i have this 3d game im working on and the walls of this room are bricks. everything is fine, however when the player moves far away the picture of the bricks are messed up. i have uploaded a screen shot to photo bucket. i have also tried different filters for when your close/far but still the same thing.
I found this: http://www.cpp-home.com/tutorials/36_1.htm
You could Google moire pattern textures 3d if you want to find more info.
Mip mapping is also used to speed up interpolations, by the way.
