For instance, to set the ground plane, do the following:
1 After solving, set the 3D Scene Transform menu to Unaligned.
2 Find a frame where the ground plane is at its largest and clearest point.
3 In the viewer, drag a selection rectangle around all the ground plane locators.
4 Hold Shift and drag again to add to the selection.
5 In the Orientation section, make sure the Selection Is menu correctly matches the
orientation of the selected locators.
6 Click the Set from Selection button located under the Orientation parameters.
7 Set the 3D Scene Transform menu back to Aligned.
To get the best result when setting the ground plane, try to select as many points as possible
belonging to the ground and having a wide separation.
TIP: When selecting points for the ground plane, it is helpful to have the Camera
Tracker node viewed in side-by-side 2D and 3D views. It may be easier to select tracks
belonging to the ground by selecting tracks from multiple frames in the 2D viewer
rather than trying to box select locators in the 3D viewer.
Setting the origin can help you place 3D objects in the scene with more precision. To set the
origin, you can follow similar steps, but only one locator is required for the origin to be set.
When selecting a locator for the origin, select one that has a very low solve error.
Ground Plane Options
These controls let you adjust the ground plane for the scene, which is a crucial step in making
sure the composite looks correct.
Color Will set the color of the ground plane.
Size Controls how big the ground plane can be set.
Subdivision Level Shows how many polygons are in the ground plane.
Wireframe Sets whether the ground plane is set as wireframe or solid surface when
displayed in 3D.
Line Thickness Adjusts how wide the lines will draw in the view.
Offset By default, the center of the ground plane is placed at the origin (0, 0, 0).
This can be used to shift the ground plane up and down along the y-axis.
Export Options
Provides a checkbox list of what will be exported as nodes when the Export button is pressed.
These options are Camera, Point Cloud, Ground Plane, Renderer, Lens Distortion, and Enable
Image Plane in the camera.
The Animation menu allows you to choose between animating the camera and animating the
point cloud. Animating the camera leaves the point cloud in a locked position while the camera
is keyframed to match the live-action shot. Animating the point cloud does the opposite. The
camera is locked in position while the entire point cloud is keyframed to match the live-
action shot.
