The first virtual reality was called Virtual Reality Modeling language and it was introduced in 1994. It was invented for the virtual world without any dependency on headphones. Web3D consortium was found to develop the industry standard of web-based 3D graphics. This Online Amazing Race consortium simultaneously develops the X3D from the VRML framework. It was an open-source standard and as an archival for web-based distribution in VR content. JavaScript application programming interface (API) uses the WebVR as an experimental purpose that will support different VR devices like vibe, the Google board, Oculus rift, and over in a browser. New virtual reality headset display is dependent on technology for smart phones that include hand position body position, display, and fast, lightweight, and small processor in a computer.
VR features
This will leads to independent VR developers to afford and go to start the Oculus Rift as the first independently developed VR headset in 2012. VR images and videos are increased in independent production with the development of unidirectional cameras at an affordable price. It was called a 360-degree camera or VR camera. It used to record 360 photographs with very low resolution in higher compression format. It is also used for 360 videos for online streaming. In overall contrast, photogrammetric is raised to combine a lot of high-resolution photos for creating well-detailed 3D object and environment in VR application. Special output devices are used to display the virtual world. Cave or head-mounted display is the well-known formats. To show the special features like partial impression, different images are generated and display from a different perspective. Different technologies are used to bring accurate images to the right eye and more technology will become in the future at right time. The distinction is based on passive and active technology. To interact with the virtual world some special devices are used. Such input devices are wired gloves, 3D mice, optical tracking sensors, and motion controllers. Commonly controllers use it in an optical tracking system for navigation and location. From this process, the user can move or walk or run without any disturbance of wiring. Some input devices will force the user to get feedback for having or other parts of the body. From these steps, humans can orient themselves in the 3D world from sensory and hepatics technology, Sensory sensation, and realistic simulation. It allows the user to view the sense of direction in an artificial landscape. Omnidirectional treadmill obtains from haptic feedback additionally and also suits and vibration gloves.360-degree panorama videos are used to create VR photography from virtual reality cameras. These 360-degree camera shots were mixed with virtual elements to combine fiction and reality through special effects. There are lots of VR camera with the different format are available and contain more lens that is installed in the camera. The more reality comes closer to us the more engaged we are to the virtual world. Though VR camera has lot of pros and cons to the current booming technological world the individual contact between person are getting farther than expected. These are the unbearable facts hidden behind the modern technology.
