In the next steps, you create a joint chain for the spinal column. You also
extend a joint from the upper neck region of the joint chain so that you can
animate the jaw.
To create joints for the spine and jaw
1 In the side view, use the Joint Tool to create a series of joints at the
locations shown in the figure. Start at the base of the spine near the
existing hip joints (left_hip and right_hip) and end at the top of the head.
Make sure you create the first joint a little bit away from the existing hip
joint displayed in the front view. Otherwise the first joint will be
connected to the hip joint. Remember to press Enter (Windows and
Linux) or Return (Mac OS X) when you are done creating the joint chain.
With the exception of the joints at each end of the joint chain, the joints
are located where the character is likely to bend or twist at the spine and
neck.
