Based On The Virtual Reality Ancient Architectural Three-dimensional Scene Construction Research And Implementation

With the wide range of application of computer technology, network technologyand virtual reality technology, combining virtual reality and digital ancient architectureis very important for the digital archives, heritage conservation and the online travel ofancient architecture. This paper studies the development process and some technicalproblems of3D roaming system of ancient architecture, analyzes the technical routeadopted by the system, and gives the overall design and the main process of the system,as well as the detailed design of function modules. At last, the paper achieves modelingand roaming of some the virtual scenes of the ancient architecture by giving some cases.In short, the study has some reference for modeling and roaming of other architecturalscenes.The main work of the paper is shown as follows:（1）It analyses the application status of virtual reality in ancient architecture,studies the classification and characteristics of ancient architecture, and summarizes thestructural features of ancient architecture as well as the components of the monomerancient buildings. Meanwhile, it also gives the analysis and comparison for theperformance, modeling techniques and methods of ancient architecture, and elaboratesthe severalparts of prophase, metaphase and anaphase of the technology route adoptedby virtual ancient architecture system.（2）It gives a roaming system of the ancient architectural based on virtual reality,and analyses for the requirements and functions of the system. It designs the systemarchitecture, the procedure and the three function modules which are data-collection andmodeling interactive roaming, from a user’s perspective.（3）It takes advantage some technologies, such as3ds max, Virtools, by givingsome ancient architecture cases, and completes the key modules, such as3-D scenemodeling, interactive roaming, collision detection, in the roaming system of ancientarchitectures. Meanwhile, the system can run smoothly in the test system.
