Selecting Biped Tracks 889
can be exp anded or collapsed in this way for the
arms, legs, ponytails, neck, tail, and spine.
In 3ds Max, you have the ability to display the
motion data as function curves. You can see and
manipulate funct ion curves either in the Track
View – Curve Editor, or by using the Workbench
(page 2–1012).TheWorkbenchprovides
specialized tools for analyzing and fixing motion
problems found in the curves.
For fast track select ion, you can also use the Track
Selection rollout. These buttons let you quickly
select the motion tracks for the horizontal and
vertic al movement of the biped center of mass, as
well as selection of opposite limbs, or symmetrical
limbs. Biped is unique in the way it separates the
tracks for the center of mass into three tracks (one
each for vertical, horizontal, and rotation).
