whats that aniso filtering??

Mad · September 6th, 2002

does it improve image quality that much people talk about??
does my crad support it at good speeds??

Yes it does, but not as well as newer cards, and is likely very slow.
Anistropic filtering is a way to make textures which aren't straight on to the view plane look sharper.

I have no idea what your going on about

Take Quake 3 as an example, directlly in front of you the texures on the floor look really sharp yeah? look at the same floor textures further away and they look blurred yes?
Anistropic filtering is used to make those far away textures look as sharp as the close ones.

If you want to see the difference I guess the best thing that shows it is Jedi Knights 2. Ill post screen shots later on. Look at the ground when ur walking on 3d shooter games. You will notice that a little front of your character its all blurry and it clears the blur out when you get to that spot. Anistropic makes it look sharp and clean and detailed all the time. In easy words no blurs and little more lag.

nah, id rather speed!

It takes the average of a certain amount of pixels which is determined by the degree. Anisotropy is the distortion of texels and the filtering gets rid of that distortion. In conjunction with trilinear filtering it will push the mipmap border furhter and further untill you can't see it. I used to have some pics of the mipmap border with different aniso settings.

On the newer generation videocards you can enable anisotropic filtering with very little performance impact, and it can make games look a lot better. The Radeon 8500/9000/9700 in particular have very fast anisotrpic filtering methods, even at 64-tap.

I enable 64-tap anisotropy on my comp but get a -5~15fps hit
