La profondeur de la scène est estimée à partir de la photo (MiDaS small ou Depth Anything V2 Small) et mélangée aux gris : les planches suivent les volumes du sujet plutôt que ses lumières et ses ombres. - Onglet « Profondeur » : part de la carte de profondeur, modèle, et détails fins de la photo gravés dans la profondeur (yeux, bouche). - Répartition des niveaux : rapproche les planches d'aires égales quand les valeurs sont tassées sur quelques gris. - Images 16 bits lues sur toute leur plage (elles étaient écrêtées à 255). - Le Python d'Inkscape (MinGW, sans pip) ne peut pas charger onnxruntime : le calcul tourne dans un environnement à part, installé par deploy.ps1 -Depth, lancé en sous-processus, résultat gardé en cache. - Depth Anything sur la carte graphique (DirectML) avec repli sur le processeur ; MiDaS small toujours sur le processeur, DirectML lui faisant rendre une carte fausse.

The image is smoothed, then split into the requested number of gray levels with evenly spaced thresholds. Each level becomes one closed path that follows the edge of its flat area, like a contour line on a map.
|
|
|
|
Each gray level goes into its own layer, named Board no. 1, Board no. 2... from the back to the front, added above the image: as many new layers as gray levels. The boards are meant to be cut and stacked: board no. 1 covers the whole image and each following board is smaller and lies in front of the previous one, lightest (or darkest) in front. In each layer, the cut outline of the board is drawn in the cut color (red), and the outline of the next board is carried over in the marking color (black), to show where to glue it. With "Its own gray only", a board holds the flat area of its gray alone: the boards sit side by side without overlapping and carry no marking. Several selected images share the same layers.
|
|
|
|
For a relief that follows the real volumes of a portrait rather than its light and shadows, raise the depth map share (Depth tab): at 100, the boards follow the volumes, and the fine details setting carves the eyes and the mouth into them. A depth map made elsewhere (8 or 16 bits) can also be imported and selected like any image, with a share of 0. In both cases, if most boards come out empty or the subject only gets a few of them, raise the level distribution.
|
|
|
|
For laser cutting, choose no fill: only the cut and marking strokes remain. For line art only, choose a white single-color fill, or no fill, with a black stroke and no marking. If the outlines are too busy, raise the smoothing or the smallest island; if they look angular, raise the smoothing or the simplification. If a face is no longer recognizable, lower the smoothing and keep "Preserve edges" checked.</label>
