In the Thresholds and Solutions group you can refine the IK solution. The
Position Threshold sets a limit in units of how far the goal can be moved from
the end effector, the Rotation does the same in angle degrees.
The Solutions group Iterations is the maximum number of attempts the IK
solution will perform before giving up.
If your IK animation seems to jitter, try increasing the Iterations to 200.
Increasing the Iterations will slow down the computational time, but should
produce better results.
Manipulator for the Swivel Angle
You can adjust the swivel angle with the spinner in this rollout, or you
can adjust it with a manipulator. To do so, turn on
Select and Manipulate on
page 2613. The swivel angle manipulator is displayed as a handle in the
viewports.
