Anisotropic filtering

In 3D computer graphics, anisotropic filtering is a method of enhancing the image quality of objects located far away from the camera. Like bilinear and trilinear filtering it eliminates aliasing effects, but introduces less blur in the process and thus preserves more detail. Anisotropic filtering is computationally relatively expensive and has only recently become a standard feature of consumer-level graphics cards.
