researchers who have agreed to the ScanNet Terms of Use
(http://kaldir.vc.in.tum.de/scannet/ScanNet_TOS.pdf), for non-commercial
research. Requests are reviewed manually.

just3d data
Inputs for just3d (private code repository):
per-point dense features of 1193 ScanNet scenes from six 3D encoders, object mask
proposals, and the training annotations of the reproduced runs (anypoint 1-61..1-84 /
2-92..2-115). The repository root mirrors data/ in the code repository, so a
download goes straight into it.

0.2 GB | Training annotations, one file per mask source (*_clasp.json, region caption *_gt.json); PROVENANCE.json records each source file and its sha256. |

scene/dense_feature/<encoder>/ |
1193 each | 1.76 TB total | feat (bf16 [M, C]), coord_down ([M, 3]), inverse ([N]) per scene, for concerto_l (390 GB), utonia (314 GB), sonata (279 GB), concerto_b (279 GB), mask3d (190 GB), clasp (190 GB). |
The formats are specified in data/README.md of the code repository. Converted on
2026-10-01 from the anypoint feature stores; every object was verified against the
source store during conversion.
