3 Bina Nusantara Inverse Kinematik (IK) & Forward Kinematik (FK) 3 Animation part 1

4 Bina Nusantara Hierarchies and Kinematics …….” The term kinematics describes the movement or animation of the chain. There are two types of kinematics:kinematics With forward kinematics (FK), you transform a parent object to move its descendants (its children, their children, etc.).forward kinematics With inverse kinematics (IK), you transform a child object to move its ancestors (its parent and so on up the chain). You can also use IK to make an object “stick” to the ground or another surface, while allowing the chain to rotate off the pivot of that object.inverse kinematics 4

5 Bina Nusantara The default method of manipulating a hierarchy uses a technique called “forward kinematics”. The basic principles employed by this technique are: Hierarchical linking from parent to child Placement of pivot points to define the connecting joint between linked objects Inheritance of position, rotation, and scale transforms from parent to child Forward KinematicsForward Kinematics (FK) 5

7 Bina Nusantara 7 Inverse KinematicsInverse Kinematics (IK) ……” Inverse kinematics (IK) is a positioning and animation method that is built on top of the concepts of hierarchical linking. To understand how IK works you must first understand the principles of hierarchical linking and forward kinematics. Inverse kinematics starts with linking and pivot placement as its foundation and then adds the following principles: Joints are constrained with specific positional and rotational properties. Position and orientation of parent objects is determined by the position and orientation of child objects.
