| # Stereo-sections artifacts |
| Large artifacts of the project behind "Sweep World Models: Identifiability and Calibrated Transition Testing for 2D-to-3D |
| Microstructure Generation" (CVPR 2027 submission), and of its earlier stages ("What can sections say about volumes?": |
| slice-to-volume generation of 3D two-phase microstructure from 2D sections, identifiability analysis, StereoCal calibration, |
| few-section protocol E6). Code, paper |
| sources, the complete registered method log and all result JSONs are in the companion GitHub repository (private during |
| review: rayjang/stereo-sections). |
|
|
| Layout (tar files are plain `tar cf` archives of the directories named; untar in place next to the code): |
| - `ckpt/` -- every checkpoint (`ckpt_*.pt`, `ckpt_*.npz`): cross-material 3D EDM priors (`ckpt_blibC_3d_cond3long.pt`, |
| `ckpt_blibM_3d_cond3long.pt` with their descriptor normalisation `.npz`), per-target 2D section / pair models, the |
| StereoCal policies (`ckpt_{T}_3d_cal_*.pt`) and every earlier variant. |
| - `results/` -- per-run result files (`cal_*.json`, `calscore_*.json`, `maintab/`, tables, logs), `maintab/` -- metric caches. |
| - `local/data.tar` -- the preprocessed binary crops of all targets (`data/{T}_train.npy` = 400 random 32^3 crops of the |
| sectioned half, `data/{T}_test.npy` = non-overlapping cubes of the held-out half, bands, fraction laws, the few-section |
| budget files `data/{T}_k{k}_d{d}.npz` and `data/{T}_trainvol.npy`). |
| - `local/SliceGAN.tar`, `remote/SliceGAN.tar` -- official SliceGAN trainings (generators, logs, example tifs). |
| - `local/microlad_runs.tar` -- MicroLad baseline runs. |
| - `local/samples_{prefix}.tar`, `remote/samples_{prefix}.tar` -- every generated pool (`samples/{T}_{stem}.npy`, float16, |
| +1 pore / -1 solid); `remote/` holds the pools and checkpoints produced on the second machine (cathode targets). |
| Targets: carbonates bfKetton, bfIndiana, bfPortland, bfEstaillades, bfKME90583Cb; cathodes beNMCsg, beMJ1cath, |
| beTangcath, beN1u, beN1c, beN2u, beN2c, beN3u, beN3c, beN4c; development sandstones bcBerea, bcBuffBerea, bcClashach. |
| beNMCsg, the NMC example volume distributed with SliceGAN, is a 252x252x253 crop of the NREL cathode behind beN2u with the |
| carbon-binder domain counted as solid (beN2u counts it with the pores), so the fifteen paper targets come from fourteen scans. |
| Source scans are public datasets (see the paper's references); the 10-13 release above stores only derived crops and |
| generated volumes. The 10-25 release below also mirrors source data and public pretrained weights. |
|
|
| ## Release 2026-10-25 (`release_20261025/`) |
| Every artifact that the GitHub repository does not hold and that was produced or changed after the 10-13 release, as raw |
| files at their workspace paths (the paper at that date). |
| - `release_20261025/local/` -- first machine: `kikuchi/samples/` (generated pools, 128 volumes of 64^3 per stem: official |
| SliceGAN `*_sgoff10T*`, pair critic `*_slab2_*`, fixed-target and projected-critic routes `*_swm_*` / `*_pwm_*`, the |
| verifier-RL arms, the fragmented control `*_official_s0_bk_*`, and earlier pools), `kikuchi/SliceGAN/Trained_Generators/` |
| (all trained generators, with epoch-8/9 snapshots where saved), checkpoints and caches at the top of `kikuchi/`, |
| `kikuchi/data/`, `kikuchi/real/` (the source X-ray CT scans as downloaded), `baselines/`, `microlad_runs/`, `ckpt/`, |
| `results/`, `data/`. |
| - `release_20261025/remote/` -- second machine, same layout. Directories holding many small files are packed as one plain tar |
| each (`baselines/DimExDAM_gb10.tar`, `baselines/TPDM.tar`, `microlad_runs/{target}.tar`); each tar's member list is the |
| `.tar.txt` next to it. |
| - The four official 100-epoch SliceGAN runs on bfEstaillades, bfPortland, beN2c and beN4c were stopped at epochs 73 to 85 |
| (method log, 2026-10-25 17:34); their snapshots and last generator are included but are not 100-epoch results. |
|
|
| Third-party material: `kikuchi/real/` and `data/` contain copies of public datasets (X-ray CT scans, materials databases, |
| CIFAR-10), and `ckpt/` and `baselines/` contain public pretrained weights, mirrored as they were used in the experiments. |
| Their original licenses and citations apply (see the paper's references). The CC-BY-4.0 license above covers the files |
| produced by this project. The four Imperial carbonate scans (figshare 1230044 to 1230047, CC BY 4.0) are courtesy |
| of Qatar Carbonates and Carbon Storage Research Centre, Imperial College London. |
|
|
| ## Release 2026-11-02 (`release_20261102/`) |
| Everything that the GitHub repository does not hold and that was still missing here on 2026-11-02, from both machines, as raw |
| files at their workspace paths. A file already present in an earlier release with the same path and size is not repeated. |
| - `release_20261102/local/` -- first machine: `kikuchi/samples/` (generated pools of the final paper: SliceGAN over seeds and |
| epoch snapshots `*_sgoff10_s{1,2}_ep{8,9,10}T*`, SliceGAN at its published 100-epoch stop `*_sgoff100*`, the pair critic, |
| MicroLad, the Gaussian random field `*_grf*`, the fragmented control and the route pools), `kikuchi/SliceGAN/` (trained |
| generators not in earlier releases), world-model and encoder checkpoints at the top of `kikuchi/`, `kikuchi/data/`, |
| `kikuchi/data64tmp/`, `kikuchi/kbudget/` arrays (perturbation twins and score caches), `kikuchi/real/` (source scans; the |
| Bentheim slice stack as `kikuchi/real/bentheim.tar`) and `microlad_runs/`. |
| - `release_20261102/remote/` -- second machine, same layout: generated pools, SliceGAN generators, MicroLad runs (each |
| target's training slices as `microlad_runs/{target}/train.tar`, the default-schedule runs as `microlad_runs/{target}_pub/`), |
| and baseline material (`baselines/DimExDAM_gb10/data/bthr/{x,y,z}.tar`, |
| `baselines/TPDM/dataset_sample/AAPM_256_CUBE_SCLIP_XY_L067.tar`). |
| - Every tar is a plain `tar cf` archive named after the folder it replaces; its member list (size and path) is the `.tar.txt` |
| next to it. Untar inside the folder that contains the tar. |
| - Added on 2026-11-03: the 100-epoch SliceGAN runs on bfEstaillades and bfPortland, which finished on 2026-11-02 (generators |
| with the epoch-98 and epoch-99 copies, training logs, and the T-protocol pools `*_sgoff100_s0_ep{98,99,100}T*`). |
| - Not included: LaTeX build products. |
|
|
| Pools are stored as `int8` or `float16` arrays of shape (volumes, 64, 64, 64) with +1 pore and -1 solid. The selection rule |
| of each release, the registered experiments that produced every file and all result tables are in `method_log.md` of the |
| GitHub repository. |
