Aliasing/Antialiasing
 
 
 

Aliasing is the staircase effect at the edge of a line or area of color when it's displayed by an array of discrete pixels.

Pyramid is aliased on left, antialiased on right.

Antialiasing smoothes the staircase effect that occurs when diagonal or curved lines or borders are drawn on raster displays consisting of square or rectangular pixels. Antialiasing can be either on or off. Turn this off only when you're rendering test images and want greater speed. Leave it on at all other times.

You can also turn antialiasing off for the Material Editor sample slots to speed up redraw of the sample objects. Click the Options button in the Material Editor and turn on the Antialias toggle on the Material Editor Options dialog. Default=off.

NoteTo control whether or not a background image is affected by the renderer's antialiasing filter, choose Customize Preferences Rendering and then turn on Filter Background in the Background group. Default=off.
