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"))
Draws black disk markers (centers pts (N, 2) [px], radius r_px) on RGB (H, W, 3): rgb *= 1 − dark·coverage using pixel coverage. Coverage is supersampled sub² only for pixels on the disk edge (1 inside, 0 outside). The image is not warped by interpolation, so the ground truth is exact. Raises ValueError: rgb is not (H, W, 3), pts is not (N, 2), r_px ≤ 0, dark outside [0, 1].
