Converting the 3D Auto Tracking Results
 
 
 

When you are satisfied with the results of the 3D auto camera or object tracking analysis, you can convert the selected reconstructed points to actual axes in your scene.

To create axes from the 3D tracking results:

  1. Select the points in the image that you want converted to axes. Selected points are displayed as green squares with red crosses.
    TipPress ctrl and draw a rectangle over multiple points to select them. If any points are already selected, they become unselected.
  2. Click Create Axis.

    If you performed Camera Tracking, selected points are converted to axes with a parent axis called Points_3dt_sync. If you performed Object Tracking, the parent axis name corresponds to the name in the Object Properties Name field. The axes synchronize to the results of your auto 3D tracking, and any further changes you make to the 3D track are reflected in these axes.

    NoteIf you want to apply settings manually to a synchronized axis, change its name so that it does not update automatically when 3D Track settings are changed. If you reset the 3D Track settings, the synchronized axes become regular Action axes.
  3. Exit the 3D Track menu. Use the created axes to view the reconstructed camera motion.

    You can attach objects such as surfaces, 3D text, and 3D models to the new axes to help position them in 3D space.

You can export the newly created camera, as well as the axes and points created from the 3D tracker analysis, to .fbx format for use in other 3D applications. See FBX Cameras.
