surface_form_error — 3D surface_fit op

Data kinds: image2dmeasurement

Call: import match3d; match3d.surface_form_error(height, degree=1) (or ops3d.get("surface_form_error"))

Usage

Height-field grid → the residual from an ideal (polynomial) surface = the form error (flatness deg 1 / sphericity deg 2). → (residual, rms, pv).
