Trajectories

 

trajectory is a line that shows the path traveled 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

1. Show parent trajectories selected

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

2. Show all trajectories selected

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

3. Show edges trajectories selected

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

4. Show objects and edges trajectories selected

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

5. Only key frames

In this mode, you will see trajectories of the selected point controllers in the keyframes.

Trajectory fixing mode

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

This feature can work in several modes:

1. Fix all trajectories

This button fixes trajectories for every selected controllers

2. Fix trajectories edges

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

3. Fix edges and trajectories

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

Trajectory edit mode

To edit a trajectory you need to enable the Trajectory edit mode button. After this, you can move, rotate and otherwise adjust any 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
