Does anyone find this statement a Joke ??

The digit-life article doesn't actually explain why a plane at 45 degrees has no aniso. To me, the article seems to imply that the 8500s aniso depends on UV orientation, which it doesn't. Unless I'm reading it wrong.

Exactly. As i said above, the digit-life article is wrong, from what i understand of it.
It seems to be supporting rip-mapping as the idea, when its not.
Just spin in a circle on any map and you know its not rip-mapping.

I think it was Pcchen's little app. It was even put in a magazine article that it was rip mapping showing a screen shot of Pcchens little program..

Does anybody still have a copy of this app?

Hmm, I don't get it, why the Digit Life theory fails in your opinion? To me, what DL explains doesn't look like rip mapping. Their theory would also be a reason for the high performance. With texture sampling only in one row and not diagonal in texture space, I guess you could implement a very efficient texture caching algorithms.

Doomtrooper,

were the hell do you find all of those funny animated gifs? I laughed so loud I think I woke up the cublical police.

Ram,

I have a mirror of it here:

I deleted it last night in a general tidy up

Because the issue isnt in "texture space" - if thsi was the case, texture filtering would change as you rotated around a texture, and this simply isnt the case. Its only when the "roll angle" of the polygon that the texture is on changes that your filtering quality changes. Thier article seems to imply that the problem is how the textures are sampled (it being dependent ont he angle to the texture) but this isnt the case.
