This work combines three-dimensional roaming with museums to build a virtual roaming museum, reproduces the physical exhibition of the museum for the audience online, and improves the effect of online exhibition. The production process first analyzes and studies the scene design; then determines the modeling method according to the existing model and selects the appropriate model and parameters and the production process; finally, uses the three-dimensional animation modeling technology to complete the virtual reproduction of the architectural style in the two-dimensional space, and uses the software function to make the cultural relics "resurrection" to simulate the original reality. It is hoped that through the research and design of this paper, it can contribute a little to the construction of digital museum, change the way the audience visits the museum, and make the museum more affinity and more infectious.
