NVIDIA DDS PhotoShop plugin: new filters

[GPSnoopy]

It's a nice tool from NVIDIA, but what the hell are (in mipmap generation part):
- Kaiser Filter
- Linear Light Kaiser
- Full DFT

???

I know what are Cubic and Box filters. But what about the others? What do they do? Which one is better? etc...
Only thing I found out is that DFT stands for Discrete Fourier Transform http://www.opengl.org/discussion_boards/ubb/wink.gif

There was a couple articles in GDMag, i think in decembers and januarys. The article talks about using different filters than the typical box to generate the mipmaps. You might be able to find the article on Gamasutra.
