intersect_line_plane — 3D geometry op

Data kinds: primitiveposition

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

Usage

Line ∩ plane → a point (None when they are parallel).

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

`t = ((plane_pt − line_pt)·n̂)/(d·n̂)line_pt + t·d を返す(float 配列)。d` は単位化

しない(`td の長さ単位)。|d·n̂| < 1e-9` なら None(例外ではない。返り値を使う

前に None チェック)。面に含まれる直線(距離 0 かつ平行)も None。引数は数値の 2 または 3

ベクトル、次元の混在は ValueError。2-D では `n` を直線の法線として線と線の交点になる。

用途: 視線(`depth_to_points の点 − 原点)と fit_plane_3d` の面との交点、レイと基準面。
