Research On Parametric 3D-Modeling And Virtual Reality Of Chinese Traditional Building

Through wide application of computer technology, how to digitalize the Chinese traditional building and protect them by Virtual Reality (VR) has become a new research field. Recently our research concentrates on the modeling and animation for the instance of the Chinese traditional building. How to explore universal modeling system has been an important project.Yingzao Fashi, a book published in the North Song Dynasty, has modularized the design standard of Chinese traditional building, and makes the research project possible. We investigated the feature of Chinese traditional building model (for example, Dougong model), and presented the approach of Parametric-Modeling for the Chinese traditional building with the Parametric-Design based on construction.(1)Through researching the architectural principle of polyline, we proposed the Parametric-Definition of closed polyline and the evaluation of bugles, and therefore realized the automatic generation of the closed polyline.(2)We proposed the Parametric-Definition of primary transform by analyzing homogeneous coordinate system, and thus obtained the Parametric-Definition of transform matrix.(3)Through analyzing the generating methods of extrude-solid and considering the process of setting up the 3D-model, we gave the Parametric-Design of primary solid.(4)After investigating the principle of Constructive Solid Geometry (CSG) and experience of the 3D-model construction, using the algorithm of Travel-Left-First, we presented the four-element Parametric-Definition of the generation, and finally obtained the Parametric-Modeling algorithm applicable to the Chinese traditional building.(5)After defining ESTL file and studying of Entity Extended Data (EED), we developed the modeling system and the VR platform of the Chinese traditional...
