We present a method of reshaping light in three dimensions via phase modulation. The method calculates the target computer-generated hologram individually and adds to it an appropriate transfer function to translate the reconstruction to any location in space. We are able to simultaneously generate independently controlled arbitrary patterns at different positions using a single laser beam.
