The value is a threshold, expressed as a ratio ranging from 0 to 1. The
lower the value, the higher the "level" of AA. With a value of 0, each and
every pixel in the scene is antialiased, whatever its contrast against its
neighbouring pixels. With a value of 1, only a perfectly black pixel
against a perfectly white one (or the opposite) would be antialiased.
If you have a strong pattern in your scene, such as wood, you might want to
soften moire artifacts by using jitter_amount greater than 1. Basically it
tells antialiasing to work not on one pixel at a time but to an area
slightly larger, thus "blurring" somewhat possible artefacts.
Just to be clear, please note that AA is not at all a post-process blurring
or softening process a la Photoshop. It actually makes Pov Ray compute more
information to avoid jagginess.
Hoping this helps!
