render op• Data kinds: normalmap → image2d
• Call: import fullseye as fs; fs.ledger.render_shaded(normals_img, light=(0, 0, 1), ambient=0.1) (to call the implementation directly, import match3d; match3d.render_shaded(normals_img, light=(0, 0, 1), ambient=0.1); from the registry, ops3d.get("render_shaded"))
Normal map (H,W,3) + light direction → a Lambertian shaded image (appearance-sample generation, the bridge to optics).
> The detailed description below is the original text — the summary and the headings are translated.
`I = ambient + (1 − ambient)·clip(n·L̂, 0, 1) を (H, W)` float64、値域 [0, 1] で返す。
`light` は内部で単位化する(零ベクトルは 0 除算で NaN)が、法線は単位化しない(単位法線を
渡す。`estimate_point_normals / normals_from_depth` の出力は単位)。法線の成分順と
`light の成分順は揃える(既定 (0,0,1)` は第 3 成分=カメラ向きを正面光とする規約)。
光源と反対を向く面は `ambient の値になる。最後の軸を法線とみなすので (N,3)` の点ごとの
法線でも動く。鏡面ハイライトは無い(`fresnel_reflectance / reflect` で別途)。
用途: `photometric_stereo` の検算(法線 → 画像の順方向)、外観検査の合成サンプル。
