In the Motion P anel, on the Quaternion/Euler
rollout, notice that the Quaternion option is
active by default.
Note: If you change options for that biped limb,
your choice is preserved in the
3dsmax.ini file,
from which it is restored after a scene reset or
session change.
6. On the Biped Apps rollout, click Workbench
to open it.
The animation is displayed as three separate TCB
rotation curves labeled “Quaternion Rotation”.
7. On the Quaternion/Euler rollout, choose the
Euler option.
Thecurveshavebeenconvertedtodisplay
Euler controlled rotations. You now have access
to the curve’s tangent handles to change the
cur ve’s interpolation.
The animation is displayed as three separate Euler
curves labeled “Tangent Euler Rotation”.
8. Choose a different axis ordering from the Axis
Order drop-down list (under the Euler option).
The cur ve display changes to reflect the new
ordering while preserving the biped posture.
9. Choose the Quaternion option to convert the
curves back to a TCB interpolation.
Note: Convert ing a curve from Euler to
quaternion can affect its interpolation.
See
Working w ith Euler Curves on Biped
Animation (page 2–861)
for details.
Interfa ce
Thefollowingoptionssettherotationcontroller
for biped animations.
Quaterni on — Converts the selected biped
animation to quaternion rotation. If the biped
selection has not bee n animated yet, this starts as
the default option.
If you change options for any biped limb, your
choice is preserved in the
3dsmax.ini file, from
which it is restored after a scene reset or session
change.
Euler — Converts the selected biped animation
to Euler rotation.
Axi s Orde r — L ets you cho ose the order in w hich
the Euler rotation curves are calculated. Availabe
only when Euler is active. Default=YXZ.
Changing the ordering reflects on the curves,
which are modified accordingly. However, this
change does not affect the animation itself.
Note: This setting is independent of the Workbench
Axis Order setting.
