radiosity opなし → table(引数だけで決まる op —— 画像やデータの入力を取らない)import fullseye as fs; fs.ledger.radiosity_patches(polygons=None, albedo=None, scene=None, patch_mm=2.0, outer_mm=None) (実装を直接呼ぶなら import radiosity3d; radiosity3d.radiosity_patches(polygons=None, albedo=None, scene=None, patch_mm=2.0, outer_mm=None)、台帳から引くなら opsoptics.get("radiosity_patches"))Build a set of flat radiosity patches (rad_patches table) from polygons or from an optscene scene.
Either polygons — (N, 3|4, 3) flat convex triangles or quads, one patch each,
vertices in order around the edge, normal = right-hand rule (the side that emits) —
with albedo a scalar, (N,) or (N, 3) (RGB) in [0, 1] (None = 0.5); or scene —
an optscene scene (scene_box, scene_difference of a box minus a box, finite
scene_plane; an infinite plane only with albedo 0) whose Lambertian faces are cut
into rectangles no larger than patch_mm (cut also at every other face’s plane, so
no patch straddles another face; outer_mm, when given, is the size used on every face
that is not the inside of a pocket — the outside of a part rarely exchanges light with
anything, so it can be coarse)
no patch straddles another face). Faces in contact with another solid are dropped.
Albedo then comes from each primitive’s material (passing albedo too is refused —
two sources for one number).
Returns a dict (table) with kind = "rad_patches", polygons (N, 4, 3),
normals (N, 3), areas (N,), centers (N, 3), albedo (N, 3),
labels (N,) (scene index, or -1), regions (N,) ("outer" / "cavity" /
"plane" / "polygon") and occluders (the scene, or None).
Raises ValueError: both or neither of polygons / scene (an empty polygon
array or scene included); albedo given with scene; a polygon that is degenerate, non-planar or non-convex; an albedo outside [0, 1] or of the
wrong shape; a scene primitive that is not supported (sphere, cylinder, nested
difference, reflective infinite plane) or not Lambertian; more than 6000 patches.
optics の全 op は入力を検証してから計算する(黙って通さない):
_mm / _um / _deg / _mrad。mm と µm の取り違えは crash ではなく「もっともらしく間違った答え」なので、名前で防ぐ。大きさから単位を推測する処理は一切しない。ValueError — float('50') は成功してしまうため、未パースの設定値が長さとして通り抜ける(実測: thin_lens('50', '200') がもっともらしい 66.667 mm を返していた)。bool も True == 1 の暗黙昇格として拒否。ValueError(実数枠のみ。虚部の無言切り捨て・マスク剥がしを拒否)。NaN/Inf は全入力で ValueError。depth_of_field の過焦点距離以遠の far_mm = inf(それが過焦点距離の定義)と gaussian_beam のウエストでの wavefront_radius_mm = inf(平面波面の曲率半径)。どちらも有限の相棒(far_is_infinite / curvature_per_mm)を併せて返す。それ以外の無言 NaN/Inf は内部で検出して ValueError —「float64 が溢れた」と「答えが無限大」は別の主張なので、後者の顔で前者を返さない。optics.MAX_GRID(4096)、供給された場/PSF/開口は optics.MAX_FIELD_ELEMENTS(2^24)、ABCD 素子列は optics.MAX_SYSTEM_ELEMENTS(1024)、Zernike は MAX_ZERNIKE_TERMS(512)/ MAX_ZERNIKE_ORDER(40)/ MAX_ZERNIKE_BASIS(2^25)。小さな引数から巨大な内部確保が起きる経路(実測: n_max=40 × 4096² で 108 GB)を fail-closed で塞ぐ。| 物理的に不可能な状態も拒否: 偏光度 > 1 の Stokes ベクトル、負の透過率、負の強度、n- | m | が奇数などの不正な Zernike 添字。 |
