Implement Multi-Character Display in Virtual Reality Environment Based on Unet and Tracker

Power grid operation is a very safe operation site, it is very important to be able to carry out related operations in accordance with the safe operation process, the existing traditional safe operation process, mainly in the traditional teaching mode or simulated real scene operation mode. In the links of management and training, operators lack intuitive experience and interaction, and they are not enough to show the serious consequences of illegal operation; As the head-mounted display becomes the most important interactive virtual reality display device, the 3d interactive display and the expressive force of the game engine are gradually improved, significantly improving participants’ sense of immersion. Virtual reality technology can be used to build a simulation teaching platform for authentic visual experience, authentic representation of work flow and convincing interactive feedback. Virtual reality technology is used to establish a practical environment for grid operation in the virtual three-dimensional space of the computer that integrates class a illegal operation events. Users participating in the learning practice can operate in the virtual space according to the process. In this paper, based on unity built-in HAPI unet and third-party plug-in VRTK, the complex interaction of large-scale training business process is realized. Through VRTK, steam VR interface, the handle button state is obtained and information is transmitted on multiple instances, so as to determine the transfer and pickup state of interactive objects.
