What Is Anisotropic Filtering (AF)?

Anisotropic filtering is like that. Looking at it superficially, it appears to be nothing. However, if you take a closer look, BAM! You'll see it. Anisotropic filtering is a technique used in 3D computer graphics in which the number of texture samples generated changes depending on the angle of the surface to be rendered relative to the camera. Anisotropic filtering makes surfaces or patterns angled and farther from the camera look better and sharper than when this filter is not applied. Anisotropic filtering improves these surfaces because they can comprise different layers of textures (like a piece of paper). Each layer will have its orientation (the direction it faces), so when you're looking at it straight-on, each layer will be perfectly aligned with all the others around it, which means all those layers will look sharp and clear. However, if you were viewing one layer from an angle where one side was facing toward you while another was facing away from you, then some parts would appear sharper than others since they're closer to where your eyes are focusing. Anisotropic filtering is the process of using multiple texture samples to create a better-looking image. It's like taking a photo with your phone. If you take a picture with your phone and then take one with an actual camera, the photos will look different because the camera uses more pixels. Anisotropic filtering is excellent for computer graphics because it helps computers render 3D models faster. Suppose you made a brick wall in 3D and wanted it to look natural. In that case, you could use anisotropic filtering to ensure each brick was perfectly formed instead of having some blurred bricks because they were made from fewer pixels. It's also helpful in making textures look more realistic!
