texture filtering

In computer games, textures are applied to all 3D objects. When textures are viewed directionally, they appear distorted at larger viewing angles.

Texture filtering is a technique implemented in graphics processors to avoid distortion of textures at larger viewing angles. Compensation for these distortions began with bilinear filtering, which was later replaced by improved trilinear filtering.

Another filtering technique used in texture filtering is anisotropic filtering( AF), whose quality can be activated in different quality levels, similar to antialiasing.
