In order to represent complex three-dimensional environments instantly time, efficient output devices are required. When displaying a stereo image on a screen, special glasses in many required. But a new generation of displays provides greater flexibility while maintaining high image quality - even without glasses!
Immersion is the state of consciousness where an immersant's awareness of physical self is diminished or lost by being surrounded an engrossing total environment; often artificial1.
In order carryout a feeling of immersion, a perfect interplay of various components is needed - software and hardware must be perfectly matched. The representation of complex three-dimensional environments in live represents a great challenge for online marketing electronic devices. Amazingly, a German company direct from the black Forest in South Germany, offers merely the displays which works with this applications and the best about it, they work without glasses.
3D technology is everywhere interesting, where it's important to present a simulated reality and its physical properties in an interactive manner. Whether in industrial design, in the medical sector or in edutainment, the 3D without glasses visualization opens up entirely new possibilities for most industries dealing with virtual reality.
So far, however, this particular part of the 3-D technology looks like immature. Due on the necessity of auxiliary means such as anaglyph glasses ( Red-Green-Glasses) or shutter glasses to few companies seem to question if this technology can provide a realistic added value. Of which this has now developed. A German company from the Black Forest developed with been producing since 2006 autostereoscopic 3D displays: Glasses-free three-dimensional vision. The TRIDELITY AG has been pioneering in the development of this cutting edge technology and provides 3D without glasses with high excellence. But how does the spatial representation really work?
Biology as a model
From age eight months, human beings are rrn a position to physically see and detect depth variations. This stereoscopic vision arises from a complex interplay between the two eyes as well as the brain. Our eyes are slightly offset from additional and therefore watch a scene from two different perspectives.
Having a pair of perspectives, mind is fortunate to calculate a spatial image in expertise of the information of the viewing length. The 3D Monitors exploit this principle by projecting multiple images simultaneously. An extraordinary filter called parallax barrier separates these perspectives and ensures that every one of our eyes get slightly different image which represents a shifted perspective of the scene.
This filter can be thought of as sort of slanted stripe-mask, which is mounted ahead of the display: The lighting of each pixel thus remains deflected in various directions. In order to get the 3D effect the three-dimensional content to be shown must in order to previously recorded from all of the perspectives too. On a special Liquid crystal display all different perspectives or pictures are displayed at the same time nested together according with certain sub-pixel pattern (multiplexed). The shade of the image is then separated again by the specially developed filter element, the parallax barrier, and appearance to the viewer as three dimensional.
Different viewing angles
Autostereoscopic 3-D displays differ depending for the application: Television . is built on either targeting there is or spreading the 3D representation a lot of users. Single-view displays, currently being the name suggests, are optimized for a single-user. The strengths in the single-view displays are inside high resolution and the optimal image separation of the average perspectives. At one hand, this leads to a higher achievable 3D depth, on one other hand, furthermore, it permits the perception of very small depth distinctions. Exact this property is extremely in many applications similar to the design and construction.
For optimal 3D effect and to protect yourself from spatially inverted impressions on a single-view display, the user's eyes end up being exactly placed within the stereo zones (sweet-spot). Optionally, a tracking system used in order to adjust the sweet spot constantly according for the movements from the viewer which is detected the camera; The positioning of the viewer and also the processing of data will be without just about any delay: Consumer can move freely watching the monitor without having to suffer connected with image best. The Single-Viewer technology is therefore predestined for your desktop usage and as point understanding (POI).
In contrast, the multi-view displays are designed for situations that will multiple observers should perceive a three-dimensionally experience also consider while maximizing the freedom of movement, for example in group meetings or client presentations. This freedom is reached by projection greater two perspectives at duration. The drawback however is this particular process decreases the resolution by more than 50% on five-views systems and by 75% within the eight. This resolution loss is however compensated the actual additional 3D information.
Symbiosis between display and software
Virtual Reality (VR) is employed in many applications because it make easy to experience abstract data while allowing direct interaction. Problems that do definitely not exist are set up visible, permitting us to comprehend complex issues intuitively. Good VR systems form the cornerstone for the practice usage where the parts displaying, tracking and interacting must be finely tuned to additional.
Most recently TRIDELITY along with the software manufacturer TechViz presented at a year's fair 'Laval Virtual France' any VR solution: A newly-developed tracking method allows the user to control a virtual 3D model using a 20 x 20 centimeter cube interactively while showing it in 3D without glasses. The cube is recognized by a number of reflectors installed on the cube's surface. A camera attached with the top of the display recognizes these markers and processes their position in real-time. This perfectly coordinated interaction of the parts is an effective example how the current regarding the art technology marks the beginning of another era on 3D creation. The same solution become presented 12 months at the Siggraph in Vancouver, Canada together by using a glasses-free 4K 3D Monitor without glasses.
Maximum benefit is achieved through user-friendly applications that integrate seamlessly into the processes of a company. The TRIDELITY VR solution creates a higher volume of user friendliness in having 3D visualization software by providing a plug & play and compact solution.
Moreover, this solution has already been compatible with virtually all commercially available visualization software and therefore interesting for many people different business.
TRIDELITY's 'TT driver' allows the visualization of 3D content without conversion of info. Already by simply installing it on a workstation, feasible to to reproduce content on the 3D display autostereoscopically. The adaptation of the application is not necessary: Since of the simple fact that most for this existing professional 3D applications are based on the open graphics library (OpenGL) vehicle driver has some is placed between use and the library working like an alternative autostereoscopic covering. Due to this compatibility, the upgrade through a 3D package (display plus software) the significant added value to companies: 1 side hand, upgrading of the existing software to real 3D representation and the other one the increased labor productivity for
the various tasks within product life cycle. The acquisition in the 3D without glasses option would be for companies in the industrial sector a future-proof property. Based on the steadily increasing user-friendliness, the growing usage fields and growing demand from employees, its probably easy to access . matter of time, until glasses-free 3D visualization becomes a cross-industry standard for augmenting constructing and design tasks.
