heap_synth_cone — DRIVE `granular` op

• Data kinds: scalar × scalar → table

• Call: import fullseye as fs; fs.ledger.heap_synth_cone(phi_deg: 'float', radius_px: 'float', pitch: 'float' = 0.001, *, toe_round_px: 'float' = 0.0, apex_blunt_px: 'float' = 0.0, ground_tilt_deg: 'float' = 0.0, margin_px: 'int' = 12, supersample: 'int' = 8, noise: 'float' = 0.0, seed: 'int | None' = None) -> 'dict' (to call the implementation directly, import granular; granular.heap_synth_cone(phi_deg: 'float', radius_px: 'float', pitch: 'float' = 0.001, *, toe_round_px: 'float' = 0.0, apex_blunt_px: 'float' = 0.0, ground_tilt_deg: 'float' = 0.0, margin_px: 'int' = 12, supersample: 'int' = 8, noise: 'float' = 0.0, seed: 'int | None' = None) -> 'dict'; from the registry, opsdrive.get("heap_synth_cone"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

既知の安息角の円錐の山を合成する(側面像 = 反エイリアスの被覆率、高さ図 = セル中心の高さ)。

• `radius_px: 裾までの半径 [px] (丸み無しのとき)。高さ H = R tan φ`。

• `ground_tilt_deg: **基準面の傾き**(せん断型: z' = z + x tan β`)。高さ図の基準面(datum)

が傾いているときの罠(平らでない地面で安息角が足し算される —— 既存 PoC poc_stockpile_volume

と同じ門)。カメラのロール(回転型)とは 2 次でなく 1 次で違う(β = 5 度・φ = 30 度で

1.4 度、`atan(tan φ + tan β) 対 φ + β`)ので別物として扱う。

• `noise`: 被覆率に足す一様雑音の振幅(縁の揺らぎの代わり)。

• 返り: `side(被覆率 (rows, cols))、heightmap [m]、ground`(基準面 [m]、同形)、

`truth`(phi_deg, R_px, H_px, toe_px, V(数値回転積分 [m³]), V_cone(閉形式)、ground_tilt_deg)、

`pitch。側面像の列 x の粉の高さ(被覆率の列和)はちょうど c(x)` [px] になる(副画素)。

Raises `ValueError`: 範囲外・円弧の重なり。
