Quaternion/Euler Rollout 949
From left to right, the biped at frame 0, 20, and 40.
In the Motion Panel, 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 3d smax.ini (page
1–18) 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 ha v e 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 curve 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: Converting a cur ve f rom Euler to
quaternion can affect its interpolation. See
Working with Euler Curves on Biped Anim ation
(page 2–916) for details.

Quatern ion Converts the selected biped
animation to quaternion rotation. If the biped
selection has n ot been anim ated yet, this starts as
the default option.
If you change options for any biped li mb, your
choice is preserved in the 3dsmax.ini file, from
