fit_superquadric — 3D `superquadric` op

• Data kinds: points → primitive

• Call: import fullseye as fs; fs.ledger.fit_superquadric(points) -> 'dict' (to call the implementation directly, import superquadric; superquadric.fit_superquadric(points) -> 'dict'; from the registry, ops3d.get("fit_superquadric"))

Usage

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

> The detailed description below is the original text — the summary and the headings are translated.

初期姿勢 = 慣性テンソル固有ベクトル、初期 a = 主軸 bbox 半分、初期 eps=(1,1)。

`a は正、eps` は [0.1, 2.0] にクリップして最適化する。

Returns

-------

dict: {'a': (3,), 'eps': (2,), 'R': (3,3), 't': (3,), 'residual': float}
