Trajectories

 

trajectory is a line that shows the path travelled by a selected object across a selected interval

 

To make a trajectory visible, select an object in the Viewport and an interval on the Timeline.

 

Tools for switching Trajectory rendering modes can be found on the UI panel at the top

The first button enables rendering trajectories for selected object. By default, if you select a group object, trajectory will be rendered only for the highest one in the object hierarchy. So if you want to show trajectories for every selected node, choose the second mode. The third mode renders trajectories and edge positions.

If you enable the Only key frames button, trajectories will consist only of the key frame positions of the selected nodes

  • Press the Show edges and trajectories selected button so trajectories won’t disappear when you select other objects
  • Press the Set trajectory interval button so trajectories won’t disappear when you select another interval
  • Cascadeur also gives you an option to edit trajectories. First, you need to enable this feature by pressing the Trajectory edit mode button. After this, you can move, rotate and otherwise adjust the point of a trajectory by applying standard manipulators.

 

Note: If you edit a trajectory for one or more frames in an interpolation interval, the interpolation mode for this interval will be switched to Fixed
