| # Codex-generated Blender street scenes (WebDataset) |
|
|
| Procedural Blender 5.0 reconstructions of 5 street-view reference photos, each written by an OpenAI codex agent (`codex exec`, reasoning effort `xhigh`) as a single `scene.py`. |
|
|
| | dir | model | prompt | |
| |---|---|---| |
| | `blender/` | gpt-6.1-sol | v1 (no label requirement) | |
| | `blender_astra/` | gpt-6-astra | v2 (`jobs/prompt_blender.md`: fixed outputs, semantic `label` property on every object, realism) | |
|
|
| ## Format |
| One tar shard per run (`<run>/<run>-000000.tar`), one sample per scene. Sample key = scene name, e.g. `03_europe_historic_facades`. Members (`<key>.<file>`, nested paths flattened with `_`): |
|
|
| - `meta.json` – run, model, effort, timing, token stats, file list |
| - `scene.py` – generator script (`blender -b --factory-startup -P scene.py` rebuilds `scene.blend` + `render.png`) |
| - `scene.blend`, `render.png`, `ref.jpg` (4096 px reference), `NOTES.md`, `prompt.md` (v2 only) |
| - intermediate iteration renders / logs, `codex_events.jsonl` (full agent trace incl. token usage) |
| - `viewer_objects.json` (object table: name, label, parent, bbox, tris), `viewer_mesh.npz` (world-space triangles per label) |
|
|
| ```python |
| import webdataset as wds |
| ds = wds.WebDataset("hf://datasets/wangchenlong/temp/blender_astra/blender_astra-000000.tar") |
| for s in ds: |
| print(s["__key__"], sorted(s)) |
| ``` |
