| Virtual Reality is one of the newest technology in the field of computer in the 1990s.And it is being applied on architectural design field these years. It is important to keep ancient architecture in digital archive, protect culture relic by VR and computer technology. It is a popular research direction in the combination of the appliance of virtual reality technology and the protection of culture heritage of architecture at present.In this dissertation, analyzing ancient architecture features in the foundation, taking the Majesty Hall and the Dabei Hall of Xiamen Nanputuo temple as the example, research deeply on the step which is suit to set up ancient architecture virtual scene and scene integration. On the basis of modeling ancient architecture, carries on the key technologies in modeling process, has studied the geometry optimization techniques and the texture optimization techniques with emphasis. The optimized technique of modeling is also efficient for large and complicated simulation scene. Finally, using the WireFusion platform and toolbox, develop the real-time roaming virtual system based on Internet. The result shows that this system has made satisfactory results in the aspects of the drawing effect and running speed.These are three parts of this dissertation. First, the feature of virtual reality technology and review of the present method of architecture presentation are introduced. It proves that VR is necessary and reliable to represent architecture as a new method. Second, virtual scene modeling process and the technical specification are analyzed, carries on the modeling process taking this as the standard, The thorough discussion uses the key technologies in the modeling process. In the third part, the practical project has proved the ancient architecture virtual scene modeling technique proposed in this dissertation is feasible and valid, which is applied in Xiamen Nanputuo temple virtual roaming system. |
