fit_bspline_surface — 3D freeform op

• Data kinds: image2d × image2d × image2d → bspline_surface

• Call: import bspline_surf; bspline_surf.fit_bspline_surface(x, y, z, kx=3, ky=3, smooth=None) (or ops3d.get("fit_bspline_surface"))

Usage

Least-squares fit a bicubic (default) B-spline surface to scattered (x, y, z) (bisplrep).

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

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

Runnable examples (verified samples that actually call this op)

• bspline_freeform — py -3.11 examples_3d/bspline_freeform.py

Ops the type connects to (they accept bspline_surface as input)
