There are now cameras which allow to take a bunch of pictures to get automatically a 3 dimensional representation of the situation. This needs quite a bit of mathematics, also multivariable calculus. On a computer graphics level, one has to match different frames of the movie. Then there is some geometry needed to get a three dimensional picture. This technology is still in its infancy. There is a stereo camera of Fuji which has two lenses with 10 Megapixel sensors. Sony uses sweep panorama technology, mostly to compute panoramas. The actual 3D scene generation is not yet impressive but theoretically. It should be possible to get a lot of 3D information from a movie especially if the photographer moves too. This is the structure from motion problem.
