fit_plane3 — 3D geometry op

• Data kinds: points → primitive

• Call: import fullseye as fs; fs.ledger.fit_plane3(points) -> 'dict' (to call the implementation directly, import measure3d; measure3d.fit_plane3(points) -> 'dict'; from the registry, ops3d.get("fit_plane3"))

Usage

Least-squares 3-D plane fit to `(depth, row, col)` points — the plane

through the centroid whose normal is the smallest principal axis (minimises the

sum of squared point-to-plane distances). Returns `center (cd/cr/cc`), a

unit `normal` (depth, row, col), and the RMS point-to-plane residual. Raises

`ValueError` on < 3 points or a collinear set (the normal is undefined).

• Operator provenance and references — the sources of the research/methods this op family came from.
