In-Depth Information
The main advantage of this approach is that, similarly to the pure holographic
displays, it is able to provide all the depth cues for multiple freely moving users
within a reasonably large field of view. Being projection based and using arbitrary
number of projection modules, this technique is well scalable to very high pixel
count and display size, not being limited to the resolution of a specific display
technology (like the ones using a single LCD panel). 2D compatibility is implic-
itly solved here, as light rays making up a 2D image are also easy to emit without
any reconfiguration. These systems are fairly complex because of the large num-
ber of optical modules and the required driving/image generation electronics.
The natural data format for this kind of display is the light field [57] that is pre-
sent in a natural 3D view. HoloVizio 3D displays are an implementation of this
technology [58, 59].
6 Conclusion
Very different ideas have been used so far to achieve the goal of displaying realis-
tic 3D scenes, the ultimate goal being a virtual 3D window that is indistinguish-
able from a real window. Most implementations of the approaches mentioned have
found their specific application areas where they perform best, and they are gain-
ing an ever growing share in visualization. 3D data is already there in a surpris-
ingly large number of industrial applications, still visualized in 2D in most cases.
As for home use, the natural progression of technology will bring the simplest
technologies to the mainstream first, and with advances in technology, cost effec-
tiveness and increased expectations regarding 3D will eventually bring more ad-
vanced 3D displays currently only used by professionals to the homes.
