mesh_decimate_preserving — 3D resolution op

数据种类:meshtable

调用: import fullseye as fs; fs.ledger.mesh_decimate_preserving(V, F, target_faces, protect_quantile=0.8, max_error=None, samples=4000, seed=0)(要直接调用实现,import meshres; meshres.mesh_decimate_preserving(V, F, target_faces, protect_quantile=0.8, max_error=None, samples=4000, seed=0);从台账取用则 ops3d.get("mesh_decimate_preserving"))

用法

保留细节区域的简化,并报告失去了什么(`table`)。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

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"}``.
