Hi MLAA looks fantastic and can solve some issues like no hardware AA support on DX9 when using deferred shading. I what to create a post processing shader but i have some problems to understand these technique, so any discussion, help, hint or code are welcome.

You can download the source-code from here:

Be aware though that this technique was designed for CPUs or compute-shaders on GPUs.

"Metro 2033" call it "Analytical Antialising"

Analytical AA resolves coverage mathematically, without resorting to sampling. No game does analytical antialiasing, so whoever is making that claim doesn't know what they're talking about.

@Hodgman
Well i know the source code, but to read an SSE and compute shader optimised source makes it not easier to understand.

What i want to do is a "normal" post shader and realize how it works.

The edge detecting is not that problem but how to calculate slope/weight even more.

@Christer Ericson
Thanks for that info, maybe AAA sounds better than MLAA :D
