Hologram production techniques can combine source data representing
realistic information describing an environment with source data
providing representational information describing a feature of the
environment and/or some object interacting with the environment. The
combined data is used to produce holograms, and particularly holographic
stereograms including features that enhance the visualization of the
environment depicted in hologram. A haptic interface can be used in
conjunction with such holograms to further aid use of the hologram, and
to provide an interface to secondary information provided by a computer
and related to the images depicted in the hologram.
