smallest_sphere3 — 3D geometry op

• 数据种类:points → primitive

• 调用: import fullseye as fs; fs.ledger.smallest_sphere3(points) -> 'dict'(要直接调用实现,import measure3d; measure3d.smallest_sphere3(points) -> 'dict';从台账取用则 ops3d.get("smallest_sphere3"))

用法

`(depth, row, col)` 点的最小包围球(Welzl 精确解)。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

algorithm on the convex hull). Returns `center (cd/cr/cc`) and radius

`r` — the smallest sphere that contains every point. This is the 3-D

`smallest_circle`; its radius is strictly below the AABB-diagonal sphere on

any non-spherical set, and equals the true radius for points on a sphere.

Raises `ValueError` on empty input.
