Anti aliasing effect

Please have a look into the below links,

In these two , while rotating the object, the aliasing effect is there. But once we release the control. Then Automatically the aliasing is merged and antialiased cleanly. How can we achieve this. any suggestions please.

You can remove the anti-alisaing while the camera is moving and set it back when it is resting:


Thanks a lot @Evgeni_Popov
