Title: Anisotropic Filtering
Post by: dgp9999 on 2002-01-19 17:06:00

We all know about the inner workings of Bilinear and Trilinear filtering, but this new technique, anisotropic, I don't know how this works, it's not pixel averaging, correct?

Could someone enlighten me?

I believe it's a type of filtering used to improve the visibility of textures when they're being shown at sharp angles. Not entirely sure how it works, though.

It's basically the next level after trilinear. And the more samples you use, the better it looks. Geforce1/2 supports 8 tap, Geforce3 supports 64tap, and the 3dfx Rampage(never released) supported 128tap.
