Inverse Kinematics
Ensure that only one object is selected before using the Inverse Kinematics
tool. If multiple objects are selected, the IK tool will be unable to move
them.
This tool enables you to move hierarchical objects interactively using inverse kinematics (IK). For
example, you can grab the hand of an arm and move it to the required position. The arm will follow
automatically, obeying any rotation restrictions you have applied to the joints.
The optional MOCCA module features advanced tools to achieve outstanding
control over character animation, including a new IK system (Soft IK) with
built-in dynamics and constraints that allow more uid motion. For full
details on MOCCA, please contact your local MAXON representative or visit
www.maxon.net.
Not only is the IK tool useful for animation, it’s also ideal for posing characters. You will need to
arrange the objects into a hierarchy and assign Kinematic tags. If you select an object at the end of a
hierarchy and move the mouse, CINEMA 4D calculates the distance between the joints automatically
and keeps it constant. This prevents the chain (e.g. an arm with several joints) from pulling apart.
