fit_superquadric — 3D `superquadric` op

• Data kinds: points → primitive

• Call: import superquadric; superquadric.fit_superquadric(points) -> 'dict' (or ops3d.get("fit_superquadric"))

Usage

Fit a superquadric to a point set with least_squares and return dict{a, eps, R, t, residual}.

• 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.
