Art deco building data collection and protection of nanjing based on 3D digital modeling technology -taking the site of China \& south sea bank Ltd for example

Art Deco buildings of Nanjing in the Republic of China constitute precious historical and cultural heritages in China. How to conserve such precious intangible cultural heritage and resources and carry forward characteristic Chinese culture by way of digital media art has become a scientific research subject demanding prompt solution. Based on the data modeling technology, the paper attempts to protect buildings of Nanjing constructed in the Republic of China and takes the site of China \& South Sea Bank Ltd as the example to fabricate 3D model library. Specifically, the paper first draws two-dimensional vector diagram by software such as Auto Cad on the basis of primary data, subsequently adopts MAYA for 3D modeling and eventually resorts Mental Ray rendering software to conclude static design sketch. Virtual reality scenes may be also accomplished by forming dynamic effects via MAYA.
