Inverse Kinematics

Is the process of determining the movement of interconnected segments of a body or model. Using ordinary Kinematics on a hierarchically structured object you can for example move the shoulder of a puppet. The upper and lower arm and hand will automatically follow that movement. IK will allow you to move the hand and let the lower and upper arm go along with the movement. Without IK the hand would come off the model and would move independently in space. Blender Armature Sistem include Inverse Kinematics.
