Fast Approximate Anti-Aliasing (FXAA)

Fast Approximate Anti-Aliasing (FXAA) is a technique used in digital graphics to smooth out jagged edges, known as aliasing, in images and videos. Instead of re-rendering the entire scene at a higher quality, FXAA quickly analyzes the image after it's drawn and applies a subtle blur to harsh edges. This process makes lines and details appear softer and more natural without significantly impacting performance. FXAA is popular because it provides a good balance between visual quality and speed, improving image smoothness in real-time applications like video games without major hardware demands.
