Mod

Generally unofficial, fan-made software designed to improve upon an existing game. Mods can range in size from graphical exploits to entirely new storylines or game worlds, but they are not standalone software and require the user to possess the original game to use them. Sometimes the original developer will release mods, or modding tools.

Terminology

Abbreviations/Synonyms

A form of image distortion that occurs on the outline of objects when representing a high resolution image at a lower resolution; common in 3D imaging.
|
|
Anti-Aliasing

AA

Texture Filtering
Terminology
|
Abbreviations/Synonyms
|
Definition
|
Example
|
Anisotropic Filtering
|
AF
|
A form of texture filtering that enhances the image quality of textures that recede into the distance, preventing otherwise blurred environments from impacting on graphical quality. It also eliminates aliasing, and is generally more effective than bilinear and trilinear forms of filtering at reducing blur and preserving detail.
|
|
Bilinear Filtering
|
|
A method of filtering used to smooth textures when displayed larger or smaller than their native resolution.
|
|
Trilinear Filtering
|
|
An extension of Bilinear filtering which is more accurate at smoothing images which have been resized above double their original size, or below half their original size.
