Animation Workbench 1013
Of course, you can also display and manipulate
function curves for bipeds in the standard
3ds Max Track View and expanded track bar, as
well. However, you have access to the automatic
error-analysis tools only in the Workbench
Note: OnthetimesliderorinTrackView,you
can move one Biped key past another. See Moving
Keys (page 2–1004).
The Animation Workbench displays rotation
cur ves in local biped space for both quaternion
and euler rotations. This improves the speed of
curve manipula tion since the whole biped doesn’t
need to b e calculated in order to draw a single
cur ve.
Note: T his does not affect position curves, which
are still evaluated in world space.
Note: Curve display will only change for certain
objects in COM space: base of spine, neck,
clavicles, upper arms, upper thighs, and feet.
Pr ocedur es
To display the local rotation curve of an animated
spine link :
1.
Create a biped and select its upper spine lin k.
2. Setakeyatframe0.
3. Go to frame 10 and rotate the spine link
30 degrees in the local Z axis.
4. Open the animation workbench.
Only one curve is displayed because the upper
spine rotates in local space by defa ult.
5. Select the biped’s head.
Notice how there are no curves in the
workbench because the head doesn’t inherit
the spine lin k’s rotation and doesn’t have an
internal rotation of its own.
