Ah, kewl. From the looks of the screens, I still haven't gotten the lod values correct though @.@
Its kind of a hacky attempt tbh, but I was just surprised it didn't just break the world when I tried it. That I posted some screens here >.<
I'll take another look at improving it tomorrow anyway.
I also made a test just now with Xenosaga Episode I. There is no point in posting the screenshots. There is zero difference. Definitely a thing that helps some games and not others.
Blyss just sent me a PM telling me to go check this thread out. Your doing some really nice work Asmodean.
Alright Asmodean, it's broken for me! =(. I'll definitely keep an eye on this thread or wherever you decide to post updates on the AF attempts. When it does work, it's absolutely amazing blow my eyes off crazy good. Thanks for compiling it for me though, I'll just tinker around in the shadows.
Just to note: I did a quick test there. removing the AF, and reverting to linear, then changing the point filtering to linear also - and it didn't work. So it's definitely the anisotropic causing it, and not just the replacement of the point filtering to something else.
Oh that's good right! Proof that AF is actually a thing that works!
View direction/position will also have a big impact on its noticeability. Which is to be expected. See the screens below. Each with linear, and AF in the same spot, but at the different camera angle. First comparison is far more apparent than the second.
Linear1
Anisotropic1
Linear2
Anisotropic2
Still, it's a nice improvement, in general, seeing as it costs nothing.
Considering that was the angle of the camera in the Xenosaga test I did, I bet that's why there was no difference.
Still, I think it's definitely worth it. Some games I would prefer point, but some definitely AF. And a few I'd like to see HQ2X or something on(Ar tonelico for instance)
Well I think that's obvious isn't it? Anisotropic Filtering, the way I understand it, is to increase texture fidelity/visibility for angles that aren't isotropic/old school top-down or thereabouts angles. So 45 degrees would see a huge benefit where as 90 degrees wouldn't, as your picture shows very clearly.
Exactly.
Anisotropic filtering is most apparent at oblique angles.
