Anti-Aliasing - Concepts

Anti-aliasing improves your rendered scenes by removing the jagged effect observed along straight edges and in text. Jagged edges occur because of the inherently square shape of each pixel in your display. Lower-resolution images have a higher chance of displaying jagged edges because of their lower pixel count. In Render mode, Anti-aliasing is achieved by redrawing the rendered scene a specified number of times, each time jittering the image by a small amount, so that in the hard edges are softened by displaying slightly lighter pixels adjacent to the dark ones. The eye is fooled into seeing straighter lines and smoother curves (instead of jagged edges). AGi32 does this automatically when Anti-aliasing is enabled as you navigate. The image is anti-aliased the moment navigation stops .

 

The amount that the image is jittered is determined by the Anti-Aliasing Sampling Level specified on the Status Bar. The levels available are: None,  2, 4, 8 and 15. Increasing the Sampling Level will increase the time it takes AGi32 to apply the Anti-aliasing so you may notice a slight pause when you stop navigation to complete the process. Determining which level is appropriate will depend on your screen resolution and severity of jagged edges in the image. Lower screen resolutions and severe jagged edges will demand the highest sampling levels.

If Anti-aliasing is active (Sample Level > None), Anti-aliasing is applied to all Render views when Render mode is closed (for use in Imageports with Reports).

NOTE: Some graphics cards disable manual Anti-aliasing when Hardware Acceleration is equal to Full. If you are not seeing Anti-aliasing  applied, turn down the Hardware Acceleration on your Windows™-Display-Properties-Troubleshooting tab.
