fit_sphere3 — 3D geometry op

使い方

Algebraic (Kåsa) least-squares sphere fit to (depth, row, col) points:

solve |P|^2 = 2 P·c + (r^2 - |c|^2) in the least-squares sense — exact for points on a sphere, a standard robust estimator under moderate noise. Returns center (cd/cr/cc), radius r, and the RMS radial residual. Raises ValueError on < 4 points or a coplanar set (no finite sphere).
