# 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

import cv2 import numpy as np from scipy import ndimage def png_to_sdf(input_path, output_path, radius=15): # 1. Load PNG as Grayscale img = cv2.imread(input_path, cv2.IMREAD_GRAYSCALE) binary = cv2.threshold(img

Raster images are great for humans looking at a screen. But for machines—especially those navigating a 3D space or rendering crisp fonts—they are notoriously inefficient. convert png to sdf
