200,000 points (seed 0), up (0, 0, 1), fcp defaults; 40 parts, 22 fit cuts
(14 where the mesh encoding does not cut, marked *). Each cut: the layer below and the layer above,
canonical frame (x right, y up), zoomed on the cut track's rings. Black: GT, the exact section of the mesh at the layer centre.
Grey: the points within half a layer of the plane. Coloured: the point slicer's rings (red: the part below the cut, blue: the
part above, yellow: other rings; dashed: holes). Generated 2026-10-27 21:37 by scripts/splits.py.
Zoom: layer 82 (cut 16, above)
The tracked ring follows GT closely but has small hooks and spikes (vertices every ~half spacing); next to it, small extra rings sit one or two spacings off the surface. They are below the area threshold, so tracking drops them, but they and the hooks are what the slicer adds on top of GT.
