Today, I would like to introduce the concept of BIM peripherals by focusing on VR, or Virtual Reality. VR, a term coined by Jaron Lanier, founder of VPL Corporation in the early 1980s, refers to technology that extensively uses computer graphics systems and various interface devices, such as reality and control tools, to create immersive experiences within interactive 3D environments generated by computers. This computer-generated, interactive 3D space is known as a Virtual Environment (VE). The platform that supports VR technology is called the Virtual Reality Platform (VRP).
Virtual Reality technology has a wide range of applications across multiple fields, including urban planning, interior design, industrial simulation, historical site restoration, bridge and road design, real estate sales, tourism education, water conservancy and power management, geological disaster management, education, and training. It offers practical and effective solutions tailored to the needs of these industries.
In advanced manufacturing, VR truly shines. Imagine standing in front of a 3D model of a large aircraft engine, able to remove components at will. This capability highlights the strengths of virtual reality technology. Operators can disassemble many parts of the virtual engine one by one and even explore its interior. VR has enabled cross-platform interactive design, virtual display, virtual assembly, and CAE data visualization, significantly enhancing the efficiency of design teams. It allows R&D personnel to promptly identify and correct design flaws and potential process issues, ultimately improving the manufacturing success rate of new products.
Virtual reality also holds great promise in education and training. It enables teaching scenarios that are either impossible or difficult to replicate in real life. When dealing with high-risk or extreme environments, inaccessible or irreversible operations, costly or resource-intensive procedures, or large-scale comprehensive training, VR technology offers safe, reliable, and cost-effective experimental opportunities. For example, the G-Magic Virtual Reality Laboratory at East China University of Science and Technology features a CAVE-style VR system that projects student designs onto walls, ceilings, and floors. A student designing a shower room can display it at full scale within this virtual space. This immersive setup allows teachers and students to discuss design strengths and weaknesses conveniently and make modifications in real time.
Many corporate training programs also benefit from VR technology. Take the petrochemical industry as an example: large petroleum irrigation areas contain hazardous chemicals, and improper handling can cause fires, explosions, and secondary disasters such as environmental pollution. To ensure safety and operator expertise, governments and companies have set strict standards. VR can be used to build emergency rescue and safety training systems for tank farms. These systems present various operational scenarios to employees, guiding them to learn essential safety practices. They also simulate accident and fire scenes, allowing workers to perform rescue operations within immersive virtual environments.
That concludes this introduction to VR and its role as a BIM peripheral concept. I will continue to introduce other related concepts soon, so stay tuned.
