pc_density — 3D resolution op

使い方

Local spacing per point and the cloud’s non-uniformity (table).

spacing (N,) = distance to the k-th nearest neighbour; mean_nn (N,) = mean distance to the k neighbours; stats percentiles of both; nonuniformity = p95/p5 of spacing (1 = uniform; a regular grid gives exactly 1 and spacing = pitch·√k-shell); surface_density (N,) = k / (π·spacing²) assuming a surface-like cloud.
