VR is virtual reality technology, which is a technology that comprehensively utilizes computer graphics systems and various reality and control interface devices to provide an immersive feeling in an interactive three-dimensional environment generated on a computer; VR is "Virtual Reality" is the abbreviation of virtual reality, which is a computer system that can create and experience a virtual world.
The operating environment of this tutorial: Windows 10 system, DELL G3 computer.
VR (Virtual Reality, VR for short) was proposed by Jaron Lanier, the founder of the American VPL company, in the early 1980s. of. Its specific connotation is: a technology that comprehensively utilizes computer graphics systems and various reality and control interface devices to provide an immersive feeling in an interactive three-dimensional environment generated on a computer. Among them, the computer-generated, interactive three-dimensional environment becomes the virtual environment (Virtual Environment, VE for short). The carrier for the realization of virtual reality technology is the virtual reality simulation platform, namely (Virtual Reality Platform, referred to as VRP).
Technology Introduction
VR = Virtual Reality, virtual reality, or spiritual realm technology, is actually a computer that can create and experience a virtual world (Virtual World) system.
The so-called virtual reality, as the name suggests, is the combination of virtuality and reality. Theoretically, virtual reality technology (VR) is a computer simulation system that can create and experience a virtual world. It uses computers to generate a simulated environment and immerse users in the environment. Virtual reality technology uses real-life data and electronic signals generated by computer technology, and combines them with various output devices to transform them into phenomena that people can feel. These phenomena can be real objects in reality. , or it can be a substance that we cannot see with the naked eye, expressed through a three-dimensional model. Because these phenomena are not what we can directly see, but are the real world simulated through computer technology, they are called virtual reality.
Virtual reality technology has been recognized by more and more people. Users can experience the most realistic feeling in the virtual reality world. The authenticity of its simulated environment is difficult to distinguish between true and false in the real world, which makes people feel... An immersive feeling; at the same time, virtual reality has all the perceptual functions that humans have, such as hearing, vision, touch, taste, smell and other perceptual systems; finally, it has a super simulation system, truly realizing human-computer interaction , so that people can operate at will and get the most realistic feedback from the environment during the operation. It is the existence, multi-perception, interactivity and other characteristics of virtual reality technology that make it loved by many people.
Expand knowledge: Application fields
VR (virtual reality) technology can be widely used in urban planning, interior design, industrial simulation, historic site restoration, bridge and road design, We provide practical solutions for real estate sales, tourism teaching, water conservancy and electricity, geological disasters, education and training and many other fields.
In the field of advanced manufacturing, standing in front of the 3D image of a large aircraft engine, the strength of virtual reality that can be disassembled at will is clearly demonstrated. Operators can remove many parts of the virtual engine one by one and then enter the engine interior. "Virtual reality" realizes cross-platform interactive design, virtual display, virtual assembly, CAE data visualization and other functions, greatly improving the design efficiency of the design team, enabling R&D personnel to promptly discover and correct design defects and potential process problems, and improve Manufacturing success rate of product development.
Virtual reality technology is also of great use in the field of education and training. Create conditions for teaching functions that real experiments do not have or are difficult to complete. When it comes to high-risk or extreme environments, inaccessible or irreversible operations, high cost, high consumption, large-scale or comprehensive training, etc., virtual reality technology can provide reliable, safe and economical experimental projects. The G-Magic Virtual Reality Laboratory of East China University of Science and Technology is an example of virtual reality teaching in colleges and universities. The laboratory has a CAVE cave-like virtual reality system that can project works designed by college students onto walls, ceilings and floors. For example, if a student designs a shower room, he can use this system to display it in the lab as the same size as a real shower room. After creating this kind of teaching environment, teachers can more easily communicate with students about the design pros and cons of each link and make modifications at any time.
Some corporate training programs are also inseparable from virtual reality. Taking the petrochemical industry as an example, it is well known that large quantities of hazardous chemicals are concentrated in large petroleum irrigation areas. Improper handling may cause fires, explosions, and secondary disasters such as environmental pollution. Therefore, the government and enterprises have placed high demands on the safety of large-scale petroleum irrigation areas and the professionalism of operators. Virtual reality technology can build an emergency rescue and safety training system for storage tank areas. It can not only present various scenarios of the operation process to employees, guide them to learn and master safe operation skills, but can also simulate accidents and raging fire scenes, allowing employees to Conduct rescue operations in immersive virtual imagery.
