Research on the application of virtual reality technology in contemporary environmental design

The development and application of virtual reality technology can help the innovative application of environmental design. This paper first focuses on the application of virtual reality technology in the natural environment based on the development of environmental design and the integration of natural geographical conditions. In fact, the focus is on the analysis of virtual reality technology. Selected 3D reconstruction technology algorithms, including camera calibration profile, pair of polar geometry and single response matrix, matching cost and quality assessment index. Finally, the natural environment simulation experiment is constructed based on virtual reality technology. The average real-time rendering FPS of the unoptimized vegetation distribution interval decreases continuously with the increase in the number of vegetation models. When the average vegetation number is around 54,672, the average FPS decreases to around per 53. When the average vegetation count is at 97,713, the average FPS drops to about 28 frames per second. The average real-time dye FPS stabilizes at around 50 after using the LOD multi-detail hierarchical model.
