Diogenes Megacity Metro Multicamera Archive v01
The Diogenes project has closed. This public archive preserves original capture artifacts and historical limitations for inspection and reproducibility. This archive manifest is fully transferred and verified. ARCHIVE_INDEX.json lists the exact tar files and fixed verification revisions. This update's verified manifest covers 48 objects / 1,089,301,193 public bytes, with 3 explicitly marked path-redacted copies. All listed public members have passed source/archive SHA-256, pinned Hugging Face LFS size/hash, and anonymous download checks.
Scope and historical status
Three 60-second four-camera validation groups: two camera-path groups from 2026-08-04 and one director-mode group from 2026-08-05. Original plans, dynamic-object/co-visibility measurements, the available QC report and camera/system metadata accompany the rendered video. No Unity scene source, meshes or project assets are distributed here.
Historical provenance says UCL-internal-validation-only; that label remains unchanged. The Unity Companion License permits authored-content distribution subject to its conditions, while this archive makes no unrestricted model-training or underlying-asset grant. Copyright 2024 Unity Technologies ApS and the UCL notice are retained.
The validation scene has obvious geometric/visibility defects in some sampled views, including obstructed or effectively blank frames. Player fields may mirror camera 1 because no separate player character existed; they must not be treated as independently measured human motion. Euler rotation order was not confirmed with the original delivery requester. Preserve these limitations when interpreting the technical measurements.
Reading the archive
Files are grouped into ordinary uncompressed TAR shards under archive/. Each tar preserves the listed relative paths and ends with its own MANIFEST.jsonl containing exact member sizes and SHA-256. The repository-level MANIFEST.jsonl now contains the verified SHA-256 of every public member. ARCHIVE_INDEX.json records each tar hash, size, member count and fixed verification revision.
Use tarfile.open(path, "r:") and extractfile(member) to read a member without extracting paths. Four-camera packages contain video_1..4.mp4, action_camera_1..4.json and systeminfo_1..4.json. The action-camera files are JSON arrays, not JSON Lines. Row frame and time identify the time sample; camera position, quaternion and intrinsics retain the original conventions. Technical systeminfo files describe the capture surface, not a physical-device identity.
Historical SHA/QC files are source records, not a new certification. A .public-copy.* suffix identifies a small derivative with operator-private paths removed; its source digest is retained separately, and original attestations must not be applied to its changed bytes. No numeric measurements, failed-QC results or eligibility markers were upgraded.
Review and limits
All structured JSON/JSONL metadata in the source scope was read, including all rows, and checked for account/contact/credential identifiers and operator-private paths. Archive directories and representative media/container metadata were inspected. Visual review samples frames; it is not exhaustive frame annotation or semantic audio review. Original media bytes are preserved and checked against available source SHA lists during transfer. Pinned Hugging Face LFS size/hash verification precedes source deletion.
This is an owner-authorized public project-closeout archive for inspecting capture quality, schemas and reproducibility. It is not certified or newly authorized model-training data. Original non_trainable, internal-validation, licence and QC statements are preserved; absent fields remain absent. Public access does not grant third-party game or asset rights. See NOTICE.md and the accompanying upstream notices.
