Because the image on a monitor is made up of discrete pixels on a fixed grid,
scenes rendered using the Draft or Low render presets produce jagged and
inaccurate images.
In the following example, image quality is highly degraded - Min. Samples =
1/64; Max. Samples = 1/4.
The greater the resolution (and thus the smaller the pixels), the less apparent
aliasing is. However, it is often best to reduce the effect further by using
anti-aliasing techniques. The anti-aliasing technique used by the renderer is
called sampling. Sampling is controlled by the sample and filter settings on
the Advanced Render Settings palette.
Sampling provides a "best guess" color for each rendered pixel. The renderer
first samples the scene color at locations within the pixel or along the pixel's
edge, then uses a filter to combine the samples into a single pixel color.
Increasing the minimum and maximum sample ranges greatly improves the
quality of a rendering.
In the following example, increased sampling smooths edges - Min. Samples
= 1; Max. Samples = 16.
