 "title": "Rebuild the store in Blender and render a shopper's view",
 "page_title": "How to rebuild the store in Blender and render a shopper's view with Brandpose",
 "summary": "Calibrate the camera to marked corners, model the fixtures in Blender and render one shopper's view.",
 "who": "A 3D artist or computer vision researcher who wants to visualize tracked shopper paths inside a reconstructed store.",
 "problem": "Tracked shopper paths and gaze rays are hard to interpret as numbers alone, and the camera-to-store geometry is not obvious from the image.",
 "outcome": "A calibrated camera and fixture layout in config/, a Blender store model, and a rendered first-person view of one shopper with the side-by-side and shopper's-view videos.",
 "steps": [
  "Complete the base setup with `python3 -m venv .venv && .venv/bin/pip install -r requirements.txt` and make sure the extraction from the promo run exists.",
  "Install Blender 5.2 from https://www.blender.org.",
  "Open docs/experiments/2026-10-18-blender-pov.md at the section #rodar (in Portuguese) and run the commands listed there for calibration, modeling and rendering.",
  "Use scripts/blender/overlay.py to check that the fitted fixtures line up with the image before rendering the shopper's view with scripts/blender/pov.py."
 ],
 "agent_prompt": "Using the repo escudero/brandpose, follow docs/experiments/2026-10-18-blender-pov.md to calibrate the camera with scripts/blender/calib.py, then render the shopper's view with scripts/blender/pov.py for <person ID>. Report the output video path and the calibration result. Verify with scripts/blender/overlay.py that the fixtures match the image before accepting the render.",

 "difficulty": "Advanced",
 "time": "About 4 hours",
 "basis": "readme",
 "caveat": "The README says the shopper's view is a reconstruction, with his position off by about 20 to 30 cm, and the ceiling, storefront and products are made up.",

 "lang": "python",
 "requirements": [
  "Python 3.13",
  "FFmpeg installed and on the system",

  "A machine able to run the models; the README reports tests on a Mac M2 Pro with 16 GB using MPS acceleration",
  "Blender 5.2 only if you want the 3D store and shopper's view"
