typed op• Data kinds: points → signal
• Call: fullseye.apply(img, "tb_env_studio", 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.*
Radiance of a studio environment (direction -> brightness). Achromatic.

ソフトボックス 2 枚 + 天空の勾配 + 細い水平の帯。色を付けないのは、金属の色が
環境ではなく Fresnel(n, k) から出ていることを絵の中で保証するため。
`directions` は (..., 3) の単位ベクトル(z 上向き)。返り値はその形の (...,)。
2-D 進化レジストリへ橋渡しした optics の op `env_studio。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 key(既定 12)、b が fill`(既定 3.2)を振る。
• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).
• Operator provenance and references — the sources of the research/methods this op family came from.
