# Poster

`hermes_poster.png` (1600 × 2400) is rendered from the real enclosure model: hidden-line wireframe
of the feature edges and silhouettes, 6 mm contour slices on the shells, the flat P7 face lit on
the screen, a mirrored pass for the wet floor, then haze, bloom and CRT scanlines.

To regenerate after changing the model:

```bash
cd enclosure
for n in base servo_pan plate body yoke servo_tilt cradle camera; do
  openscad -o poster/pose/$n.stl -D "PART=\"pose_$n\"" -D '$fn=48' hermes_robot.scad
done
openscad -o /tmp/pose_info.stl -D 'PART="pose_info"' hermes_robot.scad   # prints WIN / LED coordinates
python3 poster/render_poster.py
```

If the window or LED positions change, copy the printed `WIN` and `LED` values into
`render_poster.py`. The script needs the DejaVu fonts (Debian `fonts-dejavu`, Arch `ttf-dejavu`); elsewhere, set
`POSTER_FONT_DIR` to a folder holding them. `face.png` is a frame captured from `docs/face-prototype.html` (flat shape,
P7, speaking). Requires `numpy`, `trimesh` and `Pillow`.
