In 3D graphics
Anisotropic Filtering,
abbreviated as AF, is a technique used to improve image quality in
computer video games. AF enhances the
textures on surfaces that are far away and at high
angles (sloped relative to the camera view) so that the projection of the
texture appears more like a rectangle or trapezoid than a square. When AF is
applied to the sloped texture, the surface does not appear fuzzy to the viewer.
Anisotropic Filtering is a feature found on most 3D
video cards today, however card manufacturers do not necessarily use the
same process to
render AF.
