or body part, depending on what kind of fix

is needed.

Errors displayed as yellow lines in Curve View

If the results aren’t satisfactory, try changing

the parameters and fixing again. Repeat the

process until you find the combination of

parameters t hat correct the movement. Or try a

different fixer or filter (these are described later

in this topic).

Ani mati on Wor kbench Tools

The Animation Workbench provides three types

of tools to use with biped animation: analyzers,

fixers, and filters.

Analyzers

These are used to find out-of-the ordinary

properties in your animation. Certain analyzers

parse the waveform of y our motion tracks and

detect variation from the c u rves. There are two

detectors available that do this; Noise and Spike.

There are also analyzers for finding and fixing

knee conditions, specifically knee wobble and

extension.

For more information, see

Analyze Panel (page

2–869)

Fixers

Fixers address problems found by the analyzer.

The fixers work by running a specified operation

over just the analyzer result. They don’t change

the complete animation, just areas around the

problem.

For more information, see

Fix Panel (page 2–871)

Filters

Filters are operations that are performed on the

specified animation tracks. Unlike fixers, they

affect the complete specified time interval, not just

the ana lyzer result.

The Rot Smoothing, Rot Blurring, Rot Boosting ,

AdvRotSmoothing,PosSmoothing,PosBlurring

and Pos Boosting filters are all variants of one

type of filter. They all share the same par ameters:

Width and Damping.

For more information on these filter types, see

Filters Panel (page 2–874)

Navigating the Workbench

The Animation Workbench, a customized version

of Track View, uses some of the standard Track

View cont rols, and adds new ones of its own. The

areas of the Workbench interface incl ude:

• TheTabpanels:Select,Analyze,Fix,andFilter

• The Curve view, with Track View toolbars

for key selection, manipulation, and view

navigation.

• The Workbench toolbar, with tools for choosing

Coordinate space, display of sub-animations,

and tools to hide the Tab area and controller list.

Each sect ion of the Workbench User has specific

navigation techniques.
