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.

Trajectory Rendering Modes

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

Show parent trajectories selected (1)

If you select a group object, trajectory will be rendered only for the highest one in the object hierarchy

Show all trajectories selected (2)

If you want to show trajectories for every selected point controller or object, choose this option

Show edges trajectories selected (3)

If this option is enabled, trajectories will show the positions of edges connecting selected point controllers.

Show objects and edges trajectories selected (4)

This mode shows positions on the selected point controllers and edges that connect them

Point controllers are shown as green points. In the current frame, they are marked with yellow circles

Only key frames (5)

If you enable this button, trajectories will consist only of the key frame positions of the selected point controllers

Trajectory fixing mode

This option is used for fixing trajectories. Unlike a regulat trajectory, a fixed trajectory remains visible in the Viewport even when you deselect corresponding objects, disappearing only when Trajectory fixing mode button is disabled.

This feature can work in several modes:

Show all trajectories fixed (1)

This button fixes trajectories for every selected controllers

Show edges trajectories fixed (2)

This button fixes positions of the edges connecting selected controllers (similar to the Show edges trajectories selected option)

Show edges and trajectories fixed (3)

This button fixes position of both controllers and edges that connect them

Only key frames (4)

If this option is enabled, trajectories will consist only of the key frame positions of the selected elements

Trajectory edit mode

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

Set trajectory interval

Press this button so trajectories won’t disappear when you select another interval
