13. Intro to Inverse Kinematics

Inverse kinematics (IK) is a method of animating objects and shapes that relies on a skeleton-like structure (an armature) with multiple linked segments (bones). Once you set up the structure, you can manipulate it to create various configurations, or poses.

Imagine manipulating a human skeleton; if you raise the hand and bring it in toward the torso, the forearm also raises, and the elbow bends. Similarly, if you move one bone in an IK armature, connected bones move in response.

Flash interpolates changes between poses to create animation. You can use IK armatures to link multiple symbol instances, thereby controlling their ...
