sample_surface — 3D superquadric op

• Data kinds: vector → points

• Call: import superquadric; superquadric.sample_surface(a, eps, n_u: 'int' = 40, n_v: 'int' = 40, R=None, t=None) -> 'np.ndarray' (or ops3d.get("sample_surface"))

Usage

Sample the surface points of a superquadric parametrically in (eta, omega).

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