In animation, a tool for posing joint chains.
An IK handle resembles a wire running through a joint chain, and enables you to pose the entire joint chain in one action. As you pose and animate the joint chain, its IK handle automatically figures out how to rotate all the joints in the joint chain using an IK solver.
Types of IK handles include the IK rotate plane handle, IK single chain handle, IK two bone handle, and IK spline handle.
