superquadric_residual — 3D superquadric op

• Data kinds: points → measurement

• Call: import superquadric; superquadric.superquadric_residual(points, a, eps, R, t) -> 'float' (or ops3d.get("superquadric_residual"))

Usage

The Gross-Boult volume-corrected residual mean((sqrt(a1 a2 a3)(F^eps1 − 1))²).
