thanks though this is more aniostropic than antialaising
i was playing around with this last night and havent been able to get good results though i believe im on the right path with the following
what i need though is a decent antialiasing method to calc A

frag = mix( A, B, distance( C,D ) )

have you thought about using the smoothstep function (assuming you're in GLSL)?
