The CAVE (Cave Automatic Virtual Environment) projection system, proposed in the United States in 1992, is an immersive virtual reality system consisting of three or more rigid rear projection walls. It integrates multi-channel visual synchronization technology, stereoscopic projection display technology, 3D computer graphics technology, and sound sensor technology. A 3D tracker enables six degrees of freedom motion tracking of the user's head and interaction with virtual objects.
This system can display 1:1 digital prototypes, featuring accurate perspective, distortion-free display, and multi-sensory fusion capabilities. It supports coordinated perception of vision, touch, and sound, and is primarily used in product evaluation, industrial simulation, and biomedicine.
Later, as microcomputer graphics processing capabilities improved, the system evolved into a distributed microcomputer system. Since the first system was established at New York University in 1994, it has been deployed in over 600 universities and research institutions worldwide, covering applications such as virtual prototype design and aerospace simulation. Future development will focus on intelligent and interactive evolution, introducing IoT technology for remote monitoring and expanding haptic feedback and immersive sound field reconstruction capabilities.
CAVE is a large-scale VR system, but its high cost, ranging from hundreds of thousands to millions of dollars, has historically limited its widespread adoption. This has been largely due to the use of high-end SGI workstations and multi-channel graphics systems, making it unaffordable for most users. However, in recent years, with the continuous improvement of microcomputer performance and graphics rendering capabilities of graphics accelerator cards, the AGP bus has broken through the 33MHz limitation of the PCI bus, significantly enhancing the performance of microcomputer graphics accelerator cards and making it possible to replace expensive SGI workstations with distributed microcomputer systems.
The CAVE system is a room-based projection-based visual collaboration environment based on multi-channel visual synchronization and stereoscopic display technologies. It provides a room-sized, four-sided (or six-sided) cubic projection display space for multiple participants. All participants are fully immersed in an advanced virtual simulation environment surrounded by stereoscopic projection images. With the help of corresponding virtual reality interactive devices (such as data gloves, force feedback devices, and position trackers), they experience immersive, high-resolution 3D stereoscopic audiovisual images and a 6-DOF interactive experience. Because the projection surface can cover almost the entire user's field of vision, the CAVE system provides users with an unprecedented and immersive experience. The CAVE projection system is a highly immersive virtual demonstration environment composed of three or more rigid projection walls. Combined with a 3D tracker, users can closely interact with virtual 3D objects within the system surrounded by projection walls, or freely roam within a "realistic" virtual environment. CAVE systems are generally used in high-standard virtual reality systems. Since the first CAVE system was established at New York University in 1994, CAVE has been widely used in over 600 universities, national science centers, and research institutions worldwide.
Based on its fully immersive display environment, CAVE offers scientists a groundbreaking and innovative way of thinking, expanding human cognitive abilities. Scientists can directly see their ideas and research objects.
For example, atmospheric scientists can "drill into" the eye of a hurricane to observe the complex and chaotic structure of the air; biologists can examine the structure of DNA chromosomes arranged in a regular pattern and virtually disassemble gene chromosomes for scientific research; physicists and chemists can delve into the microscopic structure of matter or vast environments to conduct experiments and explorations. In short, CAVE can be applied to any virtual simulation application requiring immersion, representing a novel and advanced means of scientific data visualization.
CAVE (Cave Automatic Virtual Environment) is a virtual reality system that uses a projection system to surround the observer, displaying multiple images. Multiple projection surfaces form a virtual space.
Theoretically, CAVE integrates high-resolution stereoscopic projection technology, 3D computer graphics technology, sound technology, and sensor technology based on computer graphics to create a fully immersive virtual environment for multiple users.
