InternScenes SSP records

Per-object and per-scene encoder records for the InternScenes indoor scene corpus: sampled surface geometry paired with DINOv3 patch features.

405,139 records, 425 GB, delivered as ~110 uncompressed tar shards of about 4 GB each.

group records size
objects 381,365 253 GB
scenes/gen 14,089 133 GB
scenes/real 9,583 38 GB
scenes/synthetic 92 0.3 GB

objects/objects-000NN.tar          # unpacks to objects/<uid>.npz

proj_W_1024x3201.npy               # DINO -> SSP projection

index.csv.gz lets you locate a single record without unpacking anything:

import pandas as pd
idx = pd.read_csv("index.csv.gz")
idx[idx.record == "scenes/synthetic/0059.npz"]        # -> which shard to download

Record schema

Each .npz stores raw components. Scene records concatenate their objects; object records hold one.

key shape dtype meaning
mesh_pos (N, 3) float32 patch centroids, normalized frame
mesh_nrm (N, 3) float32 patch normals
pooled_cov (M, 1024) float16 DINOv3 patch features, covered patches only
cov (N,) bool which patches carry appearance features
owner (N,) int32 index into the group_* arrays (scene records)
group_key / group_uid (G,) str per-object identifiers
group_cat (G,) str category label (structure for walls/floor/ceiling)
group_bbox (G, 9) float32 9-DoF box: centre, extent, rotation
scene_C / scene_S (3,) / () float32 normalization offset and scale
n_per_object () int32 patches per object
ssp_dim, ls_pos, ls_nrm () int32/float32 encoder parameters
scene_set, scene_name () str provenance

pooled_cov is compacted to covered patches, so scatter it back before use:

import numpy as np
z = np.load("scenes/synthetic/0059.npz")
pooled = np.zeros((len(z["mesh_pos"]), 1024), np.float32)
pooled[z["cov"]] = z["pooled_cov"]

World coordinates: mesh_pos * scene_S + scene_C.

proj_W_1024x3201.npy is a seeded draw and reproducible independently:

W = (np.random.default_rng(0).standard_normal((1024, 3201)) / np.sqrt(1024)).astype(np.float32)

Known gaps

Five synthetic scenes have no record (0004, 0026, 0088, 0090, 0097).
