Virtual reality technology has brought new vitality to the display of museum exhibits. With the vigorous development of virtual reality technology, the application of virtual reality technology is becoming more and more frequent. Now, the application of virtual reality technology can be seen in many museums. This paper is aimed at using virtual reality technology to study the exhibition space and interaction design of museums. This paper proposes a virtual space display technology based on the octahedral projection method and hemisphere projection method and investigates and analyzes the application of virtual reality technology. Although the realism of the virtual display is not as good as that of the traditional display, it can be improved in terms of technology and other aspects in the future.
