I wrote a little mini-tutorial on antialiasing over at GamingW:
http://www.gamingw.net/forums/index.php?&act=ST&f=11&t=21155
If you guys like this, I might start writing more tutorials of this type and group them all into a webpage somwhere. Let me know if you find it confusing or want some more info on the ideas behind it - I've never really written tutorials before. :)

The idea behind it isn't _that_ complicated... if you want a black pixel on the screen on a white background but right in the middle of 4 pixels, just make those 4 pixels not as strong as you normally would... then you can apply this to images.

What I want to see is an explanation of 'interpolation'. I was reading about persepective correct texture mapping and all the tute talked about was interpolating the u,v coordinates along the scanline or something.

Mattrunks, you need to be on more often. Glad to see you on though.

That's actually this theory in reverse. All you need is floating point pixel coordinates and you can apply the basic algorithm my (complicated) tutorial explains. :)

Yeah, I've sorta taken a break. But I think I'm gonna work on my art and music skills (and programming too) and try and find someone to work with.
