Gallium3D Post-Processing, MLAA Nearly Ready

[curaga]

The updated source has not been released yet. 1.6 also changed the name, it's called SMAA (Subpixel Morphological AA).

Good grief... Just what we need.. Yet another name for Anti-aliasing tech to confuse the gamers....

Let's see...

FSAA (full scene)
MSAA (multi-sample)
SSAA (super sample)
TrAA (transparency / alpha texture)
CSAA (Coverage sample)
AdAA (Adaptive)
FXAA ( Effects )
MLAA (MorphoLogical)

and now we've got...

SMAA (Subpixel Morphological)

It's not too bad when you realize they come in families:

fsaa = ssaa.

traa, csaa, adaa are just vendor-tweaked msaa.

You've missed a few, such as GPAA, GBAA and a couple of others. No, I'm not kidding.

You can add eqaa == csaa to the list.

Edit: Oh and unless there's another another FXAA, it stands for Fast approXimate AA and == SMAA, pretty much.

I wouldn't equate FXAA with SMAA, even the current MLAA beats FXAA in my opinion. Though they are similar in both being post-processing approaches.

In quality, maybe. It's kind of subjective, but I'd declare FXAA and MLAA a draw.

In performance Nvidia's FXAA implementation wins AMD's MLAA (on Windows) quite clearly.

Edit: Oh, and I equated FXAA with SMAA instead of MLAA, because unlike MLAA it also uses a subpixel approach.

Good to know! I found some more info here: http://www.iryoku.com/introducing-su...l-antialiasing

That is not hard to do, Jimenez' MLAA beats AMD's by a factor of 7-8x in speed, while also beating it in quality. Though this was measured before 11.8 which claims to have sped up AMD's MLAA.

PP is now available in Mesa master.
