distance_point_line — 3D `geometry` op

• Data kinds: points × primitive → measurement

• Call: import fullseye as fs; fs.ledger.distance_point_line(p, line_pt, d) (to call the implementation directly, import match3d; match3d.distance_point_line(p, line_pt, d); from the registry, ops3d.get("distance_point_line"))

Usage

Point-to-line distance.

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

`w = p − line_pt の、方向 d̂ に直交する成分の長さ |w − (w·d̂)d̂|` を float で返す

(`d は内部で単位化。2-D/3-D 共通)。p, line_pt, d` は数値の 2 または 3 ベクトル、

次元の混在は ValueError。`d が零ベクトルなら |w|` がそのまま返る。単位は入力座標の単位。

用途: `fit_line_3d の軸からの偏心、line_from_2points` の線に対する点群のばらつき

(1 点ずつ)。
