page 4489 to select biped parts by name. The functionality of the Select panel
is derived from the
Selection Floater on page 231; you can invert the selection
set or enter a name into the Selection field to find a track.
You can also use the controller window as a selection
mechanism. With the Controllers list visible you can click on track entries
there to work on the curves.
NOTE Sometimes a curve will not appear in the display at first. Click Zoom Extents
Horizontal and Zoom Extents Vertical to make sure the curve can be seen.
The Workbench toolbar lets you choose the type of curve to display and the
coordinate space in which it is displayed. For example, if you know you are
dealing with rotational errors, choose an Rot or Quat type curve. If it is an error
of positional data, choose Pos.
If you open the Track View – Curve Editor or expand the track bar while you
have the Workbench open, you will see a simultaneous display. The views are
all synchronized, so selecting a track in one graph editor selects it in all.
When using footstep animation, you can see the footstep keys by opening a
Track View – Dope Sheet window.
Analyzing Curves
Once you have selected curves, you can analyze them to discover error
conditions. You choose between four kinds of detectors; Noise, Spike, Knee
Wobble or Knee Extension. You can also 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 that
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 the keys around them. Or you can use the error location merely
to identify the keys, then manually make changes using standard interpolation
techniques. Right-clicking a key in the Curve view will display the properties
dialog that allows for such adjustments.
