In this type of technique, a scene is rendered to an off screen surface and processed with anti-aliasing algorithms. The process output is split up on the on screen surface. This type of anti-aliasing includes AMD's Morphological Filtering (MLAA), Fast Approximate Anti-aliasing (FXAA), Subpixel Morphological Anti-aliasing (SMAA), and so on.
In this, we will discuss the various post processing techniques mentioned earlier.
Fast Approximate Anti-aliasing (FXAA): FXAA is a post-processing filtering technique. This filter primarily does two things: it first detects edges and then applies the blurring algorithm to aliased edges. Like previous techniques, which are hardware dependent, FXAA can be highly useful for cases where anti-aliasing options are limited. FXAA gives very good performance. It's faster compared to MSAA and SSAA, making it a preferred choice for the gaming industry. This technique works in the image space. Therefore, it...
