Controllers, like constraints, handle the animation tasks in a scene, including:
Storing animation key values
Storing procedural animation settings
Interpolating between animation key values
Objects and parameters don't receive a controller until you animate them. As soon as you change a parameter with Animate on, or click in its track using the Track View Add Keys, the software assigns a controller to the parameter. The software chooses a default type for the controller, depending on the animation. You can change the default controller to some other type.
The animation controllers are organized in the following categories:
Float controllers: for animating floating-point values
Point3 controllers: for animating three-component values such as colors or 3D points
Position controllers: for animating positions of objects and selection sets
Rotation controllers: for animating rotation of objects and selection sets
Scale controllers: for animating the scale of objects and selection sets
Transform controllers: for animating general transforms (position, rotation, and scale) of objects and selection sets
To change an assigned controller, use Assign Controller in Track View or in the Motion panel.
The controllers and constraints are:
PRS Transform Controller (Position, Rotation, and Scale)
TCB Controller (Tension, Continuity, and Bias)
