How does bridging work without breaking the shape?
For every isolated island (kept material fully surrounded by cut area), the tool casts a ray outward from points around its edge until it exits the cut region, then paints that strip back to material directly in the mask before re-tracing — so the fix happens in raster space, which sidesteps needing to synchronize gaps across two separate contours.
Why multiple layers?
A single silhouette loses all tonal detail. Cutting several layers, each covering a wider tone range, lets you spray progressively lighter or darker paint through each one and build up a photorealistic image.
What if a bridge looks wrong on a tiny detail?
Increase the bridge spacing or width, or reduce the layer count — fewer, larger islands are easier to bridge cleanly.
What materials work?
Manila stencil paper, chipboard, and mylar sheets for hand cutting; thin plywood, cardboard, or vinyl for laser/knife cutters.
