Virtual Reality is a technology that has grown in importance since the beginning of the 1990s. The term owes at least some of its notoriety to the book « Virtual Reality : Exploring the Brave New Technologies of Artificial Experience and Interactive Worlds from Cyberspace » (1991) from Howard Rheingold. It addresses the future technical possibilities of Cyberspace, as well as to experience artificial realities in virtual worlds. Howard Rheingold is a visionary who had as early as the 1980s already delved into the related applications of the personal computer in his book « The Virtual Community » for the first social networking experiences.

What are the processes used today for stereoscopic imaging? What is stereoscopic 3D & how does it work ?
Virtual reality quickly became a motor for the game industry and is the origin of the current boom in 3D with realtime 3D, 3D glasses, 3D displays, and 3D projectors for 3-dimensional vision filled with functions such as 3D tracking for game input.
VR in Industry
Already at the beginning of the 1990s, virtual reality was already used for various applications in science, the military, and industry for which the development has continued up to today.
In professional applications, VR is also known under the labels « 3D Visualisation » or « Virtual Engineering ». It is applied notably in product design, product development, training and marketing.
Communication via virtual reality techniques benefits ideally from a common database of design information and allows the presentation of alternatives for particular design requirements or specialized projects. During the stages of design and development, simulations allow for the optimisation of both the products and the processes. With such capabilities, a client can select very early products from a digital catalogue or even configure the product himself.
Successful application of VR began with virtual models in design which replaced classic models from metals, woods, or other materials requiring significant effort, time and costs to generate. Give the high costs, the need for multiple models, and the time delays, using digital mock-up models and VR techniques allowed for rapid evaluation and modifications leading to a significantly accelerated and less expensive design cycle.
Simulations of digital models serves to eliminate errors and optimise the product design and production saving enourmous costs and schedule delays due to design errors.
Studies of the assembly, service and the production process of the design play an important role in the production optimization. The savings of time, materials, and money are considerable if it is possible to verify the interactions in a precise and realistic manner using virtual models. For example, during the development of a new helicopter, the American manufacturer, Sikorsky, could – thanks to VR technologies from Haption – could test accurately the assembly and maintenance processes using a 6D force-feedback system with real-time collision detection, and thereby eliminate errors in the design and production using a virtual model that would have cost $18 million to build.
