Twist Poses Rollout 805
Twist Poses R ol lout
Select a biped. > Motion panel > Twist Poses rollout
The toolset of this rollout lets you create and edit
tw ist poses for a biped’s limbs. You can either use
the rollout ’s preset poses (which you can modify
and rename), or create your own. When you add
a new pose, you establish a reference between
theselected’slimbrelativeorientationandthe
rollout’s Twist value of 0 (which means no tw ist).
When more than one reference pose are set for a
rotatedlimb,thelimb’stwistingiscalculatedbased
on the n earest pose.
Tip: It is suggested that you add twist poses
forallmajorlimbrotatedposes. Thisensures
that rotating your biped’s limb produces
well-calibrated twisting.
Note: You don’t technically have to enable twist
links (page 2–839)
to use the Twist Poses rollout
toolset. However, if yo ur biped does not contain
twist lin ks, the Twist and Bias s ettings are not used.
The Twist Poses rollout tools only affect limbs w ith
three degrees of freedom (D OF), such as upper
arms and thighs, because you can control their
tw ist links by rotating them. Two-DOF limbs
(forearms and calves, for instance) differ due to
the fact that you can only control their twist links
if you rotate their child limb.
The upper arm can t w ist itself while the fore arm need s the
wrist to twist it.
Note: If you select a two-DOF limb, the only
available setting is the Bias value; you can change it
to adjust the rotation distribution along the twist
links.
Procedures
Exa mple: To Add a nd Edit Twist Poses:
This procedure takes into account the concept of
adding
twist links (page 2–839) to biped limbs
and concentrates on using the tools from the Twist
Poses rollout to set up basic poses.
1. Prepare a biped with five twist links on each
upper arm.
Tip: Yo u c a n u s e See-Through (page 1–55) on
the biped’s limbs to better distinguish the twist
links inside.
