User Manual

To work with the 3D scene, you can select the Merge 3D and load it into one of the viewers,
and then select the Camera Tracker Renderer and load that into a second viewer.
Viewing the Merge 3D shows the point cloud, ground plane, and camera.
When the Merge 3D is selected, a toolbar above the Viewer can add 3D test geometry like an
image plane or cube to verify the precision of the 3D scene and camera. You can then connect
actual 3D elements into the Merge 3D as you would any manually created 3D scene. The point
cloud can help align and guide the placement of objects, and the CameraTracker Renderer is a
Renderer 3D node with all the same controls.
Use the point cloud to accurately place different elements into a 3D scene.
At this point, there is no need for the Camera Tracker node unless you find that you need to
rerun the solver. Otherwise, you can save some memory by deleting the Camera Tracker node.
