Use Assign Controller to assign animation controllers to any animatable
parameter or track in Track View.
Animation controllers provide powerful tools for animating all the objects
and materials in a scene. For example, rather than keyframing the position
of an object in your scene, the object can follow a spline using the Path
constraint, react to any animated parameter using a Reaction controller, or
move to the beat of music using the Audio controller. You can combine
controllers with a List Controller. You can drive a single vertex or control
point on a complex object by a variety of controllers.
You can also assign controllers using the right-click menu in the Track View
Controller window. Or you can assign controllers in the Motion panel, in
Schematic View, and by using the Animation menu.
Constraints and Controllers
Technically, there is no difference between a controller and a constraint. A
constraint is simply a controller that requires the use of a second object. For
example, a Path constraint is a controller that requires a spline object for a
path.
Special-Case Controllers
Special-case controllers are not assigned manually with the Assign Controller
command. They are applied automatically during certain procedures.
Barycentric Morph Controller is applied by selecting an object and clicking
Command panel > Geometry > Compound Objects > Morph.
A Master Point Controller is assigned when animating vertices, control points,
or vectors in the sub-object mode of an Editable Mesh, Editable Spline, Editable
Patch, NURBS surface, or FFD modifier.
