Efficient antialiasing techniques are an important tool of high-quality, real-time rendering. MSAA (Multisample Antialiasing) is the standard technique in use today, but comes with some serious disadvantages:

    Incompatibility with deferred lighting, which is used more and more in real-time rendering;
    High memory and processing cost, which makes its use prohibitive on some widely available platforms (such as the Sony Playstation* PS3* [Perthuis 2010]). This cost is also directly linked to the complexity of the scene rendered;
    Inability to smooth non-geometric edges unless used in conjunction with alpha to coverage.

A new technique developed by Intel Labs called Morphological Antialiasing (MLAA) [Reshetov 2009] addresses these limitations.
