Case study of 3D Interactive Design of Nanjing Tongji Gate Wall

Through the case study of 3D interactive design of Nanjing Tongji Gate Wall, this paper explores the application of 3D interactive design in relic visual reconstruction. This paper collects literature on Nanjing City Wall and conducts field research and interviews about Tongji Gate. On the basis of relevant data and literature, 3D interactive technology is used to design the interactive animation system of Tongji Gate. 3D interactive animation contributes to the visual reconstruction of material cultural heritage, the improvement of traditional cultural relics protection and research, the adaptation to communication and promotion in the new media era, the protection of cultural heritage, and the continuous cultural inheritance.
