Convert Png To: Sdf

# 2. Normalize to binary (0 or 255) _, binary = cv2.threshold(img, 127, 255, cv2.THRESH_BINARY)

Is your shape black on white or white on black? SDFs care about sign . If your output looks like a bump instead of a cavity, invert the image before processing. convert png to sdf

# 6. Normalize SDF to 0-255 range for storage sdf_normalized = (dt / dt.max()) * 255 sdf_normalized = sdf_normalized.astype(np.uint8) binary = cv2.threshold(img
