Toggles anti-aliasing of shaded surfaces.
Use this tool to turn anti-aliasing on and off on shaded surfaces. This applies to surfaces shaded using either WindowDisplay > Hardware Shade or Diagnostic Shading. You have the choice of two methods to anti-alias shaded surfaces: Software Anti-Alias and Hardware Anti-Alias.
Software anti-aliasing gives you a better quality result, but does not apply while you tumble in the view. Once you stop tumbling, there might be a time lag while the anti-aliasing is re-applied. Hardware anti-aliasing works during tumbling as well but the quality is less. You can use both methods simultaneously if you want.
To use the Hardware Anti-Aliasing method, you must first check on Allocate Hardware Anti-Alias Resources on Startup, then set Hardware Anti-Alias to On. You need to restart your computer for those settings to apply.
Once you have chosen the appropriate settings in the option boxes, you only need to select the menu items to turn the anti-aliasing on (check mark) or off (no check mark).
