1、- 1 -附錄 附錄 A Research on Method of 3D Reconstruction of Ancient Architecture (Nanputuo Temple) [10]AbstractIn this paper, regarding the Great Majesty Hall of the NanPutuo Temple as a virtual modeling object, the research

2、 on the new technology of 3D reconstruction of the ancient architecture has been done, in which 3Ds Max and MultiGen Creator were applied. The conflict was solved between precision and the amount of data existing in the

3、process of 3D modeling virtual ancient architecture. The practical project has proved that the ancient architecture model made in this way has gotten living effect in roaming system, at the mean time it satisfies the dat

4、a demand of real-time rendering. Keyword： Virtual reality (VR), Ancient Architecture Protection, 3Ds Max, MultiGen Creator1. IntroductionVirtual Reality is a new man-machine interface. It provides users (participants) wi

5、th satisfactory immersed experience and multi-sensory channels, and attempts to seek the best way of man-machine communication. Using the virtual reality technology to realize the representation of ancient architecture i

6、s the innovation of architectural illustrational tools, and it is one of the hot topics of the present research. The lifelike computer modeling can not only demonstrate the profound cultural details of Chinese ancient ar

7、chitectures, but have practical significance to the protection of ancient architectures in form of archives, therefore it was applied more widely than the traditional physical model. The modeling fidelity and rapid real-

8、time data rendering are the foundations of - 3 -modeling, lofting, face modeling, NURBS face modeling, and other convenient and effective modeling method. It has a better ability of special effect processing and renderin

9、g. Using 3Ds Max you can determine precisely the size and the position of the model. After modeling, you can modify each component according to the actual need at any moment. Although 3Ds Max describes the objects' d

10、etails vividly, the large amount of the data of modeling cannot meet the need of real-time rendering. Compared with 3Ds Max, MultiGen Creator has less amount of modeling data. MultiGen Creator has the real-time functions

11、 of polygon culling 、logic culling 、priority drawing 、binary separating plane and so on. OpenFlight is the database format of Creator. It uses hierarchical structure of nodes to describe the database, so as to inform the

12、 image generator when and how to render real-time 3D scenes. Although Creator generates file on the small volume data, and has a rapid rendering speed, it cannot be comparable to 3Ds Max in fine modeling of single archit

13、ecture. Therefore, in fine modeling of complex ancient architectures, the best way is to model single architecture in 3Ds Max firstly, then import it to MultiGen Creator for simplification, and use key technologies such

14、as LOD, to satisfy the data demand of real-time rendering. 4. Modeling processes using 3Ds Max and MultiGen Creator In the actual construction process of ancient architecture, the components are divided into the followin

15、g five levels: column base level、fitment level 、tou-kung level、beam frame level and roof level. Each level comprises many timber components. These timber components not only have various shapes, but also have large amoun

16、ts. Therefore, the modeling method of taking the technology of integration of 3Ds Max and MultiGen Creator is more suitable for the modeling requirements of Chinese ancient architectures. Figure 1 shows the flow chart of
