PhySIC evaluation release
Per-frame predictions of PhySIC
(SIGGRAPH Asia 2025, arXiv) on
PROX-quantitative (178 frames) and RICH (100 frames), with the
reconstructed scene each one was optimised against. They reproduce the paper's
Table 2 with the evaluation code in the repository's
eval_release/,
which downloads this data on first run.
What is here
release_data/prox/<recording>/<frame>.npz compact tier, 15 MB
release_data/rich/<frame>.npz 9.8 MB
release_data_full/prox/<recording>/<frame>.npz full scene clouds, 7.6 GB
release_data_full/rich/<frame>.npz 5.6 GB
Both tiers hold the same predictions and give identical numbers. The compact
tier keeps the scene points the contact metric can reach (3.6k per PROX frame,
~4.5k per RICH frame); the full tier is the complete reconstructed cloud
(2.0M / ~2.6M points, floor plane included).
Per-frame fields
| field | what it is |
|---|---|
init_*, final_* |
SMPL-X parameters (betas + 6D rotations) and camera translation, before and after scene-aware optimisation |
K |
predicted pinhole intrinsics |
contact_deco |
the image-based contact prediction the optimiser was given |
scene_points, scene_normals |
reconstructed scene, metric scale, camera frame |
visibility_mask |
body vertices projecting into the segmented person (PROX only) |
contact_pred_reference |
contact mask as computed by the pipeline, re-derived and checked by the evaluation |
No dataset imagery, depth maps, meshes or ground truth are included. Ground truth comes from your own downloads of PROX and RICH, and the bodies use SMPL-X, each under its own licence.

Released for non-commercial scientific research only, under the same terms as PROX and RICH.
