The Trajectories rollout displays the path an object travels over time. Controls
to convert splines into trajectories, trajectories into splines, and to collapse
any transform controller into editable keys are also available by choosing
Motion panel > Trajectories.
NOTE The state of the Trajectory check box under Display in the Object Properties
dialog
on page 305 (and on the Display panel > Display Properties rollout) controls
whether trajectories will be visible for an object.
Using trajectories, you can do the following:
■ Display the 3D path for selected object’s position tracks.
■ Insert and delete keys from the path.
■ Move, rotate, and scale keys on the path.
■ Convert the path to a spline object.
■ Derive a new path from a spline object.
■ Collapse transforms.
Values under Sample Range are used in the Spline Conversion and Collapse
Transform functions.
NOTE You can assign the four principal Trajectories functions to keyboard shortcuts
and other custom UI items. The following actions are available via
Customize User
Interface
on page 7697:
■ Trajectory Add Key Mode Toggle : Enters and exits Add Key mode on
page 3124.
■ Trajectory Delete Key : Activates the
Delete Key on page 3124 function on
a one-time basis.
■ Trajectory Key Mode Toggle : Enters and exits the Keys sub-object level
for direct editing of animation keys via transformation of the trajectory
keys.
■ Trajectory Toggle : If one or more objects are selected, this enters and
exits Trajectories mode on the Motion panel.
