AF

So what is anisotropic filtering anyway?
I just notice that when I turn it on, image quality looks nicer. Explanations please?
Thanks!

Darn, I thought you were talking about "autofocus" - something I might actually have been able to comment on. 😉

I'm curious about this topic, too. 🙂

I dunno what it actually is. But it makes 2D textures placed on 3D sufaces clearer. It is more pronounced at the textures get farther away.

It makes textures in the distance sharper. The cool thing is that it has very little performance impact.

Anisotrophic filtering samples textures at different angles, so they look sharp from all angles. Try turning AF off, fire up any FPS game, stand next to a wall, and walk along side of it, looking at the wall textures. Without AF, the textures farther along the wall will get blurry. AF fixes the problem.

Anisoptropic filtering uses a non-square sampling pattern taken in the direction of the view's stretch to reduce texture distortion.

In simple terms it makes things sharper.

Yea thats what I noticed when AF was off.
I just never understood the concept behind it.
At least now I have some clue as to what is going on.
Thanks
