42 Anti-aliasing

Anti-aliasing
Anti-aliasing is a technique used to smooth out the jagged edges of three-
dimensional curved objects or objects with diagonal edges.
Anti-aliasing can be set to favor either an increase in system processing
performance or improved image quality:
• Setting for performance is best used when the 3D image is
animated and smoothness of motion is the most important
consideration.
• Setting for quality is best used when having highly detailed and
realistic 3D objects is the primary concern.
• If you are unsure of how to configure anti-aliasing, use the Let the
Application Decide option. Your display will automatically adjust
to the application's requirements.
