Aliasing is a type of distortion that occurs when digitally recording high frequencies with a low sample rate. For example, in a motion picture, when a car's wheels appear to slowly spin backwards while the car is quickly moving forward you are seeing the effects of aliasing. Similarly when you try to record a frequency greater than one half of the sampling rate (the Nyquist Frequency), instead of hearing a high pitch you may hear a low frequency rumble. ...

In computer graphics, the process by which smooth curves and other lines become jagged because the resolution of the graphics device or file is not high enough to represent a smooth curve. Smoothing and antialiasing techniques can reduce the effect of aliasing.

The result of sampling an analog frequency signal at a rate below that required by the Nyquist theorem of 2 xF s . Under-sampling translates high frequency components into the pass-band, producing unwanted signal components and unpredictable results.

This topic was covered in a previous Tech Tip related to digital cameras, and the concept is the same as it applies to gaming graphics. Aliasing is basically described as the tendency for a curved or diagonal line to appear jagged since they are composed of tiny squares, or pixels. Anti-aliasing remedies this jagged appearance through software, making images appear more smooth and natural. ...
