tb_pc_poisson_disk — 2D typed op

• 資料種類:points → points

• 呼叫:fullseye.apply(img, "tb_pc_poisson_disk", a=0.5, b=0.5)(2-D 的模型是一張圖 + 兩個純量旋鈕 a,b∈[0,1])

*無圖: 該運算子以 points 為輸入。從影像開始的 Studio 程式無法到達該型別，請參見下方的可執行範例。*

用法

藍雜訊稀疏化:貪婪地保留點,使任兩點間距離不小於 *radius*(`points`)。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

Points are visited in a seeded random order; a point is kept if no kept

point lies within *radius* (cKDTree ball query). Dense regions are thinned

to the radius, sparse regions (spacing already > radius) are kept whole —

unlike a voxel grid, which also moves points to cell centroids.

Typed bridge of the 3d op `pc_poisson_disk into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.
