rotates independently of the neck, and interpolation of these individually set
orientations produces more natural-looking motion.
Similar to the head and arms, changing the orientation of the upper or lower
leg changes the position, but not the orientation, of the corresponding foot.
In this way, the foot orientation remains relative to the ground plane.
Adjusting Keys with TCB Rotation
Rather than creating extra keys to fine-tune the motion of the biped limbs,
you can use the TCB controls to adjust ease in, ease out, and limb trajectory
on keys that already exist.
Visualizing Rotation Animations with Function Curves
Another way to visualize your rotation animation is through the
Curve Editor
on page 3518. Each key you add is displayed and connected to other keys,
creating a curve that represents your animation. You can use either the
TCB
Rotation Controller
on page 3258 or the Euler XYZ Controller on page 3151 (on
the
Quaternion/Euler rollout on page 4355) to display your rotation curve as
Quaternion or Euler, respectively. Each controller affects the curve differently
based on separate rotation calculations. To learn more about this, refer to
Working with Euler Curves on Biped Animation on page 4293.
