Anti-Aliasing Controls and Settings |
Full Scene Anti-Aliasing (FSAA), Driver
Controlled |
Graphics driver Anti-Aliasing control is set
to override any application settings. The
entire Alias window is anti-aliased. There
is no distinction between a OpenGL viewport
and rest of the application. |
Benefit: Amount
of oversampling only limited by card
resources and graphics memory resulting in
extremely smooth shading. Anti-aliased
display is persistent |
Drawback: It
is not possible to toggle anti-aliased
display. Can cause noticeable degradation in
interactive performance. |
Full Scene Anti-Aliasing (FSAA), Application
Controlled |
This allows for Alias to use a 4x Full Scene
Anti-Aliasing from the graphics card. Only
modeling windows receive the Anti-Aliasing
visual and can be toggled ON and OFF. This
is enabled inside of Alias: Window
Display->Shaded Anti-Alias.... 'Allocate
Hardware Anti-Alias Resources on Startup'. |
Benefit: Only
modeling windows receive the Anti-Aliased
display resulting in less visual artifacting.
Can be toggled ON and OFF. Anti-aliased
display is persistent |
Drawback: Can
cause mild degradation in interactive
performance. |
Camera based Anti-Aliasing |
Anti-Aliasing is controlled entirely from
within the Window
Display->Shaded Anti-Alias....
Software Anti-Alias options and is only
applied when Hardware Shade or Diagnostic
Shade is enabled. The results are additive
to any existing FSAA if enabled in graphics
driver. |
Benefit: Not
dependent on graphics card and can easily be
controlled within Alias without restarting.
Various quality settings can easily be
specified for very high quality smoothing. |
Drawback: Anti-Aliasing
is only active during idle camera positions.
It is disabled during camera moves and
animation (playblasts do receive
Anti-Aliasing). Expect delays when used in
conjunction with other Hardware Shade
effects. |
