■ Constant velocity control.
You can adjust the key interpolation by choosing among different tangent
types in the Key Info dialog. .
TCB Controllers
The
TCB controller on page 3258 produces curve-based animation like Bezier
controllers. However, TCB controllers use fields to adjust the Tension,
Continuity, and Bias of the animation.
Use TCB controllers when you want adjustable, curved interpolation between
keys, and you want to use TCB style controls.
Linear Controllers
The
Linear on page 3193 controller interpolates between animation keys by
evenly dividing the change from one key value to the next by the amount of
time between the keys.
For a rigid, mechanical motion, use Linear controllers.
Noise Controllers
The
Noise on page 3214 controller produces random, fractal-based animation
over a range of frames. Noise controllers are parametric; they do not use keys.
Noise controllers have many possible uses, as in the following examples:
■ Use Noise whenever you need completely random animation around a
given value. For example, use a Noise Rotation controller when you want
an object to wobble in place. A common use for a noise controller is the
creation of camera shake.
■ Use Noise in a List controller to apply variations to the result of another
controller. For example, use a List controller to combine Noise Position
with Bezier Position. The Bezier controller moves the object while the
Noise controller makes the object shake and stray a little from the
trajectory.
XYZ Controllers
The XYZ controllers such as
Euler XYZ on page 3151 and Position XYZ on page
3219 are specifically designed so that you have three separate curves, one for
each axis. This allows you to independently view and control the curves
