Spring Controller (page 2–375):Addssecondary
dynamics effects to any point or object position.
Smooth Rotation Controller (page 2–374):Creates
smooth rotations.
Surface Constraint (page 2–396): Positions an
object along the surface of another object.
TCB Controller (page 2–377):ProvidesTension,
Continuity, and Bias controls for the function
cur ves b etween keys.
Transform Script Controller (page 2–379):Provides
scripted PRS control for objects.
Waveform Cont roller (page 2–381):Afloat
controller that provides regular, periodic
waveforms. For example, blinking lights and
rhythmic object motion.
XRef Controller (page 2–383):Letsyouexternally
reference any type of Transform controller from
another scene file.
Procedure
To a ssign a n animation controller in Track V iew:
1.
IntheTrackViewHierarchy,selectoneormore
parameter items of the same type.
2. From the Controller menu, choose Assign.
3. Choose a cont roller ty p e from t he Assign
Cont roller dialog.
If a parameter has already been animated,
then assigning a new controller has one of the
following effects:
• The existing animation values are
recalculated to produce a similar animation
with the new controller. For example,
replacing Position XYZ with Bezier Position
closely preserves the animation.
• The existing animation values are discarded.
For example, replacing Smooth Rotation
with Noise Rotation discards the Smooth
Rotation animation values.
Interfa ce
Assign Controller—Choose a controller type from
the Assign Cont rollers dialog. Depending on
thetypeoftrackyouhaveselected,theChoose
Controller dialog displays a subset of the different
types of controllers.
