select only a the portion of a curve to analyze.
Perform the analysis by clicking the Analyze
button. The errors are found based on the
detector’s parameter settings. If no errors are
found, try adjusting the parameters and clicking
Analyze again. Lowering the Standard Deviation
value will yield more errors.
When an error has been detected, the biped
part name appears in the Analyze Results list. If
multiple errors are detected, the entry displays a
number t hat tells how many errors were found.
Errors are also displayed in the Curve View as
vertical brown lines.
Once errors have been located, you can use the
tools on the Fix panel to correct those keys and

make changes using standard interpolation
techniques. R ight-clicking a key in the Curve view

such adjustments.
Results of the Analyze operation can
be loaded or saved as a file using the Load or Save
buttons at the bottom of the int erface.
Results of the last analysis can b e cleared
using the Clear button, a lso found at the bottom
of the panel.
Fi xin g Curv es
After you have selected curves and ana lyzed them
for error, you can use the tools found on the Fix
panel to process the curves and reduce the errors.
The fixes are determined by which type of fixer
you choose, and the parameters you set for that
fixer. Clicking Fix Selected or Fix All at the bottom
of the panel performs the Fix operation.
In general, fixes are made either by changing the
position or value of a key, or by removing the key.
The basic fixing techniques involve smoothing,
blurring, boosting, or key deletion. This is similar
to audio-editing software, where you view music

ways to alter the sound. Similarly, the motion

conditions regarding speed, angle, acceleration,

Of course, you can also fix curves manually. You
can select the key on the curve and move it, using
the standard Track View key buttons duplicated
in the Workbench, such as Move, Slide, Scale or
Delete Keys.

Workbench
The Animation Workbench is a tool for working
w ith biped function curves. It is a cus tomized
version of Track View, with many of the same
toolbars and buttons, pl us some new ones.
In addition to the standard Track View features,
the workbench has tools to help you select curves,
analyze them for er rors, and automatically fix those
errors based on various settings. This is especially
useful when working with mot ion-capture data, or
other animation that has many keys.
