SMAA: Subpixel Morphological Antialiasing ========================================= SMAA is a very efficient GPU-based MLAA implementation (DX9, DX10, DX11 and OpenGL), capable of handling subpixel features seamlessly, and featuring an improved and advanced pattern detection & handling mechanism. The technique focuses on handling each pattern in a very specific way (via look-up-tables), in order to minimize false positives in the pattern detection. **Ultimately, this prevents antialiasing features that are not produced by jaggies, like texture details**. Furthermore, this conservative morphological approach, together with correct subsample area estimation, allows to accurately combine MLAA with multi/supersampling techniques. Finally, the technique has been specifically designed to clone (to a reasonable extent) multisampling reference results.

Usage ----- See [SMAA.hlsl](https://github.com/iryoku/smaa/blob/master/SMAA.hlsl) for integration info (despite the extension, note that it's OpenGL compatible). You'll also need some precomputed textures, which can be found as C++ headers ([Textures/AreaTex.h](https://github.com/iryoku/smaa/blob/master/Textures/AreaTex.h) and [Textures/SearchTex.h](https://github.com/iryoku/smaa/blob/master/Textures/SearchTex.h)), or as regular DDS files (see [Textures](https://github.com/iryoku/smaa/blob/master/Textures) directory). If you want to see where they came from, you can check out the [Scripts](https://github.com/iryoku/smaa/blob/master/Scripts) directory. The directories [DX9](https://github.com/iryoku/smaa/blob/master/Demo/DX9) and [DX10](https://github.com/iryoku/smaa/blob/master/Demo/DX10) contain integration examples for DirectX 9 and 10 respectively.
