1. A method, comprising: acquiring, by a system comprising a processor, a first three-dimensional composite scene, the first three-dimensional composite scene including at least two three-dimensional scenes aligned in part based on a comparison of shape and visual appearance metrics in the at least two three-dimensional scenes; acquiring, by the system, a second three-dimensional composite scene, the second three-dimensional composite scene including at least two three-dimensional scenes aligned in part based on a comparison of shape and visual appearance metrics in the at least two three-dimensional scenes of the second three-dimensional composite scene; acquiring, by the system, shape and visual appearance metrics from the first and second three-dimensional composite scenes; and combining, by the system, the first three-dimensional composite scene with the second three-dimensional composite scene to form a third three-dimensional composite scene based on alignment of the first three-dimensional composite scene with the second three-dimensional composite scene, wherein the alignment is based on comparison of the shape and visual appearance metrics from the first and second three-dimensional composite scenes.
