描述
|
|
----
|
|
|
|
**FABRIK3D** is position based IK, allowing precise and accurate tracking of targets. It's ideal for simple chains without limitations.
|
|
|
|
The resulting twist around the forward vector will always be kept from the previous pose.
|
|
|
|
\ **Note:** When the target is close to the root, it tends to produce zig-zag patterns, resulting in unnatural visual movement.
