It plays an important role in optimizing the construction design scheme and improving the science and rationality of the architectural design. In order to realize the effective application of virtual technology in the future architectural design, it is necessary to intensify the research on its application and give full play to its application value and advantages. This paper discusses and analyzes the application and realization of virtual reality technology in the future architectural design, and predicts its future application prospects.展开更多
