Title: SMAA (Alternative to FXAA?)
Post by: Kolgena on December 04, 2011, 12:03:51 pm

So I came across this:
http://www.iryoku.com/smaa/
http://mrhaandi.blogspot.com/p/injectsmaa.html

It seems to be a screenspace AA technique like FXAA that is a little weaker in antialiasing, but results in much less blurring and has less of a performance impact. Right now, it looks like it's purely DX-based though, so it probably can't be easily ported to OpenGL.

Anyways, I'm bringing it up as a point for speculation rather than a feature suggestion. Since FXAA already works so well with FSO, it may be pointless to implement something that may not even work as well to anti-alias the types of aliasing most seen in FS.

Well, it's something I shall take a look at. If it is faster than fxaa, then using it shall be no problem. That said, it looks to be a somewhat more involved affair compared to fxaa's "here's a shader you need to run once over your frame" approach.

I also came across this a few minutes ago:

May be worth it to see what his FXAA update does before delving into SMAA.

Oh, shiny. I hope this update comes out soon.
