1. A method of automatically generating a three-dimensional (3D) video of a scene, the method comprising: measuring a first plurality of 3D coordinates of the scene with a 3D measuring instrument placed in a first frame of reference, the 3D instrument being placed in a first position; measuring a second plurality of 3D coordinates of the scene with the 3D measuring instrument placed in a second frame of reference, the 3D instrument being placed in a second position different than the first position; registering the first plurality of 3D coordinates and the second plurality of 3D coordinates together in a common plurality of 3D coordinates, the common plurality of 3D coordinates being in a common frame of reference; determining by a processor a trajectory path, the trajectory path having a plurality of trajectory poses for a corresponding plurality of trajectory points on the trajectory path, each trajectory pose having a trajectory position and a corresponding trajectory direction, the trajectory path and the plurality of trajectory poses based at least in part on the first position, the second position, and a first mathematical algorithm; generating for each trajectory point a two-dimensional (2D) image based at least in part on the corresponding trajectory pose and the common plurality of 3D coordinates; generating the video based at least in part on the generated 2D images; and displaying the video on a display device.
