Traditional museum display systems have some limitations in providing display content and interactive experiences, such as geographic location restrictions and space restrictions. The online virtual museum display system based on 3D virtualization technology provides users with a new way of display, simulating the exhibition and interactive experience of a real museum through a virtual environment. In this study, an online virtual museum display system based on 3D virtualization technology is used as the research object. By analyzing the characteristics and functions of the system, it discusses its advantages over traditional systems, especially in terms of stability. Performance. The research results show that the stability of the system is between 92% and 99%. A stable system can also build user trust and satisfaction in the system, and promote the establishment of long-term user relationships.
