pc_fill_sparse — 3D resolution op

• 数据种类:points → points

• 调用: import fullseye as fs; fs.ledger.pc_fill_sparse(points, spacing, k=8)(要直接调用实现,import meshres; meshres.pc_fill_sparse(points, spacing, k=8);从台账取用则 ops3d.get("pc_fill_sparse"))

用法

在局部间距超过 *spacing* 处、于局部 PCA 平面上插入点(`points`)。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

For every point whose distance to its *k*-th neighbour exceeds *spacing*,

the segments to those neighbours longer than *spacing* are subdivided at

*spacing* intervals; the new points are projected onto the plane fitted

(PCA) to the point's neighbourhood so they follow the surface rather than

cut chords across it. The original points are kept; the result is then a

cloud whose spacing is ≤ target almost everywhere (pass it to

:func:pc_poisson_disk to remove the duplicates a shared edge creates —

:func:pc_density_equalize does both).
