membrane_render_markers — DRIVE tacslip op

• Data kinds: rgb × matrix × scalar × scalar → rgb

• Call: import fullseye as fs; fs.ledger.membrane_render_markers(rgb, pts, r_px: 'float', dark: 'float', sub: 'int' = 8) -> 'np.ndarray' (to call the implementation directly, import tacslip; tacslip.membrane_render_markers(rgb, pts, r_px: 'float', dark: 'float', sub: 'int' = 8) -> 'np.ndarray'; from the registry, opsdrive.get("membrane_render_markers"))

Usage

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

RGB (H, W, 3) に黒い円盤のマーカー(中心 pts (N, 2) [px]、半径 r_px)を描く: 画素の被覆率で rgb *= 1 − dark·coverage。

被覆率は円盤の縁の画素だけ sub² の副標本(内側 1・外側 0)。像を補間して歪めないので真値が厳密。

Raises ValueError: rgb が (H, W, 3) でない、pts が (N, 2) でない、r_px ≤ 0、dark が [0, 1] の外。
