The different is not exactly noticeable... especially in the video.
of course not, since the vid itself is already in a downscaled format. for using also PP shaders you can use the FSAA plugin in resources which can be really slow for longer pp-chains. That's interesting. I'll try to implement that. let us know when it succeeds

Okay, in principle I was finished two weeks ago but I'm incredibly busy these weeks. Here is what I got so far: 45°-angles seem to be smoothed quite well. high contrast edges are smoothed better than low contrast ones; also, non-45° edges are somewhat ragged. also note the weird artifacts. again, weird artifacts, but it does look smoother. The good news is, it works! It is extremely cheap on resources (render time some miliseconds on a GF 8600m GT) and independent of scene complexity. I have to work on the artifacts, though, and I'm still curious on other implementations. It all depends on the edge detection algorithm you use, propagation and composition is quite straightforward.

Hey rojart, thanks for your comment. I emptied my inbox. What I'm really interested in is this approach: http://www.iryokufx.com/mlaa/the results are way better than mine. But I find no technical paper describing their technique. You'll get a demo of it when it's working properly. Joey. edit: the shaders are in GLSL, so you'd have to convert them anyway.

But I find no technical paper describing their technique. That is maybe because it will appear in the "GPU Pro 2" book which is apparently not on sale yet.

Afaik, it is a different series at a different publishing company, but with Engel as author/coauthor/whatever. It seems his name is like a golden seal to a shader programming book Both books cover obviously the same field (GPU programming), but don't relate to each other. I'm afraid, the "first" GPU Pro Book didn't received well recommendations on Amazon, anyone here owning that book?
