mesh_decimate_preserving — 3D `resolution` op

• 資料種類:mesh → table

• 呼叫: import fullseye as fs; fs.ledger.mesh_decimate_preserving(V, F, target_faces, protect_quantile=0.8, max_error=None, samples=4000, seed=0)(要直接呼叫實作,import meshres; meshres.mesh_decimate_preserving(V, F, target_faces, protect_quantile=0.8, max_error=None, samples=4000, seed=0);從台帳取用則 ops3d.get("mesh_decimate_preserving"))

用法

保留細節區域的簡化,並回報失去了什麼(`table`)。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

Vertices whose :func:mesh_detail_map `detail` is in the top

`1 − protect_quantile are **protected**: :func:meshrepair.decimate_qem`

never collapses an edge that touches them, so a crater rim, a boulder or

an outlier ridge keeps its exact geometry while the smooth remainder is

reduced toward *target_faces*. The result carries the

:func:mesh_reduction_report; when *max_error* (mesh units) is given and

the measured `detail_max_error` exceeds it, the op refuses

(`ValueError`) instead of returning a mesh that has already lost the

features you protect. Returns ``{"V", "F", "report", "protected_vertices",

"protected_mask", "detail_threshold"}``.
