  1. The Jump Flooding Algorithm can be used to generate distance fields around textures for various effects like outlines, shadows, and glows.
  2. The algorithm involves multiple passes sampling a 3x3 area at varying scales, focusing on opaque pixels and empty space.
  3. You can make variations to the algorithm based on your needs, like using floating-point surfaces for a greater distance range or calculating the internal distance for a proper SDF.
