Anti-aliasing

One of the most important settings for controlling the quality of your image—and the time it takes to render—is the Anti-aliasing parameter on the Quality tab of the renderer. This parameter is also shown in the Render Pixel Sampler. The square of the anti-aliasing number tells you the maximum number of primary rays that are traced per pixel of the image, or in other words the maximum samples per pixel. An anti-aliasing value of 3 means that up to 9 samples can be taken per pixel; a value of 8 means that some pixels may take up to 64 samples, and this is usually enough for very good images. An adaptive sampling technique is used to avoid taking the maximum number of samples where the sampler detects that the contrast between adjacent samples is below some threshold. This can be an effective way to concentrate anti-aliasing work where it is needed most, to increase quality and reduce the render time.

A parameter is an individual setting in a node parameter view which controls some aspect of the node.

A single element of an image which describes values for color and/or intensity, depending on the color system which the image uses. Groups of ordered pixels together form a raster image.
