Research on Green and Low-Carbon Design of Hainan Rural Residences Based on VR Technology

In order to realize the goal of green and low-carbon design of Hainan rural residence, this paper, based on VR technology, researches and designs the Hoppe algorithm of scattered point cloud data, bidirectional reflective distribution function (BRDF) of data processing and real-time realistic rendering technology in the process of structured mesh generation, and real-time realistic rendering technology in the indoor visualization design system of residential house. Secondly, by screening the experimental scenes, the differences in the perception of the screened scenes are analyzed from the perspectives of public gender, education and profession. Finally, the application effect of VR technology in Hainan rural residential design is compared and analyzed. The results show that the ratings of males on the four indicators in the LP group are 3.08, 3.37, 3.23 and 3.49, respectively, and the ratings of females are 3, 3.68, 3.51 and 3.78, respectively.The ratings of undergraduates on each indicator are higher than those of postgraduates and above in the PP group, the DP group and the SE group. The scores of all indicators on the LP group of the professional population were lower than those of the non-professional population. The use of VR technology can allow users to produce visual, auditory, and tactile changes at the same time, but also to display static and dynamic space, and to do the interaction of the scene. Its display effect is better than other programs. The average satisfaction of the public with the 8 aspects of VR technology design residential houses is greater than 80%. Obviously, VR technology has advantages in the green and low-carbon design of Hainan rural residence.
