Please have a look into this,
Scroll down to the 360 DEGREES OF CARISMA . you will see a car model. While rotating that car, you can see so many aliasing on the edges. But, when you leave the interaction, all aliasing will be antialiased. At that time, if you see sharply on those aliasing, something will running on those aliasing edges in the opposite direction to antialias those aliasing effect. What is the process takes place on that? any ideas?
