Anti Aliasing

Anti-aliasing is a technique used in computer graphics to smooth out the jagged edges of objects and lines that are displayed on a screen. The jagged edges, also known as "jaggies," are caused by the limited resolution and pixel density of a screen or image.

Anti-aliasing works by blending the edges of objects or lines with the surrounding pixels, creating a smoother and more natural appearance. This is achieved by adding additional pixels in between the object or line and its background, and by using shades of colors to blend the edges together.

There are several types of anti-aliasing techniques, including multisample anti-aliasing, supersample anti-aliasing, and temporal anti-aliasing. These techniques differ in the way they sample and blend the pixels to create a smoother image.

Anti-aliasing is commonly used in video games, computer-generated animations, and graphic design to create high-quality, smooth images and visuals. However, it can also increase the computational cost of rendering an image, and may not always be necessary or practical depending on the application.
