Blue noise textures are useful for providing per-pixel random values to make noise patterns in renderings. Blue noise textures are harder to see and easier to remove than noise made by either random number generators or hashes, both being white noise. To use a blue noise texture, you tile it across the screen, read the texture with nearest neighbor point sampling, and use that as your random value.
