Research and Application of Immersive Virtual Reality System Based on 3D Geographic Information System

Three-dimensional Geographic Information System (GIS) is the basic platform for data management and visualization of the internet of energy. The display medium of three-dimensional scene is generally a two-dimensional screen. The visualization of three-dimensional scenes lacks visual immersion and reality, which is difficult for two-dimensional screen to meet the requirements of large-scale, high-dimensionality and Multi-type energy internet data visualization. Combining the features of three-dimensional Geographic Information System and Cave Automatic Virtual Environment(CAVE) virtual reality system, this paper discusses the key technology of developing the Cave Automatic Virtual Environment immersive virtual reality system with three-dimensional Geographic Information System as the basic platform, the immersive virtual reality system and environment based on three-dimensional Geographic Information System is realized to help users understand the data and present the spatial knowledge more effectively. Finally, combined with the promotion and application of the system, the next research direction is discussed.
