Anti-Aliasing
A method used to better define higher resolution objects in lower resolution. For example, you would use anti-aliasing if you have two lines that are so close together that at 320×200 they look as if they are one double-width line and you want to represent them better.
This is most noticeable when dealing with curves, such as circles. For example, if you look at a circle drawn in a simple paint program at a low resolution, you can see the “steps,” or “jaggies”–the points it takes to make the circle. If you raise the resolution you’ll notice the “steps” much less. If you use anti-aliasing, different shades of the circle’s color are used to “fill in” the gaps caused by low resolution, smoothing out its appearance to the user.
Typical uses for anti-aliasing are for smoothing out fonts and straight lines in 3D images. If you are using a system with jagged-looking fonts, chances are that it’s not anti-aliasing the fonts.
