tb_farthest_point_sampling — 2D `typed` op

• Data kinds: points → signal

• Call: fullseye.apply(img, "tb_farthest_point_sampling", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

*No figure: this op takes points as input. A Studio program starting from an image cannot reach that type — see the runnable examples below for how it is used.*

Usage

Farthest point sampling based on geodesic distance (even thinning). → an array of selected indices (n,) int.

2-D 進化レジストリへ橋渡しした 3d の op `farthest_point_sampling。実装は同じで、呼び出し規約だけ op(v, a, b) に合わせてある。a が k(既定 8)を振る。b` は未使用。
