mesh_reduction_report — 3D `resolution` op

• 資料種類:mesh × mesh → table

• 呼叫: import fullseye as fs; fs.ledger.mesh_reduction_report(V, F, V2, F2, samples=4000, seed=0, detail_quantile=0.9)(要直接呼叫實作,import meshres; meshres.mesh_reduction_report(V, F, V2, F2, samples=4000, seed=0, detail_quantile=0.9);從台帳取用則 ops3d.get("mesh_reduction_report"))

用法

一次削減(簡化・重網格化・體素化)失去了什麼,以數字給出(`table`)。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

Samples *samples* area-weighted points of the original surface, measures

their distance to the reduced surface (`rms_error, max_error`, and

`p99_error`), and does the same for the subset of original points that

lie in the top `1 − detail_quantile of :func:mesh_detail_map`'s

`detail (detail_rms_error / detail_max_error`): the

high-curvature places — a crater rim, a boulder, an outlier ridge — are

exactly where a discovery hides and where a quadric decimation flattens

first. Also `face_ratio, area_change and volume_change`

(signed, closed meshes). A reduction whose `detail_max_error` is larger

than the feature you are looking for has already lost it.
