Parts to Filter Sets the filter to act on either the display object or the entire
selection of objects.
■ Display Curve Part Sets the filter to act on the displayed object curves.
■ Selected Parts Sets the filter to act on the active selection. Especially
useful when working on the whole biped.
Time to Filter Sets the range to be filtered to either the entire biped animation,
the active time segment, or a custom range of frames.
■ Entire Animation Sets the time to filter to be the complete biped
animation (disregarding the active time segment).
■ Active Time Segment Sets the time to filter to be the scene active time
segment. You set the active time segment in the 3ds Max Time
Configuration dialog.
■ From / To: Sets the time to filter to a custom range of frames.
Filters group
Filters list Choose the filter to use from this drop-down list.
The available filter types include smoothing, blurring, boosting, key reduction,
and subanims.
■ Rot filters work in quaternion rotation space, and modify the quaternions
of the specified animation tracks.
■ Pos filters work in the specified positional coordinate system, and modify
the positions of the animation tracks.
■ Blurring Uses basic Gaussian filters that take a weighted average over the
width. Blurring filters are good for smoothing out noise, but can also
over-smooth areas that aren't noisy.
See
Blurring, Smoothing, and Boosting parameters on page 4506, below.
■ Smoothing filters, on the other hand, are much better than blurring filters
for keeping the general shape of the track or curve. They affect only areas
that have big changes. The drawback of the smoothing filters is that they
don't change the curve as dramatically as the blurring filters do, so
sometimes you'll need to run the smoothing filter multiple times to smooth
out a particularly noisy area.
■ Adv Rot Smoothing works even better than the normal angular smoothing
filter when it comes to modifying only large changes and not small ones.

Blurring, Smoothing, and Boosting parameters on page 4506.
