What Wikipedia says

In 3D computer graphics, anisotropic filtering (AF) is a technique that improves the appearance of textures, especially on surfaces viewed at sharp angles. It helps make textures look sharper and more detailed by reducing blur and aliasing that can occur when surfaces are angled away from the viewer.
