• Call: import fullseye as fs; fs.ledger.cone_profile_px(u, H_px: 'float', phi_deg: 'float', toe_round_px: 'float' = 0.0, apex_blunt_px: 'float' = 0.0) (to call the implementation directly, import granular; granular.cone_profile_px(u, H_px: 'float', phi_deg: 'float', toe_round_px: 'float' = 0.0, apex_blunt_px: 'float' = 0.0); from the registry, opsdrive.get("cone_profile_px"))
Cross-section c(u) [px] of the cone's generatrix (u = distance from the axis [px]).

基本は c = max(0, H − u tan φ)。apex_blunt_px = 頂に内接する円弧の半径(材料を削る、中心は (0, H − r/cos φ)、接点 u = r sin φ)。toe_round_px = 裾の凹みを埋める円弧の半径(材料を足す、中心は空気側 (x_t, r)、x_t = R + r tan(φ/2)、接点 u = x_t − r sin φ)—— どちらも接線連続(導出: 接点で両側の高さが裾は r(1 − cos φ)、頂は H − r sin²φ / cos φ で一致)。Raises ValueError: 2 つの円弧が重なる(山が小さすぎる)。
