The export of individual nodes can be enabled/disabled in the Export Options tab.
Update Previous Export
When this button is clicked, the previously exported nodes are updated with any new data
generated. These previously exported nodes are remembered in the Previous Export section at
the bottom of this section. Here’s an example of how this is handy:
1 Solve the camera and export.
2 Construct a complex Node Editor based around the exported nodes for use in set
extension.
3 The camera is not as accurate as preferred or perhaps the solver is rerun to add
additional tracks to generate a denser point cloud. Rather than re-exporting the
Camera 3D and Point Cloud 3D nodes and connecting them back in, just press the
Update Previous Export button to “overwrite” the existing nodes in place.
Automatically Update Previous Export After Solves
This will cause the already exported nodes (Camera 3D, Point Cloud 3D, Lens Distort, Renderer
3D, and the ground plane) to auto update on each solve.
3D Scene Transform
Although the camera is solved, it has no idea where the ground plane or center of the scene is
located. By default, the solver will always place the camera in Fusion’s 3D virtual environment
so that on the first frame it is located at the origin (0, 0, 0) and is looking down the -Z axis. You
have the choice to export this raw scene without giving the Camera Tracker any more
information, or you can set the ground plane and origin to simplify your job when you begin
working in the 3D scene. The 3D Scene Transform controls provide a mechanism to correctly
orient the physical ground plane in the footage with the virtual ground plane in the 3D viewer.
Adjusting the 3D Scene Transform does not modify the camera solve but simply repositions the
3D scene to best represent the position of the live-action camera.
NOTE: If you export the scene and then make changes in the 3D Scene Transform, it is
important to manually click Update Previous Export to see the results in the
exported nodes.
Aligned/Unaligned
The Aligned/Unaligned menu locks or unlocks the origin and ground plane settings. When set
to Unaligned, you can select the ground plane and origin either manually or by selecting
locators in the viewer. When in unaligned mode, a 3D Transform control in the 3D viewer can be
manually manipulated to adjust the origin.
Once alignment of the ground plane and origin has been completed, the section is locked by
switching the menu to Aligned.
Set from Selection
When set to unaligned, buttons labeled Set from Selection are displayed under the Origin,
Orientation, and Scale sections. Clicking these buttons takes the selecting locators in the
viewer and aligns the ground plane or origin based on the selection.
