• Knee Wobble —Fixes knees that wobble or shake
when a foot is planted. Uses a Knee Angle va lue
as criteria for error status.
•
K nee E x tensi on—Fixes knees that overextend
whenafootisplanted.UsesaFluctuationvalue
as criteria for error status.
Fixer parameters
Individual fixers display different par ameters.
These include:
•
Width—Determines how much of the curve is
affected around the keyf r ame.
All the Fixers except for Remove Keys display
this p a rameter.
•
Dampi ng—Determines how the fix is blended
into the existing curve. Changes how effective
the fixer should be. A higher value, the more
dramatic the change. A damping v alue of 1.0 is
normal behavior
All the Fixers except for Remove Keys display
this p a rameter.
•
Delete Keys—Allows for selective key removal
based on Interva l Width. When Delete Keys is
used, keys are removed only within the Inter va l
Width. When Delete Keys is not turned on,
Remove Keys wil l remove the selected keys
without considering the Interva l Width.
This parameter is available only when Remove
Keys is the fixer .
•
Inter val Width—Determines the number of
frames around the error to consider when
deleting keys.
This parameter is available only when Remove
Keys is the fixer .
•
K nee Angle— Sets the rotation angle to
determine what constitutes k nee extension
errors.
If the knee is planted and its angle is less than
or equal to the knee limit angle, then the
center-of-mass object is adjusted so that the
knee angle doesn’t exceed the limit.
This parameter is available only when Knee
Extension is the fixer.
•
Fr am e s — Determines the interva l to consider
for fluctuation evaluation.
This parameter is available only when Knee
Wobble is the fixer.
•
Flu ctua t i on — Establishes the amount of change
allowedbeforekneewobbleisidentified.
This parameter is available only when Knee
Wobble is the fixer.

the fluctuation threshold for 2 knee angles
w ithin the fr a me interval threshold, then the
knee’s angle is changed, so t hat the wobble is
eliminated.
Fix Sel ected—Applies the Fixer operation to the
selection in the Analyze Results error list.
Fix All—Applies the Fixer operation to all the
errors, whether they are selected in the Analyze
Results error list, or not.

Filters are simply operations that can b e performed
to different biped body parts. They are similar to
fixers, but they operate over an interval of time
rather than the results of the last analysis. Thus you
canuseafilterwithoutanalyzing. Certainfilters
share parameter types and functionality as fixers,
though the values are not shared and are distinct
for each filter. Use a filter whenever you want to
perform a general operation over a bo dy parts
motion, like smooth out or boost up some noise."
