Aliasing
Overview
In gaming, aliasing refers to the jagged edges that appear on objects when the game is rendered at a lower resolution than the display. This is because the pixels on the display are not able to perfectly represent the smooth curves of the object.
There are a number of different anti-aliasing techniques that can be used to reduce aliasing. Some common techniques include:
-
Multi-sampling anti-aliasing (MSAA): MSAA works by rendering the scene multiple times at different resolutions and then averaging the results. This creates a smoother image with less aliasing.
-
Temporal anti-aliasing (TAA): TAA works by taking advantage of the fact that frames in a video game are typically rendered in sequence. TAA compares the current frame to previous frames and then uses this information to smooth out the edges of objects.
-
Fast approximate anti-aliasing (FXAA): FXAA is a fast and simple anti-aliasing technique that works by blurring the edges of objects. FXAA is not as effective as other anti-aliasing techniques, but it is less demanding on the GPU.
The best anti-aliasing technique for a particular game will depend on a number of factors, including the game’s graphics settings, the player’s hardware, and the player’s personal preference.
