fit_bspline_curve — 3D freeform op

• Data kinds: points → bspline_curve

• Call: import bspline_surf; bspline_surf.fit_bspline_curve(points, smooth=0.0, k=3, nest=None) (or ops3d.get("fit_bspline_curve"))

Usage

Fit a B-spline curve to an ordered point sequence (M,D) (splprep, parametric).

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