The Multiresolution Adaptive Antialiaser dialog
changes settings for the Raytrace material and
maps Multiresolution A daptive antialiaser. You
can use this dialog either globally, from the
Global
Raytr acer Settings dialog (page 2–1369)
,or
locally, from the
Raytracer Controls rollout (page
2–1362)
. When you locally change sett i ngs for an
antialiaser, you don’t affect the global s ett ings for
that antialiaser.
Interfa ce
Adaptive Control group
Initial R ays—Sets the initial number of rays cast per
pixel. Default=4.
Threshold—Determ ines the sensitiv ity of the
adaptation algorithm. It can range from 0 to 1,
where 0 always casts the maximum number of rays
and 1 always casts only the minimum number of
rays. Default=0.1.
Max. Rays (Maximum Rays)—Sets the maximum
number of rays the algorithm will cast. Default=32.
Blur / Defocus (Distance Blur) group
Blur Offset is similar to
blur offset (page 3–1012)
for bitmaps, while Defocusing is based on distance.
Blur Offset—Affectsthesharpnessorblurriness
of the reflections or refractions without regard
to distance. You can use Blur Offset to soften or
defocus the details of a reflection or r efraction.
The value is specified in pixels. Default=0.0.
Tip: The default Blur Offset setting usua lly
produces good results. If you see aliasing in
reflections or refractions, increase its value in
increments of 0.5 until the aliasi ng go es away.
