fit_spline_curve — 3D curve op

• Data kinds: points → points

• Call: import curve3d; curve3d.fit_spline_curve(points, smooth=0.0, k=3, n=None) (or ops3d.get("fit_spline_curve"))

Usage

Smooth and resample an ordered 3-D point sequence with a B-spline. → (M,3). For smoothing noisy trajectories and edges.

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