pc_thinning_report — 3D resolution op

• データ種: points × points → table
• 呼び出し: import fullseye as fs; fs.ledger.pc_thinning_report(points, thinned, k=8, radius=None) (実装を直接呼ぶなら import meshres; meshres.pc_thinning_report(points, thinned, k=8, radius=None)、台帳から引くなら ops3d.get("pc_thinning_report"))

使い方

What a point-cloud thinning removed, and whether it touched the rare points (table).

removed count and fraction; removed_spacing percentiles of the local spacing (:func:pc_density) of the removed points versus kept_spacing; isolated_removed counts removed points whose nearest-neighbour distance exceeded radius (default: the 95th percentile of nearest-neighbour distances) — a thinning that removed such points has discarded exactly the rare, isolated observations a survey exists to find (:func:pc_poisson_disk with the same radius removes none of them, by construction); max_gap is the largest distance from any removed point to the kept cloud (the biggest hole the thinning made).
