Images produced with single point sampling can achieve the fastest frame rate, at the expense of aliasing artifacts such as “stairsteps” and “narrow faces breakup”.
These artifacts are more noticeable in real-time (RT) CGI applications, such as when simulating visual scenes for flight training or playing computer video games.
The super-sampling anti-aliasing (SSAA) approach cannot be used in real-time applications, since it requires to compute a two-dimensional array of images.
The multisample anti-aliasing (MSAA) approach is similar to SSAA, but uses only a subset of the sample points.
The position of the subpixel sample points for MSAA can be derived from solutions to the “Eight-queens puzzle”.
