Converting the Camera Analyzer Results

When you are satisfied with the results of the 3D camera tracking analysis, you can convert the selected reconstructed points to a point cloud object or actual axes in your scene. The point cloud object is useful because you can easily snap objects to it.

To create a point cloud object or axes from the 3D camera tracking results:

1. Select the points in the image that you want converted to a point cloud 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. Enable Fixed Camera if you want to generate a fixed camera and a moving 3D point cloud.

   Typically, 3D tracking results in a moving camera and fixed points, but you also can set the camera to be fixed and the points to move.

3. Do one of the following:
   - Click Create Point Cloud

     Selected point are converted to a point cloud object with a parent axis. Double-click the newly created point cloud object to access its menu, where you can change display settings and enable snapping. See Using the Point Cloud Object.

   - Click Create Axis

     Selected points are converted to axes with a parent axis. The axes synchronize to the results of your 3D camera 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.
4. Use the created point cloud or axes to view the reconstructed scene geometry or camera motion.

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